Insufficient heat is a common problem for heating systems of any type. If your heater pushes out cold air or if your home just can’t seem to get warm enough, you should likely call for heating repair. There are a number of possible causes for this and we wanted to put together a quick list of the most common ones. Call your local heating contractor to perform any work on your heater. Trying to fix the problem yourself could lead to further damage to your system, or even cause personal injury.
If you aren’t getting enough heat from your furnace it could be caused by one of several different things.
- Clogged air filter. Probably the most common cause of all furnace problems is a clogged air filter. Your furnace uses a filter to keep out particles like dust and insect parts. If the filter gets clogged, it will restrict the flow of air through your furnace which could create a lack of hot air.
- Thermocouple. If your furnace is blowing out plenty of air but it isn’t warm, then you likely have a problem with the burner, and the thermocouple is a possible culprit. A thermocouple is a safety feature that shuts the flow of gas off to the system if it detects that the flames on the burner have gone out. This prevents the area around your furnace from filling with gas. But if the thermocouple malfunctions, then you won’t get any flames and your home won’t get heated even though the furnace’s fan might still run.
- Dirty burner. Speaking of the burner, over time it can get clogged and may not light: keeping you from getting any heat.
Another common type of heater is the heat pump. These types of systems don’t burn any fuel to heat your home. Instead, they absorb heat from the outside air and move it into your home.
- Air filter. Remember how we said that a clogged air filter is a common cause of furnace problems? The same is true for the heat pump. Make sure that you always regularly change your air filter.
- Compressor. In order to move heat into your home, your heat pump uses a compressed refrigerant. In order to compress that refrigerant, the system needs an operational compressor. If the compressor breaks, the system won’t be able to properly heat your home.
- Low refrigerant. If refrigerant levels in your heat pump run low, it won’t be able to absorb enough heat from the outdoor air to heat your home. This results in plenty of air from your system but not enough hot air.
If you’re having any issues with your heating system, make sure that you call your local contractor for professional repair. Ignoring issues like inadequate heat won’t make them go away.
Your heating and air conditioning systems are both vital to your home’s comfort throughout the year. Whether you’re looking to stay cool in the summer or if it’s time to heat your home in the winter, you need your AC and heater to work well. One of the most common (and easily avoidable) problems that we see is a clogged air filter. In order to protect the inside parts from large particles like dust and dirt, your HVAC system has an air filter in it, usually located near the return air duct. It needs to be changed regularly or it will clog and restrict the flow of air through the system. This can cause several serious problems for your home and we wanted to let our customers know about them.
Air Conditioning Problems from Clogged Air Filters
Your air conditioning system’s main job is to remove heat from your home and exhaust it outside. In order to do that, it uses a fan to pull in warm air from your home, then passes it over a series of very cold evaporator coils. The fan then pushes the newly–cooled air into your home through the ductwork. If the air filter gets clogged it will restrict the flow of air into the system and cause the following issues:
- Insufficient cooling
- Extra wear and tear
- Inefficient operation
- Reduced comfort
- Ice on the coils
- Strange noises
If you notice any of these issues with your system, the first thing you should do is check your air conditioning system’s air filter. Depending on the type of filter that you have, you may be able to wash it off and put it right back in. But most likely you will have to buy another filter.
Heating Problems from Clogged Air Filters
For heating systems, a clogged air filter can cause big problems—especially for furnaces. A burner in the furnace heats up the heat exchanger and a fan pulls in cool air from your home and passes it over the exchanger. If the filter is clogged it won’t allow enough cool air over the exchanger and it will heat up which could cause it to crack. A cracked heat exchanger can allow carbon monoxide to leak into your home which could be very dangerous.
Make sure that you get your heating and air conditioning systems regularly inspected and maintained by a professional. During regular maintenance visits, they will likely check the filter to make sure that it isn’t clogged or alert you if it is.
