The importance of maintaining and repairing your heating system

Your heater will attract unwanted elements such as debris or other harmful materials such as rust or mold through regular use. Because your heater also affects your air quality, it is important to clean your ducts to ensure good performance and health for your home. Additionally, periodic maintenance will ensure better unit longevity, so you don’t waste money consistently replacing or repairing your heater.

When to consider heating installation and furnace services

So when should you consider replacing your heater or looking for repairs? Simply put, when your heater no longer provides heat or you notice a leak. A malfunctioning heater will still require the same power as before but generate much less heat. Here are some common signs to look for:

Carbon Monoxide Leak

Many Charleston homes include natural gas-powered furnaces, which are effective and energy efficient but can also produce carbon monoxide. If not properly ventilated, the results can be catastrophic. If you notice any of the following, evacuate your home and contact Fix-it 24/7 immediately:

  • Yellow pilot light
  • Moisture on windows near the furnace
  • A feeling of nausea or light-headedness
  • Unusual rust on air handler/vent

Smells and Odors from Furnace

Your heater is tied to the central air system of your home, so if you notice a strange odor permeating from the heater, you should consider replacing it. The smell will be metallic, burning, or contain a stale odor like mold.  

Thermostat Adjustments

If your heater fails to reach your thermostat temperature or takes an increasingly long amount of time to reach the thermostat temperature, your heater will require repairs.  

Consistent Noises

Your furnace will start producing loud noises or run louder than usual. This is a clear sign that something is obstructed or the furnace is not running properly and will need to be repaired.

Rapid Cycle/Cold Spots

Your furnace should cycle on and off as it attempts to regulate the temperature within your home. However, this process should not happen in rapid succession. Rapid cycling is a sign that your thermostat or furnace is malfunctioning. Also, you should not feel cold spots throughout your home. Overall, the temperature in your home should be consistent. If there are cold spots, this will indicate issues with your duct system that require servicing.

High Power Bills

High power bills or spikes are a good indicator of something wrong with your heating unit. For example, a malfunctioning heating unit will continue to generate heat but require more power to generate the same amount of heat. If this continues, your power bill will continue to rise, and your heater can be damaged even further.

Burner Flame is Yellow

A yellow burner flame indicates that it is not receiving enough air. This is usually a sign of dirt build-up that is obstructing your heater. If this is untreated, you could have a large gas leak down the line or lead to an even greater disaster.

Your HVAC systems should be serviced every 6 months, once in spring and fall, ideally before summer and winter.

A furnace repair technician needs to have an HVAC license to repair any gas leaks or dangerous conditions. They work with all types of furnaces, including natural gas, oil, electric, and propane.
