  Alejandro showed up on time, was able to fix the issue promptly and was friendly.
Alex HVAC, gave me better pricing and explained the issue better than the previous technician I had come out. I’d recommend them for HVAC needs.

Alex installed a brand new Furnace and Humidifier in my townhome. He not only did a great job with the installation, but also provided me with exceptional customer service. When I called Alex to ask him how to work the furnance because I wasn't available during the actual installation, he went out of his way and drove all the way back to my home just to show me! I will use Alex for any of my future Heating and Cooling needs, and highly recommend him!

Alex HVAC is timely, responsive, and communicative. I couldn't be happier with their service. They installed a new system throughout my house, responded to two minor issues, and it works perfectly. Thank you

 5/5

Alex is absolutely amazing! I had 2 different companies come out to look at my HVAC system and both told me they couldn’t even service my A/C because of the way it is set up. They did know I needed a new one because they could tell it was from the 80s! All of them quoted me the price of a nice used car! Both companies had to call their managers for them to explain how my A/C is even set up! Alex came out and took a look at it and right away knew everything these 3 companies had to call managers for. All of his employees are professional and kind! Alex will go out of his way to help anyone and won’t over charge you. He’s a kind, professional, and honest man!

 5/5

Alex HVAC Service LLC provides exceptional service for HVAC maintenance, repair and replacement. Five stars. Alex HVAC Service was recommended by a friend. I have since used them through two moves. They kept my system working for years until it could no longer be safely repaired and installed a new HVAC system, beating competitors prices. They also replaced my hot water heater. Most recently they have maintained a traditional and a split Air/Heat system. I trust Alex HVAC Service to provide expert advice on my systems. They respond to issues and get me scheduled on their calendar promptly. Alex HVAC Service provides estimates and invoices as well as photos and a detailed explanation of work that is needed. I highly recommend Alex HVAC Service LLC.
