If you've ever wondered how long your HVAC system is going to last, you're like most homeowners. Knowing the average lifespan of an HVAC system is important because it helps you budget for a heating and cooling system replacement down the road. The length of time your HVAC system will last depends on the type of system you have as well as the maintenance you invest in. Here's a close look at different HVAC systems and their average lifespans in Crockett, Texas, home.

Furnace

The furnace used in a central heating and air system will likely last longer than the air conditioner, with an average lifespan of over 20 years. A furnace is normally replaced once the heat exchanger begins to leak. The heat exchanger is one of the most important components of a furnace, and once it goes bad, it's usually cheaper to replace the furnace rather than repair it. A furnace that receives little maintenance is likely to last only around 10 to 15 years.

Air Conditioners

An air conditioner that functions as part of a central heating and air system will last about 15 to 20 years. In warm areas where the air conditioner is operated on a frequent basis, the lifespan usually runs closer to the 15-year range. When the compressor fails on an air conditioner, this is usually a sign to replace the air conditioner. Plus, if the condenser develops corrosion or leaks, this is another sign that indicates a replacement of the AC should be right around the corner. Just like a furnace, an air conditioner that has little maintenance will have a shorter lifespan than one that is well-maintained.

Heat Pumps

The average heat pump can last anywhere from 10 to 20 years. Although they provide cooled air, heat pumps also provide heated air, meaning they are used on a year-round basis. This also means they are used much more frequently than the average air conditioner and do not last nearly as long as air conditioners. When used in coastal areas, a heat pump has an even shorter lifespan.

Ways to Extend the Life of Your HVAC System

There are several tips you can follow to help extend the life of your HVAC system. First and foremost, you should invest in regular HVAC maintenance. During a maintenance appointment, a certified technician will inspect all parts of the heating and cooling system. If any parts are worn or damaged, the technician will repair or replace them as needed. This is very important to the efficiency and lifespan of the HVAC system. With each part performing with full functionality, you'll notice improved indoor comfort. Better efficiency also results in lower heating and cooling expenses.

Another way to extend the life of the HVAC system is to change the air filter on a regular basis. This normally means changing it once every 2 to 3 months. A clogged filter hinders airflow and makes the HVAC system work harder than necessary to heat and cool your home. As it works harder and consumes excessive amounts of energy, this increases your heating and cooling expenses. It also puts added wear and tear on the system and decreases its lifespan.

You can also help extend the lifespan of the HVAC system by taking special note of your home's landscaping. Ideally, trees and shrubs should shade the western exposures of your house. Any trees and plants near the outside HVAC unit should be at least three to five feet away. When plants or shrubs touch the outdoor unit, this can lead to damage to the unit, decreasing its lifespan.
