With the proper maintenance and care, your equipment will operate economically and dependably. There are a few simple, routine maintenance operations you can do to help ensure the best performance and comfort from your system. We recommend that you have your local HVAC contractor perform these tasks in their entirety.

Make sure of your Safety

• Disconnect all electrical power to the unit before removing access panels to perform maintenance. Please note that there may be more than one power connection switch.
• Although most manufacturers takes special care to prevent sharp edges in the construction our equipment, it's best to be very careful when you handle parts or reach into units.

Check the air filter in your furnace or fan coil every 6 to 8 weeks. A dirty filter will cause excessive strain on your furnace, air conditioner or heat pump. Replace your filter when necessary, or clean it if you have the reusable type. (If you have a reusable filter, make sure it's completely dry before you re-install it.) The prefilter and collection cells of an electronic air cleaner should be cleaned at least two or three times per year.

Keep your outdoor condensing unit free of debris . If you keep grass clippings, leaves, shrubbery and debris away from your outdoor unit, it should only require minimal care to operate properly. Check the base pan (under the unit) occasionally and remove debris, to help the unit drain correctly.

If the outdoor becomes dirty, use a brush or a vacuum cleaner with a soft brush attachment to clean the surface. To clean dirt that is deep in the coil, contact your AC dealer.

Inspect your furnace's combustion area and vent system before each heating season . If you find dirt, soot or rust, your system may not operate properly or at its peak efficiency. Call your servicing dealer and do not operate your furnace until it is professionally inspected and/or repaired.

Take special care of outdoor condensing units in ocean environments. If your unit is located near a seacoast, you can help preserve its optimal condition with a little extra care. Ocean mist and sea breezes carry salt, which is corrosive to most metals.  (Ask your installing contractor about the appropriate interval in your area.)

Make sure your outdoor unit stays in a level position . If the support for your split-system outdoor unit shifts or settles and the unit is no longer level, re-level it promptly to make sure moisture drains properly out of the unit. If you notice that water or ice collects beneath the unit, arrange for it to be drained away from the equipment.
