We recently had a new mini split system installed by McCullough, and so far, we're very impressed. From start to finish, the experience has been smooth and professional. There were 4 other highly rated companies that bid for the job but McCullough was the best in price and product. Jensen Sexton, was very thorough in explaining to us what we need to adequately cool the detached garage, the process of the installation, and the tax credit rebate that's available. Installation was handled by a knowledgeable and courteous team who completed the job on time and with minimal disruption. They took the time to explain the features, maintenance tips, and remote options, which I really appreciated. Overall, I highly recommend McCullough Heating and AC.
