We had a good experience with Air Quality Dunrite. They were able to offer a good replacement unit for our AC at a better price than others I had contacted. Thank you for the fast and professional service.

This company has been in our family for years. Thank you Marcello for your expertise and knowledge. You were able to acquire and have my mom's A/C installed on time and by professional techs who were very pleasant. . I highly recommend your team to anyone looking for an A/C or furnace. Thank you for your time and patience. We will definitely recommend you to our family and friends.

Air Quality Dunrite was highly recommended and they proved their worth and reliability. They efficiently and on a timely basis installed or I should say change over my electric baseboard heating to a highly efficient gas furnace and central AC. I thought that the installation of ducts would create a mess and a lot of ceiling and wall damage in my house. Was I disappointed. Vacuuming was constantly done during the project and the laying of floor runners/mats protected my hardwood flooring. I was amazed by the cleanliness and carefulness the workers took in my home. Pricewise I was satisfied and I highly recommend them. All workers wore their PPE during the completion of the Job.

Recently had a new furnace and Hepa filter installed. The installation was flawless, neat and clean and on time as scheduled. I would highly recommend AC Dunrite for all your heating and cool needs.

Very pleasant experience dealing with this company. Our furnace quit recently and when they diagnosed the problem we determined that it did not make much sense to pay for a very expensive repair to an out of warranty 10 year old furnace. They provided a couple of small heaters to keep us from freezing over the weekend until we could arrange for the new furnace install. The technicians were great and after arriving early in the morning we were back up and running within a few hours. A special thanks to the General Manager Marcello Patricca who went out of his way to give us the best possible price and quick scheduling of the job..much appreciated. I highly recommend this company for your home heating or cooling requirements.

Regular maintenance is important for anything with mechanical components and your HVAC system is no different. Without proper air conditioner and furnace maintenance, you risk complicated and costly repairs and a shortened lifespan.

FAQs about HVAC

What are the most common furnace problems?

Some furnace issues occur more frequently than others. While some require an emergency HVAC service, others can be easily fixed by yourself. Here are the most common furnace issues you should watch out for.

  • Thermostat problems that lead to fan or comfort level issues.
  • Dirty filters reduce airflow and affect home comfort.
  • Furnaces that produce squeaking noise indicate a slipped or worn blower belt.
  • Frequent cycling of the furnace indicates a clogged filter, bad thermostat setting, and improper airflow.
  • A furnace that does not heat enough is caused by a clogged filter or incorrect size for the space.
  • A cracked heat exchanger can affect the ability of the furnace to produce heat and allow carbon monoxide to seep into your home.
When is it time to replace my old furnace?

If your furnace is old and is not functioning well, then it is time to call an expert HVAC technician for a new furnace installation. Watch out for the signs that you need to replace your old furnace.

  • When your furnace is more than 15 years old
  • Uneven heat distribution in your house
  • Frequent malfunction despite being fixed by a professional Toronto furnace repair technician
  • When weird noises become unrepairable
  • The furnace is leaking gas
  • High energy cost
How often do I need to schedule HVAC maintenance?

Expert HVAC technicians recommend booking an HVAC maintenance in the spring before the summer season and in the fall before the winter months. Regular maintenance helps prevent serious problems during the seasons when you need them the most. Replacing the filters regularly ensures that your HVAC system is operating at top efficiency, as well as good indoor quality.
