"This appointment was the free maintenance checkup following the installation in June 2014.  Scott H was my Service Technician.  He was very professional, arriving on time; explaining what he will check during this appointment; explaining his findings; making sure I scheduled my next maintenance checkup, also, making sure I had signed up for the Maintenance Agreement. Additionally, Scott H connected me to Christie in the Alpine Office to make sure they knew that I am an Angie's List member. He was very pleasant and comforting to talk to making sure I understood my system. He also made sure he covered his shoes when entering my home. I give Alpine an "A" rating."

"Ecomaster did an excellent job putting in the insulation. They sealed the attic, put in blown in insulation, plus weather striped and sealed stairway . They made an error in what to charge us- the attic space was larger than the house diagram showed. So, they actually charged us less than they should have. But they held to original estimate and didn't charge us more. I appreciated their honesty and integrity in keeping their word and holding to the original contract. There was also a rebate from Duke Energy that we were supposed to receive for putting in the insulation. It took 6 months and a lot of follow up on their side but they kept at it, kept us up to date and we finally received the rebate. I am very grateful for the work they put in after the sale. Our energy bills have dropped dramatically since the insulation was installed."

"We had been
looking for a state of the art solar power system, using the latest technology in
solar and battery backup.

It was hard
finding a company that could stabiles power in our home and give us what we
wanted.  The power from the local power
company was always over high voltage or very low shorting the life of my electronics
and motors in my home and workshop.    It
was hard finding a company that knew what they was doing and giving a good
price for what we wanted. The Company Renewable Engineered Systems RESllc  was the only one that was able to do this.           Only 1 volt flux of voltage  There system acts like a cpasator in my home
and give us very clean power this will extend the life of all my electronics
and motors that i have in my freezers and fringes and well pump.

This works day to day plus if the grid goes
down, my house will still be running with solar power"

"good recommendations- not overly done
solutions made sense -
E2 's price to do work seamed a little high
did not do waterproofing at this time due to install of solar panels
will consider for later work.
 
Evaluation was result of talking with company at home show.

"Scheduled an appt., requesting a quote. He showed up on time, inspect what needed to be done. He said he would call us to give his quote, but we never heard back from him. if we did not hire the other HVAC company, my husband and I would definitely consider using E&J Heating and Cooling to do the job."

"Our serviceman Derrick did a wonderful job of troubleshooting our system and taking the time to explain what problem he found and how what steps we need to take to fix our issue. Overall, he was very professional, thorough, and polite. We would trust to have Derrick work on our heating system again."

"We are pleased to recommend Triangle Reconstruction with our highest praise. It seems too simple to say that they do what they said they’d do, but that’s exactly what happened. Our home is around 50 years old. Ours was a large job - around a month and $30,000. We had Triangle Reconstruction come in after another moisture company provided mold remediation and a humidifier. I wish we’d contacted TR to start with. We provided TR with a structural engineering report. They created a plan to exactly meet all of engineer’s concerns. TR used temporary supports and replaced seal plates, girders, and joists for over half of our home. In addition, they poured footers and built new columns. They also added a few additional girders to firm up our floors. They removed and replaced our insulation. They sealed our porch and crawl space, replaced our vapor barrier, and installed a moisture meter. They wrapped our electrical cords and hung them. The people at TR are remarkable. A+++++"

"Don and his asst. cleaned up, took the torn down fence away, and left me very satisfied with the outcome. I will use Hammer Handyman in the future and already have an estimate for another job. I really like that I was charged only for actual time and materials and not simply the estimated cost. I will recommend him to friends and coworkers."

FAQs for home energy audit projects in Sanford, NC

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
