A heat pump is an alternative climate control system for your home over more traditional forced air heating that operates by using a heat exchanger to move heat from the exterior of your home to the interior, and vice versa, depending on the season. However, just like all other major appliances, heat pumps can begin to degrade over time and perform less effectively. Understanding some of the signs associated with a heat pump that has begun to fail can help you understand when you should contact an HVAC professional to have your unit inspected and replaced.
The easiest to notice sign that your heat pump may be malfunctioning is if there are strange and loud noises that come out of the unit while it is in operation. Keep in mind that the regular sound of the fan and heat exchanger operating should be relatively low, nothing more than a dull hum in the background. Therefore, banging, screeching, groaning and other types of noises can all point to a mechanical issue that is increasing the amount of wear and stress that your unit is experiencing, precipitating a unit failure. Having a professional inspect the unit can help determine if you need to repair an individual part or replace the entire unit.
Drafts and Uneven Temperature
Another common sign associated with a heat pump that is no longer functioning normally is if you notice that irregular temperature spots have begun to develop in rooms in your home that have previously been heated or cooled evenly. Drafts of hot or cold air, depending on the season, can point to a heat pump that is no longer able to effectively exchange heat with the exterior of your home. This will reduce your overall comfort levels throughout the year while also increasing your energy bills, since your heat pump will have to operate more often to provide the same temperature level.
Finally, if you find yourself constantly contacting an HVAC professional, such as from Bourke's Service Co, to come in and replace individual components within your heat pump, more than once a year, you may want to simply consider replacing the unit. If multiple parts need to be replaced within a unit, the entire unit is likely on its last legs. Further, replacing the unit instead of constantly changing out individual parts can actually be the sound financial decision, as a constant stream of repair bills can quickly outpace the cost of a replacement unit.
