I was scheduled within a day after my new heat pump started making a loud rattling sound. The service person showed me the loose piece and tightened it while I watched. This came after a multi-day switch from oil heat, with new units, piping, controls, and final testing.

Our cooling system suddenly started making a terrible grinding noise on one of the hottest afternoons of the year. I shut it off immediately and called this company hoping for a quick fix. The technician arrived within hours, diagnosed a failing fan motor, and replaced it on the spot. The house is perfectly cool again, and the unit runs quieter than ever.

Our commercial print shop's air conditioning system was producing supply air at 68 degrees at the air handler but only 79 degrees at the supply registers in the production area — an 11-degree temperature rise across the duct run that was leaving our production floor 8 degrees warmer than our thermostat setpoint despite the system running continuously. The technician used a duct blaster test to identify three unsealed duct connections in the unconditioned attic above the production floor that were leaking 28% of the system's conditioned air into the attic space, sealed all three connections with mastic compound and foil tape, and the production floor reached the thermostat setpoint within 35 minutes of the repair being completed.

AC stopped working and I had no idea what to do. Called this company and the technician came out fast and got it fixed. Such a relief honestly.

We needed a new AC unit installed, and they came and got the job done in just one go. A clean job, neat wiring, and testing before leaving. This is the coolest our home has ever been.

We noticed our home wasn’t heating properly and figured something was wrong with the furnace. Their furnace repair service was fast and thorough they found the issue and fixed it the same day. Really appreciated the clear communication and fair pricing.

Totally satisfied and kind of amazed, to be honest! I needed someone to fix our furnace that was not blowing, and this company responded right away. The technician they sent was super thorough and clearly knew his stuff. The repair was done impressively, and I could not be happier with how it turned out.

Fast, thoughtful, and knew exactly what he was doing. The technician was super professional and made sure I understood what was going on during the repair. After everything was done, I even told him that I had never seen such quality work from other companies. We have been using this company for years, and their technicians’ skills are a big reason why we stick with them.

When my old furnace gave out, I reached out to this company for a replacement. They were incredibly professional throughout the process. The technician helped me choose the right furnace for my home size and budget. The installation was done efficiently, and my new furnace is working better than expected. I’m happy with the result and highly recommend them!
