Don’t let your AC unit compressor keep you from obtaining a cooler, controlled climate; contact us for solutions to overheating concerns!
The air conditioner is an incredibly complex unit, requiring many moving parts to operate properly. The compressor is just one of those. Unfortunately, many people don’t understand the intricacies of these systems, which may lead to homeowners asking questions like, “Why is my AC compressor overheating and shutting off?”
As the temperature rises, your air conditioner works harder to keep up with demands, overheating from overexertion and abruptly powering down as a safety precaution. But this is far from the only reason a compressor overheats. Below, our Coral Air Conditioning team explains the top five reasons for this Cape Coral issue.
1. Refrigerant Leaks Are Overheating and Shutting off Your AC Compressor in Cape Coral
The compressor circulates refrigerant for optimal heat transfer, pulling the liquid refrigerant into the evaporator coil so it can absorb heat from the surrounding air. After absorption, the coolant converts to a gas that the compressor pushes into the outdoor condenser coil. The compressor pressurizes the coolant so that it expels the heat outdoors, and the refrigerant returns to its liquid state.
Unfortunately, if you’re wondering, “Why is my AC compressor overheating and shutting off?” it could be because of lower refrigerant levels caused by leaks. Whether due to coil corrosion, weak electrical connections, or years of wear, less coolant means lower pressure levels, causing the compressor to work harder. AC maintenance professionals in Cape Coral, FL, recharge refrigerant levels while repairing coil leaks.
2. Dirty Coils Causing Your Compressor to Work Harder
Dirty coils have the same effect since a dust layer bars heat transfer. The filth insulates the coils, severing the contact between the heat from the air that travels over the coils and the refrigerant that runs within. The coolant absorbs less heat, lowering cooling capacity and causing the compressor to cycle the refrigerant more frequently.
Your Cape Coral air conditioner then takes long cycles, and the compressor works harder. Cleaning the coils helps eliminate the issue of dirty coils. However, the best way to keep from wondering, “Why is my AC compressor overheating and shutting off?” is by stopping filth at the source with proper air filters.
3. Filthy Filters in Cape Coral Causing Your Compressor to Overheat and Shut Off
Dirty air filters develop as airborne contaminants build up and break off of the meshy surface, allowing dirt to settle on all internal parts, including the coils. Filter buildups also reduce airflow, trapping hot air in the unit longer, leading to the compressor overheating and shutting down.
To prevent this from happening, clean your Cape Coral filters every three to four months with a gentle brush and warm, soapy water. Otherwise, replace them for better airflow and higher air quality.
4. Poor Cape Coral Ventilation Leading to Overheated Compressors
Just as your air conditioner needs optimal airflow from clean filters, it also needs proper ventilation to keep you from wondering, “Why is my AC compressor overheating and shutting off?” If your condenser unit, which houses the compressor, is in a tight space with limited airflow or a hot location, such as in the path of direct sunlight, it won’t function correctly.
So, clear the brush away from your outdoor Cape Coral unit to prevent clustering that creates heat. Also, install the compartment in a shady location away from the south or west-facing walls that receive the most sunlight.
5. Incorrect Cape Coral Compressor Sizes
Unfortunately, if you’ve been dealing with compressor issues since your unit installment, you may have an incorrectly sized compressor. Because living spaces are unique, each with different square footage and layout, cooling units come in different sizes to appease all homes.
A cooling unit or compressor that is too small for your home will have a long cycle, leading to deterioration and overheating. Similarly, an oversized unit leads to short cycling that turns on and off quickly, causing hot and cold spots and higher energy bills. So, have a Cape Coral professional measure your home and fit you with the appropriately sized unit.
