"I’ve been a customer for years. Coolray is the best!"

"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

"Good."

"Cool Air Mechanical LLC delivered exceptional service with our water heater installation! From the moment we scheduled the appointment, their team was professional, punctual, and incredibly knowledgeable. They assessed our needs thoroughly and guided us to the perfect unit for our home. Installation was seamless—efficient, clean, and done with care. We appreciated the technicians’ attention to detail and their willingness to explain everything clearly. What truly stood out was their commitment to customer satisfaction. They even followed up to ensure everything was running perfectly! It’s rare to find a company that combines technical expertise with genuine courtesy. Highly recommend Cool Air Mechanical for anyone in need of top-notch HVAC or plumbing services. They’ve earned our trust and future business!"

"Blake did a wonderful job. He was so polite and respectful. He asked "when do you want them", I said "yesterday". He then ran to Home Depot to get the taller toilets I wanted. He also gave me some pointers on another matter. Thumbs up!!"

"I am VERY disappointed in my experience, even though it started out positively. Justin, the sales rep, was very helpful and I paid my deposit right after Christmas. However the customer service since it was installed has been less than optimal. The system has now shut down 3 times. I paid almost $12K for it. Este's says that the manufacturer has to send someone out to upgrade the computer. No one can tell me when that will be. Unacceptable."

"We had a full HVAC system replacement for both floors of our home, and we are truly grateful for the service we received from Weather Masters. From the beginning, the owner was understanding of our situation and worked with us on the pricing in a way that no other company was willing to do. He adjusted the cost significantly — almost as if we were paying cash — which meant so much to our family during a stressful time. The installation was done professionally and efficiently, and the team was respectful and organized throughout the entire process. It’s rare to find a company that combines professionalism with genuine care for their customers. We truly appreciate Weather Masters and highly recommend them. Thank you again for helping our family."

"The guys from Economy Heating and Air helped us with a emergency situation with our old furnace, including a replacement of the unit with a new heat pump. They were the only company I called that could come out immediately to look at the problem. Overall, I felt very comfortable with their HVAC knowledge. They answered all of my questions and left the jobsite clean after their work. I highly recommend."

"Trend Mechanical did an amazing job. They were very transparent, and communication throughout the whole process was great. They were affordable and timely compared to the competition. I highly recommend them."

"They found nothing wrong with it and just changed the filter. They responded quickly, was very respectful, and just wanted to make sure everything was okay. I can't rate them high enough and I would highly recommend them. I would definitely hire them again."
