  • Wall furnace won't come on by itself

    Feb.6.2012

    I have a wall furnace heater (heat only). I set my furnace to 70 degrees and it will not come on by itself. I have to turn it on manually. Do I need a need wall heater system?

  • Heat for a few minutes, then cool air comes on

    Feb.5.2012

    When I turn my roof unit on, everything is set on heat. The unit will heat for about 10 minutes, then cool air starts to come out. I also have a small amount of air coming out of some vents in the three bedrooms and the kitchen. I turn the thermostat to 90 degrees and it heats for about two minutes. Then cool air comes out again. I had a tech come see if the unit was working before all of this. He said the unit was in working condition. Can you help me please? I'm a poor man with a problem.

  • Limit switch replaced

    Dec.21.2011

    We just had our limit switch replaced two days ago, and we have the heat set on 70 but there is cold air coming from the vents. Plus the fan run constantly until i have to reset it. Our maintainence guy said everything should be fine and that he will be out again in the spring for our annual checkup.

    The limit switch on your heating unit goes off if something gets too hot. Usually that means that there isn’t enough airflow through the system to push out the heat. First, I would suggest checking your…

  • Furnace will not turn off

    Dec.13.2011

    We have a new furnace that we bought from a wholesaler and had our contractor put in when we remodeled our house. It is an electric furnace and it will not shut off.

  • Fan never shuts off

    Dec.8.2011

    We have a window heat pump that has been installed for a couple of years and it seems to heat just fine except for one problem. The fan never shuts off. I have read the manual and messed with the controls and, unless you shut the whole unit off, you cannot shut the fan off. Is this normal behavior for a window unit?

  • Furnace and heat pump both ran all evening

    Nov.10.2011

    We have an electric furnace and heat pump. The whole system was shut off at the breaker for the summer. We just turned it on this week. Temperature was set for 70.

  • Cold spots with new heat pump

    Feb.10.2011

    We purchased a new heat pump to replace our old contractor model that is 12 years old. The technician suggested an additional air return be installed, which we did. We had a new installation service check performed and this winter we called to have the heating side of the system checked because we were experiencing cold spots or rooms in the house. This recent cold spell has hit the country and the house is cold. As the service technician suggested, we partially closed the registers in the smaller rooms to force more tempted air in the larger rooms and to turn our ceiling fans on low, which we did. Now the back of the house is cold and the larger room actually feels colder. We have to set the thermostat on 75 degrees F just in an attempt to warm the house. Just today, I fully opened all the registers to see if we can maintain a comfortable temperature in the house. This is a 2 year old system which has been serviced and maintained; there are no drafts or cold air coming in the doors or windows, and the house was constructed in 1995 so the insulation factor should be normal for this area. Our 12 year old contractors' model worked better than the new one. What else can be done? Something is not right with the system; the old system was not efficient but it kept the house warm; cooling was another situation. We need options.....

  • Furnace configured for natural gas

    Jan.6.2011

    I have a heating and cooling system that was installed 9/27/10. About 2 weeks ago the heating system failed (thermostat lost power) after multiple attempts to repair it. It was determined that the furnace was configured for natural gas whereas I have LP (liquid propane). I was informed that a conversion to a LP kit would fix my problems. I am concerned on multiple levels at this point. Does this sound like a reasonable scenario? Will it work?

    Frank, North Myrtle Be, SC

  • Unit does not produce heat; fan blows cold air

    Dec.31.2010

    When the outside temperature drops below 30 degrees, the unit stops producing heat and the fan continues to work blowing cold air. The inside thermostat would be set to 72 degrees and it does shows the heat is on and it reads the inside temperature correctly at 61 degrees or however cold it is after cold air has been blowing. I called the manufacturer and they do not have a manual. The installing company went out of business. Why is my unit not producing heat and the fan blows cold air? The fuse box doesn't show anything tripped. In fact, if I trip it, the heat will work but only for less than a minute and then it blows cold air again. Are my coils frozen? Should my unit go to an emergency heat backup system? This is an electric heat pump. I had the unit inspected this past February and they said it is fine and that they aren't meant to withstand such cold temperatures.

  • Humidifier not working

    Dec.19.2010

    I have a five-year-old furnace and the humidifier is not working. I checked the water supply line to the unit and it is okay, but water does get directed down through the pad (a new pad that I just installed). All electrical connections seem okay, and the control panel clicks once when I turn the dial to "test.” Oddly enough, the water pump activates periodically to pump water to the laundry tub drain, so moisture must be coming from somewhere. Like I said, the humidifier pad never gets wet.

  • System runs continuously all night

    My HVAC system sometimes runs continuously all night (6 or 7 hours straight) because of the windy wintery weather and the fact that my doors and windows are old and not air-tight.

  • Replacing thermostats and transformers

    Dec.10.2010

    I have a heat pump which is currently set to operate as a conventional heat system and is heating with the aux/em heat only. When I put the programmable thermostat in "Heat Pump" mode, the condenser compressor comes on as it should along with the aux heat but after a few minutes of running the aux heat contactors begin to chatter. This has caused the control transformer to burn out on two occasions. I want the system to operate as efficently as possible, but can't afford to keep replacing transformers and thermostats. I am using a Hunter model 44905 programable thermostat going to a Gibson 3TB split unit and by all appearances, it is wired correctly. I recently replaced both aux heat contactors and the transformer and thermostat. Could this be an issue with the outdoor thermostat (if one exists) or has my expert service company mis-wired the unit in some way. If the OD thermostat could be the culprit, how do I determine this?

  • Loud thumping sound from unit

    Mar.4.2010

    My Carrier heating unit is making a loud thumping sound about 45 seconds before it starts to blow air. I have had two techs out to try to figure it out and they have not found anything wrong. The thumping drives us nuts! It is definitely NOT normal. Both techs heard the noise, but neither of them could find the problem. The second tech took the time to go through the heating system, step by step, with me. We could not recreate the issue, but once out of the attic, he heard the noise for himself. This is a different sound than one hears when the ceiling filter is being sucked up to the top of its housing or being dropped back down when the system turns off. It's a dull, muffled "THUMP," wait 45 seconds or so, then the blower can be heard coming on. Any help would be greatly appreciated. Thanks.

  • Ice & snow buildup

    Mar.4.2010

    We have Carrier High Performance heat pump, installed in the past 8 months. This past week, we have had heavy snow (30") and ice (outdoor temperature 20F-25F) in our DC/MD area, but the heat pump heating function has been fine. Each day when I have been sweeping the snow away from the outdoor unit, the fan blades have been turning normally. This morning, however, I noticed the fan blades were not turning and that a large amount of snow and some ice had built up on the blades. (But the heater function had still been working OK during the night.) As soon as I removed the snow, the fan started up, but it was then badly out of balance, causing the whole unit to shake. I turned off the heat pump, removed the grill with the fan-motor unit, and scraped off ice that had built up mostly on two of the blades. After replacing the fan and grill, the fan now turned smoothly, without shaking. We have a wood stove that also provides heat to the main part of the house, and the heat pump unit shuts off when the wood stove is fired up. Maybe the snow is building up especially during these times. Now I am turning on the heat pump for a minute or two, every hour or two, when the wood stove is operating, to prevent snow build up again. What I would like to know, in case this happens again: Is it important to have the fan turning for the heating function of the heat pump to operate efficiently during winter weather like this? If so, is there anything I could spray on the blades to prevent ice and snow build up? Other suggestions?

    Jan.29.2010

    The pilot light [on my furnace] goes out as soon as I release the knob. When relighting the pilot, it comes on but immediately goes out before I can turn the main burner to ON. When turning the furnace on, the burner does not ignite as the pilot has already been extinguished. What is causing this problem?

    Edward, Danville, VA

    Expert Answer

    If the pilot light will not stay lit, please be aware that there is a safety issue. First, the gas valve needs to be checked for proper operation. The flame on the pilot light tells the gas valve everything is…

    ARS installed and brand new Carrier System in my house in Sep 2009. The new system does not require filters in the ceiling like the legacy system needed.

  • Clicking noise won't stop

    Jan.25.2010

    We had a new Carrier furnace installed on 2/4/08 and it was checked on 11/12/09. It has been working, but in the last couple of weeks, it makes a clicking noise when it comes on which doesn't stop until it goes back off. I seem to remember the technician telling us that the clicking noise should just be at first when the pilot light ignites, and then should stop. Why does the noise not stop now? We still have heat, but the noise is irritating and I'm not sure if it is dangerous

    Sue, Bethel Park, PA

    The clicking noise might be the electronic ignition activating continuously, in which case the part could fail. When a furnace has a spark ignition, the…

  • Have to keep relighting pilot

    Jan.13.2010

    My furnace shut off last night. The pilot went out, and I thought it was maybe because it was so windy. When relighting the pilot, it stays lit. When turning the furnace on, the burner ignites and the flames are coming out of the vents in the burner cover and upward. The furnace shuts down and extinguishes the pilot. What could be the problem? We tried relighting it three different times with the same results each time.

    The wind would have been my first guess as well. It sounds like there could be two things going on. Perhaps the thermocouple is weak. This electronic device is designed to sense when it’s safe to keep open…

    Jan.13.2010

    I thought I had an Appollo heating system but was told recently when the water heater broke that we were no longer using that. So I think I have a heat pump. The main unit is under the house and the only filter needed is under there...if that helps. The thermostat is set to 73 degrees. I checked it and it was only 66 degrees in here. Heard it kick off so I looked again. The thermostat had gone blank and would not come back on. I checked the circuit breaker and all is fine.

  • Heating two floors properly

    Jan.8.2010

    My home has a gas furnace that heats the basement and main floor, and an electric heat pump for the upstairs (both installed by ARS when the home was built in 2005). I have two questions regarding heating during the winter: Is it normal for the upstairs heat pump to blow cool air sometimes? Is it better to leave the furnace thermostat on the main floor at room temperature, even if everyone is upstairs? I have been turning down the gas furnace on the main floor during the nights when everyone is upstairs. However, the heat pump upstairs does not seem to be able to keep the second floor warm enough by itself.

    Jan.6.2010

    I have an ARUF024 Air Handler with a Simple Comfort 2200 thermostat. Recently the display on the thermostat started disappearing when the heat kicks on. Sometimes the heat turns off by itself, the display reads - - for a few seconds -- then the temperature registers again. Other times the heat will run forever if you don’t shut it off and hit the reset button. Do I just need a new thermostat, or is there a bigger issue? It doesn't happen every day either.

  • Heating with a wood stove

    Mar.2.2009

    I heat the lower level of my house with a wood stove. The lower level is approximately 3000 sq.'. This naturally removes most of the humidity from the air. I have a series of 3 low voltage, high volume fans, 2 up high that circulate the hot air from one end of the house, where the wood stove is, to the other while the third, down at the floor level, moves the cool air back to the end with the wood stove. This arrangement works very well at the distribution of the heat and almost completely eliminates the need to use the oil furnace all year. Is there a humidifier that I can temperately hook up to a water supply that will continually release steam or water vapor into the air without having to hook it up to my central furnace? I have tried the self contained, 2 blower units you can get at Sears. The problem is that even though they hold 13 gal. of water, I have to fill them every day which takes too much time. I was hoping there was something similar but with misting nozzles or steam that I could tap into a water line like I do with the refrigerator ice maker. This way I could place a unit near the cool air return fan, tap into the water line for the winter and forget about it till spring when I would just put the unit away till next winter. Even something like the units from Sears, the ones with the "wicking" devise would be acceptable if I could hook a water supply to them. I thought with the "wicking" type that you have to be concerned with potential bacteria and stuff. Thanks for your time and consideration of my problem!

    I just had a new electric furnace installed in November 2007 and from the time the furnace was installed to March 2008 I paid close to $4000.00 in electric bills. Now this winter from November 2008 to January 2009 I have paid a total of $2300. What could be the problem? My electric bill this time read $1300.00 with me using almost 18,000 kilowatts. I do not understand.

    I would start by making sure that the filter is clean, and continue to do so on a monthly basis. One of the most common problems we see is a clogged filter. I would also recommend that you ask the company who… Read more

  • Why doesn't my downstairs get warm when the heat is on?

    Jan.14.2009

    I have two separate cooling/heating systems in my home. Both systems are on and turning but the downstairs area is cold while the upstairs area is warm.  Why doesn't the downstairs system get warm if the system is on and operating? Is there something I can check for myself before spending a lot of money calling the professionals out to fix the problem?

    First I would ask when did you last check the air filter and when did you have the unit serviced last? The unit could be cycling on a limit and restricting airflow if the air filter is dirty or if there has been a… Read more

  • My 2 zone base board heat will not go down.

    Jan.12.2009

    I have 2 zone base board heat. My second floor is set at 50deg and the temp is 72 degrees. I have changed out the thermostat, cheked the wire for power, but the temp will not go down. I shut off the boiler at midnight and at 5am it was still 70 degrees. the 1st floor was set at 62 and the temp was at 62. my boiler has two circ pumps, both get hot when you turn up the thermostat. ANY advice at all would be a great help. I have been to 3 home centers and spoke to a dozen people most think it's the thermostat. Plumbers are a week to two weeks out.

    With this being a 2 zone system I am sure you probably have zone solenoids in the system. If the zone solenoid (insulated copper coils) for the upstairs loop is not shutting down, stuck or bleeding through you could… Read more

  • My gas boiler will not shut off.

    Jan.12.2009

    My heat will NOT shut off! I have a gas boiler, and also a hot water heater. The hot water heater is new, only 3 years old. We have a HoneyWell thermostat that is only 2 years old. I don't put our heat on much, only once in the morning to get the chill out. Our home stays pretty warm so we don't need it. Anyway, the other morning I woke up and it was hot as anything in here. It's been two days now and the heat won't shut off even though I put the thermostat switch on the "off" position. I generally keep my themostat at 68 degrees. The vents are constantly hot and we can't figure out what is going on here. Why would the heat keep coming on and the vents stay out even though the thermostat is OFF?? Please help! Thank you.

    If the burner is cycling but continues to heat over and above the thermostat setting there is a major concern and it is most likely cycling on a limit switch. If this is the case then if the limit was to fail and… Read more

  • My gas heater works fine but it is making noise. Is that a problem?

    Jan.7.2009

    When my 1st floor gas heater turns on in the attic it is quiet as a mouse. The upstairs unit, by contrast, ignites and heats as well as the other, but there is a sound like the whir of a playing card in the spokes of a bicycle. Is that a loose fan or something? It works fine, but the noise is a bit concerning. Thanks!

    Greg, Cumming, GA

    Expert Answer

    Depending on the age of the furnace, the main blower assembly or draft inducer motor can cause the type of noise you described. The noise could indicate a simple problem but at the same time it can lead to or be the… Read more

  • My outside heat pump will come on, but the indoor blower will not.

    Jan.4.2009

    My outside heat pump comes on but the indoor blower fan does not come on unless I raise the temperature on the thermostat, then the inside fan motor comes on. When I lower the thermostat below room temperature, then both the inside and outside units go off. If I don’t touch the thermostat at all, the heat pump will run forever and the inside blower motor will not come on. Do you know why this is happening?

    Dec.18.2008

    What would cause my furnace to shut off? My heat is not blowing out and when I turn the furnace off/on again, it sounds as though it is trying to ignite but then it will shut off again. No heat is being forced through the vents. I have Gas system.

  • Code five, what does that mean?

    Oct.30.2008

    I have a 2 ton Carrier package unit, model 48SS-024060301 and the LED code is flashing 5. I've just had the blower motor and Hall effect sensor replaced and it was working fine for about 2 weeks — then it got colder. The blower motor runs and the gas cycles on, but no sparking to light the gas. Any Ideas, is the control board bad?

  • A/C is working, but heat is not

    Oct.29.2008

    My programmable thermostat doesn't seem to have power and so the heating is not kicking in. The thermostat itself is fine as I can see it work on the other unit. I checked all the breakers on the panel and they are ok. Would there be any other breakers in the system that would cut off power to the thermostat and/or furnace? The switch in the attic is also ON. It was all working before (AC worked throughout the summer) and the house is only 4 years old. Thanks.

    nasser, bellaire, TX

    From you statement that "the other unit works," my guess is that you're speaking of the A/C unit and the indoor blower. If the blower is working with the call for A/C, then the problem would be associated with the… Read more
