If your air conditioner runs for a minute or two, quits, then fires back up again, you’re not imagining it. I’ve been on a lot of Calgary service calls where the homeowner says, “It’s cooling… kind of… but it just won’t stay running.” Half the time the house feels clammy, the other half the time the unit outside sounds like it’s getting whiplash. This stop-start pattern isn’t just annoying. It can chew through parts faster than you’d think, and it usually bumps your power bill up while doing a worse job at comfort. (more…)

I’ve been on a lot of summer calls in Calgary where the AC looks fine outside, the furnace fan can run, but the wall control just sits there like it’s on a coffee break. Screen blank, buttons laggy, set temperature changes and nothing happens. Usually it’s something small. Sometimes it’s a chain of small things, and that’s the annoying part because you can waste an hour chasing the wrong clue. (more…)

I’ve been in a lot of Calgary basements where the old air conditioner is still chugging along, loud as a lawnmower and cooling like it’s trying its best. Then the first hot week hits, it quits, and suddenly you’re staring at brochures full of numbers. One of those numbers matters more than people expect: the SEER number. It’s basically a yardstick for seasonal energy use, but real life isn’t a lab, and your house isn’t a test bench either. (more…)

I get this call every summer in Calgary. You peek inside the mechanical room or pop the outdoor panel and you see white ice where there should only be cold metal and a bit of sweat. It looks weird because it is. Most of the time it is not “too much cold”, it is not enough heat getting across the coil. Low airflow, low refrigerant charge, dirty filter, blocked return, a fan that is tired. I have seen people keep running it anyway because “it’s still cooling a bit.” That’s how a small issue turns into a long afternoon and…

I’m Chris, I’ve been fixing and installing comfort systems in Calgary for about 15 years, and one of the most common complaints I hear is “the unit runs, but the house still feels stuffy.” Usually the equipment is not “broken” in a dramatic way. It’s small, boring stuff that chokes the ducts or starves the return air. Half the time I walk downstairs and see the filter jammed in backwards, or a return grille buried behind a couch. You’d be surprised what a single blocked grille can do to the bedrooms down the hall, well, usually anyway. If you’re shopping…

I get this one a lot in Calgary. You flip on your home cooling, you keep it set where you can actually sleep, and then your power charges show up and it feels like something is broken. Sometimes something is broken. Other times it is just how hard your system has to work in our dry heat, especially if your place bakes in late-day sun and the air leaks out faster than you think.

I’m Chris, senior tech at Calgary Air Heating and Cooling Ltd here in Calgary, and I’ve been fixing residential cooling systems around Alberta for about 15 years now. A lot of service calls I walk into aren’t “broken unit” calls, not really. The system runs, it cools, but the power bill feels rude, the house gets clammy, and the thermostat becomes a daily argument. Most of the time, it’s not one magical setting. It’s a handful of small habits and a couple of basic maintenance items that people ignore because they’re boring. (more…)

I’m Chris, I’ve been fixing and installing air conditioners in Calgary for 15 years, and I can tell you this: the heat exchanger gets all the attention in winter, but in summer the A-coil and the outdoor condenser are where comfort gets won or lost. You can have a decent system and still end up with weak airflow, longer run times, and that sticky house feeling because the heat just can’t move like it’s supposed to. (more…)

I’m Chris, senior HVAC tech at Calgary Air Heating and Cooling Ltd here in Calgary, and I’ve lost track of how many calls begin with the same sentence: “The air conditioner is running, but the air coming out has this… funk.” Sometimes it’s that damp basement kind of odour. Sometimes it’s a hot, dusty, almost electrical scent that makes you shut the unit off and stand there listening to see if something is about to go sideways. And sometimes it’s a sharp, tangy note that hits you right at the register like something spilled and never got cleaned up. (more…)

  The only safe approach is to link the heating unit to a backup power source through a proper transfer switch. Skipping this step risks backfeeding electricity into utility lines, which is dangerous for technicians and neighbours. A licensed electrician can install this switch and verify that the wiring supports the extra load without tripping breakers. (more…)
