It’s fifty degrees outside and your feet are chilly. You turn on the heart only to realize your heater’s blowing out cold air! What on earth?Cold air coming out of heating systems is a surprisingly common call we get at MTB Mechanical this time of year. If you’re facing this issue, here’s what to do.
First, double check to make sure you’ve set the thermostat higher than the actual temperature of your home! (It happens.) After you’ve done that, notice whether or not your thermostat is working correctly. Some thermostats run off central power, some have battery backup, and some only use battery power; if yours is battery powered and dead, you may just need some new juice.
If these simple fixes don’t do the trick, you’ll want to call in a professional HVAC technician. There are a number of things that could be causing your cold air conundrum, including:
Leaky Ductwork: If your ducts have come disconnected or a duct has sprung a “leak,” cold air could be getting in then circulating through your HVAC system. The attic is the first place to look for this kind of problem.
No Fuel: If you’ve got a gas or oil furnace, your system may not be getting the fuel it needs to operate efficiently. A technician will check your pilot light to ensure it’s on, then make sure the gas or oil is flowing smoothly.
Shorted Components: If you’ve got a relatively new (as in, less than ten year old) heating system, some of its electrical components may have gone out. A professional can determine which parts need fixing and which should be replaced.
Need New HVAC: There’s a possibility that a heater blowing cold air is simply a sign it’s time to invest in a new heating system. Most heaters are graded to last anywhere from 10-12 years, but use, wear-and-tear, and other factors can play a role.
MTB Mechanical understands that when you need heat, you need it now. Our team of licensed technicians is ready for your call 24/7. And remember, the best way to avoid a costly heating repair is to have your heating system checked at least once a year! Proper preventative maintenance can save you thousands in the long run.
