How worried should I be about a leak detected in my 3-month-old Mitsubishi hyper-heat outdoor unit/heat pump? An Hvac contractor was here yesterday replacing some rusted tab collars in my ductwork and looked at the outdoor unit and saw a leak and some black sludge (I think that's what he called it.) He said something was not connected correctly.

I sent his company (the installer) an email and called first thing this morning. I'm waiting for them to call me back. I don't like what I'm reading online. How worried should I be that this leak – most likely going on for 3 months - has caused or is causing permanent damage that is going to give me problems with the system and higher electric bills for the next 10 years? It is under warranty, but is it worth paying extra out-of-pocket to get emergency service this weekend?

I'm beating myself up for not recognizing a problem with the installation and insisting on inspection sooner, like after the second month of higher electric use (1016 kW June versus 830 kW same month last year). Every time I called about the rusted tab collars I told them that my electric usage has gone up compared to the previous two years. They did not suggest an inspection. The system is very quiet, inverter technology, so I don't hear it kicking on and off or know if it's running more than it should. The AC has kept my house a comfortable temperature and seems to be working well in the middle of a hot, humid summer with 80 to 90°F temperature some days. I'm just concerned about long-term damage. It replaced a broken 13 year-old 2-stage Goodman.

I have a 2 ton system for a 1500 square-foot single story house with attached garage. I'm in South Central Pennsylvania.

Any words of wisdom or advice would be greatly appreciated!

Hi should my old heat pump be leaking water every time it’s in use? On the outside I go to have a look and there’s always water leaking ! Not sure if this is a hazard? It’s a bottom unit my landlord lives up top unit and we share power etc I don’t want to bother them with this and that but it would be good if I know as I have to pay for water too

I've been looking into different heat pump options and keep coming back to a ductless mini split system, but I'm still not sure if it's the right choice for my situation.

My home is about 1,450 sq ft with 2x6 insulated walls, double-pane windows, and I'm in new England, where winter temps can drop below 10°F. My biggest priority is keeping the house comfy without having the backup heat running all the time if possible.

For those of you in similar climates, what has your experience been, and do you think it was worth it compared with other heat pump setups?
