Heating Systems FAQ
You can make your heating system operate more efficiently and lower your energy bills by performing basic maintenance, upgrading your controls, and sealing your home against heat loss.
If your heating system is more than 15 years olds, a new unit could save you up to 20% on your annual heating gas consumption, depending on the efficiency rating of your current unit.
An energy efficiency rating is a standardized measure indicating how efficiently a product uses energy. The higher the rating, the more energy efficient the unit is and the lower the fuel bills will be, assuming the system is regularly maintained.
AFUE stands for “Annual Fuel Utilization Efficiency”, which measures how efficiently a furnace converts fuel into usable heat for your home. A higher percentage means less wasted energy and lower fuel bills.
For Example: A furnace with an AFUE of 95% converts 95% of fuel into heat, wasting only 5%.
To buy the right size heating system, balance your home’s square footage, local climate, and insulation quality through a professional Manual J Load Calculation rather than relying purely on size.
Many factors are taken into consideration to properly size the equipment for your home. An experienced heating contractor will calculate what size and type of heating system is best for your complete comfort.
Hot and cold spots in a house usually happen because of restricted airflow, leaky ductwork, poor insulation, or an improperly sized HVAC system. The solutions range from simple and cheap, to complex and expensive.
