What we do

Every degree, covered

Heating, cooling, hot water and air quality — installed fast and priced straight, residential and commercial, across the GTA & Hamilton.

Furnace Repair

Most furnace repairs in Burlington, Oakville and Hamilton cost $150–$450 and finish on the first visit; the $90–$150 diagnostic is folded into the repair if you go ahead. A TSSA-licensed technician finds the fault, quotes it in writing, and says plainly whether the furnace is worth fixing.

Heating

Heating a Burlington, Oakville or Hamilton house comes down to three choices: a high-efficiency gas furnace at $4,500–$7,500 installed, a 3-ton cold-climate heat pump at $9,500–$15,000 before rebates of up to $7,500, or a hybrid of the two. We size by heat-loss calculation and put the price in writing first.

Cooling

Cooling a Burlington, Oakville or Hamilton house costs $4,500–$5,800 for a 16 SEER2 central air conditioner, $5,500–$7,000 for a two-stage 3-ton system, or $4,000–$6,000 for a single-zone ductless — and the right size is set by lake-effect humidity as much as heat. Most repairs run $150–$800 and finish in one visit.

Air Conditioner

AC repair in Burlington, Oakville and Hamilton runs $150–$800, and the three most common failures — a capacitor, a contactor, a clogged condensate drain — are fixed in one visit for $150–$450. Past 12 years old, we quote the repair beside a new 16 SEER2 install at $4,500–$5,800 and let the math decide.

Water Heater

Water heater repair in Burlington, Oakville and Hamilton runs $150–$800; a tank-for-tank replacement is $1,200–$2,500 installed and takes 2–4 hours. A tank leaking from the bottom is finished — shut the cold inlet and the gas valve or breaker, then call. Everything else is usually a part.

Tankless Water Heater

A tankless water heater conversion in Burlington, Oakville or Hamilton lands at $4,200–$5,000 installed for a 199,000 BTU Rinnai or Navien replacing a tank, or $3,500–$6,500 across the full range with venting and gas-line work counted. Sized against winter inlet water, it runs 15–20 years and never runs out.

Emergency Services

Emergency HVAC service costs the same here as a weekday visit: the diagnostic is $90–$150 day, night or holiday, typical emergency repairs run $150–$800, and there's no overtime, weekend or holiday surcharge. A person answers (647) 801-1252 around the clock; gas smells and CO alarms go to Enbridge and 911 first.

Residential HVAC

Residential HVAC from one licensed crew means the furnace, air conditioner, water heater, ducts and air quality get diagnosed as one system. Repairs run $150–$800, a high-efficiency furnace installs for $4,500–$7,500, and replacing furnace and AC together saves $1,000–$2,500 in overlapped labour — quoted in writing, always.

Commercial HVAC

Commercial HVAC for Burlington, Oakville and Hamilton businesses covers rooftop units, splits, make-up air and exhaust — maintained on contract with a written condition report per unit, replaced on a planned crane day, and repaired at the same rates after hours as during them.

Indoor Air Quality

Indoor air quality in a Burlington, Oakville or Hamilton house comes down to three systems: filtration, humidity and ventilation. A media filter cabinet runs $400–$700, a bypass humidifier $500–$900 installed, a whole-home dehumidifier $1,500–$3,000, an HRV service $150–$300 — and the right one is chosen from your symptom, not a catalogue.

Duct Cleaning

Duct cleaning for a typical Burlington, Oakville or Hamilton house costs $300–$700, and $700–$1,000 for a large home with 20+ vents or two systems. The number quoted on the phone is the number at the door — and if the ducts don't need doing yet, we say so before the hoses come off the truck.

Maintenance Plans

A plan that bundles the fall furnace tune-up with the spring AC tune-up runs $150–$350 a year, against $240–$500 of standalone value — single visits are $120–$250 each. What you're buying is that the small faults get found on a Tuesday in October instead of at 2 AM in January.
