Can I Troubleshoot Before Calling Mt. Vernon?
The answer is, "Yes." Here are some simple procedures you can perform before going to the expense of a service call:
In addition to the routine maintenance you perform, your home comfort
system should be inspected at least once a year
by a properly trained service technician. Mt. Vernon
can make sure your system operates safely and gives
you the best performance at the lowest cost. You
may also want to ask
us about an economical service contract that
covers seasonal inspections for a flat fee.
- Check disconnect switches (indoor and outdoor if you have a split system). Make sure that circuit breakers are ON or that fuses have not blown.
- Check for sufficient airflow. Make sure air filters are clean and that supply-air and return-air grilles are open and unobstructed.
- Check the settings on your thermostat. If you want cooling, make
sure the temperature control selector is set below room temperature and the SYSTEM switch
is on the COOL or AUTO position. If you want heat, make sure the temperature control
selector is set above room temperature and the SYSTEM switch is at HEAT or AUTO. The FAN
switch should be set at ON for continuous blower operation or AUTO if you want the blower
to function only while the unit is operating.
