HVAC Service Built for Hamilton Homes

Hamilton's housing runs from century brick homes in Westdale and the lower city to brand-new builds in Binbrook and Glanbrook. The Niagara Escarpment also means upper-mountain homes see colder temperatures and heavier snow than the lower city, so proper system sizing matters more here than most places.

EcoFrost serves all of Hamilton, including Ancaster, Dundas, Stoney Creek, Waterdown, Flamborough and Mount Hope. Our technicians know the City of Hamilton permit process and handle the paperwork so your install passes inspection the first time.

Credentials That Matter in Ontario

Anyone can call themselves an HVAC company. These are the credentials Hamilton homeowners should verify before they hire anyone.

TSSA Certified Contractor

Ontario's gas-equipment regulator licenses our team to install and repair every residential gas system.

Authorized Lennox Dealer

We chose Lennox as our preferred partner because their efficiency and quiet operation lead the industry.

HRAI Member

Heating, Refrigeration and Air Conditioning Institute of Canada membership means our trade practices meet national standards.

G1 and G2 Gas Licensed

Every tech on our crew holds the gas licenses Ontario requires for residential furnace and water heater work.

Why Hamilton Homeowners Pick EcoFrost

Six concrete reasons that show up on the invoice, not in the marketing.

Same-Day Dispatch Across Hamilton

We staff for emergencies. Most service calls get a real arrival window in seconds, not a vague 8-hour bracket. We cover the full city, from the lower-city core to the upper mountain, plus Ancaster, Dundas, Stoney Creek and Waterdown.

$0 Overtime Fees, Ever

Nights, weekends, holidays. Our rate stays the same. Other contractors charge 1.5x to 2x for after-hours calls. We do not, because emergencies do not pick business hours.

Flat-Rate Pricing in Writing

We diagnose first and quote before any parts go in. No surprise add-ons at the end. You see the full price in writing and approve it before we start the repair.

Rebate Paperwork Handled For You

The Ontario Home Renovation Savings Program and the federal Oil to Heat Pump Affordability program can stack to over $10,000 on some heat pump installs. We complete and submit every form on your behalf at no extra cost.

TSSA Red Tag Removal

If another contractor or the gas utility red-tagged your furnace, we offer a free second opinion and remove the tag the same day when the equipment is safe to operate.

10-Year Labour Warranty on New Installs

Our labour warranty doubles the typical industry coverage. Combined with the manufacturer's parts warranty, you are protected for a full decade after install.

Ecofrost installed a new air conditioner for us in late August. Our 23 year old AC finally gave out. Nisar quoted us a very good price on a Lennox. They were able to install it the next day. They were very professional and knowledgeable and we are very happy with the service that was provided. It is nice to have a great company that you can count on in the community.

I am extremely pleased with Nisar and his team for the professionalism, a mind for customer satisfaction, attention to detail and last but not least their focus on completing the job with precision and due care. Nisar came in with knowledge and patience to answer all my questions and got us the best deal on AC.

What an amazing experience with this company at a time where I was really helpless! My furnace finally went down after 22 years and this company took all my worries away! They responded immediately, came up with a plan and stuck to it by being on time, professional, friendly, kind, and patient.
