Written by HVAC Link

Efficient heating and air conditioning are an essential part of the comfort level in your home. When your HVAC system isn't working properly, it can lead to general discomfort, elevated utility bills, and other issues that affect the health of everyone living in your home. If you're having issues with your furnace or air conditioner, it helps to understand these HVAC issues to determine whether the issue is something you can resolve yourself or if you need the help of an HVAC professional. 

1. Home Thermostat Not Working 

When your furnace or AC isn't functioning properly, it's common to worry that the problem is within the HVAC unit. However, your home thermostat could provide an easy solution to your issue. There are many types of thermostats, both programmable and non-programmable. When your thermostat isn't set properly or is malfunctioning, your system won't behave properly. If your HVAC system doesn't activate when it should or seems like it's working overtime, it's a good idea to refer to your owner's manual and review the operating instructions for your thermostat. Often, the solution can be resolved by resetting the thermostat or replacing the batteries. 

2. Dirty Filters 

The filters in your HVAC system carry a heavy load. Just like everything else in your home, these filters become dirty. Routinely replacing your HVAC filters is the best way to extend the life of your system and keep it working efficiently. Common signs of dirty HVAC filters include: 

  • Poor airflow 
  • Your system running for longer periods of time or turning on more frequently 
  • Your furnace shuts off suddenly because it overheats 
  • Strange sounds coming from the unit or ductwork

3. Ductwork Problems 

Your HVAC system is composed of ducts that supply the rooms in your home with cooled or heated air. If these ducts are damaged or clogged, your furnace or AC won't work in the way it should. Over time, ductwork issues can lead to problems with the unit or increased utility bills. Some common issues that occur in the ductwork of residential HVAC systems include leaky ducts, clogged ducts, or broken components that prevent proper airflow direction. If you're experiencing ductwork problems, it will be difficult to pinpoint the problem on your own. However, you may notice limited airflow to a specific vent, airflow that is the wrong temperature, or rooms that are hot or cold. Make notes of these issues and let your HVAC technician know.  

4. Faulty Power Source 

A furnace or AC that won't turn on is one of the most concerning experiences you can have with your HVAC system during extreme weather. To determine whether there's an issue with your system, it's important to know if your HVAC unit is receiving adequate power. Begin by visually inspecting the cord to ensure there's no damage and that the unit is properly plugged in. Other issues that prevent power from reaching the outlet that powers your HVAC system include blown fuses and tripped circuit breakers. If your HVAC system isn't receiving adequate power, it's crucial to contact an experienced professional to troubleshoot these issues.  

Your HVAC system is an important investment that plays a big part in the comfort level of your home. Keeping it properly maintained can help you extend its lifespan and avoid expensive repairs. While you can take care of filter changes, ensure your unit is properly plugged in, and resolve common thermostat issues, it's crucial to contact an experienced HVAC professional to address system repairs.
