Top Reasons Why Your Heater Is Blowing Cold Air

Your heating system should produce warm air to keep your home at the temperature indicated on your thermostat. If it’s blowing cold air, there could be something wrong with your unit or the thermostat.

In this post, Green Air Heating and Air Conditioning, Inc. — one of the area’s most trusted HVAC contractors — discusses the common reasons why this problem occurs.

Inaccurate Thermostats

Thermostat inaccuracy happens due to electrical or age-related performance issues. That said, technicians must check thermostats to ensure the accuracy of the device and your heating system’s energy efficiency.

Dirty Air Filters

Trapped dust and debris on air filters will cause heaters to work extra hard to warm your rooms. Clean or replace the air filter regularly to reduce energy consumption and achieve consistent temperatures.

Overheated Unit

An overheated system is often the result of dirt buildup, mechanical failure or age. You’ll need to replace air filters to remove dirt buildup or have an HVAC repair technician investigate why your heater is blowing cold air.

Clogged Condensate Drains

Condensation buildup will clog up the heater’s pipes. This is a typical symptom of an overworked heater, which is a common problem during winter. Call an HVAC company to remove the blockage in the condensate drains.

Pilot Light Outage

A pilot light outage will cause heaters to blow cold air. Have qualified technicians check the pilot light to know why it has failed and to restore your unit’s heating capacity. Smart HVAC system technicians can also mitigate the risk of further damage.
