FAQ

Most heating and cooling equipment should be professionally inspected about once a year. Furnace maintenance is ideally completed before the heating season, while AC maintenance is best scheduled before summer. Regular servicing can help identify wear, airflow problems and efficiency issues before they become larger repairs.

Common signs can include frequent cycling, uneven temperatures, difficulty maintaining the thermostat setting or a system that runs for unusually long or short periods. These symptoms can also have other causes, so an HVAC assessment is the best way to determine whether equipment sizing, airflow or another issue is responsible.

AFUE is used to describe furnace heating efficiency, while SEER2 is used to compare cooling efficiency for air conditioners and heat pumps. In general, higher efficiency ratings indicate equipment designed to use energy more efficiently, but the best system should also be properly sized and matched to the home.

HVAC equipment should be sized based on more than square footage. Home layout, insulation, windows, ductwork, number of storeys and heating or cooling load all affect the appropriate system size. Oversized or undersized equipment can reduce comfort and efficiency, so proper sizing should be confirmed before installation.

Both systems can cool a home by transferring heat outside. A heat pump can also reverse the process to provide heating, while a standard air conditioner only provides cooling. For homeowners replacing both heating and cooling equipment, comparing a heat pump with a traditional AC and furnace setup can be worthwhile.

Yes, eligible Ontario homeowners may qualify for incentives through the Home Renovation Savings program. Rebate amounts vary by heating source, equipment and eligibility requirements, so confirm eligibility before installation.
