You most likely have a heating, ventilation, and air conditioning (HVAC) system in your home if you live in an area with extreme temperatures. Any breakdown that happens to your system can be costly and inconvenient. There are many reasons an HVAC system might break down; some are more common than others. This blog will discuss 5 causes of HVAC breakdowns and how to prevent them.

1. Clogged Filters

Air filters help remove dust, dirt, and other airborne particles from your HVAC system. Clogged filters cause your system to work harder than it has to and can lead to a breakdown. Reasons for filter clogging include:

  • Not changing the filters regularly
  • The wrong type of filter
  • Having pets that shed

The best way to prevent this is by regularly checking and cleaning your filters. Follow how often to replace the filters recommended by the type your HVAC system uses.

2. Malfunctioning Thermostat

Thermostats are designed to last for years, but like anything else, they can malfunction. A broken thermostat can cause your system to run constantly. You can prevent a breakdown by:

  • Regularly servicing your thermostat
  • Installing a new thermostat
  • Using a smart thermostat
    • Smart thermostats have features like remote access, automatic adjustments, and energy-saving mode that help you save money on your energy bills and prevent a breakdown

3. Leaking Refrigerant

Refrigerant is what makes the air in your air conditioner cool. Unsurprisingly, a refrigerant leak is the most common cause of AC breakdowns. Leaking refrigerant reduces your AC’s cooling power and can cause long-term damage to other parts of your HVAC system.

Some ways to identify and fix a refrigerant leak are:

  • Make sure all connections and hoses are attached properly
  • Ice on your AC unit means your refrigerant is low
  • Clean dirt and debris build-up from the coils and evaporator pan

4. Blower Motor Issues

The blower motor is vital for circulating air throughout your home. If the blower motor works incorrectly, your HVAC system won’t work. A few things can cause blower motor issues, like a problem with the electrical supply to the motor or a mechanical issue. If you’re having problems with your blower motor, it’s best to call a professional HVAC technician like Atlas HVAC, Inc. We can diagnose the problem and quickly get your system up and running. Blower motor issues can be prevented by:

  • Regularly changing the system’s air filter
  • Ensuring there is no debris around the blower unit
  • Keeping the area around the HVAC system clear

5. Lack of Preventive and Routine Maintenance

Preventative and routine maintenance help keep your system running smoothly and extend the life of your equipment. Preventive maintenance can include cleaning the coils and filters, checking the Freon levels, and other measures to keep your system running effectively. You can schedule routine maintenance with an HVAC company. Routine maintenance is an annual service agreement where an HVAC technician thoroughly inspects your system and makes any necessary adjustments or repairs.
