Markham Heat Pump Problems in Two-Storey Homes
Bedrooms 3 to 4 degrees hotter than the main floor
What you noticeThe main floor is comfortable, but the bedrooms upstairs run 3 or 4 degrees hotter every July and cooler on January nights.
Why it happens hereTwo-storey detached homes in Unionville, Berczy Village and 1990s-planned Cornell keep the furnace and AC in the basement, pushing air two floors up through returns that are often undersized upstairs.
How we fix itA static pressure test, an added upstairs return, then a central ducted heat pump whose longer, slower runs even out the floors. Dual-fuel keeps the furnace for the deepest cold.
Central and Dual-Fuel Heat Pump Services
Markham heat pump work is mostly two-storey ducted homes on gas. Unionville, Berczy Village and Cornell detached homes have a furnace and central AC in the basement and a bedroom floor that runs hot in July, so the fix starts in the ducts.

What GTA homeowners say
Real installs across Toronto neighbourhoods. Rebate captures and winter performance in the owners' own words.
"They tested the ducts before quoting and added an upstairs return. First summer the bedrooms aren't 4 degrees hotter than the kitchen."
"Converted our Rosedale home from oil to Mitsubishi Hyper-Heat in October. Two winters, zero backup heat needed. Enbridge HER+ Oil-to-HP bonus came through at $7,100 and HRSP added $4,800. Combined covered 65% of the project."
"Our board approved on first submission. Six residents replaced PTACs the first month and the board scheduled a bulk upgrade after that."

Heat Pump Work from Milliken to Cornell
Heat pumps in Markham are mostly two-storey ducted homes on gas. Unionville, Berczy Village and Cornell detached homes have a furnace and central AC in the basement and a bedroom floor that runs 3 or 4 degrees hotter in July. The fix starts in the ducts: static pressure test, added upstairs return, then a central heat pump.
With gas already on the street, dual-fuel is the common pick. Heat pump most of the winter, furnace below the balance point. The Unionville Carrier install near Main Street Unionville evened out the floors front to back.
Cornell was master planned in the 1990s as a New Urbanist community with homes set close together, so we place outdoor units away from the neighbour's bedroom window. In the Unionville Heritage Conservation District, exterior alterations need a heritage permit, which we build into the schedule.
Housing stock we see most: Suburban two-storey detached homes on gas with central AC; hot upstairs rooms are the common complaint.
Two-storey detached homes on gas
Two-storey suburban detached. Unionville, Berczy Village, Cornell, Cathedraltown and Wismer homes have a gas furnace and central AC in the basement, ducts to every room, and almost always the same complaint: the upstairs runs 3-4 degrees hotter in July. The cause is undersized or missing second-floor returns.
We fix the duct side first: static pressure test, added upstairs return, Manual D on any section that needs it. Then the heat pump. Long, slow inverter run cycles mix the house far better than a single-stage AC that blasts and shuts off. The Unionville Carrier Infinity 24VNA6 4-ton job near Main Street Unionville evened out the floors front to back.
Gas on the street. With gas already in, dual-fuel is the common pick: heat pump most of the winter, furnace below the balance point.
Covering Milliken to Cornell
Crews come up the 404 and the 407, then along Highway 7 and 16th Avenue for Unionville, Berczy Village and Cathedraltown, and down Kennedy and McCowan for Milliken and Wismer. Driveways, garages and wide side yards make delivery easy.
Most jobs here are ducted, so the first visit includes a static pressure test and a look at the return layout upstairs. That's where the comfort problem usually lives.
Response times: same-day no-heat dispatch, phone answered 24/7.
York Region winters and summers
It is colder than downtown Toronto on winter nights and hotter upstairs in summer. Both point to the same answer: a properly sized variable-speed heat pump on ducts that move enough air. The city is on Alectra Utilities, which feeds into the dual-fuel switchover setting.

Markham Heat Pump FAQ
Why is my upstairs so hot in my Cornell house, and will a heat pump fix it?
Usually undersized returns upstairs. We fix the duct side first, then the heat pump's longer, slower runs even it out.
Dual-fuel or full-electric for a two-storey home on gas?
Both work. Dual-fuel keeps your furnace for the deepest cold, and full-electric can earn a larger fuel-switch rebate. We price both on Alectra and Enbridge rates.
I live in the Unionville heritage district. Can I still add a heat pump?
Yes. Exterior alterations inside the Unionville Heritage Conservation District need a permit from Markham council, so we plan a rear or side location and build the review time into the schedule.
Will a heat pump be loud next to my neighbour's house?
Inverter outdoor units are quiet, especially at low speed. We place them away from bedroom windows on both sides.
Can you add a return without opening up my walls?
Often yes, through a closet or a hallway wall cavity with minimal patching. We plan the route on the first visit.
What does a central heat pump with added returns cost in Markham?
Central ducted 3-ton $10,000-$16,000, cold-climate 4-ton $14,000-$22,000, dual-fuel $12,000-$20,000. Added returns are quoted upfront after the static pressure test.
