"This was our first experience using Wighton’s and it won’t be the last. Aaron was very professional and very nice to work with. Our air conditioner stopped working and he was able to fix it and did some maintenance work on the unit also. He also pointed out that we needed to replace the air filter which services our hvac system, which we were grateful that he did because we had never had it changed out with a new one and it was long overdue. We signed up for their maintenance program so that our ac/heating will be inspected and maintained on a regular basis. We are very happy with his work and highly recommend Wighton’s!"

"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."
