- 2How to light the pilot light on an old furnaceOld furnaces often have hidden pilot assemblies or switches that fail to ignite even when following standard steps like holding the gas switch and hitting the igniter. This leaves homeowners struggling to figure out whether the system requires manual lighting or if there is a deeper mechanical failure, often forcing them to call a technician.
- 2Why is my furnace blowing cold air with a red blinking light?A furnace blowing cold air and flashing a red error code often indicates a tripped pressure switch or an issue with the inducer motor preventing ignition. This stops the unit from heating your home, leaving you with unheated air running continuously. Fortunately, some underlying causes like blocked tubing can be checked and fixed at home.
- 2Furnace won't turn on after new AC installationThe gas valve may have been left closed or something was missed during the recent HVAC installation, preventing the furnace from starting up when the weather turns cold. Homeowners worry that waiting too long to report the issue will make the warranty company or contractor upset about the delay.
