Is It Time to Replace Your HVAC System’s Thermostat?

The HVAC thermostat is the primary mechanism that controls your home’s comfort. Yet, they don’t last forever. Is it time for thermostat replacement in your Goshen, IN, home? Here are some signs it’s time to call a qualified service technician.

The Thermostat Is 10 Years Old or Older

The average lifespan of an HVAC thermostat is roughly ten years. After a decade, thermostats show their age and signs of wear and tear. Faulty sensors are the most common problem in older thermostats.

The HVAC System Runs Continuously

Have you noticed that your heating or cooling system runs nonstop or longer than usual? Faulty thermostat wiring can cause the HVAC to run nonstop. When the system runs nonstop, your energy bills will skyrocket—but that’s not all. If the system’s fan runs continuously, eventually, it overworks the entire system.

If the system starts and stops before completing a full cycle, also called short-cycling, the thermostat likely has a failing temperature sensor. Although short cycling doesn’t necessarily affect comfort, you don’t want this problem to continue because it will shorten the HVAC system’s lifespan.

Short-cycling and continuous running are no good for your heating and cooling system. Allowing these problems to continue eventually results in a damaged HVAC that will cost more than thermostat replacement. So have a qualified technician check out the problem ASAP.

Why Thermostat Replacement Is the Best Option

A broken thermostat is almost always better off being replaced, especially if it’s over ten years old. Not only is it more cost-effective to replace a thermostat than repair one, but if you still use a manual thermostat, chances are it’s reading the temperature inaccurately. New digital thermostats, particularly programmable thermostats, do a much better job maintaining indoor temperatures and keeping you comfortable in your home.
