How Fast We Get to You in Markham
Markham is reached off Highway 404, Highway 407, and Highway 7, and we hold a two-hour emergency target across the city. Milliken and south Markham are quickest from Scarborough; Cornell and Cathedraltown add a few minutes on the north-east side.
Highway 404 southbound is heavy in the morning and northbound after 4 PM. For afternoon calls we route on Woodbine, Warden, or Kennedy depending on the address. Unionville and Berczy Village are usually straightforward at any time of day.
Gas emergencies, Enbridge red tags, and no-heat calls are handled 24/7 across all of Markham, including weekends and holidays.
The Homes and Systems We See in Markham
Most of Markham's housing stock is newer, well insulated, and reasonably airtight, particularly through Cornell, Berczy Village, and Cathedraltown. That matters more than people expect: a tight, well-insulated house has a much lower heating load, which is exactly the condition where a cold-climate heat pump performs well.
We see a lot of interest here in dual-fuel systems, where a heat pump handles most of the season and the existing gas furnace takes over only on the coldest days. In practice that setup covers the majority of Markham heating hours on electricity while keeping a reliable backup for a deep January cold snap.
The older parts of Milliken and central Markham are a different story, with 1970s and 1980s homes carrying original ductwork and aging equipment. There we focus on load calculations, venting checks, and combustion safety before recommending any upgrade path.

What Markham customers say
4.9 out of 5 from 150+ customer reviews
We had a cold-climate heat pump installed for our Markham home. They handled all the rebate paperwork and it's kept us warm through the winter. Very knowledgeable about the dual-fuel setup.
Straightforward AC replacement, done in a day, and they explained the SEER2 numbers in plain language instead of just handing me a brochure.
Older home, older furnace. They found a venting issue the previous company missed and fixed it properly. Felt like they were looking out for us.
Local FAQ
Markham HVAC Questions Answered
How quickly can you respond in Markham?
Our target is two hours across Markham, including Unionville, Milliken, Cornell, Berczy Village, and Cathedraltown, with 24/7 coverage for gas emergencies and no-heat calls. Highway 404 congestion can add time to late-afternoon calls, so we route on Woodbine or Kennedy when needed.
Does a cold-climate heat pump actually work through a Markham winter?
Yes. Cold-climate air-source heat pumps listed by NEEP continue producing usable heat well below -15 C. In Markham's newer, well-insulated housing stock they cover the large majority of heating hours. For the handful of extreme days each winter, a dual-fuel setup hands off to your gas furnace automatically.
What heat pump rebates can Markham homeowners get?
Eligible cold-climate installs can qualify for up to $6,500 combined through Ontario's Home Renovation Savings program and federal Canada Greener Homes support. We verify eligibility during the estimate, select a qualifying model from the approved product list, and handle the application paperwork.
Should I keep my gas furnace if I install a heat pump?
In most Markham homes, keeping it makes sense if it is in good condition. A dual-fuel system runs the heat pump for most of the season and switches to gas below a changeover temperature we set for you. That gives you the efficiency gains without losing a proven backup on the coldest nights.
How much does furnace repair cost in Markham?
Diagnostics start at $150 and typical repair calls run $250 to $500 including common parts such as igniters, flame sensors, and pressure switches. We quote the repair before doing it, and if replacement is the better value we will show you the numbers rather than just recommending it.
Do you service older homes in central Markham and Milliken?
Yes. Older Markham homes often have original ductwork and aging venting, so we start with a full safety and airflow assessment. That usually surfaces cheaper, higher-impact fixes than a straight equipment swap.
Which Markham neighbourhoods do you cover?
All of them, including Unionville, Milliken, Cornell, Berczy Village, Cathedraltown, Angus Glen, Greensborough, Thornhill, and Box Grove. We also cover neighbouring Richmond Hill, North York, and Scarborough.
