have a question about my air conditioning unit. I have contacted the company that put it in, and have gotten a line of crap everytime. First off, My house was built in 2001, and I moved in that year. I have a heat pump. Part under the house, part out side. This is kinda long, but please bear with me. Thank you
In 2002 the air conditioner froze up on a hot day. It froze on the outside compressor I guess. (The large round tank looking piece with the fan next to it) And it froze the lines coming out of the out side. (the ones with the foam type insulation on it. I called for the repair man to come. He came and said that it was probably the circuit board on the unit not communication. He said they would put another one in. He said that my drain was also clogged, and he unclogged it. Well, the unit was fine for the remaining summer. I figured they put the board on (it was under warranty) and everything was fine.
Well, it happened again in 2003, same as above happened.
In 2004, It happened again same thing (if froze up). This time another tech came out. He said I had fungus type stuff growing in the unit pan. It had clogged the pipes, backing water into the unit about 6 inches shorting out the board. He said he cleaned it out, put some replace it the following week. He said it should be fine until then. He also said he wired the fan so it would run so the air conditioner. He expressed that we had to get the board on it case it would burn out the fan. So I thought that they replaced the board again, (still under warranty) Well the unit worked again for the remaining summer.
Well, it happened again this week. I don't know if it froze up this year because it flipped my breaker in the middle of the night. They were unable to come out that day, so we went under the house a pulled the plug to drain the water drain. The complete bottom of the unit was dripping water. The same guy that came out the first two years was back again. He said he had never seen so much fungus in a unit. The pipe wasn't clogged but, it was clogging in the unit itself, preventing the water to even make it to the pipe. He said that the complete unit was rusted out from all the water. He also stated that he had to wire the fan, and that the board was shorted out from all the water that had back up inside of it.
I called the owner of the company this morning about the problem. I told him that I wanted to see the records they had on the unit. I wanted to find out what exactly they had done with it over the years. I told him about the fungus problems, and made out like that was my problem, he couldn't do anything about it. When I told him I called them out originally for it freezing up, he changed his tone. He said that it freezing up had nothing to do with the fungus, that what I was saying did not make since. I told him that I didn't know anything about air conditioners, that I was just telling him what happened, and that his techs told me. He said he would have to talk with the technicians to see exactly what had been done.
My question to you I guess, Does this sound right? Do you know what could be causing either problem? Any help would be appreciated. Thank you very much for your time. It is a York Unit.
