I have a mini split in my lanai that needs service. It was installed about 6 years ago and cools and heats perfectly except now it has started to hum intermittently, sometimes hours after the unit has been turned off. I've had one what I believe to be an outrageous estimate to replace the pump. Has anyone had experience with companies servicing these units and can give me a recommendation so I can get another estimate? Thanks for any advice.

Obviously the place it was purchased but sounds like you probably already tried that company. Unfortunately we live in a “throw away world” where it’s easier and many times less costly to replace instead of repair. I would try any company that sells and installed one. Good luck.

It is most likely that you have a bad capacitor. The part retails for 18.00 or so. I have replaced these myself. It is simple. You should pay a service call and whatever they charge for the capacitor.

Call during business hours for a non priority service call. It should cost approximately 150.00

It sounds like you may need a new condensate drain pump located in the inside unit. The pump will run even after the unit is turned off. You can buy one online for about $250, but you would probably need an HVAC technician to install it.

I recommend that you call Kalos for service, 352-243-0799. They installed my Mitsubishi about a year ago and I trust them for service.

I took my pump off and let gravity do the work.

OP, that sounds like a good idea to stop the humming noise, if you can drain the condensate line to the outside and either remove or disconnect the pump.

I had issues with my mini split also and found Daniels heating and A/C to be very good. They are authorized Mitsubishi dealer located near Inverness. They do many jobs in The Villages. Saved me $$ compared to the others.

My Mitsubishi mini split, installed a few years ago by Munns, has a 10 year parts and labor warranty, including the condensate pump. In case you haven't checked, perhaps you are still covered by a warranty?

Apparently, the pump is not a Mitsubishi part and does not have the same 10 year warranty. This according to Munns.

Thanks everyone. I knew I could get good info on this site.
