"Furnace died on the coldest night of the year. Called Summit at 11pm and they had a tech here by midnight. Diagnosed the issue, gave us a clear price, and had us warm again by 2am. Unreal service."

"Had them install a heat pump last spring. Our gas bill dropped by almost half. They sized the system properly, explained the rebate programs, and the install was clean and fast. Highly recommend."

"Annual maintenance — they've been tuning up our furnace and AC for three years now. Always on time, always thorough, and they catch small things before they become big bills. Worth every penny."
— Rob T.
Maintenance Plan — Google Review
An oversized furnace short-cycles and wastes energy. An undersized AC runs all day and never cools the house. Most comfort problems come down to one thing: the system wasn't sized properly in the first place.
We do a full load calculation on every install — not a guess based on square footage. That means the right equipment, running efficiently, keeping your home comfortable year-round and your bills predictable.
Proper Load Calculation
We measure your home's insulation, windows, layout, and orientation — not just square footage.
Lower Energy Bills
A properly sized system uses less energy. Most homeowners see a noticeable drop in their monthly bills.
Longer Equipment Life
Equipment that runs as designed lasts longer. No short-cycling, no overwork, fewer repair calls.
Even Comfort Throughout
No hot rooms upstairs, no cold spots by the windows. Proper sizing means consistent temperature everywhere.
Tell us what's happening — no heat, no AC, weird noise. We'll schedule a time that works for you, often same-day.
Our tech arrives on time, inspects your system, and explains exactly what's going on — in plain language, not jargon.
You get a clear price before we start. No surprises. If the price changes for any reason, so does your approval.
We complete the work, clean up, and walk you through everything. Every job is backed by our parts and labour warranty.
Or book online — we'll confirm within 30 minutes.
Furnace failures, gas leaks, carbon monoxide alarms, frozen pipes — don't wait. We dispatch a licensed HVAC technician to you right away.
Available 24 hours, 7 days a week

I started Summit Climate after years of watching bigger companies overcharge homeowners and push equipment they didn't need. A family with a 10-year-old furnace doesn't need a $12,000 replacement — they need someone who'll tell them the truth and fix what's actually broken.
That's the business I built. We show up on time, give you an honest diagnosis, and only recommend what's actually necessary. If your system can be repaired, we'll repair it. If it's time for a replacement, we'll help you choose the right one — properly sized, properly installed, and at a fair price.
Every technician on our team is TSSA registered, background-checked, and trained to treat your home with respect. We wear boot covers, lay down drop cloths, and clean up when we're done. Our reputation is everything — and it shows in our reviews.
We provide residential and commercial heating and cooling services across the region. Furnace repairs, AC installs, heat pumps, duct work — if it keeps your home comfortable, we handle it.
Most repairs can be scheduled same-day. Not sure if you're in our service area? Give us a call — if we can help, we will.
Answers to the things homeowners ask us most.
How quickly can you get here for an emergency?
Our emergency line is available 24/7. For no-heat calls in winter or no-AC in summer, we typically dispatch a technician within 60–90 minutes during business hours, and same night for after-hours calls.
Do you charge for estimates?
For most residential work, no. We provide free on-site estimates. You'll know the full cost before we start — no obligation, no pressure.
How do I know if I need a repair or a replacement?
We'll always try to repair first if it makes economic sense. As a rule of thumb: if your system is under 12 years old and the repair is under half the replacement cost, we'll recommend the repair. We'll lay out both options with clear pricing so you can decide.
What brands do you install?
We're not locked into one brand. We install Lennox, Carrier, Daikin, Mitsubishi, Goodman, and others — and recommend based on your home's needs and your budget, not our margins.
Do you offer maintenance plans?
Yes. Our annual maintenance plan includes a fall furnace tune-up and spring AC check-up. Regular maintenance catches small issues early, extends equipment life, and keeps your warranty valid. Ask us for details.
Heating or cooling — we'll get it sorted. Free estimates. Upfront pricing. Licensed, insured, and ready to work.
