"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

"We had a great experience with Bethesda Systems. Jay came out to our house shortly after we requested a quote, asked what we were looking for, thoroughly investigated how to install what we needed, and then provided a detailed quote that gave us options of what speakers we could choose from and where to install them. The quote covered three areas and we ultimately chose just to install outdoor speakers. The actual installation process was done professionally and expertly with minimal hassle for us, but with a complete explanation of how to use Sonos. All in all, we are very happy customers and would use Bethesda Systems again."

"Avoid at all cost. Don't even get HomeServe home warranty cuz that's what they use. They came and fixed the leak by replacing the toilet ring/rubber. During the process, they caused a leak between the toilet tank and toilet bowl and refused to take responsibility saying they didn't touch the toilet tank. They actually did. I watched them when they used a water suction vaccuum to get dry out the tank. Also they had to unscrew the bolts connecting the tank and the toilet seat. When putting those bolts back they didn't do it right and the leak is where the bolts connecting them. Yet they said they didn't touch it. Wow. We are currently looking at actions (perhaps a small court claim) that we can take against them. Just found I can file a complaint on Department of Professional and Occupational Regulation which is where all the licenses are granted. Perhaps contact City rep too. Im going to wait and see if this gets resolved first."

KCS Heating & Air
KCS Heating & Air
We are an 8(a) woman owned business with over 20 years of experience in the Northern, VA area. Licensed, Bonded and we have a Certified Class A Masters Contractors License. Our company was raised by our commitment and dedication to our customers. We were founded on the premise that there is a cheaper, more efficient and environmentally conscience way to improve heating and air-conditioning use down to a precise proficiency no matter the size of the home or the budget of the homeowner.
"Guys. If you've found yourself without heating or A/C, these are the people to go with. We have used them for a couple years now, with most calls for help starting out panicked because the unit was old and always chose to go out right before a heat wave, when we had out of town guests, or when we had a newborn. We've had the pleasure of working with most all of their employees now, and we can't say enough good things. They are friendly, professional, knowledgeable, and respectfully mindful that they are working in someone else's home. Most recently, our HVAC finally failed completely and we had to replace the whole unit. Lindsay, Neal, and Matt were gracious as they dealt with our questions and initial sticker shock so we were comfortable investing as we selected the right replacement for our home. We quickly got on the books and Kieren and Carlos came out to replace the unit. They got the entire thing done in a day, even when a severe storm came through and limited their ability to work outside. They were quiet, efficient, and cleaned up beautifully after themselves. Plus, it was the first day of a record heat wave so we were extremely relieved when the house had cooled 5 degrees in less than an hour! We highly recommend this company, from a family who's experienced them across a spectrum of needs: from checkups, to minor repairs, to major repairs, to complete replacement."

FAQs for energy efficiency auditing projects in White Post, VA
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
