Furnace Maintenance for the St. Catharines & Niagara Area

What Sets Us Apart

To help keep you and your family safe every furnace maintenance visit includes a safety check. Our technicians will check your furnace and ensure that it is not producing carbon monoxide. Carbon monoxide is a deadly gas that has no taste, smell, or colour.

To help ensure we don’t miss anything all of our expert technicians follow a standard maintenance checklist. We will ensure that the combustion chamber and heat exchanger are operational and functioning normally, check your pilot safety timer or flame sensor, and replace your thermocouple if it has begun to wear out. We will also check the motor, thermostat, and safety controls to ensure that they are clean and properly adjusted.

Our excellent customer service and team of experts is what sets Mr. Furnace apart. We aren’t satisfied until you are satisfied, which is why we work hard to ensure that every interaction you have with us is a good one.

If any parts need to be replaced we only choose high-quality parts that you can count on so that you can rest assured that you, and your family, can remain warm, safe, and comfortable. To help ensure your furnace continues to run at peak efficiency all furnace maintenance visits include a thorough inspection, a top-notch clean, and lubrication of any moving parts.

What Customers Say

“We’ve been happy customers of Mr. Furnace for years, for annual service and maintenance. This evening our boiler stopped working so we placed a service call. Real people answer the phones at Mr Furnace (no automated system). The gentleman I spoke to was very friendly and helpful. He told me a service person could come tonight, and provided an accurate time estimate. They called back to tell me when the technician was on his way. The technician Mark arrived and was extremely professional and kind. He fixed the boiler and got our heat back on, which was so greatly appreciated on this cold night. Despite the fact that it was late, he provided fantastic service with a smile. Thank you again Mr. Furnace!

We had Mr. Furnace back last week to do our annual preventive maintenance. As usual, the service was professional and courteous, from the office staff who called to book the appointment and notify us when the technician was on route, to the technician himself. The technician was Mark again, and he completed the servicing efficiently and with courtesy. We are so happy with the service from Mr. Furnace!”

“There must be something in the name Brian/Bryan! A very nice young man, on time, highly efficient and very professional came to my home this morning for regular maintenance service. Thanks Mr. Furnace for sending the best. We’re very confident our home will be cozy and warm all winter.”

Frequently Asked Questions

Furnace repair is an appointment made to fix a specific problem with your furnace. Furnace maintenance, on the other hand, is an opportunity to make sure that your furnace unit is running as well as possible. It’s a tune-up that gives you the peace of mind of knowing your furnace is performing well.

You should schedule furnace maintenance at least once per year. Annual furnace maintenance gives you an opportunity to have your furnace evaluated by an expert to check for any issues that could cause large repairs or breakdowns in the future. A regularly maintained furnace will run more efficiently and reliably.

Without regular furnace maintenance, your unit is more vulnerable to costly repairs or breakdowns. Furnace maintenance is like a physical for your furnace. It’s a chance for an expert to make sure that everything is running smoothly and to detect any issues. A well-maintained furnace will run better and longer.
