For window a/c and split a/c units, remove and clean air conditioning filter once per month. For central a/c units, replace your filters once per month.

DAILY – To prevent clogs and bacteria, scrape food from the dishes and pre-rinse before loading them in the dishwasher.
WEEKLY – Be sure to run the dishwasher at least once a week, even if it is empty, to prevent any clogs in the drain line. This is especially important if you have a garbage disposal. 
BEST PRACTICES:
If you are in a property without a water softener, add 2 cups of white distilled vinegar every few months to dissolve hard water deposits
DON’T overload the dishwasher – this will prevent it from cleaning well.
DON’T use liquid dish soap or gel soap – they will over sud or block up the system

Be careful to keep foreign objects from going down the drain. Consider placing removable strainers on each of your kitchen drains – these will easily capture anything that is not supposed to go down the drain and can easily be cleaned. To prevent clogs from hair, food, and oil – Pour 1 Tbs of table salt and 1 Tbs of baking soda down the drain, followed by 1/4 cup of white vinegar. It will start bubbling and fizzing. Wait about 20 minutes and pour in 2 quarts of HOT water. If you are treating Kitchen drains or Garbage Disposals, use COLD water.

During normal use, make sure to use a strong flow of cold water while your disposal is running and for a few seconds after you stop the disposal. Periodically clean your disposal by grinding 1 cup of ice and a few slices of lemon or orange. This will fight odors as well. Put very few things down the disposal – you should scrape pieces of food, etc, into the trash before rinsing the dishes and using the disposal. NEVER put grease or oil down the disposal and do not try to grind bones or pits. Also keep foods with a lot of fibers out of the disposal, including artichokes, banana peels, celery, and corn.

Smoke detectors should be checked regularly. There are many types on the market – check the operation manual for your detector. This info can often be readily found on the internet. Change batteries at least once a year. Most systems will chirp to alert you that the battery is low. If your smoke detector does not work properly after changing the battery, submit a maintenance request.

Don’t flush anything except toilet tissue – things like paper towels, diapers, napkins, sanitary napkins, tampons, balls of hair, Q-tips, and rags will cause problems. Do not use hangers or snakes to unclog a toilet, they may cause damage to the porcelain bowl.
