I had an amazing experience with McCullough. I had two different companies tell me I needed to replace my 9yr old HVAC system. When Brandon came to check it out, he reassured me that I don't need a new system. He replaced the part that needed to be replaced and it's working fine now. He was very communicative throughout the whole process and explained everything in a way that made sense. I felt a billion times better after talking with him. I will only use this company moving forward for all my HVAC needs.

Sam went above and beyond and stayed extra long to resolve every issue we encountered in repairing the AC unit. Affable guy. Would recommend.

A motor went out, so it was serious; without AC for two days. Blake from McCullough did a great job: polite, capable, informative, thorough, wasted no time.

Our A/C went out while it was 100+ degrees and we needed it fixed fast. We called that evening and they sent Mike out the next morning. Mike promptly made the repairs (had all the parts on his truck) and walked me through everything. Very professional, responsive and thorough. Highly recommend!

Mike visited my house and was a total gentleman. He expertly reviewed my system and fixed the issue I had, with extreme professionalism. Great experience all around!
