Should You Replace Your HVAC Thermostat This Fall?

October 11, 2022

The efficiency of your HVAC system depends greatly on the quality of your thermostat. So, if you want your HVAC system to run more efficiently this fall, you may need to upgrade your thermostat. Here are five signs that you need to replace the HVAC thermostat for your home in North Las Vegas, NV:

Faulty Readings

If your HVAC thermostat isn’t displaying the correct temperature, it needs replacement. This could mean that your air conditioning system is working harder than necessary to maintain your home’s desired temperature, resulting in higher energy bills. A faulty thermostat could affect the efficiency of your HVAC system, so it’s best to get a new one as soon as possible.

Old Age

The average lifespan of an HVAC thermostat is about 10 years. If your thermostat is older than that, it’s probably time for a replacement. Newer thermostats are more accurate and can help you save money on your energy bills.

Temperature Fluctuations

If you notice that the temperature in your home fluctuates even when you set the thermostat to a specific temperature, it’s time for a new thermostat. It indicates that your current thermostat isn’t working properly. Get a new programmable thermostat that will allow you to maintain a consistent temperature in your home.

Strange Noises

Your thermostat shouldn’t make any noise. If you notice any strange noises coming from your thermostat, it’s a sign that it has problems that need immediate attention.

Ask one of our service technicians to check and correct the problem. If the noise persists, however, it indicates that your thermostat needs replacement.


Short-cycling in thermostats occurs when they repeatedly turn on and off. This could be due to a faulty sensor or loose wiring. If you notice your thermostat is short-cycling, it’s a sign that you should replace it.

If you notice any of these signs, it’s time to replace your HVAC thermostat to improve the efficiency of your heating and air conditioning systems.
