As a Texas homeowner, you understand the importance of a reliable HVAC system, especially during the scorching summer months and freezing temperatures in the winter. 

If your heating, ventilation, and air conditioning (HVAC) system begins to fail, you should have a plan to make quick decisions and keep your home and everyone inside comfortable. 

This guide is designed to help you navigate that process. 

HVAC systems have a typical lifespan of 15 to 20 years if properly maintained.

*Reputable HVAC manufacturers should provide a 10 year parts warranty on the system's primary equipment. Labor warranties will vary based on the installing company.

PreFix recommends total system replacements for any system over ten years old due to limited warranties for partial replacements, such as replacing a condenser or a coil.

What does it cost to do nothing?

Older systems tend to be less energy efficient and can be difficult to repair due to a lack of available parts and antiquated technology.

Does your system use R-22?

R-22 is a refrigerant that is being phased out due to environmental concerns. When systems that use this refrigerant have leaks, the cost to homeowners can be enormous due to its scarcity - up to $200/lb.
