Water heater repair in Ottawa
Local HVAC company
HVAC Services Ottawa is a local heating and cooling company serving homes, condos, rental properties and businesses across the city, 24 hours a day, 7 days a week. We repair, maintain, replace and install furnaces, heat pumps, boilers and water heaters, every major brand.
We know the 1990s gas furnaces in Kanata and Barrhaven subdivisions, the boilers and radiators in Glebe and Westboro century homes, the new-build heat pumps in Riverside South and Stittsville, and the propane and oil systems out in Manotick, Greely and Carp. Different streets, different failures, same truck.
Why people call us
A house with no heat at −30 or a store with no AC during a heat warning can't wait until Monday. Here's what fills our dispatch board from Orléans, Nepean, Barrhaven and Gloucester.
Furnace clicking but not lighting, heat pump stuck in defrost, boiler locked out. At −30, pipes freeze in hours. Our fix: a technician dispatched the same day with igniters, sensors, capacitors and boards on the truck.
Unit runs but blows warm, coil frozen solid, compressor won't start. Other companies quote a week out. Our fix: air conditioning repair in Ottawa within hours, refrigerant and capacitors in stock.
A clogged filter, a heat pump that lets the backup strips do all the work, a furnace short-cycling. You don't see it, you pay for it. Our fix: a tune-up that finds the leak in your budget, with the readings on paper.
A bang on ignition, a burning smell, a carbon monoxide detector going off. These come before the full breakdown. Our fix: call now, not at 2 a.m.; if it's gas you smell, leave the house and call Enbridge first.
How a call works
You don't need to know if it's the thermostat, the furnace or the heat pump. Tell us what you see and hear; we take it from there.
We tell you what to check meanwhile (breaker, filter, thermostat) and dispatch the technician closest to your address.
The technician tests the system, finds the cause and shows you the failed part.
You get the full price before we touch anything. Yes or no. The number doesn't change halfway through.
Most are done the same visit. If a part must be ordered, you get a date and we come back.
Homes and businesses
At home, no heat is a cold night. In a business, it's a lost day of sales, staff sent home and customers walking out. We treat both as emergencies.
Detached homes, townhouses, semis, condos and rental units across Ottawa. Furnace, heat pump, boiler, water heater.
Offices, retail, restaurants, garages and multi-unit buildings. Rooftop units, commercial boilers, high-capacity water heaters, maintenance contracts.
FAQ
It depends on the part. A capacitor, igniter or thermostat is the low end of HVAC repair; a control board, blower motor or gas valve the middle; a compressor or heat exchanger the top, where we compare against replacement. We don't quote over the phone because we don't guess: the technician diagnoses on site and hands you a flat-rate price in writing before any HVAC repair starts.
Yes. Emergency furnace repair, heat pump repair, boiler repair and water heater repair, nights, weekends and holidays, across Ottawa: Orléans, Kanata, Nepean, Barrhaven, Gloucester, Stittsville. Call (613) 701-6014; we tell you what to check while you wait and send the technician nearest to you. If you smell gas, leave the house and call Enbridge's emergency line first.
Repair, maintenance, replacement and installation of furnaces (gas, propane, electric), heat pumps (ductless, central, cold-climate), boilers (gas and combi) and water heaters (tank and tankless), plus central air conditioning repair. Residential and commercial. One HVAC company for everything in the mechanical room.
Three tests: do they actually answer 24/7, do they send a technician the same day, and do they give the price in writing before touching the equipment. HVAC Services Ottawa passes all three. Avoid any heating and cooling contractor who quotes a full replacement before a diagnosis.
Under 12–15 years and the repair costs less than a third of a new unit: repair. Older, a cracked heat exchanger, or a second major failure in two winters: we show both options with prices. Rebate programs for heat pumps and high-efficiency furnaces exist in Ontario; the rules change, so we tell you what applies at the time.
Once a year per system: heating service in the fall, cooling service in the spring. An HVAC tune-up takes about an hour and prevents most of the January and July emergency calls. Change the filter every three months between visits.

Reviews
Homes and businesses in Orléans, Kanata, Barrhaven, the Glebe and Centretown. Furnaces, heat pumps, boilers, water heaters and central AC.
Furnace quit on a Sunday night in January, −29 outside, two kids. I searched "hvac repair near me" and HVAC Services Ottawa picked up on the second ring. Tech was in Orléans within the hour, cracked igniter, had one on the truck. Price quoted on the phone is what I paid.

Central AC blowing warm during the July heat warning. Three heating and cooling companies in Ottawa quoted me a week out. These guys came the next morning, found a refrigerant leak at the coil, fixed it on the spot. Fastest HVAC repair in Ottawa I've had, and the house was 22 by dinner.

1920s house in the Glebe with radiators, boiler locking out every few days. Two other HVAC companies told me to replace it. Their tech bled the system, changed the relief valve and a circulator, showed me the old parts. Honest heating repair instead of a $9,000 upsell.

New build in Riverside South, cold-climate heat pump iced solid at −24 and the backup heat never kicked in. Googled "heating and cooling near me", picked the one with real reviews. Defrost sensor and a relay, fixed same day. He also explained why the Hydro Ottawa bill had jumped. Great HVAC service.

Rental water heater leaking, rental company said five business days. HVAC Services Ottawa came that afternoon with a tank, showed me what I'd paid in rent over 11 years, installed my own and told me what to ask before returning the old one. Hot water by 6 p.m. Now they do our furnace and AC maintenance too.

I run a café on Bank Street in Centretown. Rooftop unit died Friday at 11, dining room at 30 degrees, weekend rush coming. HVAC Services Ottawa was on the roof before 2: condenser fan motor and a contactor. Open for dinner. Commercial HVAC repair done right, and they handle both our units every spring and fall now.
