Before giving us a call, we encourage you to have a look at the following system checks to see if you can get things going again.

Air Conditioner/Heat Pump Repairs

1. Diagnostic Lights

The first thing you'll want to do is look for a small see-through spot in the furnace with lights in it. If it's blinking, write down how many times it blinks, and the colour (ex: 1 fast blink, then 3 slow blinks). Sometimes there's numbers written on a screen. Write those down.

3. Thermostat Batteries

Some thermostats have batteries that are responsible for turning things on and off at the right time. Change the batteries, regardless of what the battery indicator says. That being said; just because your thermostat screen is blank, it does NOT mean it's the source of the problem. Keep checking things on this list.

5. Bypass Damper is Closed

If applicable, make sure your humidifier damper is closed, or in the summer position.

2. Breaker and Switch

Make sure that your breakers are on for your heating system and air conditioner. Furnace switches can be hard to locate sometimes. They're usually high up at the bottom of the stairs or in the mechanical room. Sometimes it's good to switch the breakers and switch off and on again, even when it looks like it's in the on position.

4. Change the Filter

If a furnace overheats or if an air conditioner freezes up, it will do a little bit of work, but won't quite reach temperature. Replace your filter, turn it off for 3 hours, then turn it back on.

6. Air Conditioner Cover Removed

Make sure your winter cover is off for your air conditioner, if you have one.
