When the house won't cool down

An air conditioner that runs without cooling is usually telling you something specific, and the fix is often small — if it's caught early. A slow refrigerant leak that could have been a straightforward repair becomes a compressor replacement if the system runs that way all summer.

Signs your AC needs service

  • It runs, but the house never reaches the set temperature
  • Warm air from the vents while cooling is on
  • Weak airflow, or no airflow in part of the house
  • Ice on the indoor coil, the refrigerant lines or the outdoor unit
  • Grinding, squealing, rattling or banging from the condenser
  • Water pooling around the indoor unit
  • Short cycling, or power bills climbing versus last summer
  • Musty smells from the vents when cooling runs

Two things to check before we come out

If the system has frozen over, shut it off at the thermostat and leave the fan running to thaw it before we arrive. It makes the diagnosis faster and keeps the visit shorter.

What typically fails on an Alberta system

Capacitor

The most common summer failure by far. Capacitors give the compressor and fan the kick they need to start, and heat shortens their life. Symptom: a hum, no start, or the fan running while the compressor doesn't.

Contactor

The relay that sends power to the compressor. Pitted contacts cause intermittent operation — the system works, then doesn't, then works again.

Refrigerant leak

Low refrigerant isn't something a system "uses up" — it means there's a leak. Topping it up without finding the leak is throwing money away, so we locate it and give you the options honestly.

Frozen evaporator coil

Caused by restricted airflow or low refrigerant. The ice is a symptom; the cause is what needs fixing.

Condenser fan motor

The outdoor fan keeps the compressor from overheating. When it fails on a 30 °C day, the system shuts down on a high-pressure safety — which is exactly what should happen.

Condensate drain

A clogged drain line backs water up into the pan and onto the floor. Preventable with an annual cleaning, and cheaper than the drywall repair.

Repair or replace

A central AC in Alberta typically lasts 15 to 20 years. Under 10 years, repair almost always wins. Over 15 with a compressor or coil failure, the repair often approaches the cost of a new system — and a new Lennox unit comes with a 10-year limited parts and labour warranty, conditions applicable. Our prices are posted, so the comparison is easy to make.

A note on refrigerant

If your system is older and runs R-22, parts and refrigerant are expensive and getting harder to source, which usually tips the decision toward replacement. Newer equipment uses different refrigerants, and manufacturers have been transitioning to lower-GWP options — we'll tell you exactly what your system uses and what the new one would use.

What happens on an AC service call

Prevent the next breakdown

An annual spring tune-up catches a weak capacitor, a dirty condenser coil or a slow leak before the first heat wave. It's part of the VIP Program, with unlimited service calls and 15% off repairs for $275 a year.

Good questions

Frequently asked questions

Why is my AC running but not cooling?

The usual suspects are a failed capacitor, low refrigerant from a leak, a frozen or dirty evaporator coil, or a failed contactor. A proper diagnostic identifies which one before anything gets replaced.

There's ice on my air conditioner. What do I do?

Turn the system off and let it thaw, and check the air filter. Ice means restricted airflow or low refrigerant. Running a frozen system can damage the compressor, so shut it down and call us.

How much is an AC service call?

$195 plus GST for the diagnostic, with a written estimate before any repair begins. VIP members get unlimited service calls and 15% off repairs.

Should I repair or replace a 14-year-old air conditioner?

For a small repair like a capacitor or contactor, repairing usually makes sense. For a compressor or evaporator coil, the cost often approaches a new system — we'll show you both numbers before you decide.

Do you service all AC brands?

Yes, all major residential brands. We specialize in Lennox as an Authorized Dealer.

Why does my AC smell musty?

Usually moisture sitting on the evaporator coil or in the drain pan, sometimes a clogged condensate line. It's worth cleaning properly — that smell is circulating through the whole house.

My breaker trips when the AC starts. What does that mean?

Often a failing capacitor or a compressor drawing too much current. Don't keep resetting it — repeated trips can damage the compressor and the breaker is warning you for a reason.
