The thermostat is the brain of every HVAC system. This small device controls all parts of the said circuit, and with it, you regulate performance such as room temperature and humidity. Due to the complexity of the operation of this small device, failures on it are not uncommon.
Even the slightest malfunction can affect the operation of the entire system. Fortunately, these issues are often harmless and easily solvable. Calling experts like ABC Heating & Air Conditioning, Inc is always a good solution, but you can also troubleshoot most of these issues yourself.
No Power
If your HVAC system doesn’t work, make sure the thermostat is lit at all. In case it can’t be turned on, check if the batteries are fully charged. There may be a problem with the blown or broken fuse or tripped switcher in the main service panel.
Dirt Deposits
If the problem is not with power input, see what happens inside the control panel. Shut it off and take off the cover. You’ll see if there’s any dirt or dust. Even grease and cigarette smoke can build up inside. These deposits can affect a thermostat’s functioning and connections inside it.
Clean this small device from time to time. Don’t use water and cloth, but canned compressed air or a soft-bristled brush. Also, make sure this tiny circuit is not exposed to direct heat or sunlight. The thermostat can estimate the wrong temperature inside your home and mess up the system operation.
Check the Settings
Manufacturers recommend merely adjusting the temperature that the thermostat is regulating so that it matches the current temperature in the house. If it’s not positioned at the right level, this device may set the wrong temperature. That can cause the system to short-cycling or make it work all the time to reach the set temperature.
Neither of these situations is desirable. It means that your system works, but it’s not efficient. HVAC will use a large amount of energy to maintain a comfortable temperature, which will make your bills go up. See if the wrong sitting is the problem by adjusting its level.
Faulty Wiring
The last reason why the HVAC thermostat doesn’t work is faulty wiring. Sometimes, the wiring will become slightly messy, and it will interfere with the functioning of the control panel. You can suspect this problem if this device is unresponsive and the problem is not about the power source.
If the wire inside the system becomes dirty or damaged somehow, then it will prevent the thermostat from working properly. To fix this problem, you will need to have your heating and cooling system serviced by a professional. Once you do this, you will be able to enjoy comfortable and convenient rooms with pleasant temperatures and fresh air.
Outdated Thermostat
Each device has a shelf life. If your HVAC system has an outdated mechanical thermostat, there is a higher chance that it will break down more often. The simple solution is to replace this small circuit with a newer model. It’s a cheap investment and can save you many problems.
Newer models are digitized and programmable. They have many options that will make it easier to anticipate and set the temperature in your home. Some devices have the ability to connect to Wi-Fi, so you can control them through your smartphone even when you’re not at home.
Most breakdowns related to the HVAC thermostat can cause indirect troubles in the performance of this system. These problems are usually not big and complex, but since they interfere with the proper functioning of the system, they should be resolved in a timely manner.
