Aire One Heating & Cooling has been a licensed heating, cooling and indoor air quality contractor in Ontario since 1990, working across Markham, Richmond Hill, Vaughan, Thornhill, Scarborough, North York and Toronto from 2800 John St, Unit 9, Markham. Twenty four hour line: 310-4328.

The short answer. Dirty air filters are the most overlooked cause of weak summer cooling. A clogged filter blocks the airflow your air conditioner needs to pull heat out of your home, so it cools weakly, runs longer cycles, and can ice up the indoor coil until it stops cooling at all. ENERGY STAR says to check the filter every month during heavy-use months and change it at a minimum every three months. Whether that saves you a specific percentage on an Ontario hydro bill is a claim nobody can make honestly, and section .03 explains why.

What the filter is actually there for

Most people assume the filter is there to clean the air they breathe. That is a side benefit. Its first job is to protect the machine.

Your indoor unit pulls household air across a cold evaporator coil, the finned surface that absorbs heat and moisture out of the air. The filter sits in front of that airflow and catches dust, lint, pollen and pet hair before they land on the coil. Carrier, whose equipment we install, puts it plainly: the filter traps pollutants that would otherwise coat the components and choke the machine from the inside.

That gives the filter two jobs that pull against each other. It has to be dense enough to catch particles, and open enough to let air through. When it loads up with debris, the second job fails first, and the whole system feels it.

What a clogged filter does to summer cooling

Airflow is not one symptom among many. It is the thing everything else depends on. When it drops, the failures arrive in order.

Weaker cooling first. Less air across the coil means less heat carried out of the house per minute. On a mild day you may not notice. On the hottest afternoon of the year, the system simply cannot keep up, and the thermostat never reaches its setting.

Longer run times next. The thermostat measures temperature, not effort. It keeps calling for cooling because the target is never met, so the system runs and runs. This is the part homeowners misread as a dying air conditioner.

Then ice. This is the one that surprises people. Restricted airflow lets the coil drop below freezing, and the moisture condensing on it turns to ice. A frozen coil blocks airflow further, which makes more ice. Cooling stops completely, and the melt can leave water where you do not want it. If you see ice, shut the system off at the thermostat and leave the fan running to thaw it.

And dirt where it does not belong. ENERGY STAR notes that a clean filter also keeps dust and dirt from building up inside the system, which is what leads to expensive maintenance or early failure. Once the coil itself is coated, a new filter will not undo it. That is a service call with tools.

The 5 to 15 percent figure, and what happened to it

If you have read anything about air filters, you have seen this sentence: replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5 to 15 percent, according to the U.S. Department of Energy. It is on hundreds of HVAC company blogs. It was in the earlier draft of this very page.

We went to check it on 17 July 2026. Here is what we actually found.

The number is real, but its source page is gone. The URL that nearly every site cites for it, energy.gov/energysaver/maintaining-your-air-conditioner, now returns a 404. The Department of Energy’s current Energy Saver page on air conditioner maintenance describes the mechanism, that dirty filters reduce airflow and let dirt reach the evaporator coil, but it no longer publishes the 5 to 15 percent figure at all.

The figure does still exist in a DOE-hosted document: the Energy Saver 101 home cooling infographic, which states that routinely replacing or cleaning your air filters can lower an air conditioner’s energy consumption by 5 to 15 percent. That PDF carries no publication date and sits on a legacy path.

And the citation chain is drifting. Carrier Canada’s own air filter page still quotes the figure, footnotes it, and that footnote links to the dead DOE URL. Carrier also restates it as a 5 to 15 percent increase in efficiency, which is not the same claim as a 5 to 15 percent reduction in consumption. Those two sentences describe different arithmetic.

So here is our position, and you can hold us to it. The figure came from the DOE, it is a reasonable order of magnitude, and we have no better one. But it is a United States estimate with no stated test conditions, no date, and no Ontario context. It was never a promise about your hydro bill, and anyone who prints it next to a dollar amount for your house is guessing.

What is worth doing does not depend on the number. A filter costs a few dollars and five minutes. The coil it protects, and the compressor behind that, do not.

Month between checks, per ENERGY STAR

Months, ENERGY STAR minimum change

MERV, EPA floor for an upgrade

Top of the MERV scale, per Carrier

How often to change it

There is a floor and there is a judgement call. The floor comes from ENERGY STAR: check your filter every month, especially during heavy-use months such as winter and summer, and if it looks dirty after a month, change it. At a minimum, change it every three months.

The judgement call is everything else, and it depends on your filter and your household.

Carrier also lists what shortens every one of those intervals: poor indoor air quality from smoking, candles, a wood stove or nearby construction; allergy or asthma sufferers in the home; multiple pets; a larger home moving more air; and heavy use, including running the fan continuously. If two or three of those describe your house, treat 30 days as the interval and stop reading charts.

One habit beats any schedule. Write the date on the cardboard frame with a marker when you install it. The guesswork is the actual problem.

MERV, and why higher is not automatically better

MERV stands for Minimum Efficiency Reporting Value. It is the industry scale for how well a filter traps airborne particles, and it runs from 1 to 16, with 16 catching the most. The word minimum matters: it reflects the filter’s worst-case performance in testing, not its best.

The U.S. EPA’s guidance is that if you upgrade, choose a filter rated at least MERV 13, or as high as your system fan and filter slot can accommodate. The EPA also notes that filters rated MERV 13 and above must demonstrate at least 50 percent removal efficiency for the smallest particles tested.

Now the part the filter aisle does not tell you. A denser filter is harder to pull air through. Push the MERV higher than your blower and your filter slot were designed for, and you recreate the exact problem this article is about: restricted airflow, weak cooling, a coil that wants to freeze. The EPA’s own wording carries the escape hatch, “as high as your system can accommodate,” and it says you may need an HVAC technician to work out what that is. Carrier suggests MERV 12 to 16 specifically for homes with allergy or asthma sufferers, which is a different question from what your ductwork can breathe through.

Read this before you upgrade. A high-MERV filter in a system that cannot handle the pressure drop is worse than the basic filter it replaced. If you want better filtration, the right move is usually a thicker filter with more surface area in a proper media cabinet, not a denser one crammed into a 1 inch slot. Ask before you buy, not after the coil ices up.

What a clean filter cannot fix

We sell air conditioners and we service them, so take this section as the one where we argue against our own marketing. A filter change is the cheapest thing you can do, which is exactly why it gets oversold as a cure.

A fresh filter will not fix any of these:

• An undersized or badly installed system. If the equipment was wrong for the house on day one, no filter changes that. It will run long cycles forever.
• Low refrigerant. Refrigerant is not consumed. If the charge is low, there is a leak, and topping it up without finding the leak is throwing money into the air.
• A coil that is already dirty. Once dust has bypassed a loaded filter and coated the evaporator, cleaning it is hands-on work. A new filter stops it getting worse and does nothing about what is already there.
• Leaky or undersized ducts. Air lost into an attic or crawlspace never reaches a room. ENERGY STAR estimates sealing and insulating ducts can improve system efficiency by as much as 20 percent, and that is a separate job.
• A failing compressor or blower motor. Poor airflow shortens their lives. It does not resurrect them.
• Humidity you can feel. If the house is cool and still clammy, that is usually sizing, run time or ventilation, not filtration.

If you changed the filter and the house still will not cool, the filter was not the problem. That is useful information, and it is worth more than another trip to the hardware store.

When to call a licensed technician

Changing a filter is a five minute job you should do yourself. Shut the system off at the thermostat, find the filter in the return-air grille or at the indoor air handler, note the size printed on the frame, slide the old one out, slide the new one in with the airflow arrow pointing toward the blower, and write the date on it.

Call someone when the symptom outlives the filter. Ice that returns after a thaw and a fresh filter. Cooling that is still weak with a clean filter in place. Grinding, screeching or short cycling. Water where the indoor unit lives. Rising indoor humidity. Those are airflow, charge or component problems, and in Ontario the work on them is licensed for a reason.

If you are weighing bigger equipment questions rather than a filter, we have written up what heat pumps actually cost in Ontario and how heat pumps behave in the GTA with the same accounting we used above.

Questions we get asked

Can a dirty filter stop my air conditioner from cooling completely?

Yes. Dirty air filters are one of the most common reasons an AC stops cooling: restricted airflow lets the evaporator coil drop below freezing, and condensing moisture turns to ice on it. Once the coil is iced over, airflow stops and so does cooling. Shut the system off at the thermostat, let it thaw, and fit a clean filter. If the ice comes back, the filter was a symptom and not the cause, so call a technician.

How often should I change my filter during an Ontario summer?

ENERGY STAR says check it every month during heavy-use months and change it at a minimum every three months. Carrier says a basic 1 inch fibreglass filter should be checked and probably changed about every 30 days, while a 4 inch pleated filter can last from 3 months to a full year. Homes with pets, allergy sufferers, smokers or a wood-burning fireplace should work to the shorter end of every range.

Will changing my filter lower my hydro bill by 5 to 15 percent?

Nobody can tell you that honestly. The 5 to 15 percent figure comes from a U.S. Department of Energy infographic that carries no date, and the DOE page that most sites cite for it now returns a 404. It is a reasonable order of magnitude for a badly clogged filter, not a prediction for your house, and it was never measured against Ontario electricity prices or an Ontario summer.

What MERV rating should I put in my system?

The EPA says at least MERV 13 if you are upgrading, or as high as your system fan and filter slot can accommodate, and that second half is the important half. A filter denser than your blower was designed for restricts airflow and causes the problem you were trying to avoid. Check what your equipment supports before you buy, and if you want serious filtration, ask about a thicker filter in a media cabinet rather than a denser one in a 1 inch slot.

Do dirty air filters damage the air conditioner itself, or just waste energy?

Both. ENERGY STAR notes a clean filter prevents dust and dirt building up inside the system, which is what leads to expensive maintenance and early failure. Once dust bypasses a loaded filter it settles on the evaporator coil and insulates it, and the blower and compressor run longer and hotter against the restriction. The energy waste is the cheap part of the bill.

When the temperature climbs in Ontario, so does the hydro bill, and cooling can account for a large share of a home's summer electricity use. The good news is that a big chunk of that cost comes from small inefficiencies you can fix. With a few smart thermostat habits, some no-cost adjustments around the house, and the right equipment where it counts, you can stay comfortable all summer without dreading the bill. Here is how to keep your cooling costs under control.

Start With Your Thermostat

Your thermostat is the single biggest lever on your cooling bill. A few simple settings make a real difference:

• Set it as high as is comfortable. Natural Resources Canada suggests around 25°C when you are home and 28°C when you are out or asleep. Every degree warmer can trim cooling costs by roughly 3 to 5 percent.
• Do not overcool. Setting the thermostat colder than usual does not cool your home any faster. It just runs the system longer and wastes energy.
• Let it back off when you are away. Nudging the temperature up a few degrees while the house is empty adds up over a summer, with no comfort lost.
• Use a programmable or smart thermostat. It makes those adjustments automatically, learning your schedule so you save without thinking about it. Many Ontario rebate programs help offset the cost of a smart thermostat.

Free Habits That Lower the Bill

A cooler home is cheaper to cool. These cost little or nothing and the savings show up the same month:

• Close blinds and curtains on the sunny side of the house during the day, so the sun is not fighting your AC.
• Use fans to feel cooler. A ceiling or box fan uses far less power than an air conditioner and lets you raise the thermostat a couple of degrees. Fans cool people, not rooms, so switch them off when you leave.
• Cook and dry outside the heat of the day. Run the oven, stove and dryer in the early morning or evening, or grill outdoors, so you are not heating the house and cooling it at the same time.
• Seal the leaks. Weatherstrip drafty doors and windows so the cool air you paid for stays inside.
• Shade the outdoor unit. An air conditioner in shade runs more efficiently than one baking in direct sun.

Work With Time-of-Use Rates

If you are on a time-of-use or ultra-low overnight rate plan, when you cool matters as much as how much. Electricity costs less during off-peak hours, so a little planning goes a long way:

• Pre-cool your home before the afternoon on-peak period hits, then let the thermostat ease up during the most expensive hours.
• Run the AC harder overnight and early morning when rates are lower, and coast through the pricey mid-day stretch.
• Check that your rate plan fits your habits. The right plan for your household can shave money off every summer bill.

Where Bigger Savings Come From

The issue	What helps
An aging, single-speed AC	Modern variable-speed systems scale their output down to match small cooling needs, using far less power than an old unit running at full blast.
A neglected system	Regular maintenance and a clean filter keep the AC running efficiently. A dirty, strained system uses more energy for less cooling.
The wrong size for the home	An air conditioner sized correctly to your home cools evenly and efficiently, instead of short cycling or running non-stop.
Available rebates	Ontario programs such as Save on Energy offer rebates on efficient cooling upgrades and smart thermostats. Amounts change, so confirm current details before you buy.

Humidity plays a big role in summer comfort and cost too. For more on that, see our guide on how humidity affects your air conditioner's performance.

Upgrade for Long-Term Savings

Habits and settings go a long way, but if your air conditioner is old, undersized or running constantly, the biggest savings come from the equipment itself. A modern variable-speed system, or a heat pump that cools efficiently in summer and heats in winter, can meaningfully lower what you spend to stay comfortable. Aire One helps homeowners choose and size the right system, and points you to the rebates you qualify for.

An efficient, right-sized system is the surest way to lower cooling costs for years.

The goal is simple: a home that stays comfortable through the hottest Ontario days, cooling that runs efficiently instead of endlessly, and a summer hydro bill that no longer catches you off guard.

Complete Home Comfort From One Team

Lowering your cooling costs is part of whole-home comfort, and Aire One handles all of it from our Markham headquarters: air conditioners and ductless systems, heat pumps, smart thermostats and indoor air quality equipment, plus furnaces and central heating for the winter, and maintenance plans to keep everything running efficiently. That means one team to size, install and service the system that keeps you comfortable year-round.

We serve Markham and the surrounding communities, including Richmond Hill, Thornhill, Vaughan, Scarborough, North York and Toronto.

Frequently Asked Questions

What temperature should I set my AC to in summer to save money?

Natural Resources Canada suggests around 25°C when you are home and 28°C when you are away or asleep. Every degree warmer can cut cooling costs by roughly 3 to 5 percent, and a smart thermostat can make those changes automatically.

Does turning the thermostat way down cool my home faster?

No. Your air conditioner cools at the same rate regardless of the setting, so a colder setting just makes it run longer and use more energy. Set it to a comfortable temperature and let it work.

Do fans actually lower cooling costs?

Yes, indirectly. Fans use far less electricity than an air conditioner and help you feel cooler, so you can raise the thermostat a few degrees. Because fans cool people and not rooms, turn them off when you leave.

Are there rebates for a more efficient AC in Ontario?

Yes. Ontario programs such as Save on Energy offer rebates on efficient cooling upgrades and smart thermostats. Amounts and eligibility change, so confirm current details before you buy. Aire One can help you find what applies.

1. Change the Air Filter

Replacing the filter ensures that your air conditioner operates at peak efficiency. Make sure you change it in the fall or winter before turning off the unit entirely. Changing the filter on your unit is necessary to remove the dust preventing it from operating efficiently.

2. Clean the condenser coils

It’s the ideal time to inspect the condenser coils, which can become dirty and congested with debris after prolonged use. The exterior HVAC unit fins should also be vacuumed or cleaned of any debris. Inspect the fins to determine any potential damage and adjust them if required. Your unit runs more effectively when the coils are clean. Clogged coils may contribute to your unit’s inability to maintain the ideal temperature in your home.

3. Visually inspect your unit

It would be best if you did not allow the summer to end without investigating any strange sounds or smells you may have noticed. You should check the wiring for issues such as frayed connections caused by animals and insects inside the unit. Check for any damaged components, and have them repaired immediately.

4. Clean up the system’s surrounding

Clean up the area around the unit to optimize the performance of your unit. Its operation may be hampered by too much obstruction, which could lead to an early system failure.

5. Schedule a Professional HVAC Maintenance Checkup

You might as well have an HVAC technician from Aire One Heating and Cooling operating in Toronto & GTA checkup your air conditioner thoroughly in addition to giving it a visual check yourself. A skilled technician can perform a wide range of preventative maintenance tasks to guarantee that your air conditioner runs as effectively and efficiently as possible.

How to Maximize Your AC Maintenance Routine

Follow the suggestions above to keep your unit running smoothly throughout the year. If your unit hasn’t been inspected, that’s a really bad situation. If you had maintenance performed relatively early in the year, before summer ends are the ideal time to have it done again. Contact Aire One Heating and Cooling to check your AC unit professionally.

Why Should You Clean Your Ac?

To Improve Airflow

The airflow of your AC unit becomes restricted when it is covered in dust and dirt. This can cause your AC to work harder to cool your home, leading to higher energy bills. Cleaning your AC will help improve airflow and increase its efficiency.

To Prevent Allergies

If you or someone in your family suffers from allergies, dust and dirt can worsen them. By cleaning your AC unit, you can help reduce the dust and dirt in your home, making it easier to breathe.

To Prolong the Life of Your AC Unit

When an AC unit is covered in dust and dirt, it has to work harder to cool your home. This can cause the unit to overheat and break down. Cleaning your AC unit can help it run more efficiently and prevent it from breaking down prematurely.

How to Clean Your AC’s Exterior Condenser Unit

The first step to cleaning your AC unit is to clean the exterior condenser unit. This large, box-like unit is usually located outside your home. To start with, turn off the power to your AC unit at the breaker box. This is important for safety reasons.

Next, use a garden hose to spray down the entire unit. You should also remove any leaves or other debris accumulated around the unit. Once you’ve sprayed down the unit, use a brush to scrub away any stubborn dirt or grime. If there is a lot of dirt and grime, you may need a putty knife or another tool to scrape it off.

Finally, rinse the unit with your garden hose and allow it to air dry.

How to Clean Your AC’s Interior Components

Once you’ve cleaned the exterior condenser unit, you can move on to cleaning the interior components. To start, remove the panels from your AC unit. These are usually located on the sides of the unit. Once you’ve removed the panels, you should be able to see the evaporator coils.

Use a brush to clean the evaporator coils. If they are particularly dirty, you may need a coil cleaning solution. Once you’ve cleaned the coils, replace the panels and turn on the power to your AC unit.

Since cleaning an AC unit requires turning off the power to the unit and other potentially dangerous steps, it’s best to leave it to a professional. A trustworthy HVAC company like Aire One Heating & Cooling will be able to clean your AC unit quickly and efficiently, so you can enjoy a cool, comfortable home all summer long.

What Happens If Your System Has Static Pressure Problems?

Excessive Static Pressure:
High static pressure can decrease the airflow in your system. In addition, the resistance increases, which can cause foul odors to linger, mold and mildew in your ductwork or fan coil units or dirty coils, or cause damage to the refrigerant lines. More importantly, if you don’t take care of this problem, it will cost you more money in the long run.

Low Static Pressure:
Suppose your system has low static pressure, then there is a greater chance for moisture on condensation problems, which could result in safety hazards and increased energy costs due to inefficient equipment operation. If a system has too low of static pressure, airflow will not be able to move through the design into your conditioned space, and a backdraft can occur, which can cause damage. It can result in high energy bills, inefficient operation of equipment, and safety hazards.

What Is a Good Static Pressure in HVAC?
Usually, a recommended minimum static pressure for residential equipment is 6 inches of water column (IWC), which translates to a measured pressure of 0.09 inches of water gage.
High static pressure in your system is probably caused by an ill-fitted filter, a dirty coil, or other parts inside your unit like the blower wheel. Aire One Heating & Cooling, servicing the Ontario region would recommend cleaning your ring and replacing the filter. If you have low static pressure, it is probably caused by a problem with your ductwork or vents.

Static pressure problems in your heating and cooling can be easily solved if you take the time to investigate and fix them once it has been found. And remember, for a simple check of static pressure – You only need to know the basics. The best way to determine current static is to use a combination of two methods. First, you must measure the tubing pressure before loading the unit with any dirty laundry. Then calculate the difference between that and what was measured after loading the team with dirty laundry. You can also contact experts from Aire One Heating and Cooling in Toronto for assistance. Our licensed technicians will help you check your HVAC system and find the problem. Contact us today.

What is a Capacitor?

A capacitor is a device that stores an electric charge like a short-term battery. It is made of two metal plates, each having a positive and negative charge. When the electric current from one plate to the other passes through the capacitor, it creates an electric field between them that builds up energy until it is discharged.

Effects of a Bad Capacitor

Bad capacitors are one of the common issues with air conditioning systems. A bad capacitor prevents the exterior unit from properly functioning, which hinders the cooling process as a whole.  A bad capacitor can result from various factors, including age, excess power, etc. When this happens, the capacitor can’t store electrical charge, leading to poor performance from your air conditioning unit.

Clicking noise is one sign that your capacitor might have problems. Diagnosing the issue by yourself might lead to electrical shock. If you do not have an experience in wiring repairs and diagnosis, it is best to call a professional AC contractor like Aire One Heating and Cooling servicing Toronto & GTA as soon as possible.

If the capacitor is defective, it might cause the motor to stop working. That is because your system’s motor revolves around a capacitor. As a result, you may experience a humming sound and can eventually burn out. If you notice this issue, call a reputable HVAC technician from Aire One to diagnose the problem.

Hard starting of your air conditioner is another effect of a bad capacitor. That is because the AC compressor is usually connected to the capacitors, and turning it on might be an issue if they can hold no charge. At Aire One Heating & Cooling, we have all the tools necessary to diagnose and repair all your heating and cooling systems.

Your AC might not be able to produce enough cooling or heating at your home. That is because a capacitor is responsible for supplying the air conditioning system with electric power. This can result in poor performance of your whole home air conditioning system.

Repairing a Bad Capacitor

Most of the time, our experts will swap out the capacitors that are threatening the air conditioner’s capacity to operate properly. Never try to replace the capacitor yourself, please! If you are not trained on how to handle it, the oil that leaks from damaged or broken capacitors can be quite dangerous to handle. Our experts at Aire One Heating and Cooling in Toronto & GTA will be at your place immediately to help you diagnose and fix the problem. Contact us now to schedule your maintenance visit.

Breakdown Prevention and Fewer Repair Costs
When you schedule an annual HVAC inspection, you reduce the chances of breakdowns or problems requiring expensive repairs. Service appointments range from $150 to $500 and could go even higher if you require any replacement parts. Yearly check-ups are often less than $100 and help to prevent problems from occurring.

Protect Your Warranty
When submitting a warranty repair claim, most manufacturers request documentation of yearly maintenance from a credible HVAC technician. Certain components of your HVAC system are costly so investing in a yearly maintenance schedule to keep it backed under warranty is a good decision.

Extend System Lifespan
Regular maintenance increases the lifespan of your system, lowering the possibility that you’ll have to spend a lot of money on HVAC installation anytime soon. It’s similar to how annual check-ups may help humans live longer; only your HVAC doctor comes to your house.

Protect Your Family
Regular maintenance prevents dust and other impurities from blocking your HVAC system. When you perform regular maintenance on your HVAC system, you protect your family from potentially dangerous impurities in your home’s air.

Increased Energy Efficiency
A well-functioning HVAC system, of course, implies cheaper utility expenses. If your system is clean and the parts are working properly, your HVAC system will not have to work as hard to cool the rooms in your house. Similarly, an expert HVAC technician can recalibrate your thermostat settings to guarantee optimal operation.

Maintain Optimum Comfort
You rely on your HVAC unit to keep your home comfortable all year. Maintaining your system annually allows it to create and distribute warm or cold air more uniformly and reliably. Regular maintenance from a licensed HVAC technician will also reduce the likelihood of HVAC sounds or odors interfering with your quality of life.

How Does The AC Cause Sickness?
The chilly air that air conditioners produce is not necessarily hazardous. When air conditioners, bacteria, allergens, fungi, mold, and mildew come together, they may cause sickness. Condensation is created as air is forced over the coils of an air conditioner. If the air conditioner is not cleaned regularly, the moisture from this condensation can provide an ideal breeding ground for germs and mold to develop.

Another cause of air conditioning sickness is running an air conditioner too cold. The cold air can cause your nasal passages to shrink, causing blockage and congestion of the sinuses or even the lungs. It is important to keep the temperature of an air conditioner to a comfortable level.

Importance of AC Maintenance
Routine AC maintenance is the easiest and least expensive way to prevent AC sickness. You must know your air conditioner’s maintenance needs and keep up with them regularly.

An air conditioner should be serviced at least once a year. This allows the technician to inspect the AC for mold, mildew, dirt, and dust. The technician will also clean the coils inside the unit and check for proper operation, corrosion and leaks. They will also make sure your unit is running at peak efficiency.

Air conditioners can be a breeding ground for bacteria, fungi, and mildew. Mold spores can grow on wall grills or dust particles in the air conditioner vents. If you notice mold growth in your vents, contact Aire One Heating & Cooling. While breathing in this kind of mold may not cause sickness immediately, prolonged exposure to it can lead to an irritated throat and lung infection.
