While an air conditioner’s efficiency is measured by its SEER (Seasonal Energy Efficiency Ratio) rating, an electric or gas- or oil-fired furnace’s efficiency is measured by its AFUE, or average fuel utilization efficiency. This standard measurement is given in percentages, letting you know how much of your fuel is actually used to heat your Mississippi home and how much fuel is wasted. The higher the AFUE rating, the more efficient the unit is. Typically the ratings or percentages you’ll see on new furnaces range from 80 to 100 percent (contingent upon the fuel type of furnace being rated). If a furnace has an AFUE of 80 percent, this means the furnace converts 80 percent of the fuel to heat your house, while the remaining 20 percent is lost, usually out the chimney.

Upgrade your furnace for increased energy efficiency and heating cost reduction.

It’s normal for your furnace to make some noise. For instance, a dull hum is to be expected. However, louder noises might spell trouble for your heating unit’s components. Remember to turn off your furnace if it makes any alarming sounds and leave the repair job to a professional.

Maintaining your heating and cooling equipment ensures it’ll run smoothly the way it should when you need it. Investing your time and money in these seasonal maintenance tasks goes a long way to protect both your Mississippi home and your HVAC investment, including your wallet. Well-running systems are more energy efficient, so they end up costing you less to run all season long.
