While it is best to leave HVAC inspection to a qualified technician, there are some ways to evaluate your heating system’s efficiency on your own. Here are some red flags that suggest your heating isn’t working properly:
1) If you’ve noticed your heating bills are abnormally high, this means that your heating system is not operating as efficiently as it used to.
2) If you can hear bizarre noises or feel burning odors when your heating system is running, this is a warning sign that it is nearing the end of its service life.
3) Are some rooms colder than others? Have you started to turn up the thermostat more often than before? If the answer is yes, your heater may not be running efficiently.
These and other symptoms indicate that you need to call a HVAC specialist to schedule a heating system check.
