Many people purchase heat pumps because they are energy efficient. During hot summer days, these energy efficient units may require a little extra maintenance.
- Leave the unit running. Heat pumps may takes upwards of 8 hours per day to keep the house at a comfortable level during the hot summer days. Even if you plan to be away from home all day, it is more energy efficient to leave the unit running, so that it can keep the temperature at a constant level.
- Don't be tempted to open windows to take advantage of cooler night air. Due to its nature, a heat pump must remove moisture from the air. While it might be tempting to turn the unit off and open the windows, during the cooler night air, this will allow the extra moisture that accompanies that cooler night air into the house. The heat pump will then have additional work to remove the moisture from the air. During the hottest summer days, it is likely more economical to leave the windows closed at night and leave the unit running.
- Keep an eye on filters. Air filters should be replaced at least once a month, or anytime they are dirty. Filters that are dirty or clogged will reduce the efficiency of the unit and may even cause more serious problems.
- Check indoor vents and ductwork. If furniture or curtains are blocking vents, this can create more work for the heat pump. Also check the ductwork for blockages, if you are able. Otherwise, it might be helpful to have a professional technician check for you.
- Monitor outdoor blockages. In the summer, activities like mowing the lawn may impact the efficiency of your heat pump. If grass clippings or leaves clog the outside unit, the heat pump may not work as intended. Try gently vacuuming to remove the blockage. If you are unsuccessful, you may want to invite the help of a professional to remove the problem.
- Schedule professional visits for regular maintenance. Regular maintenance visits will allow professional technicians to inspect your system and find issues before they turn into major problems.
Heat pumps can be a very energy efficient method of heating and cooling your home. Just be sure to properly maintain the system during the hottest summer days.
