Common Problems

Newly Installed Equipment Malfunction

There are many service calls in which we receive for recently installed cooling equipment that is not working as expected. Most of these service calls are a result of poor installation of the newly installed cooling equipment.

If this problem is corrected early enough the life of the equipment could possibly not be negatively affected. Paragon Mechanical prides ourselves on expert installation of cooling equipment for each and every installation. See our cooling installation services for more detail.

Air Doesn’t Seem as COLD

Outdoor condensing units will when dirty run inefficiently and poorly. The outdoor units as they are providing cool air inside your home they are rejecting the heat from inside the home to the outside air via the outdoor condensing unit. When the condensing unit is clogged from dirt and debris it will not be able to reject the heat and therefore the cool air your home HVAC system is supposed to produce may feel warmer then usual because it can not reject the heat from inside the home .

The simply thing to do is clean the outdoor condensing unit. Paragon trained professionals can provide this service for you or we can show you how to do this yourself.

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.
