Why Is My Heater Blowing Cold Air?

When your heater starts to produce cold air when it’s running, the most likely culprits are your thermostat, furnace filters, or pilot light. If the thermostat is incorrectly set this will affect your home’s temperature, while blocked furnace filters will impact the system’s airflow and ability to adequately heat your home. Additionally, a pilot light that has gone out or extinguished will keep your property from receiving the heat it needs. However, these are not the only issues that can be a cause for a repair.

Common Heater Problems


With so many various working components that impact your home’s ability to heat, it’s best to bring in a professional Denver heater repair technician from our team at the first sign of trouble. We will be able to inspect and evaluate your unit to determine what could be causing the breakdown, providing the necessary fix to get the system back up and running. Try to avoid delaying a necessary repair as that can often aggravate the problem, leading to more expensive repairs down the line, and in some cases even result in a new heater being required.

Preventing Heater Breakdowns

We can help you keep your heating system running at peak performance with regular preventative maintenance service. Many equipment manufacturers require professional maintenance for the warranty, which is why we service all major brands and types of heating equipment.
