Why Do Air Conditioners in Highlands Ranch Short Cycle?
Though you can cool down rooms at your Highlands Ranch home or business with fans or open windows, air conditioners do a great job of regulating indoor temperatures in the summer. Unfortunately, air conditioner short cycling is a common symptom of several equipment-related problems.
Short cycling occurs when a cooling unit turns on and off within a minute or two. Though air conditioners have an “auto” function that triggers their on-and-off operations according to indoor and outdoor temperatures, normal cycles should last several minutes.
If a cooling system is short-cycling, it’s experiencing an underlying problem that’s preventing it from working efficiently. As a result, your property could have increased energy bills, humidity, and general discomfort.
Reasons Your Air Conditioner Could Turn Off By Itself
Do you want to know, “Why does my air conditioner turn off by itself?” The answer will depend on your specific situation. Yet, the following factors are the most common culprits behind air conditioning short cycling.
Clogged Air Filter
Dirty air filters might not seem like a major problem, but they can be. Air conditioning filters will trap airborne debris every time the system cycles on. Unfortunately, these filters aren’t self-cleaning and can quickly clog with hair, dust, dirt, pet dander, and other allergens and contaminants.
A clogged air filter will restrict airflow, which can lead to overheating. In this case, short cycling becomes a safety mechanism to prevent the air conditioner from breaking down entirely.
Malfunctioning Thermostat
When a thermostat malfunctions, it can appear as though your HVAC system is defective even when it’s not. Your cooling system relies on a thermostat to initiate its operations, so any malfunction can cause the air conditioner to get the wrong signals or no signals at all. When that happens, short cycling can occur.
Sometimes, thermostats use batteries as a primary power source. Always check your device to ensure it’s getting sufficient power. It also needs proper calibration, which an experienced HVAC professional can handle.
Electrical Issues in AC Unit
Loose electrical connections and damaged wiring can also cause your air conditioner to turn off prematurely. Even tripped circuit breakers can affect HVAC performance. Electricity is too dangerous to handle yourself, so contact a skilled professional to check for electrical problems.
Overheating Compressor
An air conditioner compressor is responsible for ensuring refrigerant flows through the unit. The refrigerant is essential for removing heat and moisture from indoor air. Since refrigerant circulates through various coils on a closed loop, a leak will create many problems including an overheated compressor.
Running your air conditioner without sufficient refrigerant will cause the compressor to overwork itself to compensate for the loss and accommodate the thermostat’s temperature settings. A warning sign of a refrigerant leak and overheating compressor is short cycling. Still, you’ll need a technician to inspect your system to pinpoint the problem.
