Review of Certified Heating and Air Conditioning

This review has been a long time coming. I cannot say enough about the staff at Certified Heating and Air Conditioning!!! They are absolutely A-MAZING! I've had excellent service from Techs Brittany, Frank and Diego! It's def a reflection of their boss man B who cares about his company and clients! I bought a house a couple of years ago and I've had multiple companies come out to address issues with my fancy dual pump furnace. The other companies could not figure out the issues with my equipment until along came Brittany. Brittany was tenacious and figured out the issue. She then gave me a very reasonable quote and did the work with a labor guarantee! All of this over one of the HOTTEST days of the year when I'm sure they were in high demand. Brittany then explained their maintenance program... it's easy peasy! You sign up for a nominal monthly fee and they come out to service your unit. They even send you text reminders to schedule your appointments when it's time. BEST INVESTMENT EVER! Fast forward to today... My furnace recently started having issues during this very cold winter... and their service is the best! Brittany and Frank came out quickly and assisted me with getting the heat going! Brittany then replaced my thermostat the very next day... I can't say enough good things about Brittany.. she's an absolute lifesaver! So if you're looking for a GREAT company to assist with your heating and air conditioning needs... look no further!
