"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."

"I HIGHLY RECOMMEND HVAC Superior Solutions Inc!! They came over to diagnose my AC problem on very short notice. I decided to get a whole new system and they took great care in all the details and worked overtime to get the job completed. I am very satisfied with the new system and with the great customer service."

"we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years. They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr.
We are very happy.

"Quickly responded to my ac issue. They advised me of the issue and recommended contacting the company who installed the unit as it might still be under warranty. Even though the repair (new circuit board) is expensive I appreciated their honesty in helping me with advice on the potential warranty with the original installer. You don't normally see this kind of honesty in companies today. I'd highly recommend them."
