Air Conditioning Maintenance FAQs


AC service valves are fittings on the refrigerant line that allow technicians to test the air conditioner’s pressure and charge the unit (add refrigerant). Only certified technicians (EPA 608 certification) can work with various refrigerants.

The refrigerant type for your air conditioner can be found in at least one of three places. Check the manufacturer’s plate on the AC. Check for a label on the condenser. Check near the air handler. 

If your AC says R-22, you have the old, phased-out refrigerant. If you see R-410a, you have the phasing-out refrigerant. Newer AC models may use R-32 or R-454b, while R-134a and R-513a are primarily for commercial air conditioners and chillers. 

If you have an older air conditioner, the R-22 is still serviceable if the technician has it in stock. However, it can be challenging to find. A certified technician can also service those with R-410a refrigerant, which is still available on the market, although the EPA plans to phase it out in new air conditioners in 2025. 

No matter what refrigerant your AC uses, the law specifies that only certified technicians (EPA 608 certification) can handle it, including servicing and charging your AC.

I needed our heater fixed and they were able to make it happen the same day. Andrew came out, was thorough in his diagnosis & explanation, and repaired our heater. I appreciate the service and am thrilled it was able to be done at the time…

We had Troy from Action Plumbing help us today with an outside faucet issue and he did a great job. He was fast acting, considerate, and offered some ideas for use to pursue in the spring with warmer weather. Thanks Troy!

Water heater went out overnight. Gave them a call at 7 am and they were at the house by 9. Highly satisfied. This is the third time I have used Action (2 plumbing, 1 electrical) and they have always done a great job. Pricing is competitive/fair…
