The Problem

## Markham Heat Pump Problems in Two-Storey Homes

### Bedrooms 3 to 4 degrees hotter than the main floor

**What you notice**The main floor is comfortable, but the bedrooms upstairs run 3 or 4 degrees hotter every July and cooler on January nights.

**Why it happens here**Two-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 it**A 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.

**1\. Strip heat running all January** A unit sized off square footage instead of a Manual J falls short on the coldest nights, and the backup strips quietly double the hydro bill.

**2\. Mild-climate equipment** Standard heat pumps lose capacity fast below -10C. Cold-climate Mitsubishi, Daikin and Fujitsu models hold full output to -15C and keep running to -30C.

**3\. Rebate lost on paperwork** HER+ and HRSP only pay when the pre-retrofit audit happens before install and the model is listed. Miss the order and the file is gone.

Services

## 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.

From **$10,000**

### Central Ducted Heat Pump Toronto

Two-storey homes with the hot-upstairs problem. Whole-home central heat pumps on existing ductwork, with a duct and static pressure check first.

## 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

[/central-ducted-heat-pump-toronto/ →](/central-ducted-heat-pump-toronto/)

.

With gas already on the street, 

dual-fuel is the common pick

[/hybrid-heat-pump-toronto/ →](/hybrid-heat-pump-toronto/)

. 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.

Ontario Rebate Stack

## How much can rebates take off the invoice?

Two programs stack on eligible homes. We book the audits, fill both applications and submit them on your behalf. 40-60% of install cost is commonly offset.

Program 1

### Enbridge HER+

up to $7,100

Cold-climate heat pump replacing gas heat. Pre-retrofit audit first.

Program 2

### Home Renovation Savings Program

$5,000-$10,000

By efficiency tier and household income. Listed equipment only.

Combined

### Stacked total

up to $14,100

Pre-retrofit audit $400-$600, refunded upon install. Post-audit after commissioning.

1.  **1\. Pre-audit** booked before install day. Skip it and the file is usually dead.
2.  **2\. Install** a NEEP / NRCan listed cold-climate model, sized by Manual J.
3.  **3\. Post-audit + file.** We submit HER+ and HRSP for you and track the cheque.

Rebates are "up to" amounts, depend on program terms, audits, equipment listing and household eligibility, and are never guaranteed.

Ask in writing

[/contact/ →](/contact/)

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.
