How Long Should My HVAC System Last?

There are numerous factors that impact how long your heating and cooling system will last, including the make and model, whether or not it received regular maintenance, how frequently it is used, and much more. However, on average, homeowners can expect their heating and cooling system to last around 15 years.

How Frequently Should I Get Maintenance Service On My Heating & Cooling System?

Most systems are best served by bi-annual checkups – one in the fall before the chill sets in, and one in the spring before things really heat up. Not only will this serve to ensure that your system is ready to take on the coming season, it will also help you to identify any potential problems and address them before they become larger, more costly issues.
