The thermostat is the most important component of a home heating and cooling system. It switches all of the other components on or off as required, so the desired temperature can be maintained. Without a quality thermostat, there is no way for residents to control the regulation of the temperature conditions inside a house. The thermostat allows for control of temperature settings, so comfort needs can be met effectively and efficiently. 



There are several types of HVAC system thermostats available on the market today. The most traditional thermostat is a non-programmable, manual type. They have fallen out of use due to the availability of other thermostat types which are usually more energy-efficient, require less maintenance, and offer greater control. Some other types of thermostats are programmable ones; they can be preset to regulate daily or weekly temperatures. WiFi thermostats are also available. They are also programmable but connect to a wireless network, so they can be accessed via a smartphone app or a computer. Another type is a smart thermostat, which is similar to Wifi-enabled types: it can be accessed from any device that has an internet connection; but it also can be integrated into a home automation system. They “learn” patterns of use by residents over time and can eventually adjust temperatures accordingly.



A faulty thermostat will cause a home heating, ventilation, and air conditioning system to function improperly and inefficiently. It must have working batteries and needs to be cleaned of dust and debris regularly throughout its lifespan. Checking these things consistently is important to keep the thermostat in working order for as long as possible, and it allows for any other issues to be discovered before they turn into huge problems. Both thermostat age and the development of defects over time play into its faultiness, resulting in temperature inconsistency and inaccuracy. For instance, a thermostat can malfunction due to defective or damaged wiring or blown fuses; and incorrect calibration can cause a thermostat to fail as well.



Thermostats should be replaced when you replace your HVAC system, or if they are older than about 10 years–advances in technology mean that an upgrade will yield greater efficiency, allowing for savings on energy bills and more effective use of your heating and cooling system. If you have a traditional analog thermostat, you should consider replacing it with a digital model at least.
