In Austin we typically want our air conditioners running, but there are still cold fronts that will make us switch the heater on. The last thing you want is your heater to be blowing cold air when you are trying to warm up.
Here are some reasons that your furnace might be doing that and how to troubleshoot the issues.
One simple fix could actually be at your thermostat. The thermostat might be switched to ON instead of AUTO. The ON setting means the fan continuously runs but is not necessarily blowing hot air. Switching it to AUTO will hopefully resolve the issue.
If you are still looking at the thermostat for furnace troubleshooting, try replacing the batteries and making sure it is installed correctly. If the thermostat is not communicating correctly then the whole system will be out of sync. You can have your system checked by a professional or replaced completely. You might even consider switching to a smart thermostat for more control over the settings and to save energy.
A pilot light is a small flame that is kept lit and is an ignition source for the bigger gas burners in appliances like the heating system in your home. If this flame was put out on accident (or even on purpose) it can be causing the cold air to blow.
This furnace repair might take some research, but if you are comfortable relighting it yourself it will fix your issue, but if not call a professional for assistance.
If your air filters are old and dirty, then it could be restricting the airflow into your furnace. This clogging in the air filter could cause your furnace to overheat and then only push out cold air.
This furnace troubleshooting is simple as you should just replace your old filters with new clean ones. To keep your HVAC system running smoothly get in the habit of replacing the air filters about every three to six months. This will also ensure your indoor air quality remains fresh and healthy.
Leaking ducts can be a cause of your heater blowing cold air due to the loss of heat. If holes are present in the ducts, then the hot air produced will be lost as it travels throughout. Then once the air is pushed into your room it will not feel as warm as you want.
Try to pinpoint these leaks and seal them. You can use HVAC Tape or duct sealant if you want to do it yourself or call a professional to get the repair done. If your ducts prove to be leaking a lot of air, it may be wise to replace the ductwork entirely.
If troubleshooting is unsuccessful call a technician at Go Green Heating and Cooling for the best furnace and AC repair services in Austin.

After receiving a ridiculously high quote from the HVAC company sent out by our home warranty, my husband wanted a second opinion. Our technician Mike was thorough and honest about what needed repair. Not only was the diagnosis much simpler, so was the price. Mike got the repair done quickly and was very professional. We’ll definitely be calling Go Green again.
