Replacing the old furnace in your central heating system with a new, more efficient model can offset volatile energy prices. Money aside, today's furnaces pollute less and boost comfort by producing heat more steadily than older furnaces. Size matters--a lot. A furnace that's too small will struggle to keep up with the demands of your home, keeping your house less comfortable during cold weather and running more often than it otherwise need to. A furnace that's too large will cycle on and off more frequently. That puts more wear on its components, wastes energy, and might cause the temperature to vary uncomfortably.
We take the time to calculate your heating needs according to industry standards such as "Manual J HVAC Residential Load Calculation" of the Air Conditioning Contractors of America. We properly evaluate the size, design, and construction of your house to ensure we recommend the right size furnace to meet your needs. Once the furnace is installed, we offer cost-effective preventive maintenance (according to the manufacturer's recommendations) to safeguard and extend the life of the equipment.
Efficiency Also Matters
Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.
Furnaces have become more energy-efficient over the years. A gas furnace made in the early 1970s typically has an AFUE of about 65 percent. The lowest efficiency allowed by law for new gas furnaces is 78 percent, and some new models achieve 95 percent--near-total efficiency.
We can help assist you pick the model that’s right for you and your home. We’ll calculate the annual estimated operating cost of each model you’re considering. We’ll plug in information on each unit’s AFUE and electrical consumption, local utility rates, and characteristics of your home into our software to easily calculate very accurate estimates.
