Common HVAC Problems
Waterloo’s cold winters and humid summers can strain your HVAC system. Regular HVAC maintenance reduces the risk of sudden issues.
No Heat or No Cooling
Problems like a faulty thermostat, dirty filters, or a broken compressor can stop your furnace or AC from working.
Frequent Cycling On and Off
A dirty filter, malfunctioning thermostat, or wrong system size may cause your HVAC system to short-cycle.
Poor Airflow or Weak Ventilation
Blocked vents, dirty filters, or motor failures can cause airflow problems, making your home less comfortable.
High Energy Bills
Aging equipment, clogged coils, and duct leaks force your HVAC system to work harder, driving up energy costs.
Strange Noises or Odours
Clanking, banging, or grinding sounds may point to loose parts, while burning or musty smells could indicate dust buildup or overheating.
Gas Leaks & Carbon Monoxide Risks
Cracked heat exchangers and damaged gas lines can create dangerous leaks. If you detect gas or your CO alarm sounds, shut off your system and call for emergency service immediately.
Dunn Heating and Air Conditioning offers regular HVAC maintenance and emergency repairs built for Waterloo’s changing seasons.

How Often Should I Service My HVAC System?
Professional HVAC servicing should be done once every year, ideally ahead of the high-demand summer and winter seasons. Yearly maintenance improves energy efficiency, prevents costly breakdowns, and extends your system’s lifespan.
How Often Should I Replace My HVAC Filter?
You should replace your HVAC filters every 1 to 3 months, depending on factors like indoor air quality, pets, and system usage. A clean filter keeps airflow strong and energy bills lower. Our team can recommend the right filter for your system.
How Much Does HVAC Repair Cost in Waterloo?
The cost of repairs varies depending on the issue and type of HVAC system. Basic repairs like changing filters, cleaning coils, or recalibrating thermostats are affordable. More significant repairs, like fixing refrigerant leaks or replacing motors, will cost more.
How Long Do HVAC Systems Last?
Furnaces and air conditioners usually last 10–15 years with proper care, while boilers and heat pumps can last between 15–20 years. If your system is older than 10–15 years, needs frequent repairs, or performs poorly, it might be time to consider a replacement. We’ll help you decide based on your home’s needs and your budget.
