Common HVAC Problems
Scarborough winters are freezing, and the humid summers push HVAC systems to the limit. Scheduling regular servicing keeps your system in shape and helps avoid sudden breakdowns.
No Heating or Cooling
Common causes include a failing thermostat, dirty filters, or a broken compressor.
Frequent Cycling On and Off
Your system may turn off and on too often due to a clogged filter, thermostat issue, or compressor problem. Incorrect sizing can also cause this.
Poor Airflow or Weak Ventilation
Poor airflow often results from blocked vents, dirty filters, or failing fan motors.
High Energy Bills
Older systems, dirty coils, or leaking ducts can cause your unit to overwork and consume more energy.
Strange Noises or Odours
Grinding, banging, or rattling could indicate mechanical failure. A burning or musty smell may mean overheating or trapped moisture.
Gas Leaks & Carbon Monoxide Risks
A cracked heat exchanger or poor gas connection can release carbon monoxide. If you notice a gas smell or your CO alarm goes off, shut down your HVAC system and request emergency service right away.
For Scarborough homeowners, Mersey Heating and Air Conditioning delivers HVAC solutions built to handle the area’s seasonal extremes.

How Often Should I Service My HVAC System?
You should schedule HVAC servicing annually—ideally in spring or fall before heavy use. Regular tune-ups prevent malfunctions, boost performance, and help your system last longer.
How Often Should I Replace My HVAC Filter?
You should replace your filter every 1 to 3 months depending on indoor air quality and system use. Pet hair, dust, and pollen can clog filters quickly. Our team can recommend the right filter type for your setup.
How Much Does HVAC Repair Cost in Scarborough?
HVAC repair costs vary based on the issue and system model. Basic repairs—like changing filters or recalibrating thermostats—are more affordable. More advanced work, such as repairing circuit boards or replacing motors, may cost more but ensures your system works efficiently.
How Long Do HVAC Systems Last?
With proper upkeep, HVAC systems typically last 10–15 years. Heat pumps and boilers often last up to 20. If your system is over 10 years old and frequently breaks down or runs inefficiently, replacement might be more cost-effective. We can help you decide the best solution for your needs.
