Find quick answers to typical heating and cooling concerns from Montgomery homeowners.
What Should I Do If My Furnace Blows Cold Air?
If your furnace is blowing cold air, the pilot light may be out, the ignition system may be faulty, or your thermostat settings may be incorrect. Turn off the system and call for service to avoid further issues.
How Do I Troubleshoot My Thermostat?
Check that the thermostat is set to the correct mode (heat or cool), verify the batteries aren't dead, ensure the temperature setting is appropriate, and make sure nothing is blocking the vents around the unit.
