Expert Furnace Repair in Gainesville, GA
When the temperature drops in Gainesville, a malfunctioning furnace isn't just an inconvenience—it becomes a serious issue that affects both comfort and safety. A silent or struggling furnace can leave your family in the cold and cause unnecessary stress. At Res Air LLC., we understand the urgency of furnace failures. Our team of certified technicians is committed to providing fast, reliable, and professional furnace repair services designed to restore warmth, safety, and peace of mind to your home.
Common Furnace Problems We Solve in Gainesville
Our technicians have the expertise to quickly identify the root cause of furnace issues and provide the best solutions. Below are some of the most frequent problems we address for homeowners in Gainesville:

Furnace is Blowing Cold or Lukewarm Air
If your furnace runs but only blows cool air, it may be due to a clogged filter, a faulty flame sensor, or issues with the pilot light. Our experts perform detailed diagnostics to identify and resolve the exact cause.
Furnace Won’t Turn On at All
Unresponsive furnaces often point to thermostat issues, power supply failures, or ignition problems. After checking basics such as thermostat settings or circuit breakers, our technicians can trace complex faults and restore system functionality.
Strange Noises from the Furnace
A well-functioning furnace runs with minimal noise. Unusual sounds often signal underlying issues:
- Banging or Popping may indicate dirty burners or expanding ductwork.
- Squealing or Whining often suggests a failing blower motor, worn bearings, or loose belts.
- Grinding or Scraping points to severe motor damage and requires immediate shutdown. We identify and fix these issues promptly to prevent further damage.
Frequent Cycling (Short Cycling)
If your furnace turns on and off too frequently, it could be caused by overheating, a blocked air filter, or a malfunctioning thermostat. Short cycling not only strains the furnace but also increases energy bills.
Pilot Light or Ignition Problems
Gas furnaces may fail to produce heat if the pilot light won’t stay lit or the ignitor doesn’t spark. Causes range from a dirty pilot orifice to a faulty thermocouple. These are safety-sensitive issues that require certified technicians from Res Air LLC. to handle.
When to Troubleshoot and When to Call Res Air LLC.
While certain issues require professional service, there are basic troubleshooting steps you can take before calling us:
Simple DIY Checks
- Verify that the thermostat is set to "HEAT" and the desired temperature is higher than the current room temperature.
- Inspect the air filter; a clogged filter can restrict airflow and cause overheating.
- Check the power switch and breaker to ensure the furnace is receiving power.
Call Us Immediately If
- You detect a gas odor or “rotten egg” smell—leave immediately and call your gas company before contacting us.
