Often caused by improper sizing, sensor issues, or restricted airflow.
Poor Airflow or Weak Ventilation
Might be due to clogged vents, blower motor issues, or duct blockages.
Rising Energy Bills
Worn components or dirty coils make your system work harder, driving up costs.
Strange Noises or Odours
Loud clanging, buzzing, or unusual smells may point to mechanical or electrical issues.

How Often Should I Service My HVAC System?
A full HVAC inspection and tune-up should be done once a year. Ideally, schedule your service in the spring before cooling season or fall before heating season for maximum efficiency and reliability.
How Often Should I Replace My HVAC Filter?
Filters should be replaced every 1–3 months depending on your system, usage, pets, and air quality. A clean filter improves airflow and helps protect internal components from dust buildup.
How Much Does HVAC Repair Cost in St. Catharines?
It varies depending on the issue. Simple fixes like replacing a capacitor or cleaning a sensor are affordable. Larger jobs—such as blower motor or circuit board replacement—cost more. You’ll always get an upfront quote before we begin.
How Long Do HVAC Systems Last?
Furnaces and air conditioners typically last 10 to 15 years. Boilers and heat pumps can often reach 15 to 20 years with routine care. If your system is nearing the end of its lifespan or breaking down frequently, our team can help you decide whether repair or replacement makes more sense.
