Maintenance boosts green HVAC, saves money
With warmer weather now arriving in much of the country, spring is the ideal time to perform coil cleaning and maintenance, an HVAC market cleaning company says.
Cleaning coils before the summer is smart for homeowners and small businesses because it can help ensure that HVAC construction systems perform properly throughout the season and without consuming excessive amounts of energy.
“Coil cleanings save homeowners money through increased energy efficiency,” said Michael Hardy, managing director of SpeedClean. “With the right products, contracting professionals can take care of condenser and mini-split coil cleanings fast, saving themselves money.”
When coils are not cleaned regularly, particles build up in between, which makes the air handler work harder and the heat-exchange process less efficient. HVAC construction industry organizations such as the Air Conditioning Contractors of America and the American Society of Heating, Refrigeration and Air-Conditioning Engineers agree that preventative and green HVAC maintenance practices, such as regular coil cleanings, are key to keep equipment running at their peak efficiency, save energy and decrease the likelihood of system failures, potentially extending the life of the HVAC market system.
Dirty coils also negatively impact indoor air quality. When dirt, dust and pollen are clogging the coils, more of these particles are let out into the home or office along with the cooled air. Unclean coils also promote the growth of bacteria, mold spores and other unhealthy organisms that can produce bad odors, allergies and generally contaminate the air.
What steps should contractors take to clean condenser and air-handler coils?
SpeedClean’s coil cleaning checklistwill help ensure HVAC construction technicians and sheet metal works contractors have taken all the necessary steps to properly clean a home or office’s condenser or air handler coils. Some items on the list include:
Inspect and clean mini split ductless systems at least annually.For greater efficiency, check mini split systems between seasons – once in the fall and once in the spring. Inspections should include checking filters, coils and blower wheels for dirt buildup.
Avoid cleaning coils using compressed air or nitrogen.This blows dirt and debris into the air, creating IAQ problems and possibly re-contaminating the coil and blower wheels that were just cleared. It also displaces any mold spores, which can create health problems and further mold issues if not properly managed.
Use pressurized water.This is the best way to flush dirt and debris and thoroughly clean the coils, using limited chemicals. Consider using a portable, battery operated coil cleaning system like the CoilJet CJ-125 for cleaning coils and blower wheels.
Protect walls and floors during the coil cleaning.Condensate lines generally don’t do a good job of moving a lot of water. Using a bib system, such as the Mini Split Bib® Kit, will safely capture excess water and cleaner and protect walls, floors and furniture from overspray.
Treat coils to prevent the smelly “dirty sock syndrome.”Apply an Environmental Protection Agency-registered mold and mildew inhibitor to protect against odor-causing bacteria for months at a time. Make sure the chemical is safe to apply while the space is occupied, like Mold Control from BBJ.
Don’t forget about the condenser coils.Dirty condenser coils can drive up the ductless system’s heating and cooling costs. Make sure to clean condenser coils with pressurized water every time indoor coils are cleaned.
