Don’t let your HVAC system deteriorate like the NYC subways

Neglected maintenance is one of the reasons given for New York City’s troubled subway system. Don’t let your heating, ventilation and air conditioning go off the tracks and leave you stranded.

Regular maintenance helps an HVAC system function at peak efficiency, just as an automobile does better with periodic oil changes and inspections. In the long run, you save money by extending the life of your system and minimizing trouble spots.

Light House provides maintenance inspections that keep your HVAC system running smoothly, and our trained technicians know how to prevent small problems from growing into big, expensive breakdowns.

What an inspection does
• Remove any dirt or debris that may have worked its way into the system.
• Change the blower filter.
• Clean and straighten the fins.
• Clean the evaporator coil, measure air flow and check the evaporator drain for algae and other potential clogs.
• Inspect tubes for holes or damage.
• Look for water dripping, a sign of trouble in the system, and check the drain flow.
• Make sure the unit is level and test the condenser to make sure it is running well.
• Check level of of refrigerant, look for leaks and capture any refrigerant that must be removed from the system.
• Look for leaky ducts and seal any that are found.
• Lubricate motors and check belts.
• Clean, tighten and coat electric terminals if needed.
• Make sure the thermostat is accurate.

The benefits
These steps improve the quality of your indoor air, significantly enhance the system’s efficiency and uncover mold growth, holes, kinked lines or other weaknesses in equipment. You may be pleasantly surprised to feel the system working better before the technician even leaves your home.

In addition, maintenance helps increase your system’s longevity, so a periodic inspection is a smart investment, especially considering the cost of a replacement system.

Help yourself
You can take a simple step to make your system function better: Change the air conditioner filter periodically during warm weather. This alone will lower your unit’s energy consumption by 5 to 15 percent, a government agency estimates.

“The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters,” says the U.S. Department of Energy. “Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5 percent to 15 percent.”
