When To Replace the Thermostat

How To Know When To Replace a Thermostat

Thermostats are not designed to be used indefinitely. Typically the average thermostat only lasts ten years. Once a thermostat is inaccurate, homeowners experience fluctuating temperatures and expensive power bills.

The Cost of a Broken Thermostat

An HVAC system is essential in Texas to keep indoor areas cool. Broken thermostat symptoms can affect health as well as comfort. Consistently hot spaces are not tolerable for the elderly and may be dangerous in urban areas.

If a thermostat is set at 70 and the temperature still feels excessively warm, this is just one of the signs of a broken thermostat. Essentially this means the HVAC system is working harder than normal just to provide a comfortable air quality.

An accurate thermostat helps homeowners gauge how much their electric bill will cost. Inaccurate thermostats may gradually increase the power bill over several months instead of weeks. Keeping a log helps homeowners spot higher energy bills during the summer to have a firm understanding of the average monthly cost.

Faulty Readings

Inaccurate thermostat readings can be due to age, malfunction, or location. Regardless, it is important to investigate the issue so that the HVAC system is not affected.

If a thermostat is not level, it can display an incorrect temperature. This usually happens with older thermostats that have dials instead of digital numbers. Improper installation will cause an inaccurate reading but can be readjusted or reinstalled by a professional.

The actual location is also important. Thermostats need to be positioned in a central location. Ideally, this is near a draft where optimal shade is available. Placing an older thermostat directly in the sunlight may immediately alter the reading.

The sensor frequently causes a malfunctioning thermostat. A trained technician will help calibrate the thermostat, but it may need to be replaced anyway. With professional help, homeowners can understand which solution works best based on the underlying cause.

To verify a thermostat is correct, tape a glass tube thermometer next to the thermostat. After an hour, the glass tube thermometer and the thermostat should read the same temperature. If they do not, the thermostat is inaccurate.

What Is Short Cycling?

Short cycling happens when an HVAC unit unexpectedly turns on and off at regular intervals. If the thermostat is incorrect, an HVAC unit will not be able to reach the set temperature. Instead, it will work based on a faulty reading.

An HVAC system will eventually stop working by turning off and on too frequently. Short cycling includes increased energy bills, inconsistent temperature, and loud noises. Although a faulty thermostat is usually the culprit, only a trained technician can diagnose the problem.

Short cycling has an impact on both winter and summer. The HVAC unit cannot provide a consistent temperature indoors by failing to complete a full cycle.
