Maintenance

So what services should be performed for residential systems?

Here are some of the standard services that we recommend:

check-icon-greenCheck and update coolant levels. Coolant levels that are too high or too low can affect the efficiency of the system. A reduction in coolant levels of 10 percent can potentially increase operating costs by as much as 20 percent!
check-icon-greenReplace or clean dirty air filters. Dirty air filters are the primary cause of outages that require on site repairs. Dirty air filters can cause the units to work harder and will affect the quality of the air the system produces.
check-icon-greenClean, balance and calibrate the thermostats. Electricity consumption decreases by 8 percent for each degree a thermostat is lowered. Additionally, dirt in the housing can affect temperature readings. A thermostat that has been bumped and loses its level can also affect the accuracy of the temperature calibration.
check-icon-greenInspect and clean condenser and evaporator coils. Dirty coils reduce energy efficiency and make the compressor run longer than is needed.
check-icon-greenInspect wiring and connections. Damaged or old wiring can be a fire hazard. Improper connections can affect voltage and flow of current which can actually damage your system.
check-icon-greenCheck that the unit cycles on and off properly. The systems should come on, run through a full cycle and then shut off properly. If not, they units may be wasting energy and not providing the level of comfort you expect from your systems.
check-icon-greenClean out the compressor housing. Leaves, dirt and other debris can get trapped in the housing and affect the air flow around the unit. If the compressor is exposed to full sunlight, planting shrubs nearby or installing barriers around the unit can provide needed shade and reduce the temperature of the unit itself.
check-icon-greenCheck and clean drains and tubing. Tubes can become clogged and water can back up and damage not only the unit but nearby structural areas of the building. Drains and tubing should be checked to make sure they are all properly moving water outside of the building.
check-icon-greenLubricate all moving parts. Air conditioning units can become sluggish if the fans and motors that make a unit work are not properly oiled.
check-icon-greenCheck the area around the unit. Make sure the area around the unit has been cleared and no vegetation has been allowed to grow too close to the compressor. Restricted airflow around the unit can reduce efficiency by up to 15 percent.
