What we see most in Richmond Hill
- Large two- and three-storey homes in Bayview Hill and Westbrook with one furnace trying to heat and cool three levels. The top floor is too warm in summer and the basement too cool in winter. Two-stage equipment, better returns and sometimes zoning help.
- Humid summers in finished basements. An AC that’s oversized, or a fan left on all the time, leaves basements damp. Our post on summer humidity in Richmond Hill homes goes into it.
- Dry winters upstairs. Humidifiers that were turned off or never serviced. See our guide to whole-home humidifiers.
- Tankless water heaters in homes with several bathrooms. Undersized units or skipped descaling are the usual problems.
Repair calls
For no-heat calls, the common culprits are the same everywhere: flame sensors, igniters, pressure switches and plugged condensate drains. Write down the blinking code before you reset the furnace; our furnace blinking light guide explains how.

What our customers say
Questions we get in Richmond Hill
Why is my top floor always hot?
Usually a mix of not enough return air upstairs, a single-stage AC, and heat gain through the roof. We can measure airflow and tell you which matters most.
How often should a tankless water heater be descaled?
In most GTA homes, once a year. Hard water or heavy use can mean more often.
Do you install heat pumps in Richmond Hill?
Yes, both ducted and ductless, and we check which rebates may apply when we quote.
