Basic Heating and Cooling Troubleshooting
for when you are not sure if the problem with your system warrants a service call
Your system will not turn on:
Check your emergency switch -Every
home has an emergency switch. The trick is knowing where it is. It is
most often a red-plated switch in the room with your equipment. It can
also be found on the unit itself or in a hallway leading to the utility
room/location of the units. The switch powers your furnace, boiler, AC
and utilities. It acts as an emergency shut off in an emergency
situation. Check to make sure the switch is in the on position. It can
be bumped or unknowingly turned to the off position.
Check for low batteries -One
of the most common issues we discover is that the batteries are low in
the thermostat. Although the it may not seem as though a low battery in
the thermostat will effect your furnace or A/C unit, it can and it does.
It is always worth a shot to change your batteries, even if the low
battery light is not on.
Check the circuit/s to your system -
If the circuit is blown, just reset it and try to see if the system
will start. Check the circuits for the thermostat and the heating or
system. photo by Paulo Ordoveza
Check the thermostat -
someone in the house could have adjusted the thermostat or bumped into
it turning it down or off. Make sure the thermostat is set to be on --
set for heat, cool or auto depending on which you are trying to use.
Also make sure the thermostat temperature is set to be cooler than the
temperature in the room (as shown on the thermostat) for cooling or
warmer than the temperature in the house for heating.
Check your filter -If
a filter is too dirty it may cause the air conditioner or furnace to
shut down due to lack of sufficient air flow. If the filter is dirty,
call us and we will come out to change it for you - 732-929-0380.
Check your returns - All return registers should be clear by about four feet of any obstructions.
