Heaters in HVAC systems do not typically have problems as often as Air Conditioners, but that does not mean that they never do. Here is a rundown of the most common heater problems, what they typically mean, and what could have caused them.
Most of the time, when you have issues with your residential or commercial heating system, it is due to a lack of maintenance. For example, filters need to be changed, air ducts should be cleaned, and the system inspected at least once a year.
However, some problems are caused by faulty parts. Therefore, we recommend that you have your entire HVAC system checked up on and tuned up at least once a year. This type of maintenance is not expensive, but the lack of having it done can cause costly repairs or replacements over time.
Central heating system problems
One of the most common heater problems is when your central heating system does not turn on. Many things can cause this, but most commonly, it is either a problem with the thermostat or a problem with the furnace itself.
If it is a problem with the thermostat, you can usually fix it by replacing the batteries or by cleaning the contacts. However, if it is a problem with the furnace, you may need to have it serviced or replaced.
Problem: Heater smells like burning
You know the smell, the first time you turn your heater on in the house for the year, everyone thinks the house is on fire. This is caused by dust and soot building up in the system over time. It is recommended to have your heater inspected at least once a year, and a good time is right before starting to use your heater.
Problem: Mold in your furnace
Mold can be a severe problem, and it is not just limited to the exterior of your house. Mold can also grow in the interior of your heating and cooling system, and this can cause many health problems.
Problem: Blower motor fan is not working
If you turn on your heater and don’t feel blowing air from your vents, or minimal airflow, you might have an issue with a blower motor. Again, this is something that you should call us for and have us look and see what the problem is.
Problem: Controls are not working
If the controls on your heater are not working, it can be a problem with the wiring, or it could be a problem with the actual control unit. If it is a wiring problem, it can usually be fixed by a furnace repair technician. If it is a problem with the control unit, you may need to replace it.
Problem: Heater won’t shut off
If your heater is on and you can’t seem to get it to turn off, it could be that you have a stuck thermostat. If this is the case, you can usually fix it by turning off the power to the furnace at the breaker box. Then give us a call to come to diagnose the furnace problem.
Problem: Gas furnace will not light/stay lit
If your gas furnace does not light, it could be several things. It could be that you have a problem with the igniter, or it could be that there is not enough pressure in the system. If it is a problem with the igniter, it can usually be fixed by replacing it. If there is not enough pressure in the system, you may need to check the pressure. This is another reason you should call Crisp Climate Control to have a furnace repair professional diagnose your heater problem.
Problem: Heater blows cold air
If your heater is blowing cold air, it could be a problem with the furnace itself, or it could be a problem with the ductwork. If it is a problem with the furnace, you may need to have it serviced or replaced. If it is a problem with the ductwork, you may need to check the ducts.
Problem: Air Filter is dirty
A clogged filter can cause several heating and cooling problems. It will not only cause the heater to work harder, but it also causes your system to run less efficiently. This will cause you not to feel as much blowing hot air because of the lack of airflow. In addition, the lack of efficient use can cause more energy consumption and higher utility bills.
A dirty air filter can even be dangerous because the fan on your furnace circulates the air throughout your house. If you have dirty air filters, then it can cause the dust and dirt to be circulated through the home. This can cause several health problems, including asthma and allergies. Therefore, it is recommended that you change your air filter at least every three months.
Problem: Furnace is Short Cycling
If your furnace is short cycling, it turns on and off too frequently. This can be caused by several things, including a dirty air filter, low refrigerant levels, or a problem with the thermostat. If it is a problem with the air filter, you can usually fix it by replacing the air filter. If the problem is low refrigerant levels, you will have to have that checked. Finally, if the problem is a faulty thermostat, you may need to have that replaced.
Problem: Some parts of the house are not heating up
If you have a problem with the heating system in the house, it could be a number of things. It could be that there is not enough airflow throughout your ducts to those particular areas, or it could be an issue with the furnace itself. If there is not enough airflow to those areas, you may need to check your air ducts. If the problem is with the furnace itself, you may need to be serviced or replaced.
Electronic ignition fails to light
If you have an electronic ignition conventional gas furnace, there are many things that could cause the pilot light to fail to light up. For example, it could be that your gas valve isn’t sealing correctly or it could be that the wiring is faulty. If the heater repair professional determines that it’s not a problem with either of those items, they may recommend that you replace your electronic ignition furnace.
Furnace blower Is Noisy
If your furnace blower is making a lot of noise, it could be a sign that there are major furnace problems. It could be that the bearings are bad or a problem with the blower. If you think that your furnace might be making too much noise, you should call us right away to come out and check it out.
Can a furnace stop working?
A furnace can stop working for several reasons. It could be that the furnace is too old and needs to be replaced, or it could be that there is a problem with the furnace itself. If you are having issues with your furnace, it is crucial to call us right away to come out and take a look at it.
The pilot light is out
A broken or unlit pilot light is one of the most common reasons a furnace may stop working. If you have an electronic ignition furnace, it might be that your gas valve isn’t sealing correctly, which can cause low pressure and prevent the furnace from lighting up. It could also be that the wiring to the electronic ignition system has gone bad.
Furnace Frequently Cycles On and Off
If your furnace has been constantly turning on and off, it is a sign of something wrong with the furnace. It could be that your thermostat is set too low, or it could be that there is a problem with the furnace itself. If you are having this problem, it is crucial to call us right away to come out and take a look at it.
House is not getting warm enough
If the house does not seem like it is getting warm enough, it could be a sign of a problem with the furnace. It could be that something is blocking the airflow to certain parts of the house, or it could be that the furnace is not working correctly.
Causes of Heater Problems
Several different things can cause your furnace problems. It could be a problem with the furnace itself, an issue with the gas line, or a problem with the thermostat. If you have noticed any problems with your heating system, it is essential to call us right away so that we can come out and take a look.
