What Makes a Furnace Blow Cold Air in Martinez, GA?

It’s cold outside, and you’re trying to stay warm, but the furnace is blowing out cold air. You might have a problem with your furnace in Martinez, GA, which an expert can fix in one of two ways: by locating the issue or replacing the entire unit. To find out what’s causing this problem, read on.

Issues With the Thermostat

The controls of a furnace are typically a thermostat. The purpose of the thermostat is to regulate the temperature by turning the heating system off and on as necessary. However, there are many times when the thermostat can have an issue that will cause it not to work correctly.

If this happens, your home will have no heat until you notice what has happened or someone else notices for you. To help prevent these issues from happening in the first place, homeowners must learn about their systems and how they work before anything goes wrong.

Dirty Air Filter

The furnace in your home may blow cold air because the filter is dirty. Filters have a design that helps to take out particulates, such as dust and allergens, from the air before entering the furnace.

If these particles enter the furnace filter and continue to build up, the filter will become thickly coated with dust and dirt. It can then restrict the airflow into your furnace causing a decrease in effectively heating your home and reducing its efficiency.

The problem with this scenario is that dirtier filters mean more work for your HVAC system, which means higher energy costs. It’s essential to clean your filter regularly, usually every quarter, but more frequently, if needed.

Gas Pressure Regulator Valve (If the Furnace Is Gas)

A gas pressure regulator valve can be a complex part of the furnace. If this mechanism doesn’t work correctly, you may find yourself dealing with cold air blowing out of your vents even when the heating system is set to “heat.” To fix this problem, a technician will adjust the settings so that they’re at an equilibrium again. A technician will also thoroughly check out the system to ensure there aren’t any other issues or problems.
