Take a look in your attic. In most climates, you’ll find insulation about 12 to 15 inches thick, which provides insulation of about R38. This varies, depending on the climate, but 12 to 15 inches is a good rule of thumb.
If you don’t have that level of insulation or you don’t know where to look, seek advice from a professional. The pro will know the standards for your area and can give you good advice. Make sure the pro talks about air sealing between the heated space and the attic as part of the insulation system. Air sealing is just as important as insulation.
Set the thermostat Heat-Off-Cool switch to Heat. Check the fan switch – it should be set to Auto. Move the thermostat setting to a few degrees above room temperature. Normally the thermostat will display the room temperature, not the setting. Be sure the setting is above the room temperature, and give the furnace a few minutes to start.
If the furnace does not start, adjust the setting below the room temperature, wait a few minutes, then move the setpoint back above room temperature. This may reset the furnace’s controls so that it operates properly.
Still no heat? Change the battery. Never mind what your thermostat says. Change your battery every year! And while your at it, change your batteries in smoke detectors and Carbone Monoxide sensors. If you call for service, the first thing the tech does is change the batteries. Isn't this kinda the same as IT telling you to turn your computer off and turn it back on, when your having a problem.
