5 External Factors Affecting the Lifespan of Your HVAC Unit

There are few things more frustrating than returning home from work on a sweltering summer day or a chilly winter evening, only to discover your HVAC system isn’t working properly. A malfunctioning HVAC system not only fails to cool/heat properly, it also consumes more electricity. If you ignore HVAC issues, they can get worse and your unit may break down earlier than you anticipated.

Regardless of the type of HVAC system you have, come up with a plan to manage these external factors that can affect HVAC performance and lifespan.


Local climate and the location of your HVAC system can affect its lifespan. If you live in an area that experiences dry conditions, dust and debris can gather around the unit’s coils and filters more quickly. To prevent problems, check your coils for dirt and dust at regular intervals and change HVAC filters every 30-90 days or sooner if someone in your family has a seasonal allergy. Keep the outdoor unit free from obstructions and trim vegetation around it to prevent airflow problems.


If your home’s humidity levels increase or decrease more than normal, your system may have to put more effort. HVAC systems that are forced to work longer are under a lot of strain and can break down anytime.

Lack of Maintenance

Over time, the parts of your HVAC system can deteriorate or break, causing it to malfunction or even stop working. Make preventive HVAC maintenance a top priority. Have a professional maintain your HVAC system once a year.

Like every other household appliance, HVAC systems need regular maintenance. Periodic professional maintenance addresses current problems in a timely manner and prevents potential issues to keep your cooling and heating system in Sacramento running at their peak efficiency. During maintenance sessions, your HVAC contractor replaces air filters, cleans coil, inspects the outdoor unit, tests electrical connection and lubricates parts to reduce wear and tear on them.

Run Time

HVAC systems that run continuously experience more wear and tear. Accelerated wear and tear can affect a unit’s performance and reduce its useful life. In many cases, airflow problems force HVAC systems to work longer and harder. To prevent airflow problems, replace your HVAC filters and perform other maintenance tasks regularly.

Use a programmable thermostat instead of a manual thermostat. On warm summer days, keep your curtains closed during the day to block the sun’s rays so your HVAC system is not forced to go into overdrive to maintain your desired house temperature. Use fans to ensure the conditioned air is circulated effectively throughout your home.

Installation Quality

Improper HVAC installation can lead to several problems that can affect your system’s efficiency and reduce its longevity. Hire a professional for HVAC installation. HVAC experts have the knowledge, skills and experience to ensure a flawless installation every time.
