Q:Why is the air flow from my floor registers not satisfactory?
A:This can be an indication that the furnace filter needs to be changed. Turn off the furnace to check the filter. If it appears dirty, change the filter.
Q:I just turned on my central air conditioner for the first time this year. Why does it appear nothing is happening?
A:Ensure the furnace is switched on and the thermostat has been changed from ‘Heat’ to ‘Cool’. Also, ensure the outside unit is placed in the ‘On’ position.
Q:It seems like my thermostat is not working while the display is flashing. What is wrong?
A:Many modern thermostats operate on batteries. Remove the cover on the thermostat and replace the batteries with AA batteries.
