Why do you need preventative maintenance?

• 1/100th of an inch of dirt on an evaporator coil can increase operating costs by 5%
• A dirty blower wheel can reduce air flow by over 30% which causes the unit to run longer
• A 23% refrigerant undercharge can cause the unit to operate less efficiently by up to 52%
• Improper refrigerant undercharge will cause premature compressor failure
• A small air leak in your return air ducts within a 120 degree attic can double operating costs
• A 10% under charged system will reduce efficiency by 25%
• The bottom line is: Preventive Maintenance saves you money!
