I contacted The Cool Dude AC & Heating for a quote because I had been told by another AC company that we needed a new condenser (outside unit). Grace, the technician, was super helpful. She came out that same day to look at the unit. In the end, she was able to repair it and saved us a major expense. She took her time and was kind enough to see if the new part she installed would work for a few days before charging us. Really great customer service!

Grace was Great! She found the problem we thought possibly could be the issue making the unit stall on occasion but the other supposedly top-notch group that came out did nothing but bump the thermostat that made it come on; they did no other troubleshooting on the unit saying it was obsolete and if there was a leak they couldn't even buy Freon for it but still charged me a fee. I asked them could you at least clean the drain for the fee and said they would when I decided to use them to replace unit. Grace was thorough with her checks saying there were no leaks and Freon level is right where it needed to be.

She did some extra stuff to ensure the unit continues it's longevity as long as possible and gave us hints on maintenance and keeping rooms cool. She even replaced my intake filter without asking or charging. We will definitely use Cool Dude AC and Heating in the future.

I have used Cool Dude for years and cannot say enough about how happy I was to finally find and quality company that is not only prompt and professional but also cares about doing a great job! Clay has had to troubleshoot both HVAC systems and has done a great job each and every time. Grace came out for the first time this NY Eve to replace the thermostat so we would have heat on NYE. She was in and out in no time! They are hands down the best!

I first used this company when I moved in for a tune-up, but recently called for an AC repair and they had someone out within an hour and a half. She fixed the issue quickly, and told me what the long-term solution would be. Definitely calling them back for the long term fix! Highly recommended. Service: A/C system repair

The "Cool Dude" came out to our home to fix our AC, as it wasn't cooling properly. Within an hour he had fixed it and was pleasurable and sociable while working. He educated us on what the issue was and very reasonable. We will be recommending him to others in need. Thank you Clay!

I have had Cool Dude replace a 3 ton ac unit as well as repair a 2 ton unit. I have found that they are very honest and ethical in all aspects of their business. You cannot find a better service provider for all your AC and heating needs. I wanted to especially thank Grace for saving the day today as we are going to have out of town company and desperately needed to have our upstairs unit repaired. She arrived the same day and got our unit back up and running! I cannot recommend this company enough. Thank you very much!

Cool Dude A/C met all my needs. My number one priority was a good dependable brand at a fair price. I got that as well as prompt service, top notch installation and a company that is going to stand behind their product and workmanship. Grace was there every step of the way making sure the job was to my liking. Thank you Grace and Clay for meeting my expectations and more. Thank you to Hector and your team for a clean install and every member of the company was completely professional. I would highly recommend Cool Dude A/C.

We have done business with The Cool Dude for over 20 years. Every repair or replacement has been professional, efficient and correct. He has never had to return for a 'redo' or to correct ANY work done. In addition, his people are as professional and reliable as he is. We have been repeatedly impressed with all of his people. They work rain or shine; on time, honest, and great value. If you want it done right the first time, call Clay, The Cool Dude. By the way, in an industry that is usually male dominated, Clay has one of the best workers we have ever met. Grace is awesome! She makes me proud.

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.

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.
Mary Helm
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!
Nino Lansang
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!!
Tricia Albracht
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.

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.

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.
Therilyn Del Rosario
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.
