Common Heating Problems in Kennesaw, GA: A Homeowner's Guide
Winter in North Georgia is unpredictable. One week we're enjoying a mild afternoon near Kennesaw Mountain, and the next, a "Blue Ridge freeze" sends temperatures plummeting. For Kennesaw homeowners, these rapid temperature swings place immense stress on heating systems.
If your furnace or heat pump is struggling to keep up, you aren't alone. Here are the most common heating problems we see in the 30144 and 30152 zip codes and how to solve them before they lead to a total system breakdown.
1. Iced-Over Heat Pumps
Most homes in newer Kennesaw developments rely on heat pumps. During a Georgia cold snap, moisture in our humid air can freeze on the outdoor coils. While your unit has a "defrost cycle" to handle light frost, heavy ice buildup often indicates a faulty defrost board or fan motor. If you see your unit encased in ice, shut it down and call a professional to prevent compressor damage.
2. Short Cycling (The "On-and-Off" Struggle)
Does your furnace turn on for three minutes and then abruptly shut off? This is called short cycling. In Kennesaw's humid climate, dust and pollen can rapidly clog air filters, restricting airflow and causing the heat exchanger to overheat.
The Fix: Check your filter! A dirty filter is the #1 cause of emergency service calls in Cobb County.
3. Ignition and Pilot Light Failures
If you have an older gas furnace, the pilot light may flicker out due to drafts or a dirty thermocouple. In modern systems, the hot surface ignitor—the component that glows to light the gas—is often the culprit. These parts have a limited lifespan and typically fail during the first major freeze of the year when they are forced to work overtime.
4. Inaccurate Thermostat Readings
Kennesaw homes with older thermostats often experience "cold spots." If your thermostat is located near a drafty window or in direct sunlight, it may give false readings to your HVAC system. Upgrading to a smart thermostat can help balance your home's climate and save up to 15% on winter energy bills.
5. Carbon Monoxide Risks
Safety is the most important part of "Expert" service. Cracked heat exchangers are a serious risk in aging furnaces. Because carbon monoxide is odorless and colorless, it is vital to have a professional inspection once a year to ensure your system's combustion process is venting correctly.
