If furnace is electric why is the gas bill high? I have a vacant home in Utah, built in yr 2001, and the only thing running is the furnace which is electric. The house is 3,800 sq ft and the only thing on is the furnace set at 55 degrees. There are no appliances in the home with the exception of a refrigerator and a gas stove. Why would the gas bill for an empty home be $160 when the only thing that is running is the furnace but it's electric? Thanks in advance. I'm not sure if the water heater is on and if it's gas or electric. However I shut off my water service so I don't have water. My electric bill is $95 for 1,109 kwh for this month and gas $160. If my electric furnace is forced air why would it use so much in gas though? Thanks all for your replies and helpful suggestions.
Why does my furnace create an odor when running? This is my 1st winter in a cottage that I am renting. Every time that my furnace is running, there is a bad odor throughout the basement where the furnace is located. It smells pretty bad. My neighbors have the same problem. My neighbors house is the same as mine and has the same owners. The furnace is really old also. What is causing this odor? It's a gas furnace.
Does an electric furnace cost the same amount to buy and install as a gas furnace? What are typical prices for a furnace for a 3 bedroom house, for gas or electric? Do they come with the A/C evaporator coil in them, so we can hook up our central A/C system to the furnace unit? Or would we have to install the A/C coil separately?
Why is my natural gas furnace making buzzing sounds? I have a natural gas furnace and noticed that on an intermittent basis it makes a buzzing sound. At first the buzzing sound didn't happen that often, but now it is happening more frequently. The furnace will buzz for several seconds and then stop. Then at some random point it will buzz again for another few seconds. This only happens with the furnace is actually running. The furnace is still producing heat. In fact, apart from the buzzing sound, it is working normally.
Whats the difference between an electric and gas furnace? as far as cost and upkeep go? I'm looking at Condos right now one has a gas furnace and water tank, while the other 2 have an electric(forced air) furnace and an electric water heater. Which is more expensive to run in terms of energy bills? Do Electric Furnaces last longer then gas? Are they cheaper to replace? Does an electric furnace use a heating element or what?(vs a gas using a flame) The one I'm looking at still has an electric furnace from the mid 70's. Should i be worried?
Is shutting off the furnace a few hours a day a good way to save heat? I'm really trying to conserve on oil consumption in my house. I turn down the thermostat, my tenant does so as well. But the furnace still kicks in when the temp drops to what we've set them to. What I've tried doing is just to shut off the furnace on weekdays. I'm alone, so it's no big deal for me. I turn it back on as soon as the tenant gets back from work. I'm wondering, does this really help or am I actually using more heat when the furnace restarts after being shut off for 6 hours? It also has to heat the hot water tank (30 gallons). Thanks for your input!
What is involved in getting your furnace serviced? I know I need to get my furnace service and my ducts cleaned -- this will be our 3rd winter in our house and it's never been done. What does duct cleaning and furnace servicing involve? Can you give be price ranges? Do they use a big vacuum type thing? Is there any drawbacks to having a furnace serviced? For example I know if you flush the transmission of an older car that hasn't regularly been serviced the cart usually ends up with transmission problems -- has anyone had similar problems with their furnace? Thanks in advance! I'm definitely having a professional come in and do it. I wouldn't even know where to start myself -- I was just wondering what the process is like.
What could cause my gas furnace to stop a few minutes after it stops? This furnace is less than ten years old and it's been serviced every year. It's been the fourth night we needed heat and more than half the time the furnace stops before heating to the thermostat setting. This has been happening at the beginning of the season every winter. Various technicians have looked at it, cleaning and replacing parts like the "heat sensor" or "flame sensor." Should I just give up and get a new furnace?
Installed a new furnace fan and now my smoke detectors chirp when it starts up. What gives? Over the past year, as my old furnace fan began to wear out, one of the smoke detectors upstairs would chirp whenever the a/c started. Yesterday I replaced the furnace fan and this morning when it the a/c started, all of the smoke detectors throughout the house chirped, some of them several times. Strangely, it did not happen every time the a/c started.

How do I get my furnace to blow hot air again? My furnace kicked on today for the first time this season. It worked at the end of last season, but now it is blowing only cold air. I replaced the thermostat (meant to do this anyway) and still no heat. I pulled the service panel off and the LED is blinking 3 times.

What is the voltage and amperage of the electrical connection at my furnace? I have a Coleman 7600 propane furnace heating a 1000 square foot house. The furnace has an electrical wire going into it to power the blower. At some point in the future I might get a woodburning stove and get rid of the furnace. So I'm thinking I also will be able to put an electrical outlet where the furnace is now. What kind of electrical connection (voltage and amperage) would have been installed for this furnace?
Does an old furnace use more oil? I am renting a 2 bedroom apartment, most of which is in a basement. I received my fuel oil bill today, and in the past 30 days, it says my furnace has used 228 gallons of oil. We've had some issues with the furnace not working earlier this year, could there be something wrong with the furnace that is causing it to use so much oil? It's more than my parents consume with a whole house!
My furnace kicks on and off and it is turned off on the thermostat. Any ideas please.? Hi, my furnace is only a few years old and it has been kicking on and off....when the furnace is shut off. It is a standard blend air, model # 7681-819 1/a . When I took the cover off the furnace it has a switch that says... off-fresh air-auto. It is set at off. The furnace people said there is nothing wrong with it but there is...because it is turned off and keeps turning on. The thermostat on the wall says it is off. The options are...cool-off-heat. It is off. Any answers would be great to help solve this. Like I said 3 different furnace people have been out and nothing is resolved. Thank you! All the answers sound wonderful except this is a GAS furnace, not a hot water furnace. I forgot to point that out. It has been off now for 2 days and it still kicks on and off, within minutes of it turning off, it turns on again. It happens every few mins. Thank you.
Is it safe to store stuff in a furnace room? My house has a new natural gas furnace in a room tht is about 6ft wide, 14 long and 3-5 feet high. The room has an entry door, and a large 2x2ft vent going to the furnace and and exhaust pipe out the roof. There is plenty of extra space around the furnace and I am wondering if it would be safe to store stuff up there, like boxes and a table. Any special packing materials? Anything I should not store up there besides the obvious like combustible liquids?
How do I know what thermostat would be compatible with my furnace and air conditioner? I bought a new thermostat recently and hooked it up. I know the wiring is correct because I checked the wires all the way back to the furnace. The furnace is working, but the air conditioner will not turn on even though the wiring should be correct. I checked the filter, and that is clean. The only other option suggested to me was that maybe the thermostat wasn't compatible with my furnace/air conditioner. How do I know I'm getting the correct thermostat? I checked the manuals, and they don't say anything about a specific thermostat needed. The new thermostat I have didn't have any specifications that I noticed (as in: Only use with certain voltage of furnace/certain brand, ect.) How can I tell? So if I 'jump' those two wires and the air conditioner doesn't come on with in 10mins, does that mean that something is wrong with my air conditioner? Besides the wiring being mixed up, can anyone think of anything else that might be the case for the furnace working but the air conditioner not? (PS. Thanks for all the help! I really appreciate it since I can't afford to hire someone right now, and my hubby ISN'T a handyman sort!.)
How much should a natural gas furnace be turned down during the day? In the morning before leaving for work, we turn down our gas furnace from 70 to 60 degrees.

Would the fan on the furnace work even if the condenser outside does not? Have interruptible a/c service - put fuse in outside, turned a/c on - temp does not seem cold enough. Now I think all that is running is the fan on the furnace - blowing cool air - I have not seen or heard the condensor or fan kick on. So I just turned the system off as well as the fan on the furnace so I don't blow that out while I try and figure out what is wrong.

Gas furnace draining lots of water while the heat is on.? My gas furnace has been draining a lot of water from the condensation tube for several weeks of heating now. This wasn't a problem the past two winters. I do have a built in humidifier, but I've turned it off for several days and it didn't change the amount of water that is draining. Normally I wouldn't get any drainage during the winter, only during the summer when running the A/C (which I know is normal for A/C). Any ideas what could be causing the sudden excess water creation and is it a problem that needs to be fixed?
How can I get my downstairs gas furnace to kick in quicker when I increase degrees on the thermostat? When I wake up in the morning the temperature in the house may show 69 degrees on the thermostat.

Anything else? Also if all else fails what is a safe cost efficient and energy efficient space heater?
What is the source of high pitched noise coming from water heater or furnace? I just noticed a high pitched noise, very similar to some of the newer alarm systems, coming from the garage. The two things there are the water heater and the gas furnace. The gas had been switched off about a week ago so we could reinstall a gas insert into the fireplace and, initially, the furnace gas stayed off (which we discovered because of no heat!). I don't know if this started right after - which is why I'm not assuming it's the furnace. Thanks!

I started smelling something when our furnace came on tonight and need to know if it could be anything harmful. This isn't the first time we've used the furnace this year. It doesn't smell like a first time of the year smell, it smells more like a "fumes" smell.
Why does my furnace come on so often? My furnace is set at 68 degrees and it comes on for about 3-5 minutes, turns off and then comes on again in 3 to 4 minutes? Is that normal? What is normal? Why is it doing that? It is a brand new home with a Trane Gas Furnace (XL or XR 90). The thermostat is Honeywell.
What to look for when buying a new furnace/air conditioning unit? Our furnace is quite old, and i have been looking into buying a new one, except i have no idea what to look for, or how much we may have to spend? We own a condo that is about 920 square feet, so i would think that we would not need a big one? Also our air conditioner is ready to take a poop on us, so i was also looking into the all in one units. Any help is greatly appreciated. Thanks i live in Ohio, and mid to high range efficency would be preffered.
