Common Issues Your Furnace Can Experience

HVAC technicianRegardless of the age and brand of your furnace, without regular maintenance and checkups, you are at risk of a complete breakdown when you need heat the most. Also, without the necessary maintenance, your furnace will not reach its maximum lifespan which means that you would need to replace your heater earlier that you should need to. Also, a furnace that receives proper maintenance operates more efficiently, reducing your home heating costs.

Between maintenance checks, there are a few common signs of furnace problems that you should look out for. These include:

  • Persistent noises
  • Inadequate heat
  • Poor air quality in the home
  • Discolored pilot light
  • Tripped carbon monoxide detector

If you are unable to detect the signs that there is a problem with your furnace, it can cause serious health and safety hazards. If you run a malfunctioning furnace, it can result in a fire or carbon monoxide poisoning.

Furnace Repair Somersworth NH: Common Problems Your Furnace Can Experience

In this article, you will learn some of the common problems that can result in a furnace that doesn’t work properly.

Dirty And Obstructed Furnace Air Filters

dirty HVAC filterIf your furnace’s air filter is clogged or dirty, it can reduce the airflow in your home. It can also increase the amount of wear and tear on your furnace. These issues will make your furnace work harder than it should which will cause the furnace to become less efficient. It will also decrease the lifespan of your heater. To avoid these issues, you should change the filters regularly. Also, regular maintenance is essential.

Thermostat-Related Heating Issues

There are specific issues that can cause your thermostat to malfunction. These include wiring problems, dust and debris buildup, mismatched components, and incorrect calibration.

If the wiring is faulty, it could break the connection between the thermostat and the furnace. When this happens, the heater won’t turn off and on. If there is a break in the heat anticipator, it can cause the heater to short cycle.

Because the thermostat is a complicated piece of equipment, you should not make the repairs a DIY project. It will take an experienced HVAC tech to properly troubleshoot the problem and then repair it.

Problems With A Cracked Heat Exchanger In Your Furnace

gas furnaceThe heat exchanger is made of up a metal chamber and a passageway. This is the part that separates the combustion process from the air inside the home. It also keeps your home free of the toxic flue products such as carbon monoxide. The exchanger is covered with a thin sheet of metal. This metal can crack due to various factors such as rust, debris, and repeated exposure to moisture. This can cause serious furnace issues.

A crack can cause the hot air to stop blowing or for air to stop blowing altogether. Even worse, it can leak dangerous and toxic flue products into the house. To be sure that this doesn’t happen, you should contact a licensed HVAC tech immediately to replace the cracked exchanger.

Furnace Blower Motor: Problems & Causes

Forced air HVAC systems are designed to circulate conditioned air throughout the home. If the blower isn’t maintained correctly, it can result in a variety of malfunctions. There are a few reasons why the blower mower could fail. These include:

  • Dirt accumulation: When dirt and debris clog the blower motor, it can cause it to shut down.
  • Mechanical failure: If there are mechanical issues, the blower motor can fail. The bearing can wear out which can cause a malfunction. The same is true if the switch gets worn out. This will cause the blower motor to run constantly. If this happens, the blower will circulate cold air rather than conditioned air. If the belt drive wears out, the blower motor won’t start. Each of these issues can be prevented with regular maintenance checks.
  • Electrical failure: Electrical issues can cause the blower motor to malfunction. This can be caused by insufficient voltage to the capacitor and a variety of other reasons. Electrical issues can be complicated, and if you don’t know what you are doing, they can be dangerous. This is why you should hire a licensed HVAC contractor to diagnose and repair the problem.
