Gosal installed a new furnace in our hallway closet and we also ended up adding an AC unit in the back yard for the summer time. Price was reasonable compared to the big companies and the whole installation was finished in two days. Service: Installation

We had purchased a Rannai free-standing heater to replace an existing 96-year-old heater. We called several HVAC companies to get an estimate on the cost to have the old heater removed and the Rannai installed. First problem that we ran into was that it was too small of a job (usually made obvious by their $3000 minimum for any on-site work). Others would only install heaters that we purchased from them.

We finally found Gosal Heating and Air Conditioning. They did not feel a need to send a sales-person to our house, just asked for a photo of the old and new heaters. Upon receipt of the pictures they replied with a very reasonable quote for installation. They fit their installation day into our schedule, arrived at the appointed time, discussed the installation options, got the job done in five hours, and cleaned up when they were done. Excellent work. Highly recommended.

We replaced the furnace and Installed new A/C. Kesar is a great communicator from the beginning till the end. I'm very satisfied with his services. Service: Installation

Kedar was extremely professional and completed the job well. No complaints. Explained everything thoroughly. Service: Installation

I needed to get my 55-year-old heater replaced and i looked at a lot of companies and interviewed several. I decided on Gosal Heating and Air Conditioning because of the cost and the honesty of the information received to make an educated decision on who i will hire. I am so glad i hired Gosal Heating and Air. I not only had my heater replaced but i also went with Air Conditioning. They installed in a timely manner and the installation went great.

I referred 3 people to Gosal Heating and they hired him also. All of us are happy with Gosal. I would not recommend going with anyone else. This is the company to do business with. I have another house and i will go with Gosal again when it is time to replace my system. I am extremely happy.
