McKinney Heating System Repairs – Thermostat Problems and Fixes


Every homeowner needs McKinney heating system repairs service when their furnace systems are not working properly. A malfunctioned furnace system can severely affect your home comfort and compromise indoor air quality.

If your furnace system is not functioning properly, it might be due to dirty filters, broken hoses, ignition issues, and thermostat problems. Sometimes, faulty and aging wires, temperature changes, and dust accumulation cause the thermostat to malfunction.

As a result, it does not communicate with the furnace. Although some of these issues can be caused by the furnace problems, the thermostat is always the first place checked by the McKinney heating system repairs service. Here are a few common thermostat problems. Read on!

Mismatched Components

The proper functioning of the furnace system requires matching the thermostat setting with the heating system. Experts at McKinney heating system repairs company advise homeowners to match their thermostat setting to their furnaces based on the type and capability.

Installing the wrong type of thermostat can cause miscommunication, which can result in system break down. Consult a professional McKinney heating system repairs company to ensure proper matching.

Faulty Wiring

Faulty, aged, loose, or missing wire connection can cause the thermostat to communicate with the furnace incorrectly. Not only do the defective wiring leads to loss of contact between the thermostat and furnace, but it also causes an interruption in proper airflow.

If the heating system is not working properly, call a professional service like Air Repair Pros. Our technician will inspect the wiring of the thermostat and tighten connections. Likewise, he or she will replace wires if necessary. Low-voltage thermostats have small-gauge wires, and you can’t work with them easily. So, a wise decision is to call a technician.

Dust and Debris

A dusty and dirty thermostat can significantly damage the furnace system. It can cause sudden system failure anytime, and if the problem occurs in the middle of a cold night, your home comfort will be compromised.

Remove the thermostat cover and clean its internal parts to resolve the issue. Otherwise, call a professional technician who will check and clean the switch contact surfaces and the bimetallic coil.

Our technician will start by setting the thermostat to its lowest setting. The technician will then use compressed air or soft brush to clean the internal components. Next, he or she will set the device to its highest setting and clean the coil. Likewise, our technician will reset the thermostat and set it to your desired temperature.

Heat Anticipator Issues

An analog thermostat has an electric resistor device mounted in the center. It is known as the heat anticipator, which informs the thermostat when to turn “ON” and “OFF” the burners. If it is not working properly, the problem of “ON” and “OFF” will be more frequent.

Moreover, digital thermostats come with built-in heat anticipators that work automatically. You don’t need to adjust it manually. However, if you have an older thermostat, you will have to adjust it manually.

A malfunctioned heat anticipator is one of the most common thermostat problems. It is not easy to adjust the heat anticipator, and you may need a professional McKinney heating system repairs service like Air Repair Pros to get the job done.

Inaccurate Temperature Readings

It is one of the common thermostat problems. If the furnace does not turn “ON” or “OFF” correctly, it is due to an inaccurate temperature reading. First, it is crucial to check whether or not the device is installed in the proper location.

Generally, the thermostat should be installed away from outside windows, doors, and heat sources like radiant heaters and fireplaces. Exposure to direct sunlight, outside temperatures, and heat emission can cause the thermostat to read the temperature incorrectly.

Experts at McKinney Heating system repairs company recommend relocating the thermostat close the air return ductwork. That would allow the device to read the temperature accurately.

Another reason behind this issue is “drafts” that come from the wall cavity behind the thermostat. Find a void in the wall and fill it with insulation to limit the airflow. If the problem persists, call a professional technician, an expert who can find a suitable location for the thermostat.
