We’ve always been with McCullough for our AC inspections. They have always been a great company to help us when we’re in need. We recently needed a brand new AC install due to our old one (13 years old) leaking. We went through 3 quotes with other companies, and Charles gave us the best deal for us. We had two great install technicians (Bryan and Justin) work all day to throughly finish the job, and even finding a manufacturer parts defect in the process. They ended up staying all the way till 8pm to walk through new thermostat and show us how to use it. Charles even came back to install some cover piping on the condenser unit to help prevent weather damage. Absolutely a great experience for us. We will continue to do business with McCullough for a long time.
