What Customers Say

“We recently had our furnace and air conditioning replaced by Mr. Furnace. And what a wonderful experience!!
Jeremy allayed any of our concerns by making a top notch presentation of their services. He was so patient in providing great details on how the HVAC works and different options available. His presentation left us no doubt in our mind that Mr. Furnace is the right choice for heating and cooling for us.

Jay and Josh, the installers, spent the whole day installing the infrastructure in a very deliberate, professional and clean manner. They laid out cloth in my unfinished basement to keep it clean! This shows the level of detail and care they provided during the installation. After the installation, they walked me through the basic maintenance and troubleshooting tips. They installed a WiFi enabled Thermostat which I was able to configure in no time. Josh was very kind to show me the way it needed to be installed and was very patient in explaining the operation.

If you need the job done by a company that stands behind it, just call Mr. Furnace. They will take care of everything.
Thanks so much, Jeremy, Josh, Jay, Josh in the call centre and all the wonderful folk that make Mr. Furnace GREAT!!!!!”

“We had a new furnace and A/C installed recently and Mr. Furnace was great. Christopher was very informative and was able to get a team to install our units within 2 days which was greatly appreciated as our A/C unit quit on us in over 40 degree heat. The installers were fantastic and had the job done in 1 day!! Thank you!”

Frequently Asked Questions

If your furnace is between 8 to 15 years old, you should be planning to replace it. Regular furnace maintenance can help prolong the life of your furnace. There is also some variance between different makes and models, which is why we offer free in-home assessments if you’re unsure.

The best time to install your furnace is before you need it. We recommend scheduling an appointment for your furnace in the fall before you switch your furnace on. That way we can assess your furnace for any necessary maintenance or repairs, or a full replacement. A preemptive assessment helps ensure your furnace will keep you warm all winter long.

We take every precaution to keep your home clean and damage-free when installing your new furnace. That said, we encourage you to remove all unnecessary items from your furnace room and to clear a path through your home. This makes the installation process more efficient for us and prevents damage to your belongings.

For an individual furnace, the estimated installation time is 4 to 6 hours. For furnace and air conditioning packages, the estimated installation time is 6 to 10 hours. How long installation takes will also vary depending on what package you choose and whether your furnace accessories also need to be replaced.

Different packages come with different accessories, which will influence the cost and the installation time of your new furnace. The cost and installation time will both increase for Premier and Optimum packages because we replace all accessories, including your ductwork and venting. Basic packages have a shorter installation time and reduced cost as we reuse these accessories.
