Freeze Ups

ACs tend to freeze up during the peak heat of the summer months, and it can be bizarre to see your air conditioner frozen with the summer heat beating down on it.

Does your sink stink? It might be the garbage disposal!

Garbage disposals are designed to pulverize and remove food waste. Without regular cleaning, trapped food particles can cause mold and bacteria to grow, making the air in your kitchen unhealthy – and stinky! Your drains can also become clogged with grease, adding to the problem. Here’s how to prevent grease and bacteria from building up in your disposal and drainpipe.

Water Saving Tips for the Homeowner

Did you know that you pay twice for every drop of water you use? You pay for the water when it comes out of the faucet. If you’re connected to a public sewer system, you pay a sewage charge when it goes down the drain (along with more of your money).
