5 Reasons a Furnace Might not Produce Heat During Winter

There are plenty of heating options in the market. However, whatever your customer’s choice may be, regular maintenance is key to quality service and longevity. The cold part of the year is already here, and it’s the perfect time to check your furnace, even if there weren’t any problems last year. There are a number of issues that might cause the furnace to stop working properly.

A furnace may blow cold air for several reasons, and the customers don’t need to be experts to understand something is wrong. If the customer’s furnace is blowing cold air, it’s time to contact experts and let them do a thorough checkup. Before doing so, it is crucial to equip them with proper knowledge and know-how on how to recognize furnace issues before they grow quickly.

Customers are not expected to know how to repair broken furnaces. Still, being able to recognize issues might help quicken the resolution. In this situation, your role is to inform them of all the common issues that may occur with their furnace and to have them contact you if they notice anything wrong.

An improper thermostat setting could cause the furnace to blow cold air. It is imperative to ensure that the fan blower switch is not set to “on.” If the auto setting is selected, the fan will only run during heating cycles and will not push air that feels cooler through the vents between heating cycles.

A malfunctioning thermostat could also cause your home’s furnace to blow cold air because it isn’t receiving the correct information to heat the house. Customers can solve this problem by contacting a HVAC company to install a smart thermostat.

  • Pilot Light Is Not Working

Customers might experience cold air if their furnace’s pilot light doesn’t work. You will need to relight the pilot light in this case. Your furnace’s thermocouple may be faulty if it doesn’t light. Your electric furnace can blow cold air if its heating element is damaged.

When either of these problems occurs, the customer should contact a professional to replace the heater element or pilot light.

  • Flame Sensors Need Cleaning

An electronic flame sensor is located at the bottom of the burner assembly. It is used to detect flames in a gas furnace. The dirty flame sensor will trigger the furnace to turn off after a few seconds since it cannot detect a flame. Cold air may blow through the vents as a result of short cycling. A professional HVAC technician can clean or replace the sensor to get the heating back to normal.

  • Control Panel Issues

It’s possible that your furnace’s electronic control panel is malfunctioning if it’s not warming your home. A system reset may resolve the issue. However, if the problem persists, a proper HVAC technician can resolve control panel issues. 

  • Clean or replace the HVAC filter

A furnace’s performance and air quality can be ruined by a dirty or clogged HVAC air filter. When the furnace’s filter is clogged, the unit must work harder to reach its assigned heat levels, which may lead to overheating and more serious breaks. Chances are it will stop working entirely due to overheating. The solution is to regularly check and replace filters, especially before the start of an active season. You can schedule a thorough checkup with a professional.
