This is the best AC Company in Georgetown. They are fast and reliable, the prices are extremely reasonable, and the technicians are the nicest in the business. I appreciate how knowledgeable they are and how quickly they can solve your issues. I’ve had two emergencies over the last year, including one that caused a water leak in my attic and they were able to come within the same day (weekday) or on a Sunday to root cause and fix. Jensen is extremely knowledgeable and such a nice person, transparent with pricing. You never feel like you’re being taken advantage of like with other companies. Highly recommend.

Great service above and beyond best describes Jensen and his team. If you are needing assistance with your home I highly recommend the team at McCullough Heating and Air Conditioning in Georgetown. While nobody wants to have to replace their HVAC, this service is top notch. Jensen made improvements to the house and Mike and Bryce are true professionals. Love this team!

Great experience overall. Everyone was extremely nice and professional, upfront with what was going to happen and how long it would take. The technicians showed up on time, made sure that covers were added to not damage or dirty the carpet. The install was fast. Started just after 8am, cleaned up and finished by 3pm. All in all a great experience even though we didn't want to purchase a new unit yet they certainly made the process worry free and were very helpful. Certainly a company to recommend to others.
