There are many advantages to mini-split systems, as long as they are working properly. Many mini-split models can have as many as four indoor air handling units (up to four zones or rooms) connected to one unit. This number will depend on how much heating and cooling is required for each room. Additionally, mini-split systems have the ability to improve indoor air quality, allowing you to breathe happily. Mini-split systems save you money and allow you to lower your carbon footprint through ductless cooling. Here at Paragon Mechanical we want to make sure that you are taking advantage of all the benefits that your ductless cooling system has to offer. Whenever a problem arises, contact Paragon for a professional mini-split system repair.

  • Common Problems +

    Blank Thermostat

    When installed, some standard thermostats require a battery to keep them working. If you see a blank screen on your thermostat, the first thing you should try is to simply replace the batteries. Thermostat battery failure is oftenly mistaken for a major furnace problem.

    Visit our Smart Thermostat page to learn more about cutting-edge thermostats that are internet-connected, provide remote access, and no longer require batteries to operate.

    Warm Air in Cooling Mode

    A conventional split cooling system has an outdoor condensing unit and an indoor furnace. If you notice warm air blowing from your vents, and the outdoor condensing unit is not running, please check the corresponding breaker to ensure the breaker has not been tripped. Before resetting the breaker, you should try to determine why it was tripped, correct the issue, and turn the breaker back on.

    If the problem persists or you are not comfortable rectifying the problem yourself, please contact a trained, Paragon Mechanical, representative or technician to assess and correct the problem.

    Ice Present on Unit

    Ice formation can be caused by many factors, but one of the most common causes is a lack of air flow inside of the indoor unit. Poor air flow is commonly caused by a dirty filter. Before calling a professional, you should check your filter, replace it if it is dirty, and let the system completely thaw before attempting a restart.

    If our quick solution does not work for you, please contact Paragon Mechanical to arrange a service call. The Paragon Mechanical Service Agreements are also a fantastic way to stay ahead of filter-related problems.
