We've worked through every HVAC failure a home can develop. Here are the issues our clients call about most often, and how we approach each one.

🔥

Furnace Not Starting

A furnace that won't start is usually dealing with a failed igniter, a tripped safety switch, or a faulty control board. In older units with standing pilots, a thermocouple failure is a common cause. Running multiple restart attempts without resolving the underlying issue can overheat safety components and delay the correct diagnosis. We test the ignition system, control circuit, and safety devices in sequence to find the actual fault.

⚠️

Furnace Short-Cycling

Short-cycling means the furnace starts, runs for a short time, and shuts off repeatedly before the home reaches temperature. The cause may be a clogged filter restricting airflow, a failing pressure switch, a tripping high-limit switch, or a cracking heat exchanger triggering the safety shutoff. Each cause points to a different repair. We work through the diagnostic sequence to identify the specific fault before replacing any components.

❄️

Air Conditioner Not Cooling

An AC that runs continuously without lowering the indoor temperature is usually dealing with low refrigerant charge, a frozen evaporator coil, a failed capacitor, or a blocked condenser coil. Continuing to run the system in this state can damage the compressor over time. We test refrigerant pressure, inspect both coils, and check the electrical components to find the specific cause and repair it accurately.

🧊

Air Conditioner Freezing Up

A frozen AC evaporator coil is almost always caused by restricted airflow from a blocked filter or failing blower motor, or by low refrigerant charge reducing the pressure in the refrigerant circuit. Running the unit after it freezes risks overloading the compressor. We identify whether the freeze is an airflow problem or a refrigerant issue before recommending any work, since the repair is different for each cause.

🏠

Uneven Heating or Cooling Across Rooms

Rooms that are consistently hotter or colder than the rest of the home usually point to a duct issue, a zone valve problem in a multi-zone system, a refrigerant distribution imbalance, or an oversized or undersized unit for the space. Adjusting vents or changing thermostat settings rarely resolves the underlying cause. We assess the system's distribution, check zone controls, and identify what's causing the imbalance.

🔊

HVAC System Making Unusual Sounds

Banging on furnace startup usually means delayed ignition from a dirty burner. Grinding sounds from an air handler point to a worn blower motor bearing. Clicking without successful ignition suggests a faulty igniter. Hissing near the refrigerant lines can indicate a leak. Each sound corresponds to a specific component issue, and adjusting settings without diagnosing the source doesn't fix the problem.

💡

Pilot Light Won't Stay Lit

A gas appliance pilot that goes out repeatedly almost always has a failing thermocouple. The thermocouple measures pilot flame temperature and holds the gas valve open. When it weakens, the valve closes and the pilot goes out. Repeatedly relighting it without replacing the thermocouple leads to the same result every time. We test the thermocouple output and replace it along with any other pilot assembly components that show wear.

💰

High Energy Bills From HVAC System

A significant increase in heating or cooling costs without a change in usage often means the HVAC system is working harder than it should due to a dirty filter, low refrigerant charge, a failing heat exchanger, or worn electrical components that reduce efficiency. Running an inefficient system causes costs to climb while comfort drops. We inspect the full system, measure output versus input, and identify exactly where efficiency is being lost.

📟

Thermostat Not Holding the Right Temperature

A thermostat that does not maintain the set temperature is often caused by poor placement near a heat source, aging calibration drift in an older unit, or wiring issues that interrupt communication with the heating and cooling equipment. A misreading thermostat forces the system to run longer or shorter than needed, increasing both wear and energy use. We test the thermostat against actual room temperature, check the wiring connections, and replace the unit if calibration cannot be restored.

Reviews

What Our Customers Say

★★★★★

Combined visit saved us a second appointment

We had been meaning to get the AC checked and the furnace was due too. Gas Services Edmonton handled both in one visit and it was noticeably more efficient than booking two separate calls like we used to.

★★★★★

Caught a refrigerant leak before summer

The technician found a slow refrigerant leak during our spring check that we had no idea about. Fixed before it became a real problem in the middle of a heat wave. Really glad we scheduled ahead of the season.

★★★★☆

Thorough visit, took a bit longer than expected

Our system hadn't been serviced in a few years so the visit ran longer than the estimate to properly clean everything. The technician explained why upfront though and the system runs noticeably better now.

★★★★★

Explained the shared ductwork issue clearly

I didn't realize our furnace and AC problems were connected through the same ductwork until the technician from Gas Services Edmonton walked me through it. Made a lot more sense why fixing one side helped the other.

★★★★★

Booked our seasonal visits ahead of time

We set up spring and fall appointments in advance this year instead of calling reactively. Scheduling was easy and the technician was already prepared with our system history when he arrived.

★★★★★

Honest pricing and clear explanation

Gas Services Edmonton gave us a clear price before starting and explained exactly what the combined visit would cover. No pressure to add anything unnecessary, just a thorough check of both systems.
