HVAC Services in Markham
A year-round planner: which heating, cooling and air quality services your home needs, how often, and the signs it is time to call.
The short answer: HVAC services in Markham cover everything that heats, cools and ventilates your home: furnace and boiler service, air conditioning, heat pumps, ductless systems, indoor air quality, water heaters and maintenance plans. Most homes need a heating tune-up every fall, a cooling tune-up every spring, a filter change every one to three months, and a replacement plan once major equipment passes about 15 years. Planning around the calendar costs less than waiting for a breakdown.
Your heating and cooling system is the biggest energy user in your home, and in Markham it works hard in both directions: through January cold snaps and humid July heat. Most homeowners only think about HVAC services in Markham when something stops working. This guide flips that around. It lists each service, what it actually includes, how often you need it, and the signs that tell you it is time to book, so you can plan ahead instead of reacting.
If you already know what you need, you can book a service visit online or see the full list of what we do on our HVAC company in Markham page.
Key takeaways
- Book heating service in fall and cooling service in spring, before demand peaks.

- Furnaces and air conditioners often reach the end of their service life around 15 to 20 years.
- Heat pumps and ductless systems can cut gas use and may qualify for provincial rebates.
- A maintenance plan bundles yearly visits and gives you priority booking in an emergency.

A 12-Month Calendar for HVAC Services in Markham
Markham's climate makes timing HVAC services in Markham simple: heat from roughly October to April, cooling from late May to September. Schedule around it and you avoid the busiest weeks of the year.
| Months | What to book or do |
|---|---|
| January to February | Check filters monthly, keep vents and outdoor units clear of snow, set humidifier for dry air |
| March to April | Get quotes for any replacement, check rebate eligibility, book spring AC or heat pump tune-up |
| May to June | AC tune-up before the first heat wave, turn off humidifier, swap to a fresh filter |

8 Signs Your System Needs Service Now
You do not have to wait for the calendar. Book HVAC services in Markham sooner if you notice any of these:
- Rooms that are noticeably colder or warmer than the rest of the house.
- Energy bills climbing without a change in how you use the system.
- Short cycling, where the system turns on and off every few minutes.
- New noises such as squealing, banging, rattling or grinding.
- A yellow or flickering burner flame instead of a steady blue one.
- Water around the furnace, air handler or outdoor unit.
- More dust, dry skin and static in winter, or a clammy feeling in summer.
- An air conditioner that runs constantly but never reaches the set temperature.
Anything involving a gas smell, a carbon monoxide alarm or a total loss of heat in freezing weather is an emergency. See our guide to emergency HVAC in Markham for what to do first.
How Long HVAC Equipment Lasts
Knowing roughly where your equipment is in its life helps you decide between another repair and a planned replacement, and helps you budget for HVAC services in Markham over the next few years. These are typical ranges for well-maintained equipment; your results depend on installation quality, usage and upkeep.
| Equipment | Typical service life | Plan ahead when |
|---|---|---|
| Gas furnace | 15 to 20 years | Over 15 years with repeat repairs |
| Central air conditioner | 12 to 15 years | Uses older refrigerant or needs a major part |
| Heat pump | 12 to 15 years | Falling efficiency in cold weather |
| Boiler | 20 years or more | Leaks, corrosion or rising fuel use |
| Tank water heater | 10 to 12 years | Rust-coloured water or moisture at the base |
If your furnace is in the replacement window, start with a planned visit rather than waiting for a breakdown; our furnace installation in Markham page explains options, financing and the 10-year worry-free warranty.
Upgrades Worth Considering
When it is time to replace something, these upgrades are the ones homeowners ask about most when booking HVAC services in Markham:
- Cold-climate heat pumps. They heat and cool, can cut gas use when paired with a furnace, and qualifying models may be eligible for rebates through the Home Renovation Savings Program. See our guide to heat pump installation in Markham.
- Ductless mini-splits. Ideal for additions, finished basements, sunrooms and older homes without ductwork.
- Smart thermostats. Simple scheduling and remote control that reduce run time without sacrificing comfort.
- HRVs and humidifiers. Fresh air and balanced humidity for tightly sealed modern homes during long winters.
- High-efficiency furnaces. Up to 98.5% AFUE, meaning almost all the fuel you pay for becomes heat in your home.
How to Choose a Provider for HVAC Services in Markham
The right provider should be able to handle every service above, not just one. Look for:
- TSSA registration for any gas work, and certified technicians on staff.
- Experience across systems: furnaces, boilers, air conditioners, heat pumps and ductless.
- Written pricing before work begins, and written warranties on parts and labour.
- True 24/7 availability for heating and cooling emergencies.
- A maintenance plan that bundles yearly visits and gives you priority booking.

Frequently Asked Questions
What HVAC services do Markham homes need each year?
Most Markham homes need a furnace or boiler tune-up every fall, an air conditioner or heat pump tune-up every spring, and a filter change every one to three months. Homes with humidifiers, HRVs or water heaters should have those checked once a year as well.
How often should I replace my furnace filter?
Check it monthly and replace a standard one-inch filter every one to three months. Homes with pets, allergies or renovations may need more frequent changes. Thicker media filters usually last longer; follow the manufacturer's guidance.
Is it worth getting a maintenance plan?
For most homeowners, yes. A plan bundles your fall and spring tune-ups, helps keep manufacturer warranties valid, and gives you priority booking during cold snaps and heat waves when demand is highest.
When should I replace my furnace instead of repairing it?
Consider replacement when the furnace is around 15 years or older, needs frequent repairs, or a single repair would cost close to half the price of a new unit. A cracked heat exchanger means replacement, because the furnace is no longer safe to run.
Does Aire One service all brands in Markham?
Yes. Aire One is a Carrier Factory Authorized Dealer and services all major makes and models of furnaces, boilers, air conditioners, heat pumps and ductless systems across Markham and York Region, 24 hours a day.
