"After extensive research about the HVAC products and the descriptions about the complexity of installation for our home, we selected Wighton's. The bid was lower than the competition. They started the day after we agreed to the bid and completed the project in 5 consecutive days. We realized very quickly that professional installation was as important as the 2 complete HVAC systems. Everything went very well and we felt we received the best in every way."

"I not only had an old furnace replaced but also had whole house air conditioning added. Very professional family business. Their estimate beat out two other HVAC businesses here in Lompoc⠦⠦ one of them by thousands of dollars. It paid to get three estimates. Daniel was easy to work with and honest. One of the other HVAC businesses in Lompoc is interested in selling you all kinds of stuff that increased his estimate by thousands of dollars. I highly recommend Ace Heating & AC."
