"Great. They contacted me right away. It wasn't an emergency but Iti was cold, so they still came first thing on the first business day. The technician explained what he was doing and why the prior repair done by somebody else probably failed. The rate was reasonable. It's been a couple of days and it seems the furnace is working, so everything good so far."

"knowledgeable, professional, prompt and courteous, highly recommend, came out the first day, repaired the next, if hvac issues arise again they will be the ones I call"

"Global Comfort installed a full HVAC system in my home; 7 new runs for air, new AC unit, new furnace and a new Nest thermostat, all electrical needs. Rudy and his team are respectful, efficient, punctual, competitive in pricing. Rudy walked me through running the system for its first time and explained all the stuff for a brand new system in a house that never had AC. I'm very thankful for the work they did. Highly recommend because their customer service is top notch."

"Jack did a great job and also explained how often the service should be completed based off of the design of our old fireplace."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"These guys are just excellent! I made a few mistakes before I got lucky to find New Millennium HVAC. They were professional from the beginning to the end. Jose did a thorough job, cleaning the dryer vent. It was not a straightforward issue and I was afraid that we’d have to open the wall to cure the blockage. However, Jose was able to fix it. He’s an experienced professional excellent at his job, trustworthy and overall great to deal with. I’m a happy customer for years now and will rely on these guys for any HVAC related issues."
