Urnace fan of some sort runs all the time - set on automatic
Our electric bills have been higher than if we actually heated with electric. 1900 square foot patio home (built 1997) electric bills running 250.00 gas bills 225. furnace fans (seems to be one on bottom of furnace and the other one seems to be blower fan--one or the other runs 98 percent of time. Have furnace serviced and checked twice a year Can't find manual. Please help.
Re: urnace fan of some sort runs all the time - set on...
If you have it cleaned twice a year they should be able to find this problem. It is one of two thinkgs. There is a limit switch on the fan at the top (inducer) this may be weak and causing the inducer run frequently. The other is there is another limit switch it is a main limit on the fire wall it is also weak and that is why the main blower is running it is trying to cool that limit.

If you have a dual fuel system - gas/heat pump the heat pump should lock out at around 41 degrees depending on what the outside lockout sensor is set at. It may be that both the heat pump and furnace could be running at the same time if the outside lockout isn't working or there could be a problem with the thermostat. Best bet would be to have a service tech check it out. However if you want to check it out here are the terminals Terminations: R,Y1,Y2,W2,E,G,O,B,L,C. W2, E and B are the heating terminals for 2nd stage heat and emergency heat. First stage heat, compressor Y1 with B (reversing valve on heat pump) energized together. 2nd stage W2 energized for gas or electric heat . No power to Y1 and B when W2 is energized if gas. E can be energized with Y1 and B if you have electric heat or if you switch over to emergency heat, E will be energized.
Yes, if you are talking about a heat pump. It you have an electric furnace inside, the electric elements are for emergency heat. Otherwise, unless you switch it manually at the thermostat, the heatpump (outdoor unit) will run all year around. If you want to use your inside heater (electric heater) just switch your thermostat to "emergency heat" and it will turn on the electrical elements instead of the outdoor unit. This way will make your elec. bill higher tho. The heat pump is much more efficient. Hope this helps you , have good day
Please understand first, air conditioning system not only cooling the area but also removing the heat. If heat in the room stays constantly, even 24 hrs running a/c couldn't cool the room. Now, why the a/c could not cool the room or remove the heat from the room. Check air filter, evaporator coil and blower wheel for clean. If not service the unit immediately. And also check indoor fan motor rpm. If rpm is low, replace fan capacitor. Check for gas pressure to confirm no leak or running with short of gas. It's advisable to service both indoor and out door once in 6 months at least. Otherwise, your electric bill will kill you lot. Thanks.
I have a related concern. I put the Mr. Slim unit in my garage/workshop and most of the time need it just to keep the pipes from freezing. I'd like to set it at 45 or 50 degrees, but the lowest it allows is 59. I bought this to save energy, but it's forcing me to keep the room warmer that I'd like.
Okay did you check your thermostat to see if you have the fan switch on auto? The switch must be on auto or the fan will continue to run. If the thermostat fan switch is on auto then there is a malfunction in the thermostat probably. You can go to your forced air unit and on unplug the unit. That way it will not turn on at all, because the forced air unit is controlled by the thermostat. Hope this helps.
Yes a higher SEER can help reduce electric costs. However. In most cases this will require changing both the indoor and outdoor units. In other words if you have a 10 SEER matched system and only upgrade the outdoor unit to a 14 SEER you will not get exactly 14 SEER efficiency. They must match.
Before excepting bids on new equipment I would first higher a licensed company to measure the Heat gain/loss from you house. This information will tell you if the current system was originally sized correctly. The improper sizing can lead to high electric bills as well. I hope this helps.
It sounds like the unit has lost its first stage of Heat (It uses the outside unit to bring heat in with freon) When the thermostat is put 3deg higher than room temp it uses Heat Pump and heat strips, this is probably the only time yours heats. Have it checked as you will pay a lot on next month's electric bill.
