"From the very beginning, this company has been responsive, punctual, and communicated very well. The owner came out to evaluate our home system and problem with" upstairs being hot. He answered all my questions and gave me very practical and honest answers. We proceeded to start the process to replace our units. They make their recommendation on which systems to install based on testing, which I was happy to hear after everything I read. After lots more questions, we made the decision to proceed with the installation. Their office is very professional. They were responsive to answer my questions. The actual installation went smoothly. They were very professional. Cleaned up after the job. Gave excellent practical advise afterwards. Overall, I was very happy with their company, and I plan to use them for future jobs and projects.

"A detailed report was given and it included a list of all areas of concern for energy efficiency. It was then given to contractors to bid on the desired services.we wanted done.

Home Energy Audits

One thing homeowners can do to save on energy costs is to have a home energy audit conducted. This will reveal where drafts are entering from outdoors and where insulation is ineffective. Energy auditors can also recommend upgrades in appliances to save energy.

After I contacted them they sent out a technician to test the air leakage the house. This requires closing all windows and doors except the front door. They install a frame in the door covered with plastic except for circular opening in which they put in a blower
The fan is switched on this causes the house to be pressurized. The tech records the reading. He tells me the result is not terrible but far from ideal.
The next person sent out from the

was a very knowledgeable gentleman named

Eisenbraum. We went around the house and he showed me all the places I was losing heat or a/c. We than sat down discuss the work to be done and gave me a price. The estimate was fair considering all the work that had to be done. I gave him the okay and we agreed on a start date.
I was very happy with the crew. They arrived on time were polite, friendly, respectfull since they were all through my house and cleaned up nicely afterwards.
In conclusion I am very happy with the results. My air leakage test passed with flying colors. My ceiling is no longer very warm to the touch, My through the wall A/C actually goes off on hot days. I can shut the A/C off leave the house and come back hours later and still be a little cool (never happend before). I suspect my heating bill will be alot less this winter.
I sorry I didn't do this years ago

Very nice and professional provider. Made a complete list of items needed and included suggestions for cost saving things to do. I will be having them back in the near future to do some of the suggested items. Overall I was very happy with them and feel my money was well spent. I look forward to making those changes to improve efficiency and save money on heating and cooling costs.
- Ken T.

Excellent, professional, willing to work in my budget. Called when he was on his way. Went through the entire project and discussed my needs with me when he first arrived. Would definitely recommendand would use again.
- Margaret W.

We not taken advantage of the insulation offer because the visit by the representative was primarily a sales job. We were not interested in having a lot of work done, primarily because of the possibility of Georgia 400 and

expansion. The representative did not do any sort of air leakage test, which was part of the offer.
- Ryan M.

The guys were friendly. They installed both attic fans on the roof within just a few hours while a different crew installed the radiant

foil. Both were done within a day.
I also opted to have spray foam insulation added in one wall that faces the afternoon sun. There were a few snags with that part of the job due to equipment problems, several delays, and somewhat of an insulation mess...but in the end it was fine. Overall I am happy with this company.
- Eileen P.

I have mixed reviews. He came out. He was punctual. He was pleasant. He was good with what he did on site. He was supposed to send a follow-up on green energy assessment. The weatherstripping that he installed very quickly started to degrade and is now coming off. The price was fine.
- Steve S.

We moved into a "new" house that only had a few inches of nasty insulation in the attic; the heating and cooling bills were very high. We had

give us an estimate that was lower than some of the well-known competitors in our area so we went with them. They did a fantastic job, answered all of our questions, and cleaned up very well after the job was done. We also had no trouble passing the TVA energy right inspection once they were done. Our electric and gas bills are significantly lower now, too! I would use them again in a heartbeat.
