Ductless mini split heat pumps are fantastic systems. The ability to both heat and cool your home is something you don't get with central air conditioning or a furnace system. Here in Garland these units are becoming more and more popular, especially for new homeowners doing new builds, or retrofitting an old outdated space. When building a new home or buying an older home, you have to consider if the space has or if you want to add a central ducted system. This is expensive, and the majority of residents here in the Garland area would opt to install a ducted central cooling system if they don't have to. This is why ductless heat pumps are so popular nowadays, because they are easy to install and don't require air ducts. But like any air conditioner, these systems require seasonal and yearly maintenance to run at their best capacity. You should always schedule mini split maintenance with a certified professional. Air Central HVAC is your mini split expert here in the Garland area!

Maintenance For Your Mini Split

We offer an Extensive Maintenance Agreement program, which will vary slightly in each ductless maintenance instance but usually follows along this checklist:

  1. Clean the wire mesh pre-filter and the electronic plasma indoor air quality filter inside the air handler.
  2. Clean the indoor air handler coils. The coils are vacuumed for dust, and specialized solvents are used to clean away residue. The technician also will look for signs of oil seepage that indicate refrigerant leaks in the coil, and use a fin straightener to straighten any bent aluminum coil fins.
  3. Inspect the condensate drain pan for evidence of mold or algae that could block the drain. Proper function of the condensate drain will be verified.
  4. Check the fan blower for buildup of residue from the room air and for proper balance. Lubricate the blower motor and check drive belt for tightness.
  5. Trace the refrigerant lines leading to the outdoor condensing unit and inspect for kinks, bulges, missing insulation or signs of refrigerant leakage.
  6. Verify that airflow to the condenser coil is not obstructed by weeds or vegetation. The technician will clean the condenser coil, straighten any bent coil fins and verify that the condenser unit is level on its platform.
  7. Check all electrical terminals for tightness and apply insulating coating.
  8. Measure airflow from the air handler to verify that it’s within manufacturer’s specs.

As a homeowner with a ductless mini split system we recommend a few things to do to keep your system running well between professional check ups -

  1. 1. Keep the Outside Clean: Making sure your unit doesn't gather dust and debris is a great thing you can do to keep your system running well. You can simply wipe down the unit once a week with a gentle cleaner, the outdoor portion and indoor.
  2. 2. Give Them Some Room: Not placing your mini split directly next to other system is a good idea. The unit should have ample space surrounding, at least 4 feet in every direction.
  3. 3.Change Your Filters: Filters for your system are very important, and they wear out. Dirty filters means less air is able to pass through the system resulting in less effective and efficient operation. Use a clean dry cloth to wipe your filters clear of dirt and dust, or change them completely if they need it.

Cleaning the coils, condensers and pipes of your mini split is also recommended to do every 6 weeks or so, but if you are uncomfortable performing those tasks we are just a call away.
