How Often Should You Service Your Air Conditioner in Calgary?

If you’ve been through even one Calgary summer, you know the drill. One week it’s patio weather, the next week you’re melting into your sofa and wondering why you ever wished for heat in the first place. That’s when your air conditioner suddenly turns into the MVP of your home.

The funny thing is, most of us never think about our AC until it quits. And when it quits, it’s usually at the worst possible time—like 3 in the afternoon on the hottest day of July. Cue the frantic phone calls and the unexpected repair bill. So let’s get ahead of the drama. How often should you really be servicing that big humming box outside?

Warning signs that your AC needs immediate servicing

• Reduced cooling efficiency.

• Strange noises or unusual odors.

• Higher than usual energy bills.

• Frequent cycling on and off.

• Lack of air flow throughout the vents

• Frost buildup on the copper lineset

• Never reaching target temperature

Why Servicing Is Actually Worth It

I get it. Nobody brags about booking their AC tune-up. You don’t throw a party to celebrate a clean filter. But here’s the truth: servicing makes a huge difference, and you notice it most when you skip it.

A dirty filter forces the system to use way more power than it should, which shows up right on your energy bill. Neglect it long enough, and you’re basically paying extra for hot air. On the other hand, a little bit of yearly TLC can stretch your system’s lifespan by years. I’ve seen air conditioners that are still kicking at 12 years old because their owners stayed on top of maintenance. I’ve also seen units give up at seven because they were ignored.

And here’s the big one: breakdowns always seem to happen at the worst time. A spring check-up means you’re not sweating through your shirt while waiting three days for a repair during a July heatwave. Think of it like brushing and flossing—boring, but way cheaper than fixing cavities later.

How Often Should You Service It?

The easy answer is once a year. But Calgary doesn’t always play nice, and sometimes once isn’t enough.

If your unit is fairly new and you only run it occasionally, a spring service before the first heatwave is usually fine. That gives a technician time to clean it out, test everything, and get it ready for heavy use.

But if your AC is older—or if you’re the type of household that blasts it day and night through July and August—then twice a year is smarter. A fall visit helps clear out the gunk from summer, checks refrigerant, and makes sure the unit can rest easy over winter.

And in between? A few simple DIY jobs go a long way. Change the filters, vacuum the vents, and make sure there’s no debris blocking the outdoor unit. Nothing fancy, but it helps your system breathe.

What Happens During an AC Service?

• Inspection of filters, coils, and fins.

• Cleaning and lubrication of moving parts.

• Checking refrigerant levels and thermostat calibration.

• Safety checks to prevent breakdowns.

• Electrical reading of parts

Why Calgary Makes It Tougher

Let’s be honest: Calgary is rough on ACs. Between dust storms, never-ending road construction, and wild weather swings, your system works harder here than it would in a milder climate. By July, many units are running 12 to 16 hours a day just to keep up. That kind of workout makes at least one yearly service non-negotiable, and for some homes, two services a year just makes sense.

When You Shouldn’t Wait

There are times when you shouldn’t put things off until spring. If your AC is blowing warm air, making strange noises, giving off odd smells, or causing your energy bill to suddenly spike, it’s waving a big red flag. Short cycling—when it keeps switching on and off—is another warning sign.

I once went to a home where the family ignored short cycling for weeks. By the time we showed up, the compressor had burned out completely. That repair cost thousands. A simple service would have caught the issue early and saved them a ton of stress.

What a Professional Service Actually Includes

If you’ve never booked a service before, you might picture someone just wiping it down and calling it a day. That’s not it. A proper tune-up covers a lot of ground.

Technicians will clean the coils, replace or wash the filters, lubricate the moving parts, check refrigerant, inspect electrical connections, calibrate the thermostat, and run safety checks. It’s basically a full health exam for your AC. Each step on its own doesn’t sound like much, but together they keep your system running smoothly when you need it most.

Why Pros Beat DIY Every Time

Sure, there are things you can handle yourself. Swapping filters? Easy. Clearing weeds around the outdoor unit? Simple. But catching a refrigerant leak or testing electrical parts isn’t something you can DIY with a screwdriver and YouTube.

Professionals bring trained eyes and the right tools. They’ll see problems you’d miss, clean things properly, and get it all done in a fraction of the time. What might eat up your whole Saturday usually takes them under two hours. It’s like cutting your own hair versus going to the barber. You can do it yourself, but you’ll probably regret it later.
