Your AC unit’s thermostat is one of the most important parts of your entire cooling system. Think of the thermostat as the brains of the operation. And just like your own brain, when it gets frazzled or things go wrong, it affects the rest of the system (often in negative ways).
Let’s take a look at how a faulty thermostat could cause damage to your AC unit…
Short-Cycling: A situation that results in the cooling cycle turning on and off in cycles prior to each cycle fully completing. This results in frequent abrupt system cycling, putting a lot of strain and wear on the compressor, and resulting in increased energy bills.
Blower Fan Burn Out: A faulty thermostat may result in a constantly running blower fan that won’t properly cycle down, causing burnout and requiring repair.
Overall Inefficiency: A faulty thermostat may increase inefficiency of the units, causing ongoing wear as the system works harder to reach and maintain desired temperatures. This can significantly reduce the overall lifespan of the AC unit and may increase the risk of failures and downtime requiring repair.
