AC Repair Services in Cottleville

Air conditioners work very hard during the hot St. Louis summers.   Even the most high-end systems can experience an untimely break down.  Faulty wiring, falling debris, refrigerant leaks and many other factors can lead to mechanical break downs.

While some issues can easily be identified, others can be more difficult to diagnose. Before attempting to address the problems yourself, which can worsen the issue, trust in a professional. Our expert technicians can repair and maintain your air conditioning system ensuring that your air conditioner is running at its peak efficiency.

Refrigerant Leak

Without regular maintenance to your home’s AIR CONDITIONING system, small issue can become a larger one. One such issue many residents in Cottleville see is refrigerant leaks. The refrigeration system of your AC is a closed circuit and should not require additional refrigerant unless there is a leak.  The leak can be found in a number of places; the evaporator coil, the condenser coil, or anywhere between.  When a leak is present there are several options but only one solution.  The solution is to repair the leak or replace the failed part.  The band aid is to charge the system with refrigerant, if the leak is small the unit may run without error for the rest of the season.
