Five Easy Air Conditioner Maintenance Tips

There are few routine household maintenance chores that pay off more than keeping a maintenance schedule for your air conditioning unit. Not only will you give yourself the best chance at staying cool all summer and avoiding emergency breakdowns, but you’ll also save money on your energy bills.

A well maintained AC unit will run more efficiently, use less energy, and cost less money to run. A properly maintained system will also last longer before needing to be replaced.

AC Tip #1: Clean and/or Replace Air Filter

Replacing your air conditioner air filter (or cleaning it, if you have a reusable filter) is one of the most important regular AC maintenance chores. It should be done every month during high-use seasons (like summer and winter) and once during the fall and spring.

Changing AC air filter in attic.

The air filter will be located either:

    • Behind the return air grille on a wall or ceiling in a central room of the house.
    • Inside the blower compartment of the air handler or furnace.
  • In a slot on the side, bottom, or top of your furnace.

When the filter becomes full of dust, dirt and allergen particles, the air flow will decrease, making your system work harder than it should have to. The air flowing through your system may also become dirtier, dustier, and prone to triggering allergy and asthma symptoms for those residing in the home.

AC Tip #2: Check Wiring and Components

Before working on an air conditioner, ALWAYS start by turning off the power to the unit, which can be done at the service disconnect on your outdoor unit or at the main breaker panel of your home.

Old wiring inside AC unit.Next, remove the access panel on your condensing unit and see if you see any signs of overheating – melted insulation on wires, blackened or burned-looking wires, and the like.

You can also check any electrical connections to make sure they are tight. If you own an electrical test meter, you can check the capacitors in the unit.

Take a look at the contactor switch, and replace it if you see excessive pitting.

If you see any of the above problems and do not feel comfortable replacing the parts yourself, always call a local heating and air conditioning expert to do the work for you.

AC Tip #3: Examine Thermostat

Check your thermostat to make sure it’s working properly and keeps your home at the right temperature. If you have an older, mechanical type thermostat, you may want to consider upgrading to a programmable model.


A programmable thermostat allows you to set the temperature higher when no one is home (do not turn the AC off, just up), and cool the house down about 30 minutes before people arrive home for the evening.

That way you’ll always have a comfortable home waiting for you, and you’ll save energy and money by not having your AC running all day when no one is at home.

AC Tip #4: Check Condenser Unit Fan

Condenser fanTurn the power off to your air conditioner unit, and check the fan mounted on the top of the outside condenser unit to make sure it’s still in good condition. Replace the fan blades if there are any cracks or chips visible in one or more of the blades.

If you have an older air conditioner unit, the fan motor bearings may need to be oiled regularly as well.

AC Tip #5: Clean Outside Unit

Over time leaves, dirt, grass clippings and the like will build up on the outside of the air conditioner unit, decreasing system capacity and reducing air flow.

After shutting off the power to the unit, use a garden hose to gently wash out the debris, starting at the top with the hose at about a 45° angle. Do NOT use a power washer, and take care not to bend or damage the delicate fins on the coil.

Man trimming shrubs around AC unit.

You should also trim any shrubs or other plants back from around your air conditioner to keep from impeding air flow to and from the unit.

Hot Water Heater Maintenance Tips for Your Home

Performing simple routine maintenance on your water heater can make it last longer and keep small problems from turning into big ones. Check all the pipe connections and valves for leaks once a month. On gas models, be sure the vent pipe is properly installed and there are no obstructions. Every year open the pressure relief valve on top of the tank for a few seconds to be sure hot water comes out of the overflow pipe. Finally, periodically drain a bucket of water from the faucet at the bottom of the water heater to remove any sediment buildup.

How to Save Energy on Hot Water Heaters


Take these steps to save energy and allow your hot water heater to last longer:

  • Insulate any accessible hot water pipes.
  • Turn down the hot water heater to 120° F.
  • Drain a bucket of water from the heater once or twice a year to remove sediment from the tank.

Most homeowners know that regular maintenance is required to keep their home in good working order. But did you know that a lot of this maintenance helps you live a green lifestyle? A good example is a water heater tune up. The newer model water heaters are usually well-insulated, but you should still make sure to insulate any accessible water pipes. This will help prevent heat loss and, as a result, improve energy efficiency. A lot of manufacturers set the temperature in the tank at 140 degrees. Dialing yours down to 120 degrees can cut carbon emissions by an average of 187 pounds per year. Finally, drain a bucket of water from the heater once or twice a year to remove sediment from the tank bottom that could corrode the unit as well as reduce its heating efficiency.
