Heating System Trouble in Columbia SC: Five Signs You Need HVAC Repair

November in Columbia, SC, brings crisp mornings, chilly evenings, and a cozy reminder to check your heating system before winter fully sets in. From Lexington and Pelion to Redbank, Cayce, and Blythewood, homeowners rely on their HVAC systems to keep their families comfortable. But what if your heater is quietly struggling?

1. Rising Energy Bills

If your heating bills spike even though your usage has not changed, it may be a sign of inefficiency. Common causes include:

 

  • Clogged filters or dirty coils
  • Low refrigerant or gas supply issues
  • Leaky ducts
  • Worn components like motors or thermostats

A professional tune-up from T & T HVAC can restore efficiency and save you money before it gets colder.

2. Heater Runs Constantly but Does Not Heat Enough

Man Shivering Cold

Does your system seem to be working nonstop without warming your home? This could indicate:

 

  • An undersized unit
  • Airflow issues from blocked vents or ducts
  • Thermostat problems
  • Poor insulation or air leaks

We can evaluate your system, balance airflow, and make sure your home stays cozy all winter.

3. Strange Sounds or Smells

Your heater should operate quietly and cleanly. Be alert for:

 

  • Banging, rattling, or grinding noises
  • Burning or musty odors

These symptoms may indicate loose components, worn parts, or even mold in the system. Early repair keeps your home safe and comfortable.

4. Uneven Heating
