How long does a typical HVAC system last?

This question is best answered by looking at each common part of an HVAC system. A central AC unit, for instance, has an average lifespan of 15-20 years with proper installation and maintenance. Gas furnaces can last for the same period of time, and electric models tend to last about a decade longer. Heat pumps have an average lifespan of about 15 years, and ductless mini-split systems fall within the 10- to 30-year range. With regular maintenance, however, you can get more life out of the various parts of your HVAC system.

What is regular maintenance?

We define this as a customized maintenance plan that includes regular system tune-ups. We normally recommend at least two full tune-ups per year as each heating and cooling season starts. Our maintenance program also includes priority scheduling, service discounts, and the opportunity to schedule routine tune-ups or inspections at any time.

Why is SEER important?

Seasonal Energy Efficiency Ratio (SEER) is a way to measure air conditioner cooling output over a typical cooling season based on the energy usage in Watt-hours. It's important because it's used to determine maximum efficiency, information that can come in handy when choosing a new cooling system.

What can we do to address air quality concerns?

Occasionally having strong food odors in your home is usually no reason for concern. However, noticing increased respiratory symptoms or a decrease in the overall quality of your indoor air should be reason enough to find out what's going on. Fortunately, we offer a wide range of solutions that can help make the air in your living spaces more comfortable and healthy. Options we offer include whole-home humidifiers, air cleaners, and ventilation systems.

How often should filters be changed?

Clogged or dirty filters can also affect your indoor air quality. It's typically recommended that HVAC filters be changed once every month. Taking this step also helps your comfort system work more efficiently. You may be able to change your filter less frequently when you're not using your heating or cooling system as often.

How do I decide between repair and replacement?

Our answer will depend on several factors, including the age of your HVAC system, its overall condition, and the frequency and seriousness of repairs. One of our experienced technicians will take a look at your system and give you an honest opinion so you can make a decision that is right for your specific situation.

What about warranty repairs?

The extent to which any repairs to your unit may be covered by an existing warranty will depend on what the warranty specifically stipulates. Contact the manufacturer or builder that issued the warranty for additional information. Stellar Air Offers third-party extended labor warranties, as well.
