temporary fix. When the cold weather came we found we had emergency heat only, but we had a woodstove and oil filled radiators that sufficed. So far so good. We have managed for eight years this way. It's probably not been the most efficient method of heating and cooling our home but, it has worked. Our power bill runs anywhere from $180.00 to $350.00 (extremely hot or cold months) a month. We are almost afraid of what will need to be done to the heat pump after sitting this long. Any ideas what we will be dealing with, and what we need to save up to spend? The heat pump was new in 1987.

hardwood put directly on top. We have looked everywhere for water leaks. The closest sinks and bathroom (mbath) is in the room next door but there is no sign of water there on the floor. We have turned everythin off in that bathroom and not used it for a week but it does not appear to change the line on the floor. The water meter does not move at all so whatever it is is very slow. It has been like this getting steadily worse for the past 2 months.

Does anyone have any ideas. We are hoping not to have to pull up the hardwood floor.

speed fan would run in high speed most of the time. With the new thermostat, the air handler's variable speed fan does not run at the higher speed, at least not yet. I have only had the thermostat installed for a few hours. I have checked and double-checked the wiring from the air handler to/from the new thermostat and I have compared the wiring to the way the old thermostat was wired. Everything appears to be wired correctly. What ideas and suggestions do you have? Any and all ideas would be greatly appreciated.

for a while and then shuts off when the house reaches the set temperature. The system will sit in the off state for quite some time. After sitting like this, when the system first comes back on, I hear a rather loud grinding/jet like noise sound which appears to be coming from the area of the air handler. The sounds lasts for a few seconds and then stops. The system apears to cool normally after this noise occurs. The sound is a little hard to describe but it almost sounds like a jet plane flying over the house at a high altitude. The sound does not occur every time but when it does it happens after the system has been idle for an extended period of time.

A few days ago, I had my air conditioner repair company out to check the system. Of course we could not get the system to make the noise while the repair technician was present. He checked the system over, doing all of the normal things that are checked during a system tune-up. He could not find anything wrong. The sound still persists on an intermittent basis. What could this sound be and is it cause for concern? No parts have been replaced but the unit was checked out a few days ago.
