Our Services


Our licensed gas technicians in Toronto are available for emergency repairs and replacements. Trust our team when looking to bring the warmth back to your home—the team that puts your safety and comfort first.


We set the highest standard for air conditioning repair and all cooling services and installations. Air conditioner installers are notorious for bad practices, but not our team. Each Toronto air conditioning repair technician of ours must meet a minimum of 4000 hours of field experience before working in the field by themselves, as required the College of Trades.


Our hydronic experts understand the complexity of boilers and all the necessary auxiliary components required to make each one operate safely and efficiently. We'll bring back the heat in your Toronto business or residence while protecting homeowners from carbon monoxide leakages from older boilers and performing the proper calibration/setup required for higher-end boilers.

Gas fireplaces provide a calming atmosphere and a source of warmth in pur living space. However, they lack some key safety components found in other gas appliances that put them ata higher risk of creating hazards.

Bad practices will leave your system contaminated, incorrectly charged and full of leaks. Worse is that these home or commercial HVAC problems can stay hidden for years before they wreck noticeable havoc on your system.

Our technicians go through in-depth training to protect you from these risks. Our team are also skilled with air conditioner maintenance. We ensure proper superheat and subcool of your system to maximise performance and longevity.

Tank Heater Repair, Maintenance & Installation

Our team handles all types of tank water heater repairs and installations, and works on all major brands. You can learn more about these services on our tank water heater services page.


Tankless Water Heater Repair, Maintenance & Installation

Throw any knowledge you have about tank style water heaters out the window when approaching tankless systems. They are completely two different animals.

Tankless water heater repairs require the expertise that specialise with them.

Our repair techs understand GPM, raise temperature, delta-T and all technicalities that are unique to tankless water heaters.

Likewise, water heater installation skills are not translatable to tankless. Our tankless install teams are manufacturer trained and certified to install these systems. Our installs also come with a 12-year Parts and Labour Warranty.

Tankless maintenance is a must. Calcium carbonate clogs the heat exchanger and internal piping of the system. Annual flushing is necessary to prevent system inefficiency and premature failure.

We’re your experts in tankless water heater repairs. You can find details on our tankless water heater service page, including information on a maintenance plan that will keep your water heating system working well, longer.


Fireplace Repair, Maintenance & Installation

We provide gas fireplace repair in Toronto, along with every other service your system needs to operate safely. Regular maintenance is important when it comes to safe operation. Learn more on our gas fireplace service page.

Our techs are familiar with all brands and specialize with Rheem, Keeprite, Goodman and American Standard.

The Accuserv Difference—How Our Furnace Techs Stand Apart

We take the hiring and training of our maintenance and repair techs who will carry our name very seriously. Here are some of the ways we protect our reputation for quality by keeping our techs at the top of their game:

Continued Education

Learning doesn’t stop once technicians leave school. Many companies throw their techs into the field without sufficient training and supervision. As a result, this leads to misdiagnosed furnaces and higher repair bills. We aim to be the best furnace repair service in Toronto. Our heating and cooling technicians are continually being trained on the latest and best practices in diagnosing and servicing furnaces.
