Why do HVAC Systems Fail?

There are several factors that may lead to the failure of a home HVAC unit. Regular maintenance is a vital factor to improve the functionality of a unit, extend the life of the system and catch any problems before they become too great for repair.

Here are four of the most common reasons HVAC system fail:

Debris
Heat pumps require about 18 to 24 inches of breathing room to operate properly. Even outdoor AC units require freedom from outdoor dirt, leaves and plant growth. Unkempt and dirty outdoor units can fail if they are full of debris.

Faulty Installation
Quality HVAC professionals know that proper installation is part science and part art. Technicians who fail to take the time and care to install your system correctly can cost you up to 30% in lost efficiency. That means your system works harder and often “dies” before its time.

Lack of Regular Maintenance
The failure to properly maintain your HVAC system can lead to many more serious problems, including leaks. A leak in your system will cause it to work much harder to maintain your home’s temperature. This not only puts extra stress on its parts and reduces the life of your system—it also increases your utility bills.

Improper Sizing
An HVAC system shouldn’t be too large or too small to maintain temperature in your home. The wrongly sized unit is one more way to over tax your system and reduce the lifespan.
