Understanding Air Conditioning Issuescommercial hvac repair philadelphia pa

There are many reasons why Philadelphia home’s air conditioner may need to be looked at by a certified Air Conditioning repair Philadelphia service provider, there are a few reasons that are fairly common.

Here are the most common problems that may cause your air conditioning system to break down. Please review these considerations and determine whether you need to call for service

Electrical wiring

Un-certified A/C wiring is risky and a possible fire hazard. Bad wiring can prevent the system from getting power or can trip the circuit breaker. The compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently, as is common when a system is over-sized. Because corrosion of wire and terminals is also a problem in many systems, electrical connections and contacts should be checked during a professional service call.

Refrigerant Leaks

If your air conditioner is low on refrigerant, either it was undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. A trained technician should fix any leak, test the repair, and then charge the system with the correct amount of refrigerant. Remember that the performance and efficiency of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer’s specification, and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment. To read about the phase out of R-22 refrigerant in the United States, we highly recommend you to visit the U.S. EPA website.

Outside unit not functional

This usually indicates a lack of power, contractor problems or even a faulty thermostat.

The coil is frozen

A frozen coil often indicates an issue with the airflow, such as restrictions caused by filthy air filters or obstructed return air duct-work. Frozen indoor coils could also be the result of low refrigerant.

Drainage problems

When it’s humid outside, check the condensate drain to make sure it isn’t clogged and is draining properly. Room air conditioners may not drain properly if not mounted level.


Best practices suggest that the most effective way for Philadelphia homeowners to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups.
