FAQ’s & answers to avoid a service charge!

Common Central Air Conditioning questions & answers to avoid a service charge!

What temperature should I set my AC to?

21 Degree’s is the recommended manufacture’s setting. You can go lower at your own risk of freezing up the
system which will take 12 hours to thaw. This doesn’t hurt the system, but it is a nuisance.

See our full article here.

Is it normal for my new AC to run a lot?

When outside temperatures reach the high +20’s to mid +30’s Yes, it is completely normal. Most systems will also struggle to keep up depending on several factors: type of insulation in your home, type of windows, how powerful the original furnace & ducting that was designed when the home was built.

NOTE: most homes aren’t necessarily designed for AC, and there is no way for us to know as all the ducting is covered behind drywall, typically unfortunately its commonly too small for cooling.

When should I turn on my AC during the day?

You should be setting your desired temperature and leaving it alone. If you wait till the house is too hot the average
system will take up to 12 hours to bring the heat down even 3-4 degrees. Set it & leave it alone for the most efficient use of your AC system.

Why is my AC not turning on?

This could be a few reasons. The outside temperature needs to be +15 min for the system to start up. Check to make sure the breaker on? Is the indoor temp set lower than the ambient room temperature?

I need to refill my system cause it’s low on refrigerant.

This means your system is leaking and needs to be repaired. It is illegal to refill a leaking system and fines are up to $50,000 to the company and $5,000 to the homeowner. A leak repair is mandatory before refilling as per Calgary bylaw regulations.

My AC doesn’t blow enough air to certain rooms.

That’s because the AC system doesn’t move any air, the blower motor inside your furnace does this. Air flow around the home will be the same as it originally was before the AC was installed. The AC only cools the air.

My AC has ice build up and looks frozen.

Check your furnace filter and make sure all vents/ registers around the home are not blocked or closed. Lack of air flow through your furnace will cause the ac coil to freeze due to the cold temperature.

My AC isn’t cooling my home enough?

Make sure your blinds are closed to avoid direct sunlight into the home as this is additional heat load on the AC system
which will make it struggle especially at +30. Check and close all basement vents/ registers to force the cool air up to the warmer floors. Direct sunlight on your thermostat will also cause issues and confuse the system. Make sure you keep
outside doors & windows closed to avoid extra stress on the AC system.
