How it works

One system. Every season.

A real basement setup: a high-efficiency gas furnace, an AC coil on top, and an outdoor unit that's either an air conditioner or a heat pump. Pick a mode and watch it run.

🔥 Heating with the furnace

  1. Thermostat calls for heat. The draft inducer starts and pulls fresh outside air in through the PVC intake.
  2. Igniter lights the burners. Flames heat the primary heat exchanger. Combustion gases never mix with your air.
  3. Secondary heat exchanger squeezes out more. It cools the exhaust until water condenses. That's what makes it high-efficiency, and why there's a condensate drain and cool PVC exhaust.
  4. ECM blower moves the air. Return air passes through the filter, across both heat exchangers, and out the supply ducts to every room.

FAQ

Good questions.

How do I get a quote?

Call or text (226) 971-3593 or email dan@danairhvac.ca. Tell us what's going on and we'll set up a time to take a look. Quotes are free.

Do my furnace and AC really share parts?

Yes. With central air, the AC coil sits on top of the furnace and uses the furnace blower and ducts. That's why a furnace and AC are often planned together.

How often should my furnace be serviced?

Once a year is the usual recommendation, ideally before the heating season. A check-up catches small problems early and keeps the system running safely.

How often should I change my filter?

Check it every month or two and replace it when it looks grey or dusty. A clogged filter makes the blower work harder and cuts airflow to your rooms.

What brands do you work on?

All the major ones. We install and service Carrier, KeepRite, Goodman, York, Mainline, Lennox, Daikin, Rheem, Navien, Panasonic and many more. Tell us what you have and we'll take care of it.

Do you work on boilers?

Yes. We install, service and repair boilers for hot-water heating, as well as the gas piping that feeds them.

Furnace or heat pump: which is right for me?

A heat pump heats and cools with electricity, and many homes pair one with a gas furnace for the coldest days (dual fuel). We'll look at your home and walk you through the options on the free quote visit.

Can you run a gas line for my BBQ, range or fireplace?

Yes. Gas piping is one of our core services, including new lines for boilers, fireplaces, ranges, BBQs and water heaters. Our licensed gas technicians bring 18+ years of experience.

Why is my home so dry in winter?

Cold outdoor air holds little moisture, so heated indoor air feels dry. A whole-home humidifier on your furnace adds moisture back to every room.
