  • 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.
