REME Air Purifier Special
Guardian Air™ doesn’t need the pollutants to travel to the air handler for UV treatment of filtration. Guardian Air™ is proactive and send ionized aggressive advanced oxidizers into the room to destroy the pollutants at the source, in the air or on surfaces, before they can reach your family, clients or employees.
" Great service from these guys. Jose came out to fix the a/c at about 9pm. He was very nice and very informative about why the air was not cooling. He had everything with him that he needed to fix the unit. Our landlord could not be reached to approve the fix that night, and Jose even offered to let us borrow a window unit from his personal home! Now that is customer service! Highly recommended! "

I contacted Quan Air and Joe Vallejo contacted me back and we set up an appointment so he could come out and look at it and advise me of my problem.Well Joe did just that and much more.He informed me step by step on what he was doing and even showed me where the problem was and I have never had a tech do that.This shows me that Joe is a very informative Tech and knows his job and he enjoys talking to people.If I ever have any problems Joe will be the first I contact.Quality service and good price.Great Job Joe.These are the type of Individuals that need to be recognized by their supervisors.

I would definitely recommend this company to my friends and use them again if need be. Darrin called me back immediately, was punctual, and my A/C was up and running before long. Great customer service and very professional. Thank you very much for your great service.

I called on Thursday @ 4:40 pm Joe called me immediately informed me he was out of town, but he would come by later which was better for us due to working late hours. Joe came out within 30 minutes a/c was cooling. Joe gave my husband tips on what to do if other issues arise with a/c

Linus Baer2024-12-03 Thomas was our servicing representative from Quan Air Conditioning and Heating. He was very professional courteous and knowledgeable. He did a great job and I would highly recommend this company for your HVAC needs. Gorman Warren2024-12-03 QuanAir was very professional. They provided multiple quotes for us to choose from and answered all our questions to assist in our decision on which AC system to buy. The installation team arrived when promised and communicated progress during the day. The install went very well and they stayed late into the evening to make sure everything was working correctly. They are also going to apply for the CPS Rebate for us, while other companies were going to leave that for us to do. We are very pleased with the entire experience and would highly recommend them. Needra Fulk2024-12-03 My unit was under warranty and they called and handled all paperwork with manufacturer. They had one person handle my case so I knew who to speak with each time. They installed and left my house clean. Would highly recommend this business!Google rating score: 5.0 of 5, based on 265 reviews
