The furnace is hot and every once in a while the burner will come on for a short time and then go off again. But the blower that should be running to circulate the hot air from the furnace to the house is not working. How can you fix that? It really isn't very hard.It does not matter what the fuel of your hot air furnace is. If the blower is not circulating the air through the heater then you are not getting warm. The function of the blower is to move the heat from the heater to the space that need to be heated.A few simple tests can tell you what your problem is. Do you have power going to the motor that runs the blower? If you have power going to the motor and it is very hot than maybe the blower wheel has come lose and it is stuck on something that is keeping it from turning. Try to turn the wheel to see if it is stuck. If the wheel is not hitting anything and just turns hard then the bearings of the motor are bad and the motor needs to be replaced. In some rare cases the motor has little tubes to the bearings and some oil can be worked into the bearings to free them up. This is a long a tedious process, but I have done it successfully a few times. If the wheel is hitting something, then try to see if it can be fixed. Sometimes the set screw will just come lose from the shaft and repositioning the wheel and tightening the screw will fix the problem.Sometimes power will be going to the motor and nothing at all is happening. Replacing the motor is then the only option. The worst case that happens and is one of the most common problems is for the hub of the blower wheel to brake off. This lets the inside of the wheel fall down on the motor shaft. The metal from the wheel will saw off the shaft of the motor rather quickly as it is spinning trying to run the blower. The result of this is a ruined wheel and motor. This gives a brief overview of some of the many things that may happen to your blower in your hot air furnace. I have encountered many other things over the years, but these are the most common problems. It will give you a few things to look for if you are having problems. Be very careful because many times the edges of the metal pieces are very sharp. You can be cut very easily when checking or handling these parts. I know and have the scars to prove it! Do not be in a hurry and be safe.
Understanding the Essentials of Furnace, AC and HVAC Maintenance
This article will help to explain what the different parts of a home Heating, Ventilating and Air Conditioning (HVAC) system are and help you understand what work is being specified on an HVAC repair price list. For the purposes of this example, we will look at the components of an all-electric split heat pump system most typical in home HVAC installations.The heat pump itself is the outdoor portion of the system. It consists primarily of the compressor, condenser coil, and fan. It also houses the reversing valve and electrical contractors. This is where your service technician will hook up his pressure gauges to see if there is the correct amount of refrigerant in your system. If refrigerant is needed, it is installed here through a port. The bottle containing the freon will be weighed by a scale before and after filling your system to determine how much was used, and you would be charged by the pound. If there is a refrigerant leak in the coil it can usually be repaired, but all the refrigerant may have to be pumped out and reinstalled. Sometimes the fins on the condenser coil will be bent up due to hail damage or may be dirty. These can be combed out again or cleaned for little cost. If the fan or compressor do not run, or the reversing valve does not change the system from heating to cooling, it is possible that only a contactor may need to be replaced. These contactors, thankfully, are low cost components. But if a fan motor or compressor needs to be replaced, it can be more expensive. The compressor is the most expensive component and can be several hundred dollars to replace. If the condenser coil is badly damaged or the compressor needs to be replaced, it might be time to consider a new heat pump, particularly if much more energy efficient options are available.Indoors you have the air handler, which consists of the evaporator coils, indoor fan, air filtration system, humidifier, and a plenum for air vents. One of the most expensive repairs here can be for an under-slab plenum that has rusted out; this can sometimes require that part of the slab be demolished and reconstructed. It is unusual that anything goes wrong with the evaporator coils, but sometimes they need to be cleaned, which is an inexpensive operation. If the indoor fan motor needs to be replaced, it can be moderately costly. The air filtration system and humidifier usually only require simple repairs, replacement of filters, floats, small motors, etc. There are also some control electronics including the thermostat; these can range in price from inexpensive to moderately costly. If the heat pump outside needs to be replaced, it is possible that you may want to replace the indoor air handler also if it will help provide you with the energy efficiency of a new system. Hopefully this will help you to have a better idea of what you are looking at next time you get a repair bill for your HVAC system. Don't be afraid to ask questions of your service technician, and if you don't feel comfortable with any aspect of the repair or if it's very expensive, be sure to get a second opinion before going forward.
