Delta T Heating & Cooling is an excellent choice for anyone looking for honest, high-quality HVAC work in Brampton and the surrounding area. Delta T Heating & Cooling is easily one of the best HVAC companies I have dealt with. From the first contact, the response was fast and professional, and every appointment time given was accurate. Lomesh took the time to explain what my equipment options were and all the strengths and weaknesses of each brand instead of rushing through the visit or trying to sell extras I did not need, which really built trust. He really took care to ensure I got the right package for my needs. What stood out most was the combination of technical skill and honesty. The work was done neatly and to a very high standard, with everything tested and double-checked before they left. Pricing was straightforward and reasonable with no surprises, which is rare in this industry. You can tell they care about long-term relationships, not quick sales. This is a fully licensed, insured, family-owned local company that has been serving Brampton and the GTHA since 2011, and the experience shows in how smoothly they handle both heating and cooling jobs. They offer everything from furnace and heat pump service to AC installs, water heating, gas piping, and even indoor air quality solutions, so it is very convenient to have one trusted contractor for it all. If you want reliable work, fair pricing, and a contractor who actually shows up and stands behind the job, Delta T Heating & Cooling is the one to call. Highly recommended.

Would highly recommend this company! We have used them a few times and found them reliable, honest, punctual and reasonably priced. When our air conditioner gave out during the heat wave in late June 2025, Lomesh was unavailable due to scheduled vacation. My husband was adamant that we would wait for his return and so happy we did. The 25 year old unit was replaced and working beautifully with 7 hours of dedicated work on the same day by Lomesh and staff. So happy to recommend this company.

I was having ongoing issues with my air conditioner not working properly and after searching on the internet decided to call Delta T Heating & Cooling Inc. on a Monday morning (during the heat wave!). Lomesh responded right away and was at my house that very afternoon. He even texted me a few minutes after the scheduled appointment time to let me know he was on his way — a thoughtful touch that I truly appreciated. Lomesh was very professional, knowledgeable, and courteous. He quickly diagnosed the issue with the unit, clearly explained what he was doing, and had everything up and running again within the hour! The price was also very reasonable, which was such a relief. I was so relieved and grateful to finally find someone who not only knew what they were doing but also genuinely wanted to help. Thank you so much, Lomesh! I highly recommend Delta T Heating & Cooling Inc. — top-notch service with heart. With gratitude, Susan

I’ve called Lomesh on serval occasions. I continue to call him due to having trust in his honesty and decent pricing. Lomesh is straight forward and explains things in simple terms for those like me who don’t understand HVCAC. He is punctual and also responds quickly.

My fireplace suddenly stopped working. I did some research and came across this company, which had good reviews from past customers. I was able to get in touch with Lomesh who came to my house, diagnosed the problem and timely resolved the issue. He not only fixed the issue, he also educated me on proper maintenance to avoid similar issues in the future. The service charges were also quite reasonable. I would definitely recommend this company!
