If your A/C makes a strange sound, call Sound!

Modern air conditioners are built to be whisper-quiet – so if you notice your AC sounding more like a popcorn maker or a helicopter, it’s typically an early indication that something might be wrong. Time to call Sound Energy to check on your AC system! Our expert technicians will evaluate your system and offer you sound advice on next steps.

If an upgrade is necessary, we sell and install high-quality air conditioning systems from Trane, one of the most trusted names in the industry. https://soundenergycorp.com/air-conditioning/

Conserving energy this spring doesn’t have to cost a lot! In fact, here are three energy-saving tips that’ll cost you nothing at all:
1) Close curtains, drapes, and window shades during the day to keep the sun from heating up your rooms.
2) Cook outdoors on the grill instead of indoors on the stove.
3) Keep furniture and rugs away from air conditioning vents.

Why is a fish talking to you about your heating oil?

Simple. Because right now, you can clearly look through my tank and see me.

Not so with the fuel inside your heating oil tank. Your tank may look terrific from the outside but something fishy may be going on within! Although heating oil tanks are exceptionally safe, there’s always a chance of a fuel release.

My advice? Protect your tank by enrolling in our ProGuard Oil Tank Cleanup and Replacement Program! Read more: https://soundenergycorp.com/tanks/

“March” over to energy conservation!

Energy conservation not only means going green … it means saving green, too! Here are 3 tips to begin with:
• Open windows to let the fresh air in. A good rule of thumb is to open windows when the outside temperature is cooler than the inside of your house.
• Set ceiling fan blades to rotate at higher speeds to create a cool, downdraft breeze.
• As part of your spring cleaning, clean refrigerator coils to extend the life of your fridge.

In addition, Sound Energy’s annual heating system tune-ups and cooling system checks are terrific ways to save energy and money. Comment below and let us know which conservation tips you intend to follow. We’d love to hear from you! https://soundenergycorp.com/
