We've seen every issue a neglected or aging cooling system can develop. Here are the problems homeowners call us about most often.

❄️

AC Running But Not Cooling Effectively

This is most often caused by dirty evaporator or condenser coils that can no longer transfer heat efficiently, reducing the system's ability to reach the set temperature. Left unaddressed, the compressor works harder than it should and wears out significantly faster than a well-maintained unit. We clean both coil surfaces and test airflow and refrigerant pressure as part of every maintenance visit.

High Electricity Bills During Cooling Season

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.

🔊

Strange Rattling or Buzzing From the Unit

Rattling, buzzing, or grinding sounds usually point to loose fasteners, a worn capacitor, 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.

💧

Water Leaking Around the Indoor Unit

Water pooling near the air handler is almost always caused by a blocked condensate drain line that has filled the drain pan until it overflows. Left uncleared, overflow can cause water damage to ceilings, walls, and flooring. We clear the condensate drain and flush the line during every maintenance visit and confirm drainage is flowing correctly before finishing the job.

🔩

AC Turning On and Off Too Frequently

Short cycling, where the system runs for only a few minutes before shutting off and restarting, commonly points to a dirty coil, refrigerant imbalance, or a failing capacitor that cannot sustain proper startup voltage. Frequent short cycles accelerate compressor wear and raise energy costs at the same time. We test for all three causes and address the source directly, not just the symptom.

🔧

AC Worked Last Summer But Won't Start Now

A system that sat through the off-season without maintenance can develop capacitor degradation, contactor corrosion, or blocked airflow that prevents it from starting 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.

🌬️

Musty Smell Coming From AC Vents

A musty or stale odour from the vents when the AC runs is usually caused by biological growth on the evaporator coil or in the drain pan, both of which stay damp during normal operation. This is especially common after a season with no maintenance. We clean the coil and drain assembly and eliminate the source of the odour during the maintenance visit.

💦

AC Cooling But House Still Feels Humid

An air conditioner that cools but leaves the home feeling muggy is often running with low refrigerant charge, causing the evaporator coil to operate at a temperature too warm to condense moisture effectively. A fouled coil can produce the same symptom. We check both refrigerant charge and coil condition during maintenance and correct whichever is affecting dehumidification.

🏠

One Room Much Warmer Than the Rest

When one room consistently stays warmer than others, the issue is usually a blocked or restricted duct run, a partially closed damper, or a dirty filter starving that branch of the system of airflow. Maintenance is the right time to check register balance and duct integrity across the full system. We test airflow at each register and adjust or clear whatever is causing the uneven distribution.

Reviews

What Our Customers Say

★★★★★

System reaches temperature so much faster now

We booked maintenance before summer started and the difference was noticeable within days. The house cools down in minutes instead of dragging on like before. Gas Services Edmonton explained exactly what they cleaned and adjusted.

★★★★★

Caught a refrigerant issue before it got worse

The technician found our refrigerant charge had drifted slightly low and corrected it on the spot. Said it would have kept getting worse and driving up our bills if we'd waited another year. Glad we finally scheduled this.

★★★★☆

Thorough visit, coil needed extra attention

Our coil hadn't been cleaned in a few years so the visit ran a bit longer than quoted. The technician explained why upfront and the system runs noticeably quieter now. Worth the extra time it took.

★★★★★

Written summary was actually useful

Gas Services Edmonton gave us a detailed report of everything checked and the readings taken during the visit. Nice to have real documentation instead of just being told everything looked fine.

★★★★★

Knew exactly what our heat pump needed

We have a heat pump and the technician clearly knew the additional components that needed checking beyond a standard AC. Explained the reversing valve check and everything else clearly. Appreciated the expertise.

★★★★★

Bills finally stopped creeping up

Our electricity bill had been climbing every summer for a few years and we couldn't figure out why. Turned out our system just needed proper maintenance. Gas Services Edmonton fixed that and our bills leveled out this season.
