I worked with David Renault at McCullough to install two mini-split units in a garage apartment and do other energy efficiency modifications under the Austin Energy rebate program. I was left in the lurch by another company two days before the rebate period ended, and someone recommended I contact David. It was late July, a very busy time in the HVAC business, but David was able to design the system and give me a quote in enough time to sign a contract and not lose the rebates. They installed the system very quickly and efficiently, leaving everything very tidy. They handled all the paperwork with the city and also with a subcontractor who replaced all the windows in the unit. David kept in touch with me and answered all my many questions. The tenant has been thrilled with the changes and I'm an incredibly happy customer. I'd highly recommend McCullough and David.
