Air Conditioning

Condensate Drain Line

An air conditioner’s evaporator coil produces condensation that must be drained off of the system. The condensate drain line serves the purpose of channeling the moisture away, but the wet environment naturally tends to nurture algae and mold growth. Without regular cleaning, organic matter can build up in the drain line and clog it, resulting in higher humidity levels and even noticeably musty odors in the house. Unchecked, severe obstruction of the drain line can ultimately cause expensive water damage to your home.

Pledge: We will check the condensate drain line and clear any obstructions.

Relays and Contactors

Your thermostat and cooling system communicate by means of a chain of electrical connections. Along the chain, relays and contactors serve as switches, engaging and disengaging the compressor and condenser fan according to how you’ve set the thermostat. The flow of electrical current through the contactors and relays tends to wear out the components over time, leaving pits and scarring. Not only can the contactors and relays themselves fail, but loose wires and worn contacts can also lead to failure of the condenser fan motor and compressor.

Pledge: We verify that the relays and contactors remain fit for continued operation.


While your cooling system produces cool air, the electric motor that produces it can run for a long time and itself produce heat. The insulated wires may break down after exposure to the hot internal compartments of the system, leading to loose and exposed wires. Electrical shorts may result and have the potential to start fires, which is why cooling systems are set to trip the circuit breaker upon the detection of a short. If your cooling system is tripping the circuit breaker, it is a sign that you may have loose and exposed wires in the system. Left unattended, the electrical shorts may also lead to motor and compressor failure, so we make it one of our priorities to check the wires and replace them when we see wear.

Pledge: We will inspect the wiring and replace any wires with worn insulation.

Unit Disconnect

Disconnects are electrical safety features that ensure the heating and cooling system is completely shut off during servicing. A number of factors can compromise the disconnect and the wires connecting it to the rest of the system, including water, rust, overheating and general wear. The condition of the disconnect determines its effectiveness as a safety measure, consequently any deterioration represents a danger in itself. Moreover, decay of the disconnect may lead to blown fuses.

Pledge: We will inspect the disconnect.
