3 ways to quickly and economically save big bucks on home heating and cooling costs

What would you rather do: Pay your utility bill or take a much-deserved vacation? With an endless stream of bills each month, you might wonder where you can find the money to jet off to the beach or mountain resort of your dreams. There is a solution.

The average U.S. household spends more than $2,200 yearly on energy bills, with about half of that for heating and cooling, according to the U.S. Department of Energy (DOE). As a large portion of that energy is wasted, making your home more energy efficient will pay big dividends.

With only a couple weekends of work, these three simple low-cost DIY projects can significantly reduce your home cooling costs, freeing up money year after year so you can take vacations or do other fun activities. Best of all, the three actions work together to not only reduce your utility bills, but to make your home more comfortable year-round.

1. Add insulation

Chances are your home lacks sufficient insulation, despite when it was built. Some 90 percent of U.S. homes are under-insulated, reports the North American Insulation Manufacturers Association (NAIMA). Fortunately, adding insulation is simple, with products readily available at your local home improvement store.

One of the most cost-effective and easiest types of insulation to work with is expanded polystyrene (EPS) rigid foam boards. EPS panels are simple to cut to size without creating a mess, are recyclable and can be installed throughout your home, including in walls, floors, ceilings and foundation walls. A similar material, graphite polystyrene (GPS), also is easy to work with, and provides even higher insulating power, according to manufacturers. One of the EPS and GPS brands available at home improvement stores such as Home Depot and Lowe’s is R-Tech insulation from Insulfoam. “R-Tech EPS and GPS insulations offer some of the highest insulating power per dollar,” says Michael McAuley, Insulfoam general manager.

2. Seal air leaks

While inadequate insulation allows heat to pass out of your home in winter or to come in during summer, another path for energy loss is air leaks. Insulating your home and sealing air leaks can save you up to 20 percent on home heating and cooling costs, notes the DOE. Common places to look for leaks include attic access hatches, around windows and doors and in crawl spaces. Readily available weather stripping, caulks and spray foams can help keep your home airtight. For step-by-step instructions, consult the U.S. Environmental Protection Agency’s “DIY Guide to Sealing and Insulating with ENERGY STAR."

3. Install a programmable thermostat

With your newly insulated and sealed home, a third step you can take to cut energy bills is to install a programmable thermostat. The DOE estimates you can save as much as 10 percent a year on heating and cooling costs by simply turning your thermostat back 7-10 degrees for 8 hours a day. In the summer, keep your house warmer than normal when you are away, and set the thermostat to 78 degrees when you are at home and need cooling. Set your thermostat at as high a temperature as comfortably possible. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.

These three utility bill-busting tips are within the skill set of many homeowners, but if you want a little extra help, hiring a contractor is also cost effective, as these are not large projects.
