5 Signs You Need To Replace Your HVAC Thermostat

August 4th, 2021

Your thermostat is one of the most integral parts of your HVAC system. It monitors the current temperature of the air in your household and regulates the output of cold and warm air. A faulty HVAC thermostat can cause a variety of problems, and therefore must be at full working capacity at all times. 

There are many indications that your thermostat needs to be replaced. It’s essential to keep an eye on its functionality, especially at the beginning of our Hawaiian tropical climate shifts. Ultimately, your HVAC unit is what makes your home comfortable, and your investment should work for you, not the other way around. Let’s get started!

5 Signs That It’s Time To Replace Your HVAC Thermostat

Staying cool in the sweltering summer heat and staying warm in the chilling winter months are comforts that your investment in an HVAC unit should provide. At the center of these commodities is your thermostat. Take some time to become knowledgeable about the indications your unit’s thermostat needs to be replaced. Here we go!

1) Your HVAC System Turns On And Off By Itself

No one wants a system that has a mind of its own. This isn’t iRobot. The main function of your HVAC thermostat is to send signals to your unit to either decrease or increase temperatures. If your unit has stopped communicating with your thermostat, don’t blame it on your HVAC system. This is a sign that your thermostat has stopped working, most likely due to its wiring becoming frayed or damaged. Expert technicians are able to provide solutions for faulty wiring or wiring that has become damaged over time.

2) You’re Experiencing Indoor Temperature Shifts

When an HVAC thermostat isn’t functioning correctly, it has a hard time maintaining its settings. If you lower the temperature of your system and the output of cold air isn’t matching that of your thermostat, you may have a rogue AI. That’d be something, wouldn’t it? But no, if your cold air output isn’t matching the adjustment to a cooler temperature setting, it may be time to call a professional.

3) Faulty HVAC Thermostat Readings

When the thermostat for HVAC systems is working correctly, your living area will never be too hot or too cold. When your thermostat starts misreading temperatures, temperature shifts begin to occur, and it might be time for a replacement. Do a quick test, check your home’s indoor temperature with a separate thermostat, and compare it with your current thermostat for your unit. If the readings are different, it’s time for a replacement.

4) High Energy Bills

You may be experiencing an influx in kilowatt usage. Ask yourself if you’re altering the temperature of your unit more often. While your system may be working overtime, the thermostat could be the culprit of its insufficiency and your increased Hawaii utility bills. 

5) Your HVAC Thermostat Is Getting Old

The lifespan of most HVAC thermostats ranges from 10-15 years. We suggest replacing them as they get older and staying up to date on newer and modernized thermostats with more features. The latest technology will help to ensure that you’re taking full advantage of energy-efficient updates.
