4 Common Causes Of HVAC Issues

Posted on

An HVAC system manages the air inside homes, but it's easy to forget about it until a problem arises. However, there are many causes of HVAC issues that you may be ignoring. If you would like to know more, keep reading.

1. Lack of Maintenance 

Lack of maintenance can lead to many HVAC issues, including:

  • Dirty/damaged condenser unit
  • Dirty/damaged coils
  • Dirty/damaged fans
  • Lack of lubrication
  • Loose Parts/Screws

During a regular HVAC service visit, the technician cleans the system, lubricates it, and makes sure everything is tight. If there is damage, depending on the situation, the technician may even be able to fix minor damage. However, in most cases, this may require another appointment to ensure the technician has the time and parts.

Without regular maintenance, the system becomes less effective and less efficient. Not only can this shorten the life of the system, but it may lead to rising energy bills.

2. Ducts

Forced-air heating and cooling systems rely on ducts to transport the heated/cooled air to parts of the home. Unfortunately, these ducts can drastically reduce the effectiveness and efficiency of the system. First, damaged ducts with holes and gaps allow air to escape, so less reaches your living space. This forces the system to send more air before it can reach the desired temperature.

Second, ducts in attics and basements may lose some heat as the air passes through these spaces, which are colder than the rest of the house. Insulating these ducts can help prevent the transfer of heat.

Lastly, dirty ducts can't transport as much air as they should which reduces the efficiency and strains the system. 

3. Clogged Filters

Besides regular servicing, you need to maintain part of your HVAC system regularly: the filter. The filter catches any particles, but if the filter gets clogged, it can affect the airflow and create cold spots in the home. Plus, all that debris in the filter affects indoor air quality. If you have allergies or pets, you may need to change your filter more often.

4. Thermostat Problems

If your thermostat isn't working well, it's hard to accurately control the system. If your thermostat is old, it may no longer read the temperature correctly. Similarly, if your thermostat is near a heat source, it may think the house is warmer than it is.

Even if the thermostat works, upgrading to a smart thermostat can help save you money. With a smart thermostat, you can program it to automatically turn off when you aren't home and/or when sleeping.
