Looking for ways to lower your heating bill? You're far from the only one. The average heating bill for Americans is $1,500 year, according to HomeAdvisor. And for folks using gas instead of electricity to fuel their furnace, that bill is expected to surge. So while you can’t control oil prices, you can improve the way your home maintains heat and how you use it. We spoke to several pros for their expert tips—from bigger investments to simple swaps—for saving on the ever-dreaded mid-winter heating bill.

Sometimes you have to spend to save. At least that can be the case with lowering your heating bill. HomeAdvisor’s home expert Dan DiClerico recommends paying a professional to inspect your furnace each year. This can cost between $80 and $200, but you’ll find out whether anything needs your attention.

Similarly, you should replace your air filter at the start of a season and at least once more during the colder months. You can get an air filter for $15, but if you can spare the money, upgrade to a nice one for $20 to $30. “New filters won’t save a lot of money, but you’ll usually break even,” DiClerico says. “That, and overall your unit will work more efficiently and ultimately last longer.”  It also pays to have someone look at your duct work. Fixing leaks in duct work requires a professional but can save hundreds of dollars a year, DiClerico says. “We know that as much as 30 percent of heated air is lost to leaks in ductwork,” he adds.

Think of your home as an envelope and make sure to seal all cracks, says Jeff Starkey, the vice president of Atlas Butler, a heating, cooling and plumbing company in Columbus, Ohio. Feel for drafts around pipes, doors, windows, and electrical and cable outlets, says Anne Marie Corbalis, spokesperson for Con Edison. Inexpensive draft blockers and outlet sealers can fix many of these problem areas.

“Make sure your window stripping and door stripping are in good condition, too,” Starkey adds. “When it gets cold out, these types of building materials shrink.” You can pay a professional to come in and seal cracks around windows and doors for about $250, or plan to spend the better part of the weekend doing it yourself, DiClerico adds.

Want a cheaper option? Starkey says to try a winterization kit. It basically involves shrink wrapping your windows in plastic for the winter. Doesn’t look pretty, but it’s effective, he says.

You’ll also want to make sure your home’s insulation is working well. If your home was built before 1980, it’s more likely to need an upgrade, DiClerico says. You’ll know you have an insulation problem if snow melts quickly off your roof or creates icicles. Sealing up these cracks can save about 10 percent of your monthly cost, DiClerico says.

And finally, draw the blinds at night. Definitely throw open blinds and curtains on sunny days—but close them at night to prevent up to a 10 percent loss in the room's heat. It's subtle habit changes like this that could help reduce the overall cost of your energy bill.

Most Americans have gotten used to warmer homes over the years, but DiClerico finds they’re spending too much to keep their homes at an unnecessarily warm temperature. He recommends keeping the temperature set to 68 degrees during the day, and lowering it to 60 degrees at night. If that’s too cold, grab extra blankets. “Since the start of central heating in the 1960s, average home temperatures have gone up to 70 degrees during the day and 68 overnight,” he says. “A lot of families disagree on the temperature and we hear about thermostat wars, but you can’t argue that this measure will save.”

Shutting your heat off if no one is home during the work day is another way to save. Starkey says this is where a smart thermostat can help. Program yours to kick back on about 30 minutes before you get home, so the house is toasty again. “You can save up to 20 percent on your monthly bill,” he says. That's usually enough savings to break even on the investment of a smart thermostat in your first year.

While it might make sense to to save on heating by shutting the furnace off in favor of a concentrated space heater, say in the bedroom, Starkey warns against it. “You’re basically heating your home with a toaster,” he says. “You plug it in and the heat strips warm up. Air blows across those heat strips, but it’s a really ineffective method.”

Similarly, DiClerico warns against using the fireplace more than a couple times each year. “Everyone loves a roaring fire, but it’s by far the least efficient way to heat a home,” he says.

While it’s fine for ambience, DiClerico says to make sure your flue is closed when not in use—and don't forget to close the damper, too, says Lauren Urbanek of the Natural Resources Defense Council. Aside from inviting pests into your home, they allow hot air to escape and cold air to sneak in. You can also hire a pro to make sure your chimney is properly sealed.

humidifier might help keep you warm without raising your heating bill quite so dramatically. “We try to get the humidity out of our house in the summer time because water holds heat,” Starkey says. “In the winter, we want to do the opposite: Put humidity in the air.” Corbalis adds that moist air feels warmer than dry air, so run a humidifier when the heat is on. This will also reduce pesky static electricity along with your heating bill.

Check to see if your utility provider will estimate your bill and usage. “Many utilities also offer ‘budget billing,’ where they look at your past usage and estimate an average cost for you to pay each month,” Urbanek says. “This will help you budget your monthly costs, but won’t actually save energy or money,” she says. Urbanek says other providers will offer plans based on the time of day when energy is used, with the idea that it’s more expensive to use electricity at peak times where there’s a lot of demand on the system.
