Don’t Wait: Running a struggling air conditioner will spike your hydro bill and can permanently damage the compressor. Our technicians carry universal parts to fix these issues on the spot.
The cost of a furnace installation in Vaughan depends on the size of your home, the efficiency rating (AFUE) of the new unit, and whether any ductwork or gas line modifications are required.
We provide transparent, flat-rate quotes with zero hidden fees. Here is a breakdown of what influences the final price:
| Cost Factor | Description |
| Home Size (BTUs) | Larger Kleinburg estates require higher BTU capacity furnaces compared to Maple townhomes. |
| Efficiency Rating | High-efficiency models (96% AFUE or higher) cost more upfront but save you hundreds on monthly gas bills. |
| Brand Selection | Premium brands like Lennox and Carrier vary in price compared to budget-friendly options. |
*Tip: We help you offset the initial cost by applying for Enbridge Home Efficiency Rebates!
We offer priority, same-day service for emergency “no heat” situations. When the temperature drops during an Ontario winter, you cannot afford to wait. Our TSSA-certified technicians arrive in fully stocked trucks to perform your furnace repair in Vaughan in a single visit.
Typical Furnace Repair Timelines:
| Furnace Issue | Urgency Level | Typical Repair Time |
| Dirty Flame Sensor | High (No Heat) | Under 1 Hour |

| Enbridge Red Tag | Critical (Gas Shut Off) | Same-Day Correction |

When you choose Heat Flow HVAC for your AC installation in Vaughan, we guarantee full bylaw compliance so you never have to worry about neighborhood disputes or municipal fines. We specialize in installing ultra-quiet inverter heat pumps and air conditioners that operate as low as 55 decibels.
Deciding between a quick fix and a full replacement depends on the age and condition of your unit. As a general rule, if your system is over 15 years old and the repair costs more than 50% of the price of a new unit, a complete furnace installation in Vaughan is the smarter financial choice.
Repair vs. Replacement Guide:
| Decision Factor | When to REPAIR | When to INSTALL NEW |
| System Age | Under 10 Years Old | 15+ Years Old |
| Repair Cost | Under $500 (Minor parts) | Over $1,000 (e.g., Cracked Heat Exchanger) |

For a direct replacement (swapping an old furnace or AC for a new one in the exact same location), you generally do not need a building permit from the City of Vaughan.
However, if your furnace installation in Vaughan requires moving gas lines, installing new ductwork, or making structural changes to your home, a permit is required. Heat Flow HVAC is TSSA certified and handles all necessary gas tagging, code compliance, and safety checks so you do not have to worry about the paperwork.
To keep your system running efficiently and to prevent sudden breakdowns, we recommend scheduling professional maintenance twice a year:
Regular maintenance not only prevents costly furnace repair in Vaughan, but it is also required by most major manufacturers (like Lennox and Carrier) to keep your system’s warranty valid. Ask us about our $99 Tune-Up Special!
Vaughan is known for having moderately hard water (7 to 8 grains), which contains high levels of calcium and magnesium. Over time, this mineral buildup (scale) can wreak havoc on water-connected HVAC appliances like tankless water heaters and whole-home humidifiers.
If you have a humidifier attached to your furnace, scale can quickly clog the water panel, restricting airflow and preventing proper moisture distribution during our dry winters. To combat this, we recommend regular maintenance and installing a high-quality system with proper filtration. Learn more about our specialized humidifier services to protect your home’s air quality and hardwood floors from hard water damage.
Absolutely! Heat pumps are becoming incredibly popular for Vaughan homeowners. Unlike a standard air conditioner that only provides cooling, a cold-climate heat pump offers both high-efficiency AC installation in Vaughan during the summer and reliable heating during the winter.
By switching to a hybrid system (a heat pump paired with your gas furnace), you can drastically reduce your carbon footprint and take advantage of Enbridge energy rebates, all while keeping your home perfectly comfortable year-round.
