Air Conditioner Services in Burnaby, BC: Repair, Maintenance & Installation

Cooling Faults We See Most Often

Most cooling failures trace back to a handful of common faults, and we have diagnosed all of them across Burnaby, Vancouver, and Coquitlam for over two decades.

• Not cooling at all. When the system runs but the home never reaches the set temperature, the cause is usually a failed capacitor, a seized compressor, or a tripped breaker starving the outdoor unit of power.
• Warm air from the vents. Warm supply air often points to low refrigerant, a dirty air filter restricting airflow, or a thermostat set to the wrong mode.
• Refrigerant leak. A slow leak lowers cooling capacity over time. We locate it, repair it, and recharge the system to the manufacturer specification rather than simply topping it up.
• Frozen evaporator coil. Ice on the indoor coil is usually caused by restricted airflow or low refrigerant, and it shuts down cooling until the coil thaws and the root cause is corrected.
• Unusual noises. Grinding, buzzing, or rattling can signal a failing fan motor, a loose component, or a struggling compressor that needs attention before it fails outright.
• Will not turn on. A unit that will not start may have a wiring fault, a blown fuse, a bad capacitor, or a clogged condensate drain that has tripped the system safety switch.

Central Air or Ductless: What Fits Your Home

A central air conditioner moves cooled air through ductwork from a single indoor coil, so faults tend to affect the whole home at once and show up as weak airflow, duct leaks, or a problem at the shared evaporator coil. It is the natural choice for a home that already has ducting in place.

A ductless system cools individual zones through wall-mounted indoor heads tied to an outdoor compressor. Because each head has its own coil and blower, comfort is zone by zone and a fault is usually isolated to one room. Ductless suits character homes and condos without ductwork, and the same equipment heats as well as cools. See our mini-split services and heat pump services if that is the direction you are leaning.

What Annual AC Service Includes

Regular maintenance is what keeps a cooling system efficient and catches small problems before they strand you in a heat wave. A Maple Furnace air conditioning service covers the same ground every visit:

• Cleaning and inspection of the coils, filters, condenser, and evaporator so dirt and debris are not throttling performance.
• Refrigerant check to confirm the charge is at the level the system was designed for.
• Thermostat calibration and testing for accurate temperature control.
• Electrical and mechanical checks across connections, motors, capacitors, and fans.
• Condensate drain clearing and a performance test to confirm the system cools correctly.

Ask us about putting your cooling service on the calendar each spring through our maintenance and tune-up program, before the first warm week of the year.
