I recently purchased a Trane furnace and heat pump from Home Depot, and A Plus Air Systems assisted me with the installation. I can honestly say that my experience has been truly amazing from start to finish. It all began with the research and decision-making process. Said took the time to explain all the available options in simple, easy-to-understand language, which helped me make an informed decision considering the significant investment involved in purchasing a new furnace and heating/cooling system. Thank you, Said, for your excellent service and guidance. My great experience didn’t end there. It continued through the entire installation process with the experienced technicians, Mohammed and Jalal. They completed the installation of both the furnace and heat pump seamlessly and professionally. They were extremely knowledgeable and took the time to explain every little detail I was curious about. What impressed me most was their professionalism, patience, and dedication throughout the installation. Despite the intensity of the work, Mohammed and Jalal remained courteous, focused, and committed to putting the customer first. Their attention to detail and workmanship were outstanding. A big thank you to Said, Mohammed, and Jalal for providing such excellent, professional, and impressive service. You made what could have been a stressful and complicated process a very smooth and positive experience. I would strongly recommend A Plus Air Systems, and especially Said, Mohammed, and Jalal, to anyone looking for furnace, heat pump, or HVAC installation services. Excellent work and excellent customer service — very well done!

Good morning. As usual everything is well till I make the payment in full. Company decided a specific date & time for the installation. I agreed to that date & time. Installation was at 8 am. Got call from driver at 7.59am that he is delayed by 45 minutes. Fine. Now 8.15 got call from office with vague request that truck has a problem & installer will be there as on as possible. So company expect us to sit whole day waiting for installer after purchasing something more $10,000. I called at 9.15 enquired about my installation. Answer from Office manager is ON THE WAY !!! I had a frustration & ask who is responsible for this delay as I scheduled my other appointments around it. Office manager ask me in most rude & unprofessional manner “ WHAT I EXPECT HER TO DO??? Really ???? I send the sales person (Mr Elias) a note about this incident. Till today he never responded to me either by email or text message. I will but recommend this company.

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 A Plus Air Team

20+ Licensed Technicians. One Standard of Work.

Every technician on an APAS job is an APAS employee. Not a subcontractor. Not a seasonal hire. Our team is TSSA-certified, ESA-compliant, and accountable for every job under our name. From your first call to the final sign-off.
