INFORMATION FOR HEAT PUMP CUSTOMERS
In many cases a homeowner does not know what to expect from their new heat pump system. The information listed below should be helpful.
- During the cooling season, the heat pump operates like a conventional air conditioning system.
- During the heating season, the heat pump rarely delivers hot (135°F) air, but delivers large quantities of warm (90°F) air. The unit will probably run almost continuously in cool weather. It was designed to do so.
- The outdoor unit will “change tune” slightly as it moves from cooling to heating as the temperature varies, or as frost builds up on the outside coil.
- There will be moisture draining from the surface of the outdoor coil when the unit is in the heating cycle. This moisture will turn to frost when the outdoor temperature fall bellows 40°F.
- The outdoor coil may become totally white with frost during cold weather. Unless this condition persists for over 1½ hours without defrosting, the customer should not be disturbed. Frost will build up most rapidly during damp, cool weather (28°F to 38°F).
- When the heat pump defrosts, it will, without stopping, give a slight “swoosh”, stop the outdoor fan, and briefly deliver cooler air inside. The duration of its defrost cycle will vary from 30 seconds to 10 minutes, according to the amount of frost on the outdoor coil
- Steam or fog from the outdoor unit is normal during defrost.
- During cold weather (usually below 35°F), the auxiliary heat light on the thermostat may come on and off as the 2nd stage heat is activated. This light may also come on during defrost. This is normal.
- The emergency heat switch on the thermostat is to be used when there is a problem with the outdoor unit. This switch only shuts down the outdoor unit and runs the system on 2nd stage (auxiliary) heat.
- It is extremely important that nothing restricts airflow or the defrost water runoff near the outdoor coil. Leaves, grass clippings and the like should be cleaned off the outdoor coil. In snow country, drifting snow should be cleaned from around the unit.
- Return air filters must be cleaned or replaced monthly. Dirty filters restrict airflow and increase operating costs.
- Indoor air supply diffusers must not be blocked or restricted by furniture or draperies.
- Night setback during the system’s heating mode is not recommended, unless you have an intelligent recovery thermostat. The heat pump seldom has the capacity to raise space temperature quickly. Heating setback (maximum 10°F) will provide some economy if the space is to be left unoccupied for two or more days.
- It is recommended that the system have a professional service and maintenance check once or twice a year. After your warranty expires, this service is provided by us, on a routine basis, via a Service-Maintenance Agreement.
