Dead Batteries in Thermostat
The first thing to check is the batteries in your thermostat. Low batteries can prevent your thermostat from working as it should. Most modern thermostats have a low battery indicator that lets you know to replace them. If you're not sure how to replace the batteries, consult the thermostat's manual.
Check Your Thermostat's Settings
Someone may have changed your thermostat's settings in a way that results in your heater blowing cold air. Make sure the temperature is set where it should be and not at a setting that turns on the air conditioner. The fan should be set to "AUTO" and not "ON" as, otherwise, it will blow air even when the heater isn't on.
Ductwork Issues
If a room in your home is suddenly cool, it may be because of a ductwork problem. Part of the ductwork may have fallen or vermin chewed a hole in it. An HVAC technician can solve this issue for you.
Triad Sheet Metal in Greensboro, NC can repair any issues with your home's ductwork. We've been helping people in the surrounding area since 1990.
Your System Is Overheated
Your heater can become overheated. There are safety systems that shut it down when this occurs. An overheated heater is often the result of a dirty air filter, mechanical failure and old age. An experienced technician can figure out what the problem is and provide you with solutions.
Dirty Flame Sensor
Furnaces have a flame sensor that ensures they are operating safely. A dirty flame sensor will prevent the burners from igniting, which results in cold air being pushed into your home.
The team at Triad Sheet Metal tunes-up, repairs and installs heaters and air conditioners. Other services we provide include indoor air quality, ventilation and roofing. Contact us today to schedule one of our services.

All furnaces should be serviced and maintained regularly to make sure that they continue heating effectively and efficiently. If you want to lessen the chances of your furnace breaking down over the winter, you should always have your furnace professionally serviced every year. In this post, we're going to discuss why furnace maintenance is important and what it involves.
The Importance of Yearly Furnace Maintenance
Furnace maintenance is essential for your safety. It helps to prevent possible fire hazards and carbon monoxide leaks. The technician servicing your equipment will always check that everything is functioning properly to ensure the furnace will automatically shut down if it overheats or experiences a safety issue. Maintenance is also important for the life of your furnace, ensuring it lasts anywhere from 15 to 30 years. It can also save you money by lowering your heating costs and helping to avoid costly repairs later on.
What Does Furnace Maintenance Entail?
Maintaining a furnace involves inspecting, cleaning and testing all of your heating system's components on an annual basis. This includes the various components inside the furnace, as well as the blower and thermostat.
A technician will inspect your ductwork to ensure it isn't damaged or leaking air. Damaged ductwork will greatly increase your energy costs and make your heating system far less effective.
Cleaning the blower assembly, furnace burners and flame sensor are especially important for keeping the furnace heating effectively. This also provides reliability. Inspecting the heat exchanger and exhaust flue is also essential for ensuring the furnace is properly vented and preventing carbon monoxide leaks.
