We address routine operating issues where appropriate to help support consistent heating and efficient furnace performance through the cold season.

If we find anything that needs follow-up, we explain what we found and recommend the appropriate next step.

For many Toronto homeowners, scheduling furnace maintenance once a year before the heating season is a practical routine. The right timing can also depend on your furnace age, usage and service history.

Is It Time for Furnace Maintenance?

If your furnace is running normally but it has been a year or more since its last service, it may be time to schedule maintenance. A furnace tune-up before Toronto’s heating season can also help address routine concerns before winter demand increases.

01

Before the Heating Season

Schedule a furnace tune-up before regular winter use begins.

02

If It Has Been a Year or More

Annual furnace maintenance helps keep seasonal service on track.

03

When Performance Starts to Change

If your furnace still runs but feels different, mention it when booking.

Furnace Maintenance vs Furnace Repair

Maintenance

When Maintenance Still Makes Sense

01

Your furnace is operating, but seasonal or annual service is due.

02

Heating still works, but performance feels less consistent than usual.

03

You want the system checked before heavier winter use.

04

There is no active fault that clearly requires diagnostic repair.

Repair

When It’s More Than Maintenance

01

The problem is repeatable and is actively affecting your heating.

02

The furnace is shutting down, failing to run normally or showing a clear fault.

03

A noise, smell or operating change needs diagnosis rather than routine upkeep.

04

A previous maintenance visit identified an issue that now needs corrective work.

The most honest HVAC company in the GTA!

Jack came over, was able to offer a reasonable solution to my home temperature issues.
When on site, realized that half of the job was not necessary. Let me know and didn’t charge me for needless work.

After the adjustment, I had overpaid - MAS refunded the difference on their own initiative.
David H Toronto
I recently installed heating, air conditioning, a water heater, and a water softener, all thanks to the recommendations from sales representative Shawn.

He was extremely professional and provided fair pricing tailored to my house.

Shawn promptly addressed any questions I had before and after installation.
Miranda Z North York
My furnace stopped working in a Sat morning, then I start looking for solutions.

My friend refered Norman to me and he came to check for me 2 hours later found out that the heat exchanger was gone.

Very fast response and great service, thumbs up! Will definitely recommend Norman to my friends
Jackie C Richmond Hill
We want to replace our water tank to an energy saving tankless water heater and sought assistance from this company. Shawn, our advisor, was exceptionally patient and thorough. He took the time to explain all possible options and detail with us, ensuring he fully understood our needs and preferences as customers. When it came time for the installation, David, the technician, was incredibly professional. He arrived promptly, worked efficiently, and maintained a high level of cleanliness throughout the process. His attention to detail and meticulous approach ensured everything was installed perfectly. I have nothing but good things to say. 
Cherry P Scarborough
Very happy with their service. Our furnace broke down on the weekend, and they booked to come the next day for a replacement.
The rep (Shawn) on the phone was very knowledgeable. His quote was a good price and it came with labour cost all inclusive, so no hidden fees.
When they got here, the technicians are highly skilled, hard working, and took the time to explain and answer our many questions. I am recommending these guys to my friends.

Furnace Maintenance FAQs

For many homeowners, annual furnace maintenance before the heating season is a practical schedule. The appropriate interval can vary depending on the furnace manufacturer’s recommendations, equipment age, usage and previous service history.

A maintenance visit focuses on the condition and operation of an operating furnace, routine maintenance needs and concerns that may require further attention. The exact work depends on your equipment and its condition.

Many homeowners schedule furnace maintenance before regular winter heating demand begins. Booking before the coldest weather gives you an opportunity to address routine maintenance needs while the furnace is still operating.

No. Maintenance cannot guarantee that a component will never fail. Its value is that the furnace can be inspected and maintained under planned conditions, giving you an opportunity to identify developing concerns and routine maintenance needs before an unexpected breakdown.

If we identify an issue that requires diagnosis or repair, we explain the concern and the recommended next step. Repair work is handled separately from the routine maintenance visit.

A furnace tune-up is scheduled preventive service for a furnace that is operating. Furnace repair is for an active problem such as no heat, failure to start, cold air, unusual noises or another malfunction that requires diagnosis.

If your furnace is already experiencing one of these problems, visit our furnace repair service.

Homeowners can perform basic upkeep such as monitoring the filter and keeping vents unobstructed. Professional inspection, diagnosis and work involving the furnace itself should be handled by a qualified HVAC technician.

For routine homeowner care, see our furnace maintenance tips.
