When to Replace Your HVAC System

It can be difficult to know when your HVAC system should be replaced. There are a number of signs to look out for, but the only way to know for sure is to have an expert examine your system and make a careful evaluation.

Some of the most common signs that it's time to replace your HVAC system include:

  • Your energy bills have been steadily increasing over the past few months
  • Your HVAC system is over 10 years old
  • Your system runs for a long time but doesn't seem to be able to keep your house cool
  • Your system is making loud noises, such as rattling or banging
  • Your system requires frequent maintenance or emergency repairs

The Importance of Scheduling Maintenance

HVAC systems are designed to last for many years, but they will eventually need to be replaced. Proper maintenance can help extend the life of your system, saving you money on repairs and energy costs. HVAC systems that receive regular maintenance are also less likely to break down suddenly, which can cause major disruptions to your day and your home.

We recommend scheduling maintenance twice a year:

  • In the spring, before the start of the cooling season
  • In the fall, before the start of the heating season

During these appointments, our technicians will inspect all of the mechanical and electrical components of your system, test the airflow, clean the filters, and make any necessary adjustments. We will also advise you on how to care for your HVAC system and help you avoid maintenance-related breakdowns.
