Before you perform any kind of maintenance, consider these important safety precautions…
1. 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.
2. Although manufactures take special care to prevent sharp edges in the construction of their equipment, it’s best to be very careful when you handle parts or reach into units.
Routine Maintenance Tips:
- Check the air filter in your furnace or fan coil every 3 to 4 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 pre-filter and collection cells of an electronic air cleaner should be cleaned at least two or three times per year.
- Clean dust off of your indoor coil. With a vacuum cleaner and soft-brush attachment, you can remove any dust from the top and underside of the coil. Make sure you only do this when the coil is dry. If you can’t get the coil clean this way, call us for service.
- 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 coil 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 us for service.
- 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. 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 us, and do not operate your furnace until it is professionally inspected and/or repaired.
- Clean your humidifier at the beginning of every heating season. Review your owner’s manual for the proper procedure to clean the external and internal components of your unit. The evaporator pad should also be replaced before each heating season. If the water in your area is hard or has high mineral content, you may need to clean or service your humidifier more frequently.

Preventative Maintenance
Laconia Refrigeration/New England Mechanical stresses the importance of preventative maintenance programs for a variety of reasons, including:
- Extended equipment life including compressors
- Reduced Operating Costs
- Customers Realize a Substantial Savings by Preventing a Major Breakdown
- Increased Equipment Efficiency and Productivity
- Reduced Refrigerant Loss
- Reduced Potential for Hazards Related to Refrigerant Leakage
Calibration, cleaning filters and improved air flow all reduce the power need, as well as the wear and tear on motors and components.
The PM inspection also draws attention to leaking gaskets and seals, which are related to cooling or heat loss and any failing parts. These may need to be repaired or replaced in the future; we will let you know how to plan and partner with us.
