Editor’s note: Sure, you can live without air conditioning, even during brutal Summers like the one about to end. But no amount of natural cooling will lower the humidity in your home (or prevent things like mold growth that spring from that humidity). If air conditioning is necessary to keep your home free of such nastiness, make sure you’re taking care of your system: here are some tips for doing just that.

5 Tips for A/C Upkeep
By Katie Kretschmer for Home Rehab Online
Welcome to steamy August, when the last thing you want is for your air conditioner to conk out on you — especially with this Summer’s record temps across t he country. Whether you rely on a window unit or central air, easy A/C maintenance tips will keep the cool air flowing when you need it. We asked the pros for easy ways to ensure your system is running through Labor Day and beyond.
1. Change your filter
It’s the easiest thing you can do to ensure your system keeps you cool, says Bobby DiFulgenitz, director of product management at Lennox. “A clogged filter forces your system to work harder, using more energy,” he says. He suggests changing the filter on central air systems every other month — or more if you have pets that shed. Not only will you save money on your energy bill, you’ll be breathing cleaner air.
“Just make sure it’s the right filter for your model, but also the correct type of filter,” adds Terry Frisenda, regional account manager for LG Electronics USA Commercial Air Conditioning. He cautions that too fine a filter will make it harder for the unit to push air through. If you have a window unit, Frisenda says, “Simply wash and replace the filter — but be sure it’s completely dry before you put it back.”
2. Clean the coils
Like a clogged filter, blocked fins and coils on the outside unit can cause your system to work harder and subsequently break down, according to Frisenda. Use a nylon brush or broom and your garden hose — never a pressure washer — to rinse leaves, grass and other debris from the fins, he says. If you have a window unit, do this in the Spring, before you install the unit for the season, and again in the fall, before you put it away.
3. Remove obstructions
Make sure there is nothing blocking the flow of air around your outdoor unit: Any plantings, hedges or fencing you might have to hide your outdoor unit need to be at least 12 to 15 inches away, according to Frisenda. Inside, don’t cover your window unit with drapes or curtains when it’s on.
4. Program your thermostat
For a central system, set your thermostat to a slightly higher temperature during the day, when you leave the house, and a lower temperature when you get home from work, says DiFulgenitz. The newest thermostats are designed to be more user-friendly, and some even work via WiFi or your smartphone, so you can raise the setting when you leave to run errands, and then remotely turn it back down when you are on your way home. This lowers energy bills as well as reduces strain on the system.
Shut window units off when you are gone. “Window units are designed to cool a room quickly, and they also use a lot more energy, so it’s more efficient to turn it off,” says Frisenda.
5. Get a tune-up
The best way to keep your whole-house cooling system trouble free is to have an HVAC pro give it a tune-up once a year — in the Spring, before you need your A/C is best. “It’s like changing your oil in your car,” says DiFulgenitz, “and it helps everything run better and last longer.” As part of the tune-up, the contractor will check and clean filters, test the internal mechanisms and charge the unit with refrigerant. However, window units don’t need this. “And if anyone tells you they want to top off the coolant in your window unit, they are ripping you off,” says Frisenda.
More easy checks and fixes:
• Examine the cord on your window unit for frayed or worn spots. It may need to be replaced.
• Use drapes and blinds to block the sun from warming rooms so your A/C doesn’t need to work as hard.
• Protect outdoor units from corrosion — especially if you live near salt water — with paste wax. Just apply and buff it in, says Frisenda.
• Look for and seal air leaks around windows and doors with a caulk gun. “When cool air escapes, or hot air can find its way into your home, your air conditioner has to work harder to keep the temperature where you like it,” says DiFulgenitz.

I find that spraying the AC coils in a downward fashion is the best method for clearing the debris. Also, make sure to use a coil cleaner to remove oxidation from the metal surface.
wall unit air conditioners
Thanks for the good informative review. There are several pointers that are important to keep in mind when you are getting your wall unit air conditioner out and ready for the hot weather. The first one is to inspect it to see if you need to perform any cleaning of vents or other maintenance on it before testing it to see if it is ready to be turned on. Be sure to unplug the power before you work on it. A properly working in wall air conditioner will be clean and in good repair with no bugs or debris inside. There are some of the different things to check for wall air conditioner care, beginning with the fan and motor to see if they are clean and operational. If they need to be tightened or lubricated do so now. Check to see if the thermostat is operating correctly.
Throughout the warmer months it’s so important to make sure that your energy bill is just as comfortable as you are. They are many simple tips you can practice to remain cool as well as not go over your energy budget.
