Unsteady Thermostat Temperature

If your thermostat fails to maintain the set temperature, there’s a high possibility that the underlying cause might be one of the following.

Dusty Sensors

Thermostats employ temperature sensors to decide when to activate the heating and cooling system. Over time, dust, grit, and lint can obstruct these sensors, causing them to misbehave. A simple case removal and a gentle sweep with a soft-bristle brush can fix the problem.

Malfunctioning Sensors

If a thorough cleaning fails to resolve the issue, it’s likely that the sensors are damaged, giving you inaccurate room temperature readings. This situation necessitates professional intervention.

Improper Thermostat Placement

Is your thermostat located near a vent, a drafty window, or an area frequently basked in sunlight? If it’s providing faulty readings, it might need a professional recalibration.

Inability to Adjust Thermostat Temperature

After extensive research, our Colorado Springs HVAC experts have identified the following common causes for the inability to change your thermostat’s temperature settings.

Lock-engaged Unit

Check if the child lock is engaged. To adjust the temperature, it needs to be deactivated first.

Power Issues

A non-functioning thermostat could be due to a power problem. If this is the case, try replacing the batteries or checking the circuit breaker.

Faulty Wiring

Inconsistent thermostat operation could be due to defective wiring. Dismantle the unit and inspect the wires for rust, corrosion, or disconnection. If you spot any anomalies, it’s time to call an HVAC technician.

Heating and Cooling Systems Running Non-stop

Continual operation of heating and cooling systems can spell disaster for your HVAC system. Here are some common causes and their fixes.

Auto Fan Mode

Correct the setting. “Auto” mode keeps the fan running constantly. Alter the mode so that the fan activates only when the heating or cooling system is operational.

Faulty Thermostat

Internal thermostat malfunctions can cause this issue. Reach out to a professional for detailed troubleshooting and necessary repairs.

Blank Thermostat Screen

A blank thermostat can significantly impair your HVAC system’s functioning. Here are some common causes for this issue.

Expired Batteries

If your thermostat screen is blank, try removing the cover and replacing the batteries. If the display lights up, you’re back in business.

Tripped Circuit Breaker

A hardwired thermostat in a home could be affected by a tripped circuit breaker. If the breaker trips, resetting it should solve the issue.

Tripped Safety Switch

Identify the safety switch for your furnace or AC unit. If it’s been accidentally tripped, resetting it should fix the issue. However, if you observe unusual heat or moisture in the system, it’s prudent to call an HVAC professional for a thorough inspection.

Unresponsive Thermostat

If your thermostat refuses to turn on, several reasons could be at play. After extensive investigation, we’ve compiled the most common causes along with their respective solutions.

Incorrect Settings

Inspect your thermostat settings first. Set the dial to “heat” for warming your home and to a cooler setting for air conditioning.

Overheating HVAC System

If your HVAC system only operates briefly, it might be overheating. Improve ventilation by opening all windows and doors and replacing the filter. Bear in mind that air conditioners might take up to three minutes to restart to avoid compressor overheating.

Broken Thermostat

If you’ve tried all potential fixes and your thermostat still refuses to cooperate, it might be time to consider a replacement.
