HeatingWhy Is My Heater Blowing Cool Air?

When you need heating repairs, there are a few different warning signs that you may realize that can alert you to the problem. One of the most obvious signs, shy of a complete breakdown, is a heater that is blowing cool air from its vents. If this happens in your home, you can count on us to complete any repairs necessary.

There are also a few things that you should check prior to calling in a professional heating repair technician, though. Keep the following information in mind if you encounter this problem over the course of the winter. When you need heating repair in Everett, WA, you can trust our staff to do the job right.

Thermostat Settings

Our technicians are friendly and professional, but that doesn’t mean that you want to call them out to your home just for the company. If your heater is blowing cool air, give your thermostat a check before dialing our number. It may be as simple as a temperature setting that is lower than you intended. If you use a heat pump, geothermal system, or ductless mini splits, you may also have forgotten to switch the system back over to the heating mode. If there is no obvious problem at the thermostat, reach for the phone and give us a call.

Damaged Ducts

Is your home heating up, except for one area? If only a single vent, or those in one confined area, is blowing cool air, it could mean that the duct supply that vent is damaged. Professional duct repair or duct sealing services may be necessary to resolve the problem.

Flame Sensor/Thermocouple Problems

Your heater has a safety device, likely either a flame sensor or thermocouple, that will prevent the flow of fuel if temperatures are not hot enough to ensure safe combustion. The system will shut down, but may force some cool air through the vents before doing so. It may also blow cool air if the pilot is out. Because your safety could be at risk, such problems must be dealt with immediately.
