Help Improve Your AC Unit with Liquid SEER

When Liquid SEER is applied by our certified installers to the outdoor coil, AKA that "radiator looking thing on my A/C unit", it boosts the ability of the coil to do its job. The coil is designed to remove heat, and Liquid SEER enhances the heat transfer process already happening in your coil. Applying Liquid SEER helps your coil use less energy to create more cooling capacity (known as BTUs or tonnage.) Liquid SEER's innovative technology is able to optimize your unit's ability to remove heat, helping it achieve more using less energy so that your current 3-ton unit can perform more like a 3.5-ton unit.

Liquid SEER is the black coating that delivers big green benefits for your home and the planet.

Thank you to the Arizona Comfort Specialists team that came to my house and replaced our 27-year-old AC unit. Starting off, we had a great experience with Josias walking the site and figuring out the quote. His professionalism and warm personality were fantastic to interact with. I explained my needs and what we were looking for, and we were able to find the right product at the right price for our home. A week later Bryan and Tim came to the house and started bright and early on the dismantling of our old unit. After removing the old unit, they found that the compressor could not fit through our back gate, so they ordered a mobile crane to make sure it was done right without damaging the new compressor or our house. When they were done with the new air handler install, I asked a few clarifying questions. They both took time and care to make sure that I understood everything and felt comfortable with the result, phenomenal customer service! Once everything was installed, they cleaned up by vacuuming and wiping down the stair rails and trim, along with vacuuming the carpet. They didn't cut corners and did a thorough job! I would recommend the Arizona Comfort Team to anyone, they are a great company and they hire great people to do great work!

Had a great experience with Arizona Comfort Specialists! Josias was awesome during my initial quote and was very professional and knowledgeable about the Bosch systems (which was what I was most interested in). He noticed that my supply duct was a bit undersized for the unit and included an upsizing in the quote to allow the unit to have a better static pressure. They had great prices compared to my other quotes and a great warranty on the unit as well! On install day Bryan and I believe Tim? were a fantastic install team, they did a lot of hard work in the attic running the new flex ducts for the system. The unit had a bit of a dent on the louvers but they were able to come out that same day and replace the panel ASAP and the unit is looking great. Looking forward to a nice cool summer coming up!

I've been working in all sectors of construction for 27 years. From residential to major commercial construction. I've crossed paths with a hell of a lot of HVAC Contractors in those years. It's safe to say, I've never worked with a HVAC company more professional than Arizona Comfort Specialists. Not only are their entire team (from office staff to field techs) a pleasure to work with but their owner (John) is both extremely knowledgeable and very gracious with his time when it comes to figuring out the intricacies of Air Conditioning (be it new install, retrofit, upgrade or servicing) as a whole. ACS are consummate professionals.

AZ Comfort Specialists did what they said, showed up on time, charged a fair price that didn’t exceed the estimate, performed excellent installation and clean-up! Josias was knowledgeable, friendly and professional. He communicates effectively and I felt like I understood exactly what needed to be done AND what didn't need to be done. EXCELLENT!!!
