Frequently Asked Questions

How do you properly set a thermostat?

Set your thermostat switch to either the “heat” or “cool” position. Set the blower switch in either the “on” or “auto” position. If the blower is switched to the “auto” position, the fan will cycle on and off automatically when the thermostat calls for heating or cooling. If the “on” position is selected, the indoor fan will circulate air through your duct system and remains on. UNDER HIGH HUMIDITY CONDITIONS THE “AUTO” POSITION SHOULD BE USED.

Set the thermostat control indicator to the temperature you prefer.

Most people find 75 to 78 degrees an ideal comfort level in cooling and 68 to 73 in heating mode.

Does setting the thermostat to a lower position make the unit cool faster?

No, to achieve a more even temperature and humidity control, keep your thermostat set allowing the unit to operate automatically for you.

On a very cold, moist day does your heat pump automatically go into a defrost mode?

Yes. This mode melts off any ice that may have formed on the outdoor coil. As a defrost cycle is initiated, the reversing valve switches, inducing heat to the outdoor coil. You may hear a switching sound when this occurs. During this period of time DO NOT TURN THE SYSTEM OFF, AS THIS IS A NORMAL FUNCTION OF THE HEAT PUMP. After the ice has melted off of the outdoor coil, the heat pump will automatically return to the normal heating mode.

How do we achieve comfort without spending a fortune on the electric bill?

Avoid frequent thermostat resetting. Set it at the desired temperature and leave it there.

Don’t set your thermostat too low. As a general rule, a thermostat setting of 75 to 78 degrees will provide comfortable room temperature and will give the best economy.

When entertaining a large group, lower the thermostat 2 to 4 degrees a few hours before your guests arrive.

Don’t turn off the system just because you’ll be away for the day or more. Heat and moisture will build up in the house. It takes quite a while to restore comfort, but it costs relatively little to maintain it.

Keeping windows and doors closed will not only keep out hot, humid, outside air, it will also keep out dust, dirt and street noise.

Don’t open windows after dark. Night air may seem cool but it is also moisture-laden. This increases the work your system must do the next day.

Use filters. CHANGE YOUR FILTER EVERY MONTH.

Keep the sun from adding unnecessary heat to your home by shading the exposed windows. Draw shades and drapery on the east windows in the morning and on the west windows in the afternoon. The less heat and moisture there is to overcome, the lower your operating costs become.

During the peak summer afternoon hours will the unit run most of the time?

Yes. Your heating and air conditioning system has been designed and sized for your particular home. As temperatures rise outdoors, expect your air conditioner to run for longer periods of time. This is normal operation.

How will I know if my unit needs service?

Before you call for service, please check the following list of conditions and follow suggestions to prevent costly charges for a service call, which are not due to a malfunction of your equipment. If you don’t see your answer here, then phone our service department at 252-636-5841.

Be sure that the main electric power to the equipment is turned on. Check breakers in your electrical panel box to make sure they are in the “ON” position.

Make sure that the thermostat is set to the desired temperature and in the proper positions.

Make sure your filter is clean and not blocking any airflow.

IMPORTANT: DO NOT TURN YOUR UNIT TO THE “OFF”, “COOL”, OR “HEAT” POSITIONS IN RAPID SUCCESSION, AS THIS WILL TRIP THE SAFETY ON THE COMPRESSOR AND IT MUST BE MANUALLY RESET ON SOME MODELS.

IMPORTANT: DO NOT OPERATE THE AIR HANDLER, FURNACE OR AIR CONDITIONER WITH THE BLOWER DOOR REMOVED OR THE FILTER ACCESS DOOR OFF.

What if my living area is not cool or warm enough?

Check controls and make sure they are set at your desired temperature.

Check filters and replace if dirty.

Make sure shrubbery or other objects are at least a foot away from the outside condensing unit, allowing the unit to have proper exhaust.

Doors and windows are open or are opened too frequently.

Temperature dial is being changed too often. Allow sufficient time for the unit to reach capacity. Do not constantly change thermostat temperature setting. It is best to find your comfort level and leave it.

When cooking or drying clothing use your exhaust fan if available.

How can I keep my unit as good as new?

Proper care and service will keep your system operating like new for many years. Lack of care may damage the unit and cause you unnecessary expense.

Much effort has been put into installing your system and the choice of quality materials. By taking proper care of your investment, it should give you many years of energy-efficient performance.

How often should I replace the filter?

Replace the throwaway filter once a month. That’s the most important thing you as a homeowner can do. A dirty and clogged filter reduces the efficiency of your system, causes erratic performance of controls and can result in damage to the motor or compressor. Inspect the filter at least once a month when the system is in constant operation.
