When the temperature plummets during New Mexico winter, it’s natural to expect your home’s heating system to  immediately start delivering warm air but if your heater is blowing cold air instead, you’d be right to be upset. Technicians at Affordable Service Heating and Cooling frequently get calls from anxious homeowners reporting this problem. They’re frantic that their HVAC system is broken when they need it the most. To ease your mind, here are common reasons why your heater could be blowing cold air. In some cases, you may be able to fix the problem yourself!

Typical Reasons a Heater Blows Cold Air

The first thing an Affordable Service technician will check is the thermostat. Believe it or not, homeowners sometimes forget to verify if the thermostat is set to activate the furnace when the house reaches a certain temperature. When we service older homes, we also check the thermostat because some older systems don’t have hardwired power, they run on batteries.

Have you been changing the furnace’s air filter? A dirty filter will tend to make the furnace work harder. When the furnace starts to overheat, its safety mechanism will automatically turn it off. This is often the reason why furnaces blow cold air. The issue may simply be that the pilot light has gone out. Follow the manufacturer’s instructions for relighting the pilot if you feel comfortable with this task. Otherwise, call a professional to take care of it.

More serious problems, such as a broken electronic ignition or other failing components require the attention of an HVAC expert.

If your home’s heating system is blowing cold air rather than hot, and you have already determined that the problem isn’t with the thermostat or pilot light, it’s time to bring in professionals.
