"Worked with Tim - was looking for new HVAC system. He was honest and provided the best price for what you got (literally thousands of dollars cheaper from other options I was finding). Was very communicative and easy to work with. He made sure to educate you on the ins-and-outs of HVAC systems, and did not try to upsell you like other companies might do. He and Efficiency Air definitely got me as a new continued client."

"It was installed with a kink in the condensation hose and was not aware that it leaked under our hallway wood floor. This was June 2022. I paid to have a leak detection company come out and say the floor was OK. In August 2022, we ran HVAC for a couple of days during the heat wave and water came out of the HVAC unit, ruining our hallway wood floor. It is 10/29/2022 and we still have not heard from their office on how they are going to fix our floor."

"I had estimates from four HVAC companies. Hilo Aire speaks VOLUMES without any regrets. Everything from A to Z went beyond my expectations. The crews were so good that they took their time to inspect and install the cooling and heating systems. I’m truly IMPRESSED. Ask for Chad and/or Brett. KUDOS to them and the crews."
