Find Out Why Your AC Is Not Working

You will find that almost all homes have an air conditioner to beat the heat. Hence, given this crucial task and continued use, your AC will experience wear and tear over time. This will decrease the system's functionality, force it to consume more energy, and make the unit prone to breakdowns. You should know that by neglecting to address the issue, you may experience premature system failure that may necessitate a replacement. Thus, you should employ the services of an AC repair expert to remedy the underlying malfunction. Below are the reasons your AC is not working.

Old or Defective Thermostat

If you have an outdated dial control thermostat, it may fail to start your system. This happens due to incorrect calibration, which causes the AC to receive erroneous instructions. In addition, a faulty thermostat sensor may cause inaccurate temperature detection, causing the system to run in premature cycles. Finally, a huge discrepancy between the room temperature and the set point may cause the unit to run in overdrive. This will force it to wear down faster and fail. Therefore, replacing an old and outdated thermostat with a smart installation is best to ensure proper function and energy savings. 

Blocked Outdoor Unit

The outdoor unit allows the refrigerant to expel heat outdoors. However, the condenser is vulnerable to infiltration by outdoor elements. Over time, plant matter and debris may obstruct the condenser, restricting heat release. In return, this will force the system to work harder to expel heat, causing the compressor to overheat. As a result, the compressor may fail and render the unit inoperable. Given this, you must clean your outdoor unit to eliminate obstructions. In addition, ask an AC technician to raise your outdoor unit and give it adequate clearance for ventilation.

Refrigerant Leak

AC refrigerant draws heat from the air in the evaporator coil and dissipates it outdoors. That said, the lines carrying this coolant may degrade from formic acid corrosion and leak the refrigerant. Moreover, the fittings in the copper lines can become loose due to the condenser's vibrations, causing the refrigerant to leak. Consequently, you will hear hissing noises as the refrigerant escapes, resulting in diminished cooling output. With time, the refrigerant might deplete and restrict any cooling.

Electrical Failure

When your AC experiences an electrical malfunction, it may stop working. For instance, a power surge or short circuit will trigger the circuit breaker to prevent an electrical fire. As such, a tripped circuit will shut down your system and render it inoperable. Therefore, if you have noticed power surges in your home, call an expert to check your unit. They will fix the electrical malfunction and restore proper current flow.

When your AC stops suddenly, it may disrupt your indoor ambiance. Thus, you should book regular appointments with an AC repair contractor to perform maintenance checks on your unit. In addition, they will ensure each component is working as needed to prevent unexpected unit failure.
