ECS is a top-rated Georgia Power contractor, and part of our service is to ensure that our clients get maximum rebates available to maximize return on investment. Our recommendations are very specific to our client's specific needs. ECS files all rebate paperwork to ensure our clients receive their rebate checks in a timely fashion.

"ECS performed an energy audit on my home and identified multiple ways to improve the energy efficiency. Shane and Cole did a great job explaining the options and helping me choose the ones that would make the biggest impact. The result was a 36% reduction in air leakage. They also helped get rebates from Georgia Power. I highly recommend their services!"

We love helping families go solar. We work with several installers to get you up and going quickly with the best finance options. Stop talking to sales guys and door knockers who only want to take advantage of your lack of knowledge just to line their pockets with inflated commissions. We get you installed on average in about 45 days or less. If you want to learn the truth about solar, how it works, and how much you can save we are willing to help. Let's walk through your power bill and break down all the charges to see exactly where your hard-earned money is going. Renting energy is a waste of money. You already own your car, and your home, It's time you own your energy!

Bester HVAC is proud to offer my customers easy apply financing through Hearth. Hello this is Kwame from Bester HVAC. We are a small family owned business and have been in business for 5 years. We focus on making sure you the customer get your issues diagnosed quickly and professional. We strive to make sure our customers have every bit of information so can make an informed decision. We also pride ourselves on having integrity, honesty, and we are trustworthy. We will tell you exactly what's needed to have your system running or to have it replaced. Due to Covid 19 we are limiting contact. With that being said I can usually quote a system replacement from either a picture of the labels or a system size, type, air handler/furnace location and city location. We will get you the best price on goodman, smart-comfort/carrier, or Payne equipment. We also do not require an upfront payment for equipment deposits. We operate off of trusting our customers from the beginning. Trust is earned and we believe that we will show the first sign of trust by taking your word for gold. I personally have been in HVAC for over 15 years and I have experience in all types of systems and home setups. From split levels, ranch style, apartment/condo, or traditional homes. I also am a former Apartment Maintenance Supervisor as well so we do it all from single family homes to multifamily homes as well. Payments Accepted are credit/debit cards, as well as a plethora of digital payments. All of my quotes are good for 1 calendar year. The price I quote you will be flat rate + 8% sales tax. We are based locally in powder springs GA but we travel up to 100 mile radius so don't hesitate to reach out to us. We usually can beat any written quote by at least 15%. If you need help don't stress call the Best. Kwame Bester Bester HVAC 225-603-3070

"The initial meet up was ok. He came and setup the AC system while I was at work. My 1st mistake. When I came home I discovered he input the wrong size system than what we agreed to. He also went into the attic and did not say that the system he just installed was not compatible with the unit I have in my home. I don't mind paying money if it is needed, but now he will not answer to correct his mistakes. Do not go to this company. They are not reliable and they will be stealing your money. Now I have to pay some else to replace the entire system. Not worth my time or energy."

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.
