Air Conditioner Inspection – Recommended once a year, before the start of summer, particularly if your system doesn’t seem cold enough.
Service Includes: Check system pressures; Inspect air conditioner condenser & radiator cooling fan operation; Inspect all air conditioner components for wear, leaks & proper operation; Evacuate & recharge system if needed. (Application of leak detection dye, if air conditioner system leak is suspected.)
Why: If your system isn’t running properly and is low on refrigerant, not attending to it promptly could lead to more costly repairs. There’s also the danger of leaky systems releasing R-134a refrigerant into the atmosphere.
