Thermostat Repair

Thermostats are essential components of an HVAC system. They regulate temperature based on the desired settings and help maintain a comfortable indoor environment. However, like any electronic device, thermostats can malfunction over time. 

Star’s thermostat repair services in Fishers, IN, and the surrounding areas can eliminate malfunctions so your thermostat is able to deliver the accurate temperature control you need at home.

Common Thermostat Problems

While thermostats are typically reliable, they can experience performance issues over the years. Here are some common problems to watch out for:

  • Thermostat not turning on: This is a common issue where the thermostat fails to turn on the heating or cooling system. It could be due to a problem with the power source, faulty wiring, or malfunctioning components.


  • Inaccurate temperature readings: This is when the thermostat displays inaccurate temperature readings, causing the heating or cooling system to run inefficiently. It could be due to a faulty thermostat sensor or a calibration issue.


  • Short cycling: Short cycling is when the HVAC system turns on and off too frequently, leading to increased energy consumption and wear and tear on the system. It could be due to a malfunctioning thermostat or dirty air filters.


  • Thermostat not responding to inputs: This is when the thermostat fails to respond to temperature changes or programming inputs. It could be due to a faulty thermostat display or control board.


  • HVAC system not turning off: This is when the heating or cooling system continues to run even when the desired temperature has been reached. It could be due to a malfunctioning thermostat or faulty wiring.


  • Batteries dying too quickly: This is when the thermostat batteries die too quickly, causing the thermostat to stop working. It could be due to a problem with the battery compartment or a faulty thermostat.


  • Wi-Fi connectivity issues: This is when the thermostat fails to connect to the Wi-Fi network or loses connection frequently. It could be due to a weak Wi-Fi signal or an outdated thermostat firmware.


  • Delayed response time: This is when the thermostat takes too long to respond to input commands, leading to discomfort and energy wastage. It could be due to a malfunctioning control board or wiring issue.

How Do I Test My Home Thermostat?

Before calling us for thermostat repairs, you can try some troubleshooting tips to identify the issue. Here are some steps to follow:

  • Check the power source: Make sure the thermostat is getting power. If it’s battery-operated, replace the batteries and see if that solves the problem. If it’s hardwired, check the circuit breaker and wiring connections.

  • Check the settings: Ensure that the thermostat is set to the right temperature and mode (heating or cooling). Sometimes, settings can get changed accidentally.

  • Clean it up: Over time, dust and debris can accumulate on the thermostat’s sensors and affect its performance. Use a soft brush or cloth to clean the surface and remove any obstructions.

If none of these steps seem to resolve the issue, it’s best to call a professional from Star Heating & Cooling to perform thermostat repairs.

When Should I Replace My Thermostat?

While most thermostat issues can be repaired easily, there are situations where it’s best to replace the unit altogether. Here are some factors to consider:

  • Age: If your thermostat is more than 10 years old, it may not be as accurate or efficient as newer models. Older thermostats also lack helpful features like programmable settings and Wi-Fi connectivity.

  • Constant repairs: Frequent repairs, even minor ones, can add up in cost and inconvenience. If you find yourself calling us often for thermostat repairs, it may be more cost-effective to get a new one.

  • Energy savings: Newer thermostats come with advanced features and technology that can help save energy and reduce your utility bills. For example, programmable thermostats can adjust temperatures automatically based on your schedule and occupancy.
