  • I would recommend this business

I trust these guys... unlike the previous guys who let my A/C system fall into disrepair. They are courteous, explained the issues with my system and charged a reasonable price to clean the coils and seal the unit.

Customer Testimonials

I highly recommend this man!!! He saved us from a miserable 88degrees in our small town house. He came out at 7pm!!! It took him 10-15 min to arrive at our house after calling him. He fixed our ac problem in a fair and reasonable price. Thank you!!! We can sleep in comfort tonight.

I had a new system installed in April, my home has been more comfortable AND my electric bills have been lower than any time during the previous 3 years.

Clay is a class act. He truly cares more about his customers than money. There are several times that he has saved me money by providing options rather than telling me what would be the most expensive as the thing I need to do. I DEFINITELY recommend Clay and the Cool Dude AC.

Monica was my initial contact with this company, and I cannot say enough good things about her. I was certain my house was going to burn down as it smelled just awful. She was so caring, and immediately put me at ease. She contacted Clay, he called me right back, and they had someone come over that very day to take a look at my unit. My unit was very old, and the motor had burned out. Clay gave me several options, and there was no pressure whatsoever.

I chose to replace my antique unit with a new heat pump, and I couldn't be happier. They even went the extra mile and brought over a temporary motor so I would be cool until I had my new unit installed. So....from my call with the marvelous Monica to the soft hum of my new a/c unit, I am one happy customer. I will happily recommend Cool Dude Air Conditioning and Heating to everyone.

Perfect! Service was excellent, he was punctual but best of all responsive, honest and to the point. I already had an idea of how much it may cost if the issue was what he had thought of before he even got to the house. I called and within 45 minutes he was at my home and fixed the issue in 10 minutes. Clay is an outstanding person, fair, honest and gets the job done, quickly. He will not upsell you if not needed. Best service I have received in a very long time!!

Great service! They are honest, show up on time, and are extremely professional. They clearly explain your situation and what they can do to fix the problem, keeping cost in mind. I can't say enough great things about this company!

Could not be more satisfied with service received from Cool Dude Air Conditioning. We had to replace our AC unit and they did a great job. Very affordable compare to other companies.

From Our Website

Most people don't think about their HVAC unit until its broken, which is too late. Here are five helpful warning signs that your unit may need servicing by a certified heating and cooling technician. Evaporation coils: They may be clogged, if there clogged with dirt the system will not cool properly and you'll be hot. Leaking refrigerant: Your technician will have to run a test to locate the source of the leak and fix it for your system to start operating at its full capacity. Leaking ducts: If you have a leak in your duct, the cold air that should be keeping you cool is spilling into the attic, between walls, or outside your home.
