Unless you’ve been waiting patiently for your old, inefficient furnace to take its last breath so that you can finally upgrade to a new one, the thought of a major purchase like this will not likely fill you with joy. But don’t worry. We can help you navigate the options.
Be sure to weigh the increased upfront cost for a higher efficiency furnace against the increased energy savings you will enjoy over the life of the unit.
Your new furnace will be vastly more efficient than your old one, simply because technology has advanced significantly over the past few decades. There is, however, a broad range from the minimum-efficiency required to meet regulations and the top-of-the-line models. Greater efficiency translates into less wasted energy, better performance and lower operating costs.
Add an efficiency boost to your furnace by reducing the amount of work it does throughout the day. Programming your system allows you to effortlessly lower the temperature at night (the Sleep Foundation recommends temperatures between 60-67 degrees Fahrenheit for optimal sleep), and during the day when no one is home. For each degree you lower your thermostat during an 8-hour period, you can reduce your heating bill by about 2 percent.
Getting the correct size furnace for your home is the most important consideration. When it comes to comfort, a bigger furnace is not always better. When it comes to cost, a smaller furnace isn’t always more economical. Furnace size is measured in BTUs. Installing one that is too big will cause the unit to cycle more frequently, essentially making it work harder than necessary. This increases operating costs, puts you at risk for more frequent repairs, and can shorten the life of your furnace.
Three options account for varying degrees of comfort and efficiency.
Single-stage:
A single-stage burner is either fully on or off. This allows for more ups and downs in temperature, which means less consistent comfort. This type of furnace is the least efficient and will, therefore, have the highest energy costs.
Two-stage / Dual-stage:
A two-stage or dual-stage burner allows the furnace to run on high (full blast) or low. On milder days, the low setting keeps your home warm without using as much energy.
Modulating Burner:
A modulating burner adjusts to any level between off and high. This allows your furnace to always run at peak efficiency while keeping your home consistently warm and comfortable.
The type of blower (the part that actually blows the air into your room) also affects comfort and efficiency.
Single speed:
As the name implies, this type is either on or off. There is no middle ground.
Multi-speed:
This type has three speeds (low, medium, and high) to give you more control, and is more efficient than the single speed.
Variable speed:
This type has the ability to make incremental adjustments and is the most efficient.
Zoning is another way to improve the efficiency and comfort provided by your furnace, while reducing energy costs. By using multiple thermostats, you can control the temperature in different areas of your home independently of one another. Typically, two or three zones are created. Zoning by floor or separating living areas from sleeping areas are two examples. In this way, you aren’t paying to heat areas of your home when they aren’t being used, or you have the flexibility to allow for different comfort levels depending on how those areas are used. For example, you may prefer cooler temperatures in the bedrooms and warmer temperatures in the living areas.
Warranties vary by manufacturer and the HVAC company and/or installer, so make sure you are comparing apples to apples. In other words, be sure the warranties you are comparing are for comparable furnaces. More efficient (and expensive) furnaces tend to have longer warranties than basic models. Look for a long-term warranty on the heat exchanger.
Many high-efficiency furnaces qualify for rebates or other incentives from local utility companies. This means money in your pocket that can make a pricier furnace more affordable. Ask your HVAC professional what rebates and incentives are available.
Don’t make your decision based solely on price. An overpriced system and a system that is cheap can each be a poor fit for your home. Consider your needs, your budget, the purchase price, and the costs over the life of your furnace when making your decision.
Don’t skimp on quality installation. Proper installation is a key component of the overall performance of your furnace, the efficiency of the system, and the life expectancy of the equipment.
