Switch The Thermostat Setting

If your furnace is blowing cold air, the first thing you should do is check the thermostat. If your thermostat is set to “fan-only” mode, this could be preventing the furnace from heating your home. Switch the thermostat to “heat” mode.

Clean Or Replace Air Filters

A dirty air filter can often be the cause of many furnace heating issues. If your air filter is overheating due to built-up debris, this can cause your furnace to blow cold air. Simply swapping the dirty air filter with a clean filter may solve the problem.

Properly Maintain The System

Properly maintaining your furnace should include thoroughly cleaning all the parts and having an annual maintenance check from a professional. For simple furnace repair, JDL HVAC offers a heating maintenance service to ensure your system is working properly so you can stay warm all winter long.

Reset The High Limit Switch

Before you think you have a broken furnace, it may have just overheated. When your furnace’s high limit switch trips, the furnace will blow cold air instead of hot. If this is the case, reset the high limit switch to prevent your furnace from overheating and destroying itself. This is a quick and easy fix to make sure your furnace is working properly without having to call a professional.
