Denver, NC, area residents often experience reasonable daytime high temperatures during the winter months, but it’s a completely different story at night. From December – February, it’s common for overnight temperatures to drop down into the low 30s. Therefore, it’s imperative to pay close attention to any heating issues before you end up with a broken HVAC system. Learn how to tell if heater repairs are necessary with this quick guide to the most common signs of mechanical issues.

A Noisy Furnace

When a furnace is operating properly, you shouldn’t hear lots of rattling, rumbling, or squeaking. These sounds indicate a possible mechanical issue. Other potential issues that may be uncovered by expert HVAC services include a clogged burner or airflow restrictions.

A Blower That Constantly Runs

Always check the thermostat when a blower won’t stop running. In many cases, the thermostat’s setting will merely have been bumped from “Auto” to “On.” You may also see speed settings such as “Low,” “Medium” or “High.” Any setting other than “Auto” or “Off” will keep the blower running continuously, which will increase your energy bill.

If the thermostat is set to “Auto” and you’re still experiencing blower issues, be sure to contact a professional HVAC technician. The odds are high that there’s a problem with the unit’s limit switch. Once the repair is completed, your energy bills should come back down to normal.

A Pilot Light That Frequently Goes Out

Be sure to check your fuse box and pilot light if your heater stops working. If the pilot light or electric ignition starts going out frequently, you could be facing a variety of necessary heater repairs. For instance, a faulty thermocouple can cause the pilot light to go out. Clogs or drafts could also be responsible for pilot light outages.
