Problems With Broken Ductless Heating Units

ductless-mini-splitUsing a ductless mini split heat pump for your winter warmth is one of the best methods available—especially in Florida, where the energy efficiency of a heat pump is an ideal match for our mild winters. Ductless systems take away the hassles of ducts and allow more flexible comfort options for both older homes and new home construction. Without ducts, an HVAC system will need fewer repairs. Ducts can be the source of several heating and AC problems, and with a ductless mini split, they simply vanish.

But not all problems leading to heating repair in Clearwater, FL vanish along with the ducts. During the winter, you may encounter broken ductless heating units. We’re going to take a look into some of these problems, how they happen, and what can be done about them.

A wall-mounted blower unit that won’t turn on

The most common trouble you might encounter with a ductless mini split heat pump is when one of the wall units in a room fails to turn on. The standard number of units for a ductless mini split is from four to eight per outdoor unit, so when one won’t work it doesn’t mean you have a house-wide emergency. You’ll still want the broken unit fixed. The first thing to check is to see if you need to change the batteries in the remote. If the remote is fine, there’s probably an electrical issue with the unit or a broken motor. Have an experienced technician examine it to see what needs to be fixed.

The blower unit is leaking

You see what looks like water dripping from one of the wall-mounted units. It probably is water: a condensate line runs from the back of the unit through the wall to the outdoor cabinet. If this line is leaking, it will put the operation of the blower unit in jeopardy, not to mention make it easier for mold and mildew to start to form around it.

A blower unit is sagging

This might be due to poor installation. If the installers didn’t properly secure the frame for the blower unit to the wall, it will eventually begin to droop. This sag can also be the fault of a condensate leak behind the blower that you haven’t noticed yet, but which is damaging the wall. If this isn’t professionally fixed, the unit will tear off from the wall and fall, taking part of the drywall and building material with it.

A unit isn’t sending out enough warm air

As you switch the blower units to heating mode, you might find that one or more is not giving out the heat it’s supposed to. If it’s only happening with a single unit, the first thing to check is the filter. Open the front of the unit and take out the air filter to see if it needs to be cleaned. (If you hold it up to the light and it blocks the light, it needs to be cleaned.) Gently wash it in water and leave it to air dry. Only replace it when it is fully dry. If this doesn’t solve the problem, the unit may need to have its coil cleaned. If all the blower units of the ductless system are failing to provide enough warmth, something may be wrong with the outdoor unit or the system is losing refrigerant. Call our technicians to diagnose the trouble and fix it.
