Maintenance saves!

We recommend that homeowners have a complete system check up performed by a qualified service technician at least once a year. A check up by one of our service technicians will include examining the coils for dirt and cleaning them as needed. Prolonged exposure to the elements will eventually lead to some built up of grime such as lawn cuttings, windblown dirt, jet fuel residue, smoke, pet hair, rust or even bacteria. An ignored maintenance schedule will lead to diminished performance and increase operational costs.

The result of environmental grime and dirt built up will be to lower energy efficiency, compromise performance, reduced cooling capacity and lead to a dramatically higher electric bill. Over time dirty coils will not only lead to evaporator coil freeze up but will inevitable progress towards premature compressor failure. To check to see if your coils are buildings up grime take a moment to take a look about every 3 to 4 months, if they are dirty call in a professional service technician to protect your investment.

Since the evaporator coils are contained outside the house, and with most equipment air flows across the outside of the coils and discharged out the top of the unit the grime will built up on the surface of the coils and be clearly visible. On average most homeowners only need to have their entire systems checked about once a year, but all environmental conditions are not always equal. Some neighborhoods especially those within the flight path of either a large, small municipal or executive airport may need more frequent inspections and cleaning.

Although visual inspection is a good indicator the clearly visible section of the coils may not appear to have developed a grimy build up. Other factors such as suction and discharge pressures may be better indication of dirty evaporator coils. Higher than normal pressures are an excellent indication that the coils within the unit need maintenance and cleaning, only a qualified service technician would be able to detect these subtle changes in the output of your unit.

Checking the evaporators on a split system is an entirely different beast. They are usually inside the house and can be tucked away in an attic, closet or crawl space. The coils themselves are hidden away in a blower cabinet and in older home possible a furnace or plenum. Homes with this type of environmental cooling system would be best served by a minimum yearly maintenance inspection.

Don’t sacrifice your comfort!

If your system has clear signs of diminished performance, such as lower setting needed to cool the home even though the outside air temperature is not above average or actual freezing of the evaporator coils themselves. Then your system needs a service inspection to prevent premature failure. An evaporator coil service from an experienced professional can save you thousands of dollar in repairs of the entire cost installing a new unit.
