Best heating and air conditioning pros near Round Rock, TX

"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

"I have always used indoor comfort experts for all of my air conditioning needs. The staff is extremely knowledgeable and friendly to work with. Seth has many years in the trade and it shows through his work. I highly recommend this company!!"

"It was scorching hot outside and our AC went out. We immediately called Petrocelli Services and they sent out a professional Technician to diagnose. It turned out we needed a new AC unit after 16 years. The staff was considerate of cost, time and made it extremely easy for me to understand the next steps. The open line of communication was amazing and kept me involved and provided me with detailed order form. Staff also played a huge roll in educating us on maintenance when caring for our new product. I will definitely call them again and refer them to my friends and family!"

"I find them to be very honest. They don't try to make you upgrade. They sell you a little contract each year. They do a clean out of your equipment and a checkout of your equipment in the spring and then again prior to the winter. I have just found them to be real down to Earth. They have told me that my unit is better built than anything that I could buy today. They said as long as I could get parts for this one they suggest that, even though it is not as energy efficient as some of the new ones, it is older, but it is built better and it will last longer. It is very hard to find anyone in that business to tell you that because they are in business to sell new systems."

"Thomas was excellent about responding to our request for an HVAC system bid, and when chosen, they were able to schedule our installation within a couple of days. They asked our needs and made recommendations for the right equipment for our home. The crew was efficient, polite, and neat. I could not ask for more!"

"Matt came to my house the same day that I called and was very prompt. He fixed my AC unit right away and showed me the faulty parts. I am very pleased with him and his service."

"Great company. I recommend them."

"Excellent installation, diagnosis, and customer service. Highly recommend."

"Jose worked with me on the options to fix the hvac. Ended up replacing the whole system at a competitive price. Installation was done nicely and they explained clearly what was done."
