Most air conditioner breakdowns start as small problems that go undetected without annual service. Here are the issues our technicians find most often during maintenance visits.

❄️

AC Not Cooling As Well As Before

Evaporator and condenser coils collect dust, pollen, and debris over each season, reducing heat transfer efficiency and forcing the compressor to run longer cycles. A system with heavily fouled coils can lose a significant portion of its cooling capacity without any obvious sign of failure. We clean both coils as part of every maintenance visit to restore efficient heat exchange.

AC Capacitor Starting To Fail

Capacitors assist the compressor and fan motors during startup, and they degrade gradually over time until they fail completely, usually at the worst possible moment during a heat wave. A capacitor reading outside its rated range will cause hard starts, slow fan spin, or an outright no-cooling situation. We test capacitor values during maintenance and replace declining units before they fail.

💧

Water Leaking From Indoor AC Unit

The condensate drain removes humidity extracted from indoor air, and algae, dust, and debris can block the line over a season of operation. A blocked drain causes water to back up into the drain pan, overflow onto the floor, or trigger a float switch that shuts the system down. We flush and inspect the drain line during every maintenance visit to prevent moisture damage.

🔍

AC Refrigerant Is Low

Refrigerant does not deplete normally, so a low reading always means there is a leak somewhere in the system. Running a system with low refrigerant stresses the compressor, reduces cooling output, and can cause the evaporator coil to ice over. We check refrigerant pressures during maintenance and investigate any variance before it causes serious compressor damage.

🔊

AC Making Rattling or Buzzing Noise

Rattling, buzzing, or grinding sounds usually point to loose fasteners, a worn contactor, or a motor that needs lubrication and cleaning. Ignoring these sounds allows the underlying problem to progress until a component fails completely, often mid-season. Our technicians inspect all moving parts, electrical components, and fasteners as part of the standard maintenance inspection.

🌬️

Weak Airflow From AC Vents

A clogged air filter, a collapsed flex duct, or blocked supply registers can restrict airflow enough to cause the evaporator coil to freeze, the system to short-cycle, or uneven cooling room to room. Homeowners often assume the AC is failing when the actual problem is airflow restriction upstream of the coil. We check filter condition, duct integrity, and register clearance during every service call.

🌡️

Thermostat Not Holding the Right Temperature

A thermostat that reads the room temperature incorrectly causes the system to cycle too early, run too long, or fail to reach the set temperature consistently. This is especially common in older thermostats or units placed near heat sources. We test thermostat accuracy and recalibrate or recommend replacement where the variance is affecting comfort.

🔧

AC Worked Last Year But Struggles Now

A system that sat through the off-season without maintenance can develop capacitor degradation, contactor corrosion, or blocked airflow that prevents it from running reliably. These are predictable failures that an annual pre-season maintenance visit is specifically designed to catch and resolve. We test all startup components and confirm safe operation before the cooling season begins.

📈

High Electricity Bills During Summer

An air conditioner operating with dirty coils, restricted airflow, or a low refrigerant charge uses substantially more electricity to produce the same cooling output as a maintained system. Even a modest efficiency drop adds up over a full summer of daily operation. Annual maintenance restores rated operating efficiency and typically produces a measurable reduction in cooling costs.

Reviews

What Our Customers Say

★★★★★

Caught a leak before it became a repair

The technician found our refrigerant was low and traced it to a small leak at a fitting before it turned into anything serious. Gas Services Edmonton fixed it on the spot and the system has run perfectly since. Glad they check the actual charge instead of just topping it up.

★★★★★

House feels noticeably less humid now

I didn't realize how much our coils had built up over the years until the cleaning was done. The house feels drier and cools faster than it has in a long time. Worth every dollar for the difference it made.

★★★★☆

Thorough visit, took a bit longer than quoted

Our system needed a bit more attention than the standard 90 minutes because of a dirty condensate line, so the visit ran a little long. The Gas Services Edmonton technician explained why and didn't charge extra. Everything has run smoothly since.

★★★★★

Gave us documentation for our warranty

We had no idea our manufacturer required proof of maintenance until Gas Services Edmonton mentioned it and handed us a written record of the visit. That paperwork actually saved us when a part needed replacing under warranty a few months later.

★★★★★

No upselling, just an honest checkup

I expected a pitch for a full replacement given how old our unit is, but the technician just did the checklist and told us the system was still in good shape. Appreciated the honesty instead of a sales pitch.

★★★★★

Fixed a noisy capacitor before it failed

The tech noticed our capacitor was starting to weaken during the electrical check and swapped it out right then. A week later we had a heat wave and the system handled it without a hitch. Ridiculously good timing on that catch.
