Has Your AC Broken Down Recently? 4 Causes

During the hot summers, your AC will constantly run to keep your home cozy. That said, running your AC non-stop can strain it or subject it to a system malfunction. An AC breakdown will result in decreased efficiency, uneven cooling, and loud noises. Moreover, if the damage is extensive, it can render the AC inoperable—requiring a replacement. If you're dealing with an AC breakdown, hire a repair expert to remedy the problem and perform tune-ups for optimized operation. The following are the reasons behind your AC breakdown.

Dirty Air Filter

An air filter removes dirt, dust, and debris from your AC. When debris and other airborne particles clog the filters, they form a blockage that impedes airflow into the system. Limited airflow causes a ripple effect on other components and can lead to evaporator coils freezing up or compressor failure. If your air filters are disposable, a home appliance service repair technician should replace them once they are used up. Conversely, if they are reusable, the expert will clean out dirt and debris build-up to restore sufficient airflow in the unit.

Refrigerant Leaks

If a refrigerant line springs a leak, it may cause the reduction or depletion of the refrigerant. Low levels can limit heat exchange since the refrigerant aids heat transfer as it circulates through the evaporator coils. This causes the AC to work too hard to cool, forcing warm air to flow through the vents. Therefore, when you hear a hissing noise from your indoor unit, contact an AC technician to perform a leak test and regas the coolant to restore efficiency.

Dirty Condenser Coils

Condenser coils are housed in the exterior unit and eject heat from your home. The outdoor unit is susceptible to elements such as seasonal debris and lawn chippings as it is exposed to landscaping maintenance activities such as pruning and gardening. Debris build-up causes the unit to overheat, which triggers the system lock mode. An AC expert must regularly service your unit to clean debris build-up on the condenser coils for effective heat transfer.

Thermostat Malfunction

A thermostat displays the ambient temperature and allows you to adjust it to desired settings. If the thermostat has a build-up of dirt and grime, it will not detect the temperatures correctly. Moreover, if the fuse inside your thermostat blows up, it will render the unit unresponsive. Therefore, you must call your home appliance service technician to clean the thermostat, replace the blown fuse and ensure that it is in the right setting.

AC repairs and replacements can be costly, especially if they keep recurring. To avoid such expenses, ensure a home appliance service repair technician performs routine tune-ups, inspects your unit, and addresses any issues before they escalate.
