When to Replace Your Home Cooling & Heating System

How do you know when to replace your Air Conditioner or Furnace?

Here are a few general guidelines.

One of the biggest decisions when it comes to your heating & cooling system is deciding if you should invest in a new system, or fix your current system and hope to get a few more seasons of use from it. We know this decision is very important, and sometimes the urgent nature of the matter (ever have an air conditioner fail on the hottest day of the year?) can put even more pressure on you.

Fortunately, some general guidelines have been established to help homeowners with determining when to replace your Air Conditioner or Furnace.

Below are some general rules for when it’s time to replace from EnergyStar.gov:


  • Your system is more than 10 years old – This is the normal life expectancy for heating & air conditioning equipment. After this time, repairs generally don’t make sense when compared to the cost of a new system. In addition, upgrading to a newer, more efficient system can save significant money on your utility bills.
  • Your equipment needs frequent repairs and energy bills are going up – These are the tell-tale signs that it’s time to invest in a new heating & cooling system that can provide a higher, more stable level of comfort as well a reduced energy bills.
  • No one is home for long periods of the day and you do not have a programmable thermostat – A modern system with a programmable thermostat can keep your energy bills low, while still ensuring you are comfortable while you are home.
  • You experience humidity issues or problems with excessive dust – Older equipment and leaky ducts can cause these problems – Meyer & Depew can install new equipment as well as offer solutions for humidity and indoor air quality issues.
