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.

Wiring

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.

Condenser Coil Cleaning

Over time, the condenser coils of your air conditioner accumulate dirt and debris. As the coils get dirty, they lose the ability to transfer heat effectively. Your cooling system then has to work harder, raising the refrigerant pressure higher. You may notice reduced cooling capacity and an increase your utility bill.

Pledge: We will clean the condenser coil fins to restore their efficacy.

Heat Pumps

Defrost Cycle Timing

The defrost timer regulates how often your heat pump stops heating the inside of the home in order to clear its outside parts of any ice that may be forming. Although defrost cycles are necessary for the heat pump to operate at peak condition and efficiency, if the timer triggers the defrost cycles too often or for too long, you will notice adverse effects: a reduction in the heating of your home and increased heating costs due to the inefficiency of the system. Over time, an improperly calibrated defrost timer can shorten the compressor’s life.

Pledge: We time the heat pump’s defrost cycles to make sure they conform to specifications.

Auxiliary Heat Strips

Under particularly cold conditions, the heat pump may struggle to raise the temperature to the level you have set in the thermostat. Auxiliary heat strips provide increased heating when the system requires a boost in capacity. Being a back-up contingency, the heat strips do not activate unless such acute conditions trigger them, but when they do come online you are thankful you have a second line of defense against the cold.

Pledge: We ensure that the auxiliary heat strips will activate when the system needs supplemental heating to keep you comfortable.

Reversing Valve

The direction of refrigerant flow in your heat pump determines whether your system puts out heating or cooling, according to how you’ve set the thermostat. The reversing valve functions as the master switch, in a sense, governing the direction of the flow and thus whether you will feel a change in temperature matching your expectations. If the reversing valve wears out, it can cause loss of heat – to the point of even further cooling an already cold room – and waste energy.

Pledge: We will verify that the reversing valve directs heat flow correctly and at peak efficiency.

Gas Heating Systems

Combustion Air Openings

Your gas heating system needs openings to the outside to bring in fresh air. Dedicated intakes and ducts channel the air in a controlled manner, providing the system what it needs while maintaining a tight seal on the house’s insulation and, in turn, promoting energy efficiency. Exposure to the exterior of the home does pose its own issues, however. Foreign objects like dust and dirt buildup as well as other potential obstructions such as even insect colonies, clog up the intakes and ducts and reduce airflow.

Pledge: Combustion air openings will be checked for blockages.

Flue Pipe

The function of the flue system is to vent the combustion gases that the furnace produces. When the air flow through the flue is restricted, pressure rises and the gaseous emissions from the furnace start to back up. The most dangerous product of the combustion in the furnace is carbon monoxide – which is odorless, colorless, smokeless, and potentially lethal. The build-up of gas also presents a fire hazard.

Although the flue pipe typically terminates outside with a vented cover, various sorts of detritus from leaves and twigs to bird and squirrel nests have been known to accumulate and block the flue.

Pledge: We inspect the flue pipe for unrestricted air flow.

Thermostat

When you input the desired temperature setting on your thermostat, you depend on the accuracy of its readings to determine when the gas heating system should initiate heating and raise the temperature to the mark you set. If the thermostat is improperly calibrated, the temperature it reads will not match the true state of your home’s environment, and the system will run longer than indicated. Every degree above 8 degrees of difference between your thermostat’s readings and the actual temperature will incur a 5% to 8% overrun to the cost of heating your home.

Pledge: We check the thermostat for accuracy and calibrate it if necessary.

Panels

Gas heating systems contain multiple panels, and not all of them may be visible on the outside or the front – some models nest subordinate panels within the compartment that the main access panel services, and some models compound further panels on the back or side of the unit body. All panels serve as a barrier to keep the internal components in and external factors out. Wherever they may be, loose panels present the dual drawbacks of loss in efficiency for the system and exposure to danger for your home’s occupants.

Pledge: We will inspect and secure all panels.

Carbon Monoxide Safety Check

The heat exchanger of your gas heating system is what keeps the combustion area separate from the heated air that circulates through your home. If a crack were to develop in the heat exchanger, carbon monoxide could escape into the air that you and your family end up breathing. Since carbon monoxide is a colorless, odorless, tasteless, poisonous gas and exposure to it can cause illness or even death, we take the integrity of the heat exchanger seriously and test it for leaks.

Pledge: We will check to make sure carbon monoxide levels are safe within the system.
