Why Customers Stay With Us

The Same Team. The Same Standards. Every Time.

We’ve been servicing homes across the GTA, Hamilton, and Niagara for over 30 years. What keeps customers coming back isn’t a loyalty program — it’s knowing exactly what to expect when they call.
01

The Tech Who Shows Up Is Accountable

Every technician on an APAS job is an APAS employee — licensed, insured, and responsible for the work they do. There’s no handoff to a subcontractor you’ve never met. If something needs following up, you call the same number and reach the same team. That’s how it’s worked since 1991.

02

We Service Where You Live

Whether you’re in Etobicoke, Hamilton, Grimsby, St. Catharines, or Fort Erie, your call goes to a team that knows your area, keeps parts in stock for the systems common to your region, and can actually get to you when something goes wrong.
03

We'll Tell You When It's Not Worth Fixing

Replacing a furnace or heat pump is a significant decision. We walk you through when repair still makes financial sense, what the real cost of waiting looks like, and what equipment is actually worth the investment for your situation.

The team at APlus Air are always professional, prompt, and responsive. They have provided excellent maintenance and repairs to our generator over many years and I will continue to work with them and refer them.

Replaced an aging air conditioning system, furnace and hot water tank with new Trane AC and furnace and a tankless water heater. And oh yes a new thermostat and electronic air cleaner. Irfan was excellent at outlining the products we needed and explaining the differences. He was always prompt, courteous, and open to any questions. The installation was handled very well by three of the best installers we have had into the house. They were careful not to damage anything and took care to keep the house clean even though the rain continued most of the day. Their professional attitude and experience made a huge job go smoothly. We could not be happier with the A Plus team and of course we love our new Trane products. If I had to give them a grade, well, it would have to be a solid A Plus!

Had annual furnace service from A Plus Air Systems this week. This year it is Tashi's turn. He did an excellent job: arrived within agreed time frame; called ahead inform his ETA; did detailed checkup, testing and cleaning of the furnace, and passed me useful information on furnace filter selection. All are good and satisfied with the service. I have been using the service from A Plus Air Systems for over 10 years. Good experience outweighs not so good ones by a wide margin.

A Plus Air Systems have been servicing our air systems for over 20 years. For the past 20 years or so Aziz Koya has been our Service Specialist. Initially we just had our furnace and air conditioning system looked after but about 15 years ago we got an electronic air filter system from A Plus then about 5 years ago we had A Plus replace our hot water tank with a tankless water heater. Through it all our service from A Plus has been superb. While our prime contact has always been Aziz, he is obviously well supported by A Plus and particularly by Steven Abraham. The work done has always been timely, thorough, well executed and fairly priced. We have never felt pressured to buy anything; when something has been deficient, Aziz and Steven have presented the alternatives to us and allowed us to make our decision. We highly recommend Aziz, Steven and A Plus! Recently we moved into an apartment. On September 22nd, 2026 Daniel from A Plus installed our new through the wall AC unit. He arrived on time, did a superb job of quickly and efficiently installing the unit inside and out and cleaned up after. We highly recommend A Plus and Daniel! They are worth every penny!

We recently had a new heat pump and tankless water heater installed by A Plus Air Systems, and we couldn’t be happier with the experience. They offered us a very reasonable price with a **3-year, no-interest financing option**, which made the investment much more manageable for our family. A Plus Air Systems is a great family-run business, with **Said Mosmer and Rashid Popal** leading an excellent team. Everyone we dealt with, including **Mohammed and Noah**, was professional, knowledgeable, friendly, and committed to doing a great job. It’s refreshing to deal with a company that genuinely cares about its customers and takes pride in its work. I will definitely be calling A Plus Air Systems for all of our future HVAC needs. **Thanks to Said, Rashid, Mohammed, Noah, and the entire A Plus Air Systems team! Highly recommended!**

Farid & Moza installed a Trane furnace in our home. They are an amazing team! Their expertise was very apparent & impressive. They were punctual, respectful of home cleanliness & removed all waste material. Their determination & focus to get the job done stands out. They went the extra mile to ensure we were 100% satisfied. The allowable space we had was challenging & they made it work without breaking drywall, like some other quotes had recommended. They vented to the side of the house versus the front which was more challenging but more appealing. I recommend this team for all jobs especially complicated ones
