AIR MAX HVACR LLC We take great pride in our experience, expertise, quality, and customer service that we provide to meet our consumer's needs. In order to understand expectations of our customers, we take great care to work and communicate with everyone in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"I have used this company twice. I first gave them a call over the summer for an emergency central AC issue. They were able to quickly come out, ID the problem and fix it the same day for a very reasonable price. They did so well that I called them again a couple of weeks ago when I tried to flick my furnace on for the first time and nothing happened. When it rains, it pours, right? Once again, Air Max was able to quickly respond and found a simple sensor problem and the whole visit took less than an hour and cost me under $100. I feel like I would have been out at least a grand calling another company. I TRUST these guys!"

"Henry was professional and thorough. He went out his was to see that our heat was restored on the coldest day of the year. You can spend a significant amount of money dealing with the big HVAC advertisers in our market but why pay for their ads when you really want competent service? This company provided me everything I expected in a repair."

"Horrible. Paid for annual maintenance contract on four units. Called when one unit wasn’t working and never heard back from them. After many attempts finally talked to office worker and scheduled appointment. I called the morning of the scheduled service to confirm timeframe and was assured they would show. When it was time for them to arrive received a call they had to reschedule. Very rude office support that could care less. Asked several times for the owner to contact me and still has not. Do yourself a favor and find another company."

FAQs for air conditioning projects in Hanover, MD

You can identify your system's refrigerant type by examining the data plate or label often located on the outdoor condensing unit. Look for "R-22" or "HCFC-22" in the specifications. 

Manufacturing date provides another clue—systems produced before 2010 often use R-22, while newer units utilize alternative refrigerants. If the label is missing or unclear, a qualified HVAC technician can determine your refrigerant type during a service inspection.

Federal regulations prohibit the purchase and handling of R-22 refrigerant without proper EPA certification. These restrictions exist because R-22 contributes to ozone depletion when released into the atmosphere and requires specialized handling procedures. 

Additionally, improper refrigerant charging can damage your system and create safety hazards. Professional technicians have the training, equipment, and legal authorization to properly diagnose, repair, and recharge your system.

Air conditioning systems require approximately two to four pounds of R-22 per ton of cooling capacity, with three pounds per ton being the average. For example, a 3-ton system needs about nine pounds of refrigerant for a complete charge. However, the exact amount varies by manufacturer, model, and system configuration. A professional technician will determine the precise charge required for your specific equipment.

While technically possible to retrofit some R-22 systems to use alternative refrigerants, these conversions require substantial modifications to system components and are rarely cost-effective. The compressor, expansion valve, and sometimes the entire coil system would need replacement or adaptation. Most homeowners find that investing in a complete system upgrade provides better long-term value and performance than attempting conversion of aging equipment.

Though new production of R-22 ended in 2020, reclaimed and recycled supplies remain available but are steadily decreasing. The EPA's final phaseout deadline extends to 2030, but practical availability may become severely limited well before that date. As supplies continue to diminish, expect prices to rise accordingly. Homeowners with R-22 systems should begin planning for eventual system replacement as part of their long-term home maintenance strategy.
