Emergency HVAC in Richmond Hill
Furnace, boiler, heat pump or AC down? A system-by-system guide to what is urgent, what to do first and how to keep your family safe until help arrives.
The short answer: Call for emergency HVAC in Richmond Hill when your home has no heat in freezing weather, no cooling in a heat warning, a leaking boiler or furnace, a burning smell, or a heat pump that stays solid with ice. If you smell gas or a carbon monoxide alarm goes off, get everyone outside first and call Enbridge Gas or 911. Aire One answers 24/7 at 310-HEAT, and the service call starts at $79 with the repair price confirmed in writing before work begins.
Richmond Hill homes run on a wider mix of equipment than most people expect. Newer townhomes in the north end often use heat pumps or compact furnaces, family homes from the 1980s and 1990s rely on gas furnaces, and many older houses still heat with hot water boilers and radiators. Each system fails in its own way, which is why good advice on emergency HVAC in Richmond Hill starts with knowing what you have in the basement or beside the house.
Use the guide below to decide how urgent your problem is, what to do in the first ten minutes, and how to keep everyone safe and comfortable while a technician is on the way. If your system is down right now, call 310-HEAT (310-4328) or book an emergency visit online.
Key takeaways
- Gas smells and carbon monoxide alarms come first: leave the home, then call for help from outside.
- Frost on a heat pump is normal during defrost; a unit that stays solid with ice is not.
- A boiler that is leaking or showing very high pressure should be shut off and checked the same day.
- Use space heaters only with care: keep them clear of anything that can burn and never leave them running unattended.
- Maintenance plan members get priority booking when demand for emergency service spikes.

The First 10 Minutes: A Step-by-Step Plan
Before you call for emergency HVAC in Richmond Hill, work through these steps in order. The first one is about safety; the rest often solve the problem outright.
- Check for danger. If you smell gas, leave the home without touching switches or using a phone inside, then call the Enbridge Gas emergency line at 1-866-763-5427 or 911. If a CO alarm sounds, get everyone and pets outside and call 911.
- Look at the thermostat. Make sure it is on Heat (or Cool), the set point is correct, and the screen is not blank from dead batteries.
- Check power. Look for a tripped breaker and confirm the service switch beside the furnace or air handler is on.
- Check the filter. A packed filter can trigger a high-limit shutdown. Swap it if it is clogged.
- Check outside. Clear snow from furnace intake and exhaust pipes and from around the heat pump.
- Stop water damage. If the system is leaking, turn it off, move valuables and put down towels or a pan.
- Call and describe what you see. When you call for emergency HVAC in Richmond Hill, note any error lights, sounds or smells. It helps the technician arrive with the right parts.
Heat Pump Iced Over: Normal or an Emergency?
More Richmond Hill homes now heat with cold-climate heat pumps, and the most common worried call we get is about ice. A thin layer of frost on the outdoor coil is normal in winter. The unit runs a defrost cycle that melts it, sometimes with a whoosh of steam, and then goes back to heating.
It becomes a call for emergency HVAC in Richmond Hill when:
- The whole unit is encased in ice and stays that way for hours.
- The fan is blocked by ice or snow and cannot turn.
- The home is getting cold and the backup heat is not keeping up.
- Water from the roof or eavestrough is dripping straight onto the unit and refreezing.
Do not chip ice off with a shovel or pour boiling water on the coil, as both can damage the fins and refrigerant lines. Turn the system to emergency or auxiliary heat if your thermostat has that setting, clear loose snow around the base, and call. Our guide to heat pump installation in Richmond Hill explains how proper placement and stands prevent most icing problems.
Boiler and Radiator Emergencies in Older Richmond Hill Homes
Many older homes around the Mill Pond area and Richvale still heat with hot water boilers. They are durable and comfortable, but they need a technician who understands hydronic systems. Treat these signs as urgent:
- Water on the floor around the boiler, which can come from a failed pump seal, fitting or the boiler itself.
- The pressure-relief valve dripping or discharging, a sign that pressure is too high.
- Banging or kettling noises together with rising pressure.
- No heat to any radiator even though the boiler seems to run.
Turn the boiler off at its switch and call for emergency HVAC in Richmond Hill. Do not try to tighten valves or drain the system yourself. If only one or two radiators are cool and the rest are fine, bleeding trapped air is often enough, and that can wait for a regular visit.

Keeping Your Family Safe While You Wait
Most emergency HVAC in Richmond Hill visits are resolved in a single trip, but these steps keep everyone safe and comfortable in the meantime:
- Gather everyone in one room on the warm side of the house, close curtains and use blankets and layers.
- Use electric space heaters carefully. Plug them straight into the wall, keep them well away from bedding and curtains, and turn them off when you leave the room or go to sleep.
- Never heat with a gas oven, barbecue or outdoor heater indoors. They can produce deadly carbon monoxide.
- Protect pipes by opening cabinet doors on exterior walls and letting taps drip slowly.
- Check on vulnerable people. Seniors, infants and anyone who is ill feel the cold and heat first. In summer, Health Canada advises moving to a cool place during extreme heat.

Frequently Asked Questions
Is there 24/7 emergency HVAC in Richmond Hill?
Yes. Aire One answers calls 24 hours a day, 365 days a year across Richmond Hill and York Region, including nights, weekends and holidays. Call 310-HEAT (310-4328) or book online, and a technician will be dispatched based on the urgency of the problem.
Why is my heat pump covered in ice?
Light frost is normal in winter, and the heat pump clears it with a defrost cycle. If the whole unit stays encased in ice, the fan is blocked, or the house is getting cold, the defrost system or airflow may have failed. Switch to emergency heat if available and call a technician.
What should I do if my boiler is leaking?
Turn the boiler off at its switch, contain the water with towels or a pan, and call for service. Do not try to tighten fittings or drain the system yourself. A leak or a discharging relief valve can mean the pressure is too high and should be checked the same day.
Is it safe to use a space heater while my furnace is broken?
An electric space heater can be used safely if it is plugged directly into a wall outlet, kept well away from anything that can burn, and turned off when no one is in the room. Never use a gas oven, barbecue or outdoor heater to warm the house.
How fast can a technician arrive in Richmond Hill?
Arrival time depends on weather and call volume, but safety and no-heat calls in freezing weather are always prioritized. Maintenance plan members receive priority booking. When you call, we give you an honest time window rather than a guess.
