Homes cost a lot of money to maintain. But are you spending extra money unnecessarily on upkeep? Here are seven of the most expensive mistakes you could be making in your home:

1. Using Traditional Light Bulbs.If you still have incandescent light bulbs in your home, you could be throwing a lot of money away every month on inflated electric bills. Over its life span, an incandescent bulb can use almost $200 worth of electricity. A CFL will only use about $40 worth of electricity over the same time period. Even better is the LED bulb, which only uses around $30 per bulb. Think what replacing every light bulb in your home could do to your home’s bottom line!

2. Letting Faucets Leak.A leaky faucet that drips one drop per second can waste more than 3,000 gallons per year, which is enough water to take more than 180 showers. Some people live in areas where water is plentiful, but for others in areas plagued with drought, this could be costing a fortune. Fix or replace your leaky faucet, and save a ton on your water bill.

3. Using the Wrong Air Filter Size.We all sometimes forget to change out the air filters for our HVAC systems or accidentally buy the wrong size. But using the wrong filter or a dirty one can increase your power bill and cause expensive problems for your furnace down the road. Use the correct filters for your system, and set a reminder to change them after the recommended amount of time. You won’t regret it.

4. Not Customizing the Temperature.Invest in a customizable thermostat. If you’re away at the office all day, you can program your heater to shift down a few degrees while you’re gone and then shift back up shortly before you return home. Heating or cooling an empty home wastes a lot of money in energy costs.

5. Not Adjusting Air Vents Properly.Is one room in your home hot, while the others are cold? Oftentimes homeowners will crank up the air conditioning in the whole house to combat hot temperatures in one area. Instead, adjust air vents to direct the flow of air more evenly throughout your entire home. Professionals will come regulate this to ensure your entire home is receiving the same amount of air conditioning or heating.

6. Overwatering the Lawn.Many homeowners have their sprinkler systems programmed to come on in the early morning hours for optimum lawn health. This can become a problem, however, if you’re never around to see what you’re actually watering. A broken sprinkler head could be causing a fountain, or the trajectory of your sprinkler may be directed at a fence instead of your lawn. Periodically run your sprinklers during the day so you can see how theyre performing when you’re not around.

7. Ignoring Leaky Windows and Doors.Leaky windows and doors are great places for cold winds or hot air to enter your home. Many homeowners simply ignore them and crank up their heaters or AC. Caulk leaky windows and put rubber seal around doors to maintain your indoor climate.
