If you’re finding your air conditioning window unit or central system appears to not be working as efficiently as it once was, check one thing before calling the repairman. Air conditioning systems have air filters that need to be cleaned or replaced regularly. A dirty air filter can force a system to work harder, which means it uses more energy and can also prevent your home from cooling down. Turn off the system or air conditioner and remove the filter; if it’s dirty, replace it. Then turn on the system to see if it makes a difference.

If you have a backyard pool, it can be a real energy hog to keep clean, heated and running. One way to cut back on energy usage is to reduce the pool filtration time by 30 minutes at a time. Keep reducing the pool filtration time in 30-minute increments until you notice the pool water needs to be cleaned. Instead of having the filtration running 24-7, you may find you can cut the filtration time by as much as two-thirds, which will still keep your pool clean and reduce the amount of energy used in upkeep.

Flimsy metal hangers you get from the dry cleaner can easily be returned to be reused, and they can be placed in your curbside recycling bin to be recycled. But you can also upcycle the hangers into stronger, no-slip hangers by wrapping pipe cleaners around the wire hanger. The wire inside the pipe cleaner will grip tightly on the hanger, and the fuzzy side of the pipe cleaner will help hold on to whatever you’re hanging.
