Common questions

My Midea unit heats but will not cool. What is wrong in Hyde Park?

That points to the four-way reversing valve sticking or its solenoid coil failing. It can often be freed and the coil replaced without opening the sealed system.

Do you charge a callout fee?

A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.

Is a compressor replacement guaranteed?

Yes. Replacements are done with a system flush and new drier, and both part and workmanship are warranted, provided the original cause of failure is corrected.

How fast can you get to me?

Emergency callouts are dispatched to the next available technician, with the arrival window confirmed by SMS when the vehicle leaves.
