Humidifier Maintenance

A condenser pump which had worked fine for years was suddenly no longer working when the technician completed his work and left the house. It was filled with gunk which he did not clean out, despite the high cost of the furnace humidifier maintenance annual contract. The result was a full pump reservoir, which causes automatic shutoff of the furnace, which happened to be on the 2nd coldest night of the winter (low 20s). I discussed my experience with Rodney so the company is aware that I was dissatisfied. Last year, the same tech handled the water feed tube in the humidifier device, and it was fragile and broke. Last year, he said I could just buy tubing at Home Depot to replace it. So I did that and his advice turned out to be completely false as what I really needed was a feed tube assembly kit and I learned how to replace it myself, with the aid of the manufacturer's parts supplier. This tech won't be coming here anymore, which was what I specified to Donna last year, but somehow that was overlooked and he showed up & I had another bad experience.

Poor supply chain management, arrived with wrong part, lack of communication on what was needed since different technicians were sent.

Very poor customer service. Make promises but we are disappointed each time. Expensive and the work still isn’t done.

Poor No longer wish to be a customer

I spoke to Shelton Cartwright from Water Furnace. My neighbor is getting a Water Furnace geothermal system in his new house from Bay Heating and Cooling in Annapolis. We will use them for our future service needs. Alex refused my phone calls about the problems we have been experiencing about not coming to our home for prescheduled appointments. Go to hell!!!

During the daylight it was easily recognizable that the leak was coming from the king valve that was not all the way backseated and the cap was loose on it. I backseated all king valves and put thread sealer on the threads and tightened the caps up as tight as they would go. I also tightened the bottom flare a little bit but it had not appeared to be leaking. I pressurized to 450psi with dry nitrogen and used soap bubbles and electronic leak detector to see if there were any remaining leaks and there were none. I then evacuated the system and pressurized again with dry nitrogen and let it hold pressure then used the nitrogen to flush the lineset. I then pulled system into a <500 micron vacuum. I called Mitsubishi to see if any additional charge was needed and was told that the data plate was the only charge amount required. I weighed in 4lb 3oz and cycled the unit to heating. I left the indoor unit set to heat to 70 so that by the time the customer gets home they will see that it is wo
