Why does my mini split fan freeze?
Unfortunately, if it gets too cold, the water in the drain pan may freeze before it leaves the pan. The ice can get too thick, and this may lead to the fan blades freezing to the drain pan. Another issue that may happen is that moisture may get lodged between the coil fins. When this moisture turns into ice, the coil may crack. The damage can be costly to repair. Therefore, it is best to install a drain pan heater to prevent damages to your mini-split during frigid weather.
How cold should a mini split heater be?
Since the heat pump of your mini split ductless heater system is not capable of heating up a cold house rapidly, learn to compensate for this fact. At times when the house in not occupied, like during weekdays when all members of your household are at work or school, turn the indoor temperature down to around 60 degrees F or lower. You can also keep the temperature at around 60 degrees at night, when everyone is sleeping. During longer times when no one is home, such as during family vacations and on holiday weekends, you may want to lower the temperature of your home’s interior to 50 degrees F. Even at this lower temperature setting, the unit will continue to circulate the air, maintaining a good uniform level of warmth throughout to prevent isolated cold spots from forming.
Why use a drain pan heater for mini split?
This frozen moisture may also lodge between the coil fins and crack the coil. Because repairing this type of damage can be costly, it is best to use a drain pan heater to prevent ice buildup and damage to your mini split condenser coil during extremely cold weather.
Why does my mini split freeze?
During cold weather when you operate your mini split for heating your home’s interior, frost will often accumulate on the outdoor condenser coil. By turning the condenser controls to the defrost setting, you can cause the frost to melt. The resulting moisture will drip into the unit’s drain pan. Although this will remove the frost from the coil, it can lead to another problem, since the dripping water may freeze before it leaves the drain pan. If the resulting ice gets too thick, it may freeze the fan blades to the pan.
How to keep mini splits warm?
If possible, mount the condenser under an overhang on an outer wall of your home. This overhang will serve as a roof over the condenser to protect it from any buildup of snow and ice on top of it. Be sure, however, to leave adequate space between the overhanging “roof” and the top of your condenser to ensure its good operation. The condenser unit should be mounted high enough above the ground so be well above the height of any accumulated snow, including snowdrifts following windy weather conditions.
How high should a mini split be mounted?
The energy-efficient, indoor ductless heating unit of your mini split system will operate at optimal capacity for quality heating and total home comfort if you mount it approximately 18 inches above the floor. The flow of heated air from the unit should not be obstructed by the placement of furniture or other objects directly in front of it. When you mount the unit at a low position, the heated air first circulates throughout the room at floor level and then moves upward, heating the space thoroughly. Anyone sitting in the warming room will not feel overheated since the flow of heating air is entering the room at floor level. Also, when your indoor unit is installed at a low position, cleaning the unit filter is quite easy.

Can you use warm water to melt snow?
You’re risking major (and expensive to repair) damage. If you aren’t able to easily brush away the snow and ice, clear away as much as you can and then use warm water to melt what remains. The heat pump itself will also work with you to melt away ice or snow that is affecting its performance.
What happens if you have ice and snow on your heat pump?
In the winter, you run the risk of clogging the unit with ice and snow. During every month, debris and storm damage can take its toll. When you have ice and snow blocking the airflow between you heat pump and the outdoor air, you reduce the energy efficiency of your system and may even damage the unit beyond repair.
How long does it take for a heat pump to defrost?
This cycle normally lasts around 15 minutes and works by returning the hot refrigerant back to the outdoor heat pump to melt the ice and snow (similar to how heat pumps work in the summer). You may notice some cool air coming out of your vents while the unit is going through its defrost cycle. This is normal. Just wait 10-15 minutes for the unit to kick back on.
What happens if your heat pump doesn't work?
If the heat pump does not come back on after its defrost cycle, you will continue to use “ emergency heat ” or “ auxiliary heat .” If your heat pump isn’t working, emergency heat may get you through the night comfortably , but you’ll want to call a professional technician to fix the root cause ASAP. If you ignore the problem and continue to use emergency heat, be prepare to pay sky-high electrical bills.
What to do if your heat pump isn't working?
If your heat pump isn’t working, emergency heat may get you through the night comfortably, but you’ll want to call a professional technician to fix the root cause ASAP. If you ignore the problem and continue to use emergency heat, be prepare to pay sky-high electrical bills.
How to prevent snow buildup on heat pump?
Here are some things you can do to prevent heat pump snow and ice buildup: Clear away debris from the unit (maintain a 2-foot clearance around entire unit). Turn the unit off (or “emergency heat”) when you are cleaning around it and be careful not to do any damage. Never use any sharp objects to remove snow and ice.
How to check if condenser is working?
Visually check your condenser, make sure it is clear of snow and undamaged (if the condensing fan motor does not have the proper airflow, there is a problem).
How to melt ice?
To melt ice, use a hose or warm water. Don’t use boiling water and don’t melt ice when the outside temperature is below freezing.
Why do you need to raise a condenser above the snow line?
The condenser needs clearance beneath it, because the melt from the defrost cycle is going to freeze once it drips down off the condenser, and in the worst case it freezes under the condenser and crushes the lowest row of the coil and the unit is ruined. So it makes sense to raise the condenser above the snow line and keep it under an overhang or roof.
How does a mini split heat pump work?
Recall how an air-source heat pump works: the outdoor unit has a compressor and a fan that blows air across a coil with refrigerant. In heating mode, the coil is colder than the outdoor air. As air is drawn through the coil, it gives up heat to the coil and leaves the other side colder. The more humid the air (and remember: the warmer the air is, the more moisture it can hold), the more condensation occurring on the coil. At temperatures at or below freezing, that condensation may freeze on the coil, reducing air flow through the coil and heat transfer to the refrigerant.
What is a defrost cycle?
Defrost cycles prevent freeze-ups. Heat pumps are designed to sense this type of condition, and periodically operate a defrost cycle, in which the heat pump reverses and uses some energy to melt the frost off the coils. Below is a photo of a Fujitsu condenser with frost building up:
What happens when a blizzard starts?
Once the storm starts up, outdoor temperatures are right around freezing, and the fine snow is being whipsawed around by the strong winds, which can drive the snow into the coil, coating it and triggering the defrost cycle. The blizzard becomes a moisture delivery system.
How many watts does a heat pump use during a blizzard?
And the duration rises to 15 minutes or so, with a power draw of 500 watts. Note also that after the defrost cycle the heat pump power draw jumps up to 900 watts or so, whereas before the storm it was running at 450 watts for much of the time.
How to tell if a heat pump is defrosting?
It appears that the firmware drives the heat pump up to the higher power draw for a certain amount of time after every defrost cycle, and when the cycles are frequent, it never drops down to the “cruising” power draw. So both efficiency and capacity are reduced, because the energy going into defrost isn’t going into the house. You can tell when the defrost cycle occurs because the indoor fan shuts off — otherwise it would be blowing cold air.
Why does my coil freeze?
As air is drawn through the coil , it gives up heat to the coil and leaves the other side colder. The more humid the air (and remember: the warmer the air is, the more moisture it can hold), the more condensation occurring on the coil. At temperatures at or below freezing, that condensation may freeze on the coil, ...
