  • I had a great experience with GTA Heating and Air. After our previous tankless water heater only lasted a few days, we were really stressed. I called and spoke with Mr. Ali, and within minutes he and his partner arrived to assess the situation. They quickly identified the issue and replaced the unit efficiently. The service was fast, professional, and very reassuring during a frustrating situation. Thank you, Mr. Ali, for your excellent service. I highly recommend GTA Heating and Air!

  • We purchased a new Furnace from Ali Foghani (GTA Heating & Air) and its the best advice Ali gave us instead of fixing parts of an already faulty old furnace. He came within promised time with his colleague Alex, they detected the exact problem and gave us the correct advice. The prices were not high (justified for his service & installation) compared to others, service was excellent, Ali didn't charge me extra. We have warranty & labor charge coverage with our new Furnace unit. Highly recommend Ali and his team. We will reach out to him for further services in future. Thank you Mr Ali Foghani for your excellent customer service, kindness and honesty (which is rare these days),we truly appreciate it!

  • Simply excellent! Prompt to come to assess our issue, so reactive at keeping in touch via Texts, get the diagnostic done and replaced the whole furnace within the same day on a Sunday! As we say, companies which strive are the one Customer Satisfaction focus, GTA Heating & Air strives and deserves to be known! Thx Ali.

  • Many thanks to Ali and Alex for excellent service and great job. They replaced heat pump in my condo. Punctual, responsible, experienced, knowledgeable, and their quote is very reasonable. I am happy with the result and recommend them to everyone if you look for perfect balance of quality, time and price.

  • I purchased a Carrier brand furnace from GTA Heating and Air an found the prices to be competitive and the service to be professional. It's working great on this cold winter. Ali F. and his team at GTA Heating and Air are great. Highly recommended.

  • Ali and Alex were very friendly, helpful, reliable and professional. They showed up ahead of schedule on a Saturday, quickly diagnosed the issue with my heater and efficiently completed required fixes and installations. Even more impressive was the fact they returned to resolve an issue the next day and didn’t charge me extra. I was so impressed by their service and immediately referred them to several home owners and contractors in my network. Keep up the great work gents and I’ll definitely be contacting you again for future servicing and maintenance.

    Veliko O.

  • I had a problem with my boiler for 4 days and I try to call some Heating companies they came and checked the boiler but they were unable to repair the problem. However, my friend recommended me to call GTA Heating and Air. Ali and his helper came and fine the problem and fix it on the same day. Based on what I experienced for my boiler I definitely recommend GTA Heating and Air.
