Trusted HVAC services in Mississauga

Most air conditioner breakdowns come from a short list of faults: a weak capacitor, a burnt contactor, a seized condenser fan, a clogged condensate drain or a refrigerant leak. A 313A-certified mechanic tests each one, finds any leak before recharging, and quotes a flat price you approve first.

Mature trees shade Lorne Park, Mineola and Port Credit, but leaves, seed fluff and sap clog outdoor coils fast. A condenser that can’t shed heat runs hotter and wears its compressor out sooner, so a coil cleaning is often part of the fix.

Air conditioner installation in Mississauga starts with a cooling load calculation, not the old unit’s size. Many older homes had central air added onto ducts sized for heating, so we check airflow and the indoor coil before matching a new SEER2-rated condenser to the furnace. If yours still runs on R-22, a refrigerant that’s no longer made, price a heat pump too.

Heat pumps come in two main forms: a ducted cold-climate unit that replaces your central AC and works alongside the furnace, or ductless mini-splits mounted in the rooms that need them. Both cool all summer and heat efficiently through most of the winter, and we size either with a room-by-room calculation.

Eligible heat pumps can earn rebates through the Home Renovation Savings Program from Save on Energy and Enbridge Gas. The amount depends on the home and the fuel it heats with now, and we confirm eligibility before you commit. See our heat pump rebates page.

Boilers, water heaters and indoor air quality equipment get the same care as your furnace and AC. We fix and replace hydronic boilers, tank and tankless water heaters, and whole-home humidifiers, filters and HRVs, with a flat price approved before any work.

Boilers and radiant floors

Some older homes in Streetsville and Port Credit still heat with hot water radiators, and some custom homes use in-floor radiant heat. We repair pumps, zone and mixing valves and expansion tanks, and replace worn boilers with condensing or combi models.

Tank or tankless water heaters

Gas tank water heaters typically last 8 to 12 years; tankless units run about 20 with yearly descaling and never run out mid-shower. Tankless needs enough gas supply and proper venting, so we check both and price a tank alongside it.

Indoor air quality

Original ducts tend to move dust around, while tight newer townhomes trap humidity and cooking smells. A higher-MERV media filter, a humidifier on a humidistat, or an HRV or ERV fixes the cause. See our indoor air quality services.

Emergency calls are part of our HVAC services in Mississauga: we answer no-heat and no-cooling calls 24/7 and put them ahead of tune-ups and quotes. Deal with safety first, then try a few simple checks that sometimes get the system running again before the technician arrives.

No heat

Check that the thermostat is on heat and above room temperature, the furnace switch and breaker are on and the filter is clean. On a high-efficiency furnace, check that snow or ice isn’t blocking the plastic vent pipes outside.

No cooling

Check the breaker, the outdoor disconnect and the filter. If the refrigerant lines are iced, switch the system off to thaw, since running it frozen can ruin the compressor.

Gas smell or carbon monoxide alarm

If you smell gas, leave at once without touching switches or using your phone indoors, and call Enbridge Gas at 1-866-763-5427 from outside. If a carbon monoxide alarm sounds, get everyone out and call 911. Every Ontario home with a fuel-burning appliance needs working CO alarms, and the provincial carbon monoxide guide (opens in a new tab) explains the rules.

Heating and cooling in Mississauga follows the city’s building booms. Much of it went up from the 1950s to the 80s in Applewood, Cooksville, Malton, Erindale, Erin Mills and Meadowvale, and many of them now have a second or third furnace pushing air through original ducts sized for heat, not central air.

Bungalows, back-splits and side-splits are common there. Split levels tend to run cool on the lowest floor and warm in the top bedrooms.

Along the lake, Port Credit, Mineola, Lorne Park and Clarkson mix older homes on large, treed lots with custom homes that replaced original bungalows. The new builds often need zoning or two systems; the older houses need help with ducts and venting.

Streetsville and Meadowvale Village keep their historic cores, so check with the City of Mississauga (opens in a new tab) about heritage approvals before exterior changes. Lisgar and Churchill Meadows, built mostly from the 1990s on, have many townhomes and semis with compact mechanical rooms.

Most of the problems we fix trace back to aging equipment, ductwork never sized for central air, and outdoor units working hard under mature trees. Here are the usual causes behind each one, and every repair is priced flat before any work starts.

• Uneven split levels: one thermostat can’t read four floors, so we look at blower speed, balancing dampers and returns.
• Weak airflow from original ducts: crushed runs, open joints and too few returns cut comfort and efficiency.
• Clogged outdoor coils: leaves and seed fluff block the condenser and strain the compressor.
• Flame sensor and ignitor faults: the furnace lights and then shuts off, or never lights at all.
• Blocked furnace vents: snow or ice over the intake and exhaust pipes can lock out a high-efficiency furnace.
• Short cycling in townhomes and condos: oversized equipment turns on and off constantly and never dries the air.

Repair is usually the right call when equipment is well short of its typical lifespan and the fault is a single part. Replacement deserves a serious look near the end of its life, after a heat exchanger or compressor failure, or once it has become a regular service call. We price both.

Many homes here are already on their second furnace, so the question is often whether to replace the furnace and AC together. Doing both means one installation and equipment designed to work as a pair.

HVAC costs vary with the equipment and its efficiency, the size of the home, the condition of the ducts and venting, and any electrical or gas work. That’s why we look before we quote, and the price you approve is the price you pay.

Whatever the job, HVAC services in Mississauga from us are priced flat and agreed before work begins. When you compare any HVAC contractor in Mississauga, ask whether the price is fixed, who does the gas work and whether the warranty is in writing.

HVAC maintenance in Mississauga comes down to two visits a year: a furnace tune-up before the heating season and an air conditioner tune-up before the first humid stretch of summer. Our maintenance plan includes both, plus priority booking when the phones are busiest.

In the fall we clean the burners and flame sensor, inspect the heat exchanger, test the safety controls and check gas pressure. In the spring we clean the condenser coil, check refrigerant pressures and clear the condensate drain. The details are on our maintenance plan page.
