Eric was exceptional. Today he reset my complicated new wifi-connected thermostat that had gone offline and taken my AC with it, and then taught me how to do that myself. He spent time checking all possible causes for the outage, patiently explained the process, answered my questions, and provided a solution: surge protectors to prevent power surges or brief outages from knocking out my thermostat and HVAC again. He also took time to show me features I’d been unaware of so I can make the best use of my new HVAC system. He also checked output and temperatures at each vent and was able to cool down the warmer rooms. He was courteous, knowledgeable, and kind, and left me feeling reassured of McCullough’s excellent service and moral support.

Just finished my project and had a great experience overall. I shopped around with all local, reputable companies and McCullough really blew everyone out of the water. My project manager Peter was knowledgeable and had a no pressure, educational approach. He was the only sales rep that took the time to fully explain the Austin Energy rebate program. By leveraging the program, I was able to get a new dual stage HVAC unit, attic insulation AND brand new duct work for less money than the next best priced proposal that only included a new unit. The rebate program also offers 0% interest financing for 10 years, which was by far the best financing offer from all the bids I received. All of the install technicians were very professional and courteous. Jimmy the supervisor ensured everything was up to their high standards of quality and inspection ready. You will be hard pressed to find another company in Austin that is not private equity owned, has a no pressure/professional sales process and high quality installation for a great price.
