Common Furnace Problems We Fix in Summerville
At ServiceWorks Mechanical Solutions, LLC, our experienced technicians have seen it all and are equipped to handle a wide range of furnace malfunctions. If you notice any of the following signs, it’s time to call for a professional diagnosis:
No Heat or Insufficient Heat
A furnace that fails to produce heat or struggles to maintain temperature may suffer from issues such as a faulty thermostat, clogged filter, malfunctioning pilot light, or a failed blower motor.
Strange Noises During Operation
Your furnace should operate with a consistent, low hum. Unusual noises like banging, squealing, grinding, or rattling are indicators of mechanical trouble. Banging may point to duct issues or delayed ignition, while squealing often suggests a belt or blower motor bearing problem.
Frequent or Short Cycling
If your furnace turns on and off more often than usual, running for just a few minutes at a time, it is experiencing short cycling. This prevents proper heating, stresses system components, and increases energy costs.
Pilot Light or Ignition Issues
Older gas furnaces rely on a steady blue flame. A flickering, yellow, or frequently extinguished pilot light could signal thermocouple issues or ventilation problems, which may lead to carbon monoxide risks.
Thermostat Malfunctions
Sometimes the problem lies not with the furnace itself but with the thermostat. Faulty wiring, inaccurate readings, or power loss can prevent the furnace from receiving correct heating commands.
The Blower is Constantly Running
If the blower fan runs continuously, even when not heating, it may be due to a faulty limit switch or thermostat settings. This wastes energy and indicates an issue needing attention.

Should You Repair or Replace Your Furnace?
Many homeowners ask whether it is more cost-effective to repair or replace an older furnace. At ServiceWorks Mechanical Solutions, LLC, we help you make an informed decision by considering the following factors:
Age of the System
Furnaces over 15–20 years old are nearing the end of their lifespan. Major repairs may not be the best investment as more components are likely to fail soon.
Cost of the Repair
The “50/50 Rule” applies—if a repair costs nearly half the price of a new furnace, replacement is usually the smarter option.
Frequency of Breakdowns
Repeated repairs each winter can quickly add up. A new system offers long-term reliability and savings.
Energy Efficiency
Modern furnaces are significantly more efficient. Upgrading can reduce monthly heating bills, often paying for itself over time.
