Our technicians perform detailed load calculations using ACCA Manual J guidelines to ensure your system is perfectly sized for your home. Whether your home needs a gas, electric, or energy-efficient furnace for your Opelika home, we’ll help you choose the right system based on insulation quality, building size, and ductwork condition.

Using advanced tools and planning software, we design an installation that meets all state energy codes and standards. From thermostat calibration and duct sealing to airflow balancing, every detail is handled to ensure quiet operation and even heat distribution throughout your home.

When Does Your Furnace Need Replacement?

Wondering whether it’s time for a full furnace replacement in Opelika or just another repair? Here are some clear warning signs:

  • Your furnace is 15 years or older
  • You’re calling for repairs more often than you’d like
  • You feel cold spots or uneven heating throughout the house
  • Strange noises, rattling, or humming during operation
  • Short-cycling (turning on and off frequently)
  • Rising energy bills
  • It just can’t keep up on the coldest days

Older systems naturally lose efficiency over time, which means more fuel is used, more money is spent, and the risk of breakdowns or even carbon monoxide leaks increases.
