Four of the most common heat pump problems and how to fix them fast
We get how frustrating it is when you run into heat pump problems. Imagine it’s a dreary day and a bitter wind whips around your face. You can’t wait to get into your nice warm home, at the thought of it your pace quickens, you throw open the front door pick up your heat pump remote, hit the power button, and…..nothing. Don’t worry we’ve got the answers to the four most common heat pump problems sorted here. Find out what’s going on with your heat pump and how to fix it.

It just stops and won’t turn on!
What to do when your heat pump just doesn’t work or won’t turn on. It is extremely frustrating when you’re looking forward to returning to a warm home only to find that your heat pump won’t even turn on.
It can be a common problem, that also has some easy solutions. This can be caused by something as simple as the batteries in your remote – try changing the batteries in your remote (usually 2x aa) and see if that solves the problem. Otherwise, check that your heat pump is receiving power. Check the mains power in your house is still on and the switch hasn’t flicked off (or tripped). Check for any loose wires or blockages that may be causing the issue – if you see any of these you may need to call in a heat pump expert.

Is your heat pump trying to talk?
Making weird rattles, bangs, and just generally strange sounds?
This can be an annoying heat pump problem – don’t fret until you try some of our solutions.
The most common causes of your heat pump making weird noises are that the vents are shut or there are loose parts. Check your heat pump over to make sure nothing on the exterior has come loose, such as a screw. Make sure the air vents are open and test it again. Check your outdoor unit as well, and make sure there are no leaves or grass near the vents. If your heat pump still doesn’t sound right after you have checked for blockages or loose items – then you should call your heat pump expert to investigate further.
It doesn’t respond to the remote
Just like any other technology heat pumps can sometimes run gave a few problems too, but these are usually a super easy fix!
What to do when your heat pump won’t respond? Often, having a little patience can help.
It’s not recommended to press lots of buttons on the heat pump remote all at once, especially on start-up, as it can take a heat pump a little time to wake up (just like we do in the morning). If that’s not the problem, check the batteries in the remote – doing this majority of the time resolves the issue. We’d recommend changing your batteries at least once a year to avoid this.
No heat at all
Sometimes you can switch your heat pump on and sure it’s blowing air but not enough! This usually happens because the filters need cleaning or the air ducts are blocked.
The way a heat pump works is the outside unit draws in the air around it. It takes the heat energy from the outside air which in turn heats up the refrigerant gas inside.
The heated gas is transferred through the pipework to the heat pump, which draws the air from within the house over its coil then it heats the cold air.
What can happen is the indoor heat pump filters can get blocked which limits airflow over the coils. This in turn restricts the amount of heated airflow from the heat pump.
The first step is to check the outdoor unit.
Make sure nothing is blocking or covering the outdoor unit.
Check your filters and ensure they are clean and free of dirt and other loose material. If they are dirty – that’s good news because your air filtration system is working on keeping your air clean.
But, it also means you need to clean them to allow sufficient airflow through the filters.
Make sure you keep on top of regular maintenance and keep the filters cleaned to help avoid this problem altogether.
To ensure your heat pump is running efficiently try these solutions. We do recommend having your heat pump system cleaned and checked by a professional at least once a year.

Mitsubishi heat pump issues
Hi, I was wondering if I could get some advice on a recently installed Mitsubishi Hyper Heat mini split system. The heat pump is not functioning properly and despite multiple visits our HVAC contractor (a Mitsubishi diamond contractor no less) has not been able to fix the issue — their level of expertise on these units seems very subpar. I’ll try to give as much detail as possible. I did hours and hours of research prior to purchase but am not an HVAC tech so please don’t jump on me if I don’t have terms right.
The system is a 2-ton MXZ outdoor unit with 3 indoor units (two 6K btus in bedrooms, one 12K in living). The units don’t maintain heat, sometimes fail to put out any heat, and go through cycles where they enter defrost mode every 20 minutes with no frost on the outdoor coil or change in outdoor temp. A typical day will be, say 23 degrees outside and the unit defrosts over and over, only blowing cool or lukewarm air in between defrost cycles (which last about 15-20 minutes), so the indoor temp drops as low as 52. The unit will then inexplicably run with fan on high giving off good heat for an hour (or 2, or 3, no pattern) raising the temp to near setpoint (70) then enter the hellish defrost cycle loop for another few hours, or a full day. again, there is no pattern, no big change in wind or snow or huge temperature drops outside. This can occur in the morning, afternoon, middle of the night, etc. The unit can, on some days, keep the house warm when it’s 5 and snowing outside and struggle when it’s 30 and sunny. or vice versa.
Our contractor has added refrigerant after the second visit (system was 2 pounds low), replaced thermistor outside, replaced a board in the outside unit, etc. on third visit. There are no error lights/codes. They also had Mitsubishi rep on the phone for two hours, running different tests and even Mitsubishi had no answers on fourth visit. We’ve tried all the simple stuff (using a higher setpoint temp, adjusting vanes, running both with and without the iSee sensors active, different fan speeds, etc.).
The home is a two story 1,300 sq. ft. 1910s farmhouse on the Iowa/Minnesota border but with vinyl windows, blown-in attic insulation, blown-in wall insulation, and closed cell foam encapsulated foundation/basement so reasonably tightly wrapped. If the unit were undersized or the house was leaky, wouldn’t the unit just blow heat all the time and never reach temperature? Also, a small 1,500 watt Vornado can heat the entire main floor living space to 64 on a 10 degree day, so I know the house can be kept warm. We have no dedicated backup heat source (just some larger space heaters) because from what we were told and the research I did, these units should still put out top level heat down to 4 degrees, and partial heat down to -13. We figured we could supplement on very cold days but having to run backup heat with a top-of-the-line heat pump when it’s 20-30 degrees out is absurd. I could have installed more reliable (albeit inefficient) hydronic baseboards for thousands and thousands less.
This has to be an issue that someone with a decent working knowledge of these systems can diagnose. Our contractor up here seems to be out of their league, which is frustrating given the fact that they’re supposed to be a certified Mitsu diamond dealer with great reviews. We’re at our wit’s end. is this normal for these systems (meaning their marketing is absolute BS) or do we have a right to be mad that this contractor can’t pinpoint the issue? And what do we try next?
