Great air conditioner installation by Raj and team. Raj came and gave us a quote and the next day we had a brand new air conditioning unit. Would highly recommend them.

Rajpaul and his team were very courteous and professional. They made sure all connections were up-to-code for the Heat Pump. They answered and explained all the steps thoroughly (especially to a person who has no electric knowledge). Will call them again to install a tankless water heater.

Had an 18 year old water heater that needed replacement. Contacted a few HVAC companies before settling on GN Air Solution. Mr. Singh was able to answer all my concerns in a very honest and thorough way. The tankless unit was installed professionally. And as an added bonus, despite my insistence on paying for it, he complementarily sorted out some minor issue I was having with my fireplace and furnace.

We needed help with our furnace that stopped working multiple times. A few people from different companies came to check but were not able to fix the problem properly. Finally Rajpal came to check the issue and was able to fix it. He was professional, and knowledgeable and was able to pin point where the issue lied. Very very happy with the service! Definitely recommend them!

This is a highly trustworthy and cost-effective company. Mr. Rajpal and his team possess extensive knowledge and expertise in their field. Despite my furnace being very old and located in a tight space, they replaced our furnace and completed the job exceptionally well and offered some of the best rates in the city.

I recently had a new Lennox furnace installed, and I’m extremely satisfied with the entire experience. Rajpal and his team did an outstanding job from start to finish. They were professional, punctual, and very knowledgeable. The installation was done smoothly and efficiently, and they took the time to explain everything clearly, including how to operate and maintain the system. They also made sure the workspace was clean before leaving, which I really appreciated. Overall, it was a hassle-free experience with high-quality workmanship. I highly recommend Rajpal and his team to anyone looking for reliable and professional HVAC services.

I had been wanting to install a whole-house water softener for a while and after doing my research, I decided to go ahead with GN Air Solution -and I’m really glad I did. From start to finish, the experience was smooth and professional. The team showed up fully prepared with everything they needed. What really impressed me was that they didn’t just install the water softener itself; they also installed a dedicated power outlet to properly power the unit, which shows they think ahead and come ready for the full job. Honest pricing, clean work, and a team that clearly knows what they’re doing. Highly recommend GN Air Solution.

Consider equipment age, repair history, comfort, efficiency, parts availability and current repair cost.

Correct sizing depends on the property, insulation, windows, layout and heating and cooling load. Correct sizing is essential for comfort, efficiency and equipment life.
