Your heat pump is powerful, efficient, and convenient\u2026 when it works. It looks fine, it\u2019s still cooling your home (or heating it), but it\u2019s not switching to the other mode. Every time you try, it just refuses. There are a few things that could be wrong that we\u2019ve seen in all our time providing heat pump repair in Arlington, WA<\/a>. Here\u2019s what you need to know.<\/p>\n\n\n\n\n\n\n\n

First, Change Your Air Filter<\/h2>\n\n\n\n

At the end of the day, a heat pump is still a forced-air HVAC system. It needs a fresh intake of air, and a clean filter provides that while preventing debris from getting inside and mucking up the heat pump\u2019s internal components.<\/p>\n\n\n\n

But when that filter gets dirty, airflow is restricted, and it can\u2019t do its job properly. Your air filter should be changed out every 30-90 days depending on use. If you ask us, simply keeping a 30-day recurring reminder and switching your filter out at that point is best.<\/p>\n\n\n\n

If you\u2019re in disbelief at how much dust your filter captures, hold a brand-new filter up to your current one. It captures so much, but eventually, it becomes a hindrance instead of a helping hand to your heat pump.<\/p>\n\n\n\n

It\u2019s Likely a Solenoid Issue<\/h2>\n\n\n\n

The solenoid in your heat pump is there to physically cause the change when you switch from one mode to another. But a solenoid can be rather finicky, and sometimes they get jammed. These can either just be stuck, or they may break from time to time and need to be replaced. Thankfully, they\u2019re rather inexpensive parts and won\u2019t be the downfall of your heat pump.<\/p>\n\n\n\n

Maybe it\u2019s Your Thermostat<\/h2>\n\n\n\n

Your thermostat isn\u2019t just the controller for your heat pump\u2013it\u2019s the brains of the whole operation. Your heat pump doesn\u2019t inherently know the temperature, or when to turn off and on. That\u2019s the thermostat\u2019s job.<\/p>\n\n\n\n

It gauges the room temperature, then sends an \u201cON\u201d or an \u201cOFF\u201d signal to your heat pump. So if your thermostat isn\u2019t gauging the temperature properly, it can make it look like your heat pump is slacking. There are a few things you can do:<\/p>\n\n\n\n
