"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."

"Very impressed -- more than I initially planned on spending to simply have my air vents cleaned, but when I saw how much they planned to do and how involved the process was (much more than merely cleaning the vents) - it was well worth the money. Very knowledgeable and professional - highly recommend."
