"I had Maynor do my HVAC last week. Not only did I get the best price but the professionalism of this company and its representatives is second to none. Mike came out and did a very thorough explanation of my options. He clearly knew what he was talking about from experience. He knew what I needed for top notch comfort. The installers came in and were very professional. They showed up on time and made great use of time as to not hold me up longer than necessary. I love my new system and I can’t say enough positive things about these folks. They stand behind their work. You won’t be disappointed!"

"From the moment we inquired about services to job completion, we had a great experience working with Air Quality Concepts for our HVAC air duct and dryer vent cleaning. The owner Charles was incredibly prompt with communication and took the time to answer all our questions about the cleaning process prior to scheduling. We were so impressed by how personable, hard-working, thorough, and efficient our technicians Austin and Michael were when they cleaned our two HVAC systems. They were very attentive to the issues we have been having with our indoor air quality as we navigate mold remediation and health concerns. The company’s customer care was genuine and so appreciated, and the cost of services was very reasonable. We already feel more comfortable in our home knowing we are breathing cleaner air! I highly recommend Air Quality Concepts if you are looking to improve the air quality of your home!"

"This was an unusual situation. In talking to Phil, the owner; and Randy, the former owner, I was treated very fairly when I brought my situation to their attention. Though it took awhile to coordinate communications between them and myself (busy schedules), once they surveyed the situation, they were very responsive. Their supervisor for system installation, Perry Allen, reviewed my HVAC system and came up with a great solution to the problem. He returned with all the required supplies and worked hard to ensure I had the proper solution. Perry was absolutely terrific (his colleague too). He not only wanted to fix the problem, but to do it the best way.
I'm very pleased with Gand M Service Company and would highly recommend them for new HVAC systems as well as service contracts.

"Jeff came out at 11:00 at night to help my family sleep comfortably and not be miserable. He checked everything to find the problem and found it and repaired it. Without his kindness and honesty we would not be comfortable on our home now. Thank you Jeff. I recommend him above all for any hvac issues."

Heating and Air Conditioning FAQs, answered by experts

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
