"I reached out to Angi’s to find a HVAC company to help with my AC that was blowing hot air in the summer. I got super lucky when I found MSR Heating and Cooling. They arrived on time and assessed my situation. I appreciated the time they took to explain the issue in ways I understood as well as recommend the best option for me. The estimate quote was fair and there were no surprise expenses to repair my unit. I can’t thank the owner, Moises enough for a job well done. His professionalism, knowledge and skills are reflected in the quality of work performed. I would highly recommend this company for your next repair."

"After having a very bad experience with another HVAC company, I used them and quickly saw how the other HVAC company was over charging. I found my technician to be very knowledgeable, hardworking and honest. He repaired one AC unit and replaced the other. Would definitely recommend!"

"This was hands down the best most professional service company I have ever used! I highly recommend this service to anyone who is considering air duct cleaning. I had been told that my vents were fine by the service that installed our new heating and air system. But I still noticed a great deal of dust in the house. Plus my husband was coughing all the time. When the team came out to clean I was completely amazed at all the lint and dust they removed from the vents. It was probably a garbage bag full. Can't believe we were breathing that! All I can say is if you have never had this service, please do. They also found some black mold upstairs and treated it. Very affordable too! Thank you to this amazing team of professionals!"
