When your heating,
ventilation, and AC systems have failed, reputable contractors can
surely restore them to tiptop shape. On the other hand, constantly
hiring contractors for minor repairs could wreak havoc on your
budget. To cut back on costs, it would be wise to arm yourself with
the basics of troubleshooting HVAC.
When the system
shuts down
If you feel that your
heater or AC fails to deliver the usual volume of air, then the
system must have deteriorated. To diagnose the problem, see if the
thermostat or the battery needs replacement. The problem could have
also been triggered by a blown fuse so it’s best not to miss out on
the main power panel.
Fuel is down
Traditional HVAC units
are typically powered by gas and oil. When there is insufficient
supply of fuel, the heating or AC unit will become inefficient. Check
the gas lines of your furnace to ensure that the fuel flows freely.
If something is blocking the pathway of the fuel, seek the services
of an experienced repairman.
Check service door
The safety switches of
indoor furnaces and AC units are placed on their service doors to
make the operation a lot easier. Essentially, the system
automatically shuts down if the door is opened. If you feel that
there is not enough airflow, check if you have unknowingly opened or
loosened the service door.
