Heating and Air Hvac

Question by Donq: Central air conditioner does not work.?

My central air condioner does not work. I have a heat pump style air conditioner/heater. The heater does not work either. The pump is about 10 years old. I’ve reset the circuit breakers and reset the fuse but still having problems. Any recommendations before I call an expert and when I do call an expert how much am I talking about for repair costs? I live in Virginia. Thanks!

Question by HeatherK_24: Where are the filters located in my furnace – Heil 7000 heating/cooling unit?

I bought a house a few weeks ago and I want to be a responsible homeowner and replace the filters monthly. I took the cover off and cannot find where the filters are located. Any guidance would be greatly appreciated!

Answer by Jrbott
They are normally located where the cold air return duct attaches to the furnace. Hot air duct goes out the top of the furnace. This can be at the bottom on the side of the furnce or the furnace can actually be sitting on top of the cold return. Some have a small door that opens up, others you have to take the front off to get at the filter. If it’s on the inside make sure you get the filter into the channels correctly or it could get sucked into the fan.

I would be inclined to stay away from Ideal.What about the new Baxi range, the duotec is available up to 40kW.

Question by rcorey123: can anybody tell me about service valves on an airconditioning unit and the positions of the king valve when i

what is open when the valve is either all the way in or all the way out or in any position

Best answer:

Answer by arnon74
the valve has three positions. Turn the stem clockwise until it seats and the flow from or to the compressor is shut off. Turn the stem counterclockwise to seat and the vale is open for normal operation. Anywhere in between is the position used for charging vacuuming or checking pressure.
