"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!"

"My husband and I had a wonderful experience. We initially found this company when searching online for information about energy audits and saving money on our utility bills. We were not sure what all was involved with this but the representative that came out was very knowledgeable and explained every detail. The audit or energy loss inspection showed us why we had uncomfortable rooms and why our energy bills are high, especially peak of Summer or Winter. We had no idea. We learned a lot about our 14 year old home that we never knew as well as a product that we purchased for our attic that reflects heat away. So far, we have already noticed a drop in temperature overall in our home and certainly in the rooms we were worried most about. Our energy bill this month was the lowest it has ever been in the Summer. We are thrilled with these results and everyone we met with this company. 0"

"We met with 3 different companies to advise on getting solar panels. The first 2 companies basically just told us what size system we could get based on state and federal tax rebate levels. Heard an advertisement for Sunpro on radio and decided to call them; turned out to be a good decision. Kara with Sunpro was extremely informative and had a nice package put together for us to review. She even researched our home and had an idea of how much production we could expect with the recommended solar panels. Even after selecting Sunpro, I called Kara with questions about things I'd heard from others or something I forgot to ask. I never felt like I was a burden and she always returned my calls if I had to leave a message. The complete team with Sunoro were professional and eager to help. Satisfied with new solar system and looking forward to enjoying savings on electric bills.

Energy Efficiency Auditing FAQs, answered by experts

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.
