Potential Problems to Expect With Thermostats

Thermostats are the powerhouse of HVAC (heating, ventilation, and air conditioning) systems, as they control the temperature of a building or a room. However, like any other technology, thermostats are not immune to problems. If your thermostat develops issues, the entire HVAC system will be greatly affected with failure issues and may not even work at all. Thus, it’s important to know the issues that affect the proper function of a thermostat and know how to address them. As the tops AC repair techs in Coral Springs, FL, we at Air Pros see and troubleshoot these problems on a regular basis. Below, we share our expert knowledge on the most common problems to expect and what to do about them. 

Incorrect Readings

A thermostat that is giving incorrect readings can cause a lot of frustration, as it will result in rooms being either too hot or too cold. The possible reasons for these incorrect readings include: 

  • Incorrect installation
  • Dust buildup on the sensors
  • Power supply issues
  • Old batteries

We recommend addressing this issue by replacing the batteries and dusting the thermostat components. If you continue to get incorrect readings, you may need the help of an AC repair tech in Coral Springs, FL to further diagnose the problem. 

Inaccurate Temperature Control 

Aside from incorrect readings, you may also come across an issue where the thermostat is unable to maintain a consistent temperature throughout the home. Inconsistent temperatures are often explained by poor placement of the thermostat, clogged air filters, poor insulation, and leaky air ducts.

Inconsistent temperatures can be a sign that your AC is worn out. Check out our blog to learn more about the causes of a worn out unit. 

Compressor Problems 

Compressors are an integral part of any air conditioning unit. If they begin to have any failure issues, they will affect the proper function of the thermostat. Compressor-related issues that affect the thermostat include issues such as a clogged condenser coil, a faulty compressor relay, or even a blown fuse. 

In some cases, the compressor may simply be too small for your HVAC system, which can result in temperature control problems. Compressor problems are fairly critical to the health of the AC and must be investigated by an AC repair tech in Coral Springs, FL. Check out our blog to see if it may be time to replace the compressor in your unit. 

Battery Issues 

Many thermostats run on batteries, and if the batteries are dead or low, the thermostat will not be able to function properly. If your thermostat runs on batteries, it’s important to check them at least once per season and replace them as needed.

Wiring Problems 

In some cases, issues with the wiring between the thermostat and the HVAC system can cause problems with temperature control. These issues are often presented as frayed wires, loose connections, or broken wires. You may be able to visibly identify them if you carefully remove the thermostat from its placeholder on the wall. If you do see these wiring issues, we recommend contacting an AC repair tech in Coral Springs, FL for professional repair services.

Malfunctioning Fan 

A malfunction of the fan inside your evaporator can affect the performance of your thermostat. It can be caused by a clogged fan, a faulty fan motor, or broken fan blades. It is possible for your HVAC system’s fan to be too small, which can also cause temperature control issues.

Programmable Thermostat Issues 

Programmable thermostats can be a great way to save energy and money, but they are also subject to problems. Some of the most common issues with programmable thermostats include incorrect programming, incorrect settings, and malfunctions with the programming system. The good news is that if your thermostat was installed by a professional HVAC technician, these types of problems will be largely avoided.

Smart Thermostat Issues

A smart thermostat can be controlled remotely with a smartphone app. Though they are built with the best and most fool-proof technology, they too can develop problems like connectivity issues, incorrect readings, and software bugs. 

There may be some cases where a smart thermostat is incompatible with your HVAC system, resulting in poor temperature control. You may need to check the thermostat’s manual to see if it was built to support your specific unit. This issue can be resolved much quicker, though, if you have an AC repair tech in Coral Springs, FL help you out.
