We have about 12 year old central ac unit in Texas. We have had off & on problems with the ac for the last 5 years we have been in our house. The most recent issues have been: 1. AC would not cool so we replaced the the capacitor & hard start relay two weeks ago. Well in my husbands attempt to do it himself, first he hooked the hard start relay on wrong & it sort of blew up in his face. Luckily everyone was ok. We were told (by a friend AC guy, the relay was ok for a bit) 2. One week ago, no power to unit upstairs or down. The breaker in the main power box was not working correctly so we replaced that breaker. 3. 4 days ago, outside unit kicks on & you could hear the compressor trying to kick on but it would not stay on. Left the unit off for 12 hours or so while we were at work. Fixed the hard start relay. Eveything has been great....sort of.... I mentioned that I thought the lights were flickering a few times the ac tried to come on. Everyone around here said I was crazy. Well tonight I"m up because I was hot & noticed that the thermostat said it was 79 in here but it is set to 72. So I go outside & notice the compressor was not running. I shut the unit down, waited 10 minutes & turned it back on. The unit comes on (fan is running) and the compressor tries to kick on but will not stay on. We do not have the money for a new unit even though we have been advised we need one. We are low on funds & are trying to do it ourselves. Any advice and knowledge is greatly appreciated! Thanks.Read More

Hi all, I am entering my fifth year living in a 808 square foot home built in the 1950s. It has hardwood floors original to the house with age showing, so bad I can see through some of the cracks! The crawl space and walls are not insulated and the attic was just insulated to around R-30 two weeks ago. Now, here is my problem. Last spring, my house started not cooling anymore - it was blowing just not cold. I have a 2003 Weather King 2.5 ton central unit with a horizontal air handler in the attic. Model #10JA2501 for the unit. The entire central unit (including all duct work) was installed in 2004 by a friend of my brothers (brother owned house then). Anyway, I called a service tech out last spring when it started acting funny - low on freon, recharged and went on his way. Cooled for a matter of hours and was hot again. When I say hot, in South Georgia today humidity at 100% feels like 110 outside! So, I called him back the next day, well convenient enough my compressor apparently went "bad" overnight and that was my problem. $900 later I have a new compressor, since five year Warranty with Weather King expired two months prior! Yeah, nice. Well, next day after new compressor installed - no difference. Hot. Called him back - an convenient enough he tells me unit is too small for house. Let's do those measurements again, 808 sq ft - 2.5 ton unit, too small? No, I didn't get a new unit, I called three more companies each with a different result. First, said copper line from unit up to handler was too small (it was 1/4 ") he replaced with 3/4" said that was problem. Cost me $100. Next day, hot. Called him back, he says unit hit by LIGHTENING (no weather overnight now) and that I need a new unit. Second company, said unit too small for house. Third company (came today) said coils dirty and needed freon. Its 7:45 my unit has been on 82.50 since before they arrived at 11 a.m. this morning and still is with target temp set at 75. Last night, it was 93 at 8 p.m. and did not drop below 85 until after midnight. All last summer light bills were around $400 for an 808 sq ft house, because this thing never shuts off! I told the guy today that before the compressor was replaced the unit outside would occasionally make a very loud hissing noise for around 30 seconds then resume at normal sound. Today the unit outside has a slight hissing to it. He said something may be wrong with valve, but was going to research it and follow up with me tomorrow. What do you think? I don't know what to do, I have done put more money than I had in it as it is. I could have bought two units with all the service calls I have paid for and work that didn't change anything. I have a one-year old daughter in here all day, and I am going to have to pay for childcare just so she is not in this steamy house - it's dangerous for her. Any suggestions would be helpful. Oh yea, we also replaced the old thermostat last month with a rite-temp #6620.Read More
