AC Repair

Our AC went out on the hottest day of the summer. CoolHVAC had a technician at our house within two hours. He diagnosed the issue quickly, explained everything clearly, and had it running again the same day. Incredible service.

Heating Installation

We replaced our 20-year-old furnace with a new high-efficiency system. The team was professional from the initial quote through installation. They even cleaned up better than when they arrived. Very fair pricing too.

Maintenance Plan

Been on their maintenance plan for three years now. They come out twice a year, tune everything up, and catch small issues before they become expensive problems. Peace of mind is worth every penny.

AC Installation

Got three quotes for a new central AC system. CoolHVAC was the most detailed in their assessment and competitively priced. The installation crew was on time, courteous, and finished in one day. Our energy bills dropped noticeably.

Emergency Heating Repair

Our heat stopped working on a Friday night in January. Called CoolHVAC and they had someone out within an hour. The tech was knowledgeable and fixed the issue fast. Can not say enough good things.

Ductwork

Had them replace old ductwork in our 1960s colonial. The difference in airflow and efficiency is remarkable. Every room actually gets to the temperature we set now. Should have done this years ago.

AC Repair

Good service overall. The technician was professional and fixed our AC compressor issue. Scheduling was easy and the price was fair. Only minor note is the service window was a bit wide, but they did call ahead.

Heat Pump Installation

Switched from oil heat to a heat pump system. CoolHVAC walked us through every option, helped us understand the rebates available, and completed the install with zero issues. Already saving on our utility bills.

Indoor Air Quality

Had them install a whole-home air purification system. The technician took time to explain how it works and showed us the filter schedule. Our allergies have improved significantly since the installation.

Commercial HVAC

We use CoolHVAC for our office building. They handle quarterly maintenance and any repairs that come up. Response times are fast, pricing is transparent, and the building stays comfortable year-round. Highly recommend for commercial clients.

Heating Repair

Furnace was making a terrible noise. The CoolHVAC tech identified a failing blower motor, had the part on his truck, and replaced it in under an hour. Fair price, no upselling, just honest work.

Full System Replacement

Replaced both our AC and furnace. The project manager kept us informed every step of the way. The crew was respectful of our home and the new system runs whisper-quiet. Best home improvement investment we have made.
