Common air conditioning problems

Here are the five most common air conditioning problems that homeowners experience during the summer months. Our cooling philosophy involves air quality, humidity, and temperature. When your air conditioning unit doesn’t seem to work optimally.

Drainage issues

Often water running from the main AC drain can backup and cause water overflow in the drain pan causing wet spots in your ceiling.

Inadequate maintenance

Dirty condenser coils and not changing filters can cause long term damage to the system, regularly scheduled maintenance can help preserve your system.

Leaking refrigerant

Evaporator coils in the attic or condenser coils can often leak over time and cause refrigerant to run causing warm air to run out of the system.

Electrical failure

Compressor and motors can wear out over time especially if the system is being turned on and off constantly.

Basic Operation of an Air Conditioning System

The best air conditioner is the one you don’t have to think about. It comes on the moment the indoor temperature set on the thermostat requires cooling performance, and then runs quietly and efficiently when needed. But when it’s time to perform routine maintenance, make repairs or replace your system, it’s helpful to understand how an air conditioning system works.

The Refrigeration Cycle

  • Using electricity as its power source, the refrigerant flows through a closed system of refrigeration lines between the indoor unit and the outside unit.
  • Warm air from the inside of your house is pulled into ductwork by a motorized fan.
  • The refrigerant is pumped from the exterior compressor coil to the interior evaporator coil, where it absorbs the heat from the air.
  • This cooled air is then pushed through connecting ducts to vents throughout the home, lowering the interior temperature.
  • The refrigeration cycle continues again, providing a consistent method to keep you cool.

Parts of a Central AC System

To get a better sense of how your air is cooled, it helps to know a little bit about the parts that make up the air conditioning system. A typical central air conditioning system is a two-part or split system that includes:

  • The outdoor unit contains the condenser coil, compressor, electrical components and a fan.
  • The evaporator coil, which is usually installed on top of the gas furnace inside the home.
  • A series of pipes, or refrigeration lines, connecting the inside and outside equipment.
  • Refrigerant, the substance in the refrigeration lines that circulates through the indoor and outdoor unit.
  • Ducts that serve as air tunnels to the various spaces inside your home.
  • A thermostat or control system to set your desired temperature.


  • Indoor comfort during warm weather – Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air – As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to rooms.
  • Quieter operation – Because the compressor-bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning
