Heat pump repair is one of the more common calls we get in August, and honestly, it makes sense. In the summer, your heat pump essentially works like an air conditioner, pulling heat from inside your home and releasing it outdoors. During Michigan’s hottest stretches, that can mean longer run times and added strain on the system. Before you assume the worst, though, there are a few things worth checking on your own. Some issues have simple explanations, and catching them early can save you time, money, and a very sweaty afternoon.
Start With the Basics: Airflow and Filters
A dirty air filter is behind more heat pump problems than most people realize. When airflow gets restricted, the system has to work much harder to move air through your home, which can cause it to overheat, short-cycle, or just stop cooling effectively. Check your filter first. If it looks gray and clogged, swap it out for a fresh one and give the system a few minutes to recover before you decide something bigger is wrong.
While you’re at it, walk around and make sure your vents inside the house are open and not blocked by furniture or rugs. It sounds small, but blocked supply and return vents can throw off the whole system. We see this fairly often with customers in Portland, DeWitt, and the surrounding communities, especially in older homes where furniture layouts have shifted over the years.
Check the Outdoor Unit
Your heat pump’s outdoor unit needs room to breathe. If grass, weeds, or shrubs have grown up around it over the summer, that can seriously limit how well it can release heat. Clear away any vegetation within about two feet of the unit. You can also gently rinse the coil fins with a garden hose (not a pressure washer) to remove dust and debris that builds up over the season.
Also take a look at whether the unit is running at all when you call for cooling. If the outdoor unit is silent while the air handler inside is running, that points to a different problem, possibly an electrical issue, a refrigerant concern, or a failed component that really does need a technician.
Look at Your Thermostat Settings
It’s worth a quick glance at the thermostat before you call anyone. Make sure it’s set to “cool” and not “heat” or “emergency heat.” If someone in the house bumped a setting or if the thermostat lost power briefly, it can end up in a mode that makes everything feel off. Also check that the fan setting is on “auto” rather than “on.” Running the fan continuously without the compressor cycling can make it feel like the system isn’t cooling, even when it’s actually fine.
When Something Still Seems Off
If you’ve gone through all of the above and your heat pump is still struggling, that’s when it’s time to call in a professional. Some issues, like low refrigerant, a failing capacitor, or compressor trouble, aren’t things you can or should try to address yourself. Heat pumps are complex systems, and a misstep can turn a moderate repair into a much bigger one.
