You want to know for sure if you need a heat pump repair in Rochester, MN. Before you call over a heat pump service provider, you should keep your eyes and ears open for all the possible warning signs that an ailing heat pump will give off. There will be, for example, a drop in performance. Heat pumps normally cycle two or three times an hour, and each cycle should last 10 to 15 minutes. Abnormally short or long cycles point to an issue — perhaps an oversized or undersized heat pump. You may have a bad compressor, or it may be something less serious, such as dirt buildup in the air handler. Perhaps the heat pump doesn’t blow out as cold as you like; this could signify a failing motor.
In addition, you may notice that the heat pump makes continual, loud noises while in operation. A professional would be able to diagnose them, but you should know in general that banging, grinding, hissing, and gurgling should never be heard. Anything from bad bearings to leaking refrigerant lines could be behind these.
