Trusted HVAC services in Vaughan

Keeping a big home cool on humid days usually comes down to a few repairs: failed capacitors and contactors, dirty outdoor coils, clogged condensate drains and refrigerant leaks. Our 313A-certified mechanics find the cause, locate any leak before adding refrigerant and give you a flat-rate price before they start.

In homes with high ceilings and lots of glass, one air conditioner often can’t cool the upper floor while the basement stays chilly. We check blower settings, return air and duct balance before blaming the equipment.

Air conditioner installation in Vaughan starts with the size of the house: we match the unit to the furnace and ductwork, then compare a ducted heat pump. Variable-speed models run longer at low speed, which pulls more humidity out of the air and evens out temperatures in large open layouts.

Heat pumps work in big homes and compact ones. A cold-climate ducted heat pump can replace your air conditioner and share the heating with your gas furnace in a dual-fuel setup, while ductless mini-splits suit condos, additions, basement suites and single rooms that run too hot or cold.

Large homes sometimes need two heat pumps, or a ducted system plus a ductless head for one problem room. If your home heats with propane or oil, as some rural properties do, a cold-climate heat pump is often a strong fit. Every system is sized with a load calculation.

The Home Renovation Savings Program, run by Save on Energy and Enbridge Gas, is the rebate open to Ontario homeowners right now. What you can get depends on your home and current heating fuel, so we check eligibility with you first. Our heat pump rebates page explains the program.

Large homes use more hot water, dry out faster in winter and sometimes include radiant floors that need a boiler. We repair and replace boilers and radiant systems, tank and tankless water heaters, and the humidifiers, filters and ventilation that keep big homes comfortable, with a flat price first.

Radiant floors and boilers in custom homes

Some custom homes in Kleinburg and Woodbridge heat basements, garages or main floors with radiant loops fed by a boiler. We service circulators, mixing valves, zone controls and expansion tanks, and replace older boilers with condensing or combi units. Our boiler and radiant heat page has more detail.

Hot water for four or five bathrooms

A household with four or five bathrooms can empty a standard tank fast. A tankless unit, or a larger high-recovery tank, keeps up with several showers at once. We check gas line capacity and venting before recommending tankless.

Humidity and air quality

High ceilings and open spaces dry out quickly in winter. A furnace-mounted humidifier keeps humidity steady through the whole house, and a media filter or HEPA bypass catches far more dust than a 1-inch filter. See our indoor air quality page for options.

No-heat and no-cooling emergencies are answered 24/7 and booked first. A big house loses heat steadily once the furnace stops, so try a few safe checks while you wait, but some warning signs mean you should leave the house first.

• Check the thermostat mode, setting and batteries, and on zoned systems check every zone’s thermostat.
• Clear drifted snow or ice off the furnace vent pipes outside.
• Replace a clogged filter, which can shut down a furnace or freeze an AC coil.
• If you smell gas, leave now, avoid switches and phones inside, and call Enbridge Gas at 1-866-763-5427 from outside.
• If the carbon monoxide alarm goes off, get everyone outside and call 911.

Homes with fuel-burning appliances in Ontario must have carbon monoxide alarms, and a large home with bedrooms on several floors needs one near each sleeping area. Ontario’s carbon monoxide safety page (opens in a new tab) has the details. Once the home is safe, we find and fix the cause.

Big houses are the norm here. Many homes in Woodbridge, Weston Downs, Sonoma Heights and Maple have two storeys plus a finished basement, high ceilings and open layouts, and many still run the one furnace and one air conditioner installed when the house was new.

The village cores of Woodbridge and Maple have older homes, while the streets around them grew quickly from the 1980s on. Vellore Village, Patterson and Carrville filled in largely through the 2000s, and Thornhill, west of Yonge, mixes older streets with newer ones.

Kleinburg pairs its historic village with large estate homes, some with radiant floors, several systems or both. Concord and the Vaughan Metropolitan Centre are growing up instead of out, with condo towers and stacked townhomes that need compact furnaces, fan coils or heat pumps. The City of Vaughan (opens in a new tab) is planning the VMC as a new downtown.

Across all of it, good heating and cooling in Vaughan comes down to one question: does the system fit the house as it’s lived in now, with a finished basement, a second kitchen or a home office upstairs?

Most of the problems we fix come from big homes asking a lot of one system, and from 1990s and 2000s equipment reaching the end of its life. Below are the calls that come up most, and what is usually behind them.

• Hot upper floor, cold basement: one thermostat can’t balance three levels, which zoning, duct balancing or a second system fixes.
• Dry air and static in winter: high ceilings and large volumes lose humidity fast without a whole-home humidifier.
• Blower motor failures: large homes keep blowers running long hours, so motors can wear out sooner.
• Tripping limit switches: restricted airflow from dirty filters or closed registers overheats the furnace and shuts it down.
• Zone damper faults: a stuck motorized damper leaves one area hot or cold.
• Running out of hot water: a tank that suited the house when it was new can’t keep up with more bathrooms in use.

Repair or replace depends on age, the failed part and how well the system suits the house today. Many furnaces and air conditioners from the 2000s are now at or near the typical replacement age. We give you both prices and our honest pick.

When replacing in a large home, ask whether zoning, a second system or variable-speed equipment would solve comfort problems that a same-size swap would keep.

Cost depends on the size of the home, how many systems or zones it has, the equipment you choose, and what the ducts, venting and electrical need. Because large homes vary so much, we price every job after seeing the house.

Before we book, we tell you the diagnostic fee. After the diagnosis, you get a flat-rate price, nothing starts until you approve it, and it doesn’t change partway through.

Maintenance should cover every system in the house, twice a year: furnaces and boilers in fall, air conditioners and heat pumps in spring. Each tune-up cleans and tests the parts that wear, checks safety controls and refrigerant, and catches problems before peak season.

Our maintenance plan includes both tune-ups and priority booking, and multi-system homes can have every unit checked in one visit.
