Frequently Asked Questions: Key West AC & Refrigeration Service

Are your technicians certified?
Yes. Our technicians are EPA certified and have completed the standard EPA courses required to work on residential and commercial systems. We work on almost all makes and models of air conditioners, including Trane, Carrier, Ruud, Rheem, Mitsubishi, Hoshizaki, Lennox, and Goodman. The one exception is window units, we don't service those.
How long do AC units last in Key West, FL?
In Key West, most AC systems last between 8 and 12 years, a bit shorter than the mainland average. Constant salt air, humidity, and heavy year-round use put extra strain on units out here. Regular AC maintenance makes a real difference in how long your system holds up.
Why is my AC not cooling my Key West home properly?
Common culprits include a clogged filter, low refrigerant, a worn capacitor, or corrosion from the salt air affecting your system's components. If your AC is running but the house still feels warm, it's worth having a tech take a look before it turns into a bigger issue.
What refrigerants are you licensed to work with?
We're licensed and qualified to work with a range of refrigerants, including R-454B, R-32, R-410A, R134a, R-404A, R407C. These chemicals are necessary in our field but harmful to the environment if not handled properly, so we recover all refrigerant using certified methods and deliver it to a refrigerant recycling plant.
