People don’t often think about furnaces until they have to purchase new ones. Before you update your furnace, make sure you know what size you need for your home. Choosing the right model will keep you comfortable and save you money.
A Furnace That’s Too Small Can’t Heat Your Home Well
Keeping your family warm during winter shouldn’t take a lot of effort. Ideally, you just set your thermostat to a comfortable temperature and let your furnace do the work. Unfortunately, that won’t happen if you have a furnace that’s too small for your home.
Trying to heat a large home with a small furnace makes about as much sense as trying to warm your home with a hair dryer. No matter how long you let it run, it won’t get the job done.
When choosing a furnace for your home, though, you need to think about more than just the size of your home. You also need to think about how cold it gets where you live. If you live in a northern part of the United States where it tends to get quite cold during winter, then you will probably need a furnace that can generate 50 to 55 BTU per square foot. If you live in a warm climate, then your home probably needs a furnace that generates 30 to 35 BTU per square foot.
Furnaces That Are Too Big Can Waste Energy and Money
You need a furnace that’s powerful enough to heat your home, but you don’t want to choose a design that’s too big. Doing so can waste a lot of energy and money. Considering that the average home devotes about half of its energy use to heating and cooling, a furnace that’s too big for you could cost a lot of money over the years.
When comparing and contrasting furnaces, you should also look at the annual fuel utilization efficiency of each model. An appliance that’s 90 percent efficient devotes 90 percent of its fuel to keeping your home warm. The higher the percent, the more efficient the furnace is. You’ll save money for years to come by choosing an efficient model that’s appropriately sized for your house.
Choosing the Wrong Size Will Decrease a Furnace’s Lifespan
If your furnace isn’t the right size for your home, then you can expect to spend excessive amounts of money on repairs and maintenance. When furnaces are paired with the wrong homes, they often have to do more work than they were designed to handle. This quickly leads to mechanical malfunctions that can leave you chilly on the coldest winter days.
It’s best to talk to an HVAC professional who knows how to consider the effects of your home’s size and local climate. Without an expert’s opinion, you could find that you end up spending too much money on your next furnace.
The next time you wonder why you keep finding cold spots in your home or your winter energy bills cost so much, think about how your furnace’s size affects you. You may find that you can save money and live more comfortably by choosing a different size.
