My Comfort Maker system is less than a year old but has an issue I need help diagnosing. When it was first installed, in the summer, it ran fine but within a month stopped cooling. I assumed there was a leak and was able to get the original installer (o.i.) to come back and check it. The o.i. said "There is no leak. The refrigerant lines are getting blocked and need to be vacuumed out and re-filled." Which he did on three occasions because every time within a few days it would stop transferring heat. Soon the o.i. was MIA. My home warranty sent me service company "A" who basically said, "I don't know what the problem is but it might be a leak in your traveling lines, which are not covered by the warranty. Goodbye." I brought in a highly recommended (and expensive) service company "B" who said, "The TXV needs to be replaced. It's failure is causing the refrigerant lines to get blocked. Also, the compressor is making a lot more noise than is normal and may need to be replaced. Also having an acid test done might be a good idea to see if there are further compressor related problems." Since the TXV and compressor was covered by my warranty, I asked my home warranty for a second opinion and they sent service company "C" who recognised the need for a new compressor and I suggested he replace the TXV. He made the repairs and it worked. It worked wonderfully for about 5 days until I switched the thermostat to "OFF" because I was going away for a day and didn't want to waste money on cooling an empty house. When I returned and switched it back to "COOL" the unit ran but after two hours without dropping the house a degree I checked the condensing unit and the pipe supplying the cold refrigerant was cool but not even cold enough produce condensate on a 90 degree humid day. I gave it 4 more hours without a difference before I turned it off to not ruin the compressor. I think that switching the T-stat "OFF" is a key part. After the original install I did turn the T-stat off at some point, and there after I noticed it was no longer cooling. Any suggestions on what the problems could be, and how I can best get it resolved? I've been dealing with this for a year, my warranty is up at the end of August.

My concern is that there is no space on the two sides of my house, so the only place to put it is in the back behind the house. However, the place they suggested has a stairway leading up to my second level deck. The condenser would sit underneath the stairway. While it doesn't completely cover the top of the condenser, it covers about half of it with a clearance of about 3 ft to the bottom of the stairs. I'm concerned about the unit not having enough open air to shoot upwards and I'm concerned about the bottom of my stairs being constantly hit by air and steam discharge from the heat pump. Should I not be worried?

For the electricity it seems you are buying the electricity from another provider. There is delivery charge from National grid for $61.49, and a service charge of $75.71 from another supplier. The average cost for 701 kWh is $0.196 per kWh. That is is expensive. You probably would get a better rate if you bought your electricity from National Grid. National grid also offers other types of billing. You should call them and ask about all the available options. The gas chart is showing a price of $0.22 per therm. That is very low so I suspect that is only the delivery charge. Are there more details on your bill showing the service charge?

Hi Adam, Thanks for posting. After much online searching (including communicating directly with Miele, whose "Help" line was actually no help whatsoever), I was going to replace the solenoid when the dishwasher "magically" started working again (and has remained working). Try a different cycle choice, and give it a couple of minutes to try to kick in. Good luck. -Alex
