Heating, Air Conditioning, Fridge, HVAC/a/c


My a/c serviceman says our residential 3 ton a/c compressor and evaporator coils need to be cleaned once a year. Can I do this myself with my vacuum cleaner hose? Or with anything else?

You can clean the outside condenser coils by turning the 220 breaker off and hosing the coils from inside the unit towards the outside.
I don't know what you have for inside evaporator cooling coil? If you keep a clean air filter in the unit you most likely don't need to clean the coil?
Are you having  a problem with cooling???
