I have worked with Gosalair in two projects. And one repair work. The founder owner Kesar Singh is prompt, technical, fully hands-on, sincere, quick to reply with quote, explain, courteous and execute the job quickly. He is pricing is reasonable, lower than anyone with comparable experience and skill. I recommend him fully to anyone.

Mr. Kesar Singh did a wonderful job to replace the Thermostat for my house today and also cleaned the air filter as well. The air filter had never been clean since it installed back to 2010; I am sure it will save money later this year. Thank you for his professional advice. He is highly recommended to others. My furnace is working well.

Got bids from several contractors and despite some of the poor review on here I trusted my gut and went with Gosal.

Great experience, they installed a new 4 ton AC unit and new furnace for me.
