Is furnace maintenance necessary? Why do I need a tune-up?
Furnace maintenance is an important part of preparing for fall and winter.
Getting ready for the chillier months (not to mention the downright frozen ones) means making sure your home’s heating system is ready to run at top quality to keep you comfortable from autumn until April.
A tune-up is essential because it allows our HVAC technicians to check for any issues with core components of your furnace – heat exchanger, igniter and pilot lights, burners, gas valve, thermostat, flame sensor, draft inducer motor, pressure switch, blower motor, and return air filter.
Any issues that may hinder your furnace’s performance can then be addressed, ensuring there are no interruptions to your home comfort throughout the colder months.
The proactive nature of furnace maintenance also means you can avoid nasty, expensive, middle-of-the-night repairs during a classic Canadian cold snap, giving you peace of mind all winter long.
Will furnace maintenance save me money?
Furnace maintenance can help you identify any potential problems with your home’s heating system before they cause a breakdown, which means you’ll avoid the cost of any future repairs that may have resulted from letting the problem persist.
These potential savings are a main reason it’s a good idea to get a furnace tune-up in the late summer or early fall months: act now so you don’t have to pay more later.
Will maintenance improve my furnace’s performance over the winter?
Yes, a furnace tune-up can help ensure your furnace runs at peak performance throughout the winter months.
M&K’s HVAC technicians will look for any potential problems with the main parts of your furnace, allowing them to proactively repair them before they cause a major issue when you need your home heating system the most.

“I recently had an Air Conditioner and Furnace installed by M&K. I called around and talked with several companies, they have the best warranty and were the most knowledgeable when it came to answering my questions. Everything was installed perfectly and up to code in a timely manner. Very happy with the system and service!“
