Furnaces & Furnace Repair Services
A high-efficiency forced air furnace is the most cost-effective way to heat your home. As an experienced gas furnace contractor in Kitchener-Waterloo, we install, repair, and maintain all types of natural gas heating systems. When installed properly, a furnace runs reliably for 15-20 years, but wear and age eventually take their toll.
Two-stage furnaces are one of the more cost-effective options for natural gas heating. In the first stage, the gas valve opens fully to bring the heat exchanger to temperature. Once heated, the furnace kicks into the second stage, using much less gas to maintain temperature. Compared to single-stage furnaces, which cycle on and off at full power, two-stage units deliver more consistent heat with lower operating costs.
Whether you need a quick repair or a full system replacement, our TSSA-certified technicians diagnose accurately and fix it right the first time. We carry common parts on our trucks so most repairs are completed in a single visit.


Clean Installs, Done Right
When you're spending a few thousand dollars on a new heating system, it should look like it. Professional. Clean. The kind of install you can stand back and say, wow that looks great. Every furnace, boiler, and gas line we put in is built to that standard, because workmanship matters as much as the equipment.
Tidy line sets, square venting, labelled shutoffs, and neat sheet metal transitions are the details that separate a quality install from a rushed one. In Kitchener-Waterloo homes, your heating system usually sits in a mechanical room or utility space you see every week. It should look intentional, not improvised.
We take pride in leaving every job site cleaner than we found it. That's the Prolific Mechanical standard, and it's why our customers recommend us to their neighbours.
Make The Switch To Natural Gas
Whether you want to install a gas furnace, gas fireplace, gas boiler, or a gas barbeque, we handle the full conversion. Natural gas is more cost-effective than propane or oil, and modern high-efficiency gas appliances can reduce your heating costs by 20-30% compared to older systems.
Natural gas BBQs make grilling more reliable because the supply never runs out like a propane tank. Most BBQs today can be converted from propane to natural gas with a manufacturer conversion kit. Once the outdoor gas line is installed, you are good to grill year-round.
We also install gas lines for ranges, dryers, fireplaces, pool heaters, and garage unit heaters. All gas line work is performed by TSSA-licensed technicians and inspected to code.


Heating Your Water Supply
For endless hot water and longer system life, we install tankless water heaters and boilers. Traditional tank water heaters are best handled by a dedicated plumber, and we're happy to point you to trusted local options.
A tankless water heater heats water on demand, so you never run out of hot water. If your family takes long showers or needs multiple showers in a row, a tankless unit provides endless hot water. With proper maintenance, tankless units run reliably for about 15 years. We install Navien as our primary brand because their units consistently outperform competitors in reliability and carry an industry-leading warranty.
A boiler heats water in larger volumes for in-floor radiant heating or radiator systems. Boilers provide exceptionally even, comfortable heat and are common in older Kitchener-Waterloo homes. Our TSSA-certified technicians install, repair, and service all major boiler brands.

HEATING & NATURAL GAS FAQ
How much does furnace repair cost in Kitchener-Waterloo?
Common furnace repairs like igniter replacement or flame sensor cleaning typically cost $150-$400. More complex repairs involving blower motors, control boards, or heat exchangers may cost $400-$900. We provide a clear diagnosis and upfront pricing before any work begins. All estimates are free with no obligation.
How do I know if I need a furnace repair or replacement?
If your furnace is under 15 years old and the repair cost is less than 50% of a new unit, repair usually makes sense. If the furnace is over 15 years old, requires frequent repairs, or has a cracked heat exchanger, replacement with a high-efficiency model is typically the better investment. We give honest advice on which option makes more financial sense for your situation.
What brands of furnaces do you install and repair?
We install and repair all types of residential furnaces. Whether you have a high-efficiency condensing furnace, a mid-efficiency conventional model, or an older system, our TSSA-certified technicians have the training and parts access to service it.
Can you convert my home from oil or propane to natural gas?
Yes. We handle full fuel conversions including oil-to-gas, propane-to-gas, and electric-to-gas. This includes coordinating with Enbridge for the gas connection, installing the new equipment, decommissioning old tanks, and handling all TSSA permits and inspections. Many homeowners save 20-40% on annual heating costs after converting to natural gas.
Do you offer emergency heating service?
Yes. We offer 24 hour emergency service for heating failures, especially during the winter months. A furnace breakdown in a Kitchener-Waterloo winter is urgent, and we treat it that way. Call 519-729-1456 and we will prioritize your call.
