Responsive and outstanding customer service. 24/7 service. McCullough Air conditioning installed a new air conditioning system and discovered a leak in the lines from the outside compressor to the inside. They spent all day fixing the line. I would definitely recommend McCullough

A bit delayed on this post, but that proves the company stuck in my mind as a very well run company. Ben gave me a very honest assessment on my A/C unit and the options I had. I chose a new unit. Then, only months later, Ben answered returned a call after 10pm on a holiday night in the mid Florida summer heat and showed up that same night so my baby and 2 year old would be able to sleep in the A/C (a user error fault, btw). Then he took the extra time to show me how to prevent what happened and did all that in the most happy and professional manner. Highly recommend this team.

We have used McCullough Air for years in our home, our rentals, and business from everything from replacing thermostat to replacing entire units. Ben McCullough is knowledgeable, efficient, and always accommodating when we were down. No high pressure sales just good ole honest information that will help keep your unit running smooth, your family comfortable all without robbing the bank. You don't stay in business for over 40 years doing people wrong in a small town where everybody knows your family name. Ben had big shoes to fill and he is doing an amazing job carrying on the family business!

The company replaced my 15 year old system. Price was about what I expected. They did offer a military discount which was amiable. The installation was not level as far as the exterior unit goes. The company did send someone back out to my residence to remedy it and they were complete in about 20 minutes. The gents were always kind and courteous.

I highly recommend this company. We called them and they came and diagnosed the problem. They were back the next day for the install and did a fabulous job. They were careful to keep the place clean and were very fast with the work they did. It was just before a holiday weekend and saved our weekend. I was very impressed with them. I would hire them again in a heartbeat.

I called and they were there same day. Had my new air conditioner installed within 24 hours. Their installers were professional and courteous. Even tolerated my two dogs with kindness. As a realtor, I have used them for many other clients and they always do a great job with no complaints! Thanks so much to the McCullough crew.

Polite, honest, and professional. Had it fixed in minutes. Another company recommended buying a new unit and said ours was toast. Clearly that was not the case.

Ben and his team were courteous and fast! I had AC within 1 day to last me until I had a new unit installed early the next day. Ben gave me honest advice and a good price. I strongly recommend McCullough AC! 5 stars!!

Such an outstanding and extremely professional company. Back in January my HVAC unit went out. I reached out to Ben McCullough. Ben responded within 30 minutes and was able to troubleshoot that my AC compressor was bad and that I would need a new unit. Unit was very old and needed upgraded and had prior issues that Ben was able to fix before to keep the unit running. Ben stated that they could have a new unit installed next day and I agreed to have them come the following morning at 9:00 am.
Ben’s crew arrived about 15 minutes early, two young guys forgot their names. Both gentlemen were extremely
