Professional Air conditioning Maintenance

air conditioner maintenanceWhy is Air Conditioning Maintenance Important? - Air conditioners need yearly maintenance to maintain proper performance. With the proper maintenance your air conditioning and heating equipment will work more economically and be more dependable for years to come. With a few easy and routine procedures you can keep your unit at peak performance and get the maximum amount of comfort from your HVAC system. Air conditioners consume a large portion of the average monthly power bill and proper and efficient maintenance can make a significant difference. Your air conditioner loses 5% of its overall efficiency every year it goes without proper professional maintenance. Systems operating at peak efficiency can cut monthly energy costs by up to 25%. Proper maintenance effectively doubles the life span of the average residential heating and cooling system. Many of the health risks that are associated with poor air quality can be greatly reduced or eliminated with proper system installation and maintenance.

Recovering Lost Efficiency - Fortunately most users can recover lost efficiency through service and maintenance from a trained professional. With regular maintenance a air conditioning unit will keep up to 96 percent of it's original efficiency. Also a unit working at its full capacity will keep your home more comfortable by controlling humidity and maximizing the cooling available.

A yearly inspection of your air conditioning or heat pump system should include the following 24 important items.

professional air conditioning maintenance1) Refrigerant charge - It is extremely important that the coolant or Refrigerant level of an air conditioning system be tested frequently. A 10% loss of Refrigerant or coolant will cost the home or business owner 20 percent more in electrical costs and can cause undue wear and tear on your unit. The Air Conditioning Contractors of America or ACCA recommend Testing once a year to maintain the proper Refrigerant levels. If your residential air conditioning unit needs Refrigerant a properly licensed and trained contractor can usually make a repair and add it on the spot. Refrigerant is a chlorofluorocarbon or CFC and will damage the Earths ozone layer if it is released into the atmosphere. The laws on CFC's do not allow an air conditioning contractor to add Refrigerant to a leaky commercial system if the leak is within 30% of the units capacity. They are required to fix the leak in the system o to shut the system down. Violation of this law may cause contractors to loose their license.
