Standing out in front of the competition through our careful attention to detail, exceptional customer service, clear pricing structure, reliable business operations, commitment to quality, and consistent commitment to you. We are a small local family owned business with 15 years in the Heating and Air-conditioning trade.

"Very pleased. The team arrived on schedule and went right to work removing the old heat pump and air handler. They installed the new Rheem system quickly and were done before 3pm on a very, very hot day. Temperature upstairs exceeded 96 degrees and it was even hotter in the attic crawl space where the air handler was located."

Ballard Mensua Architecture, led by Seth Ballard, NCARB, AIA, is a boutique architecture firm with a focus on creating truly custom designs and solutions for our clients. We have very strong vendor and contractor relationships, a result of our detailed understanding of construction. Unlike many architects, who like to design and then hand over control to the builder, Ballard Mensua maintains control of management of the project throughout construction. We have a unique cost-study process that helps to put our clients in control of spending... and results in completion of projects on budget.. almost unheard of in this business. Our designs speak for themselves... see our website at www.ballardmensua.com. Our business philosophy is that all clients should be a reference and we work hard to make sure to see projects through. We also have a unique ability to do very large projects without tearing a house down... we save much of the house and build around it... saving sometimes 10 dumpsters of landfill (truly green). Finally, where many architects bring their large ego and force their designs on clients... Ballard Mensua prides ourselves on tailoring designs to each client, listening to specific needs and working hard to make sure that our designs fit what a client is looking for.

"We just finished a spectacular custom home project in McLean, VA and we are so very grateful to Seth Ballard and his team! If you are considering hiring his firm, look no further. There can be no better architect in the DC/VA/MD area – and his pricing is more than fair. We first picked Seth because we loved his architectural style and heard that he had a reputation for ensuring that his plans are executed with impeccable precision and attention to quality. Also, his references were stellar….without exception, his former clients offered glowing praise for his talent, diligence, and follow-through. And now that we are former clients, we understand why. We always knew we were going to have a gem of a home with Seth at the helm. What we did not fully appreciate at the beginning was his proven ability to help us STAY ON BUDGET and his deep bench of connections with first-rate contractors and subcontractors who were prepared to bend over backward to meet Seth’s exacting standards. Here are just a few highlights from our experience: CONCEPT PHASE: During the initial meetings at our home, Seth went the extra mile to learn all about our lifestyle, future needs, architectural likes/dislikes, and budget. During this stage of the process, he would effortlessly make freehand drawings to help us visualize potential styles and layouts. We ultimately elected to go with a craftsman design, with lots of wood features inside and out. PICKING THE RIGHT PROPERTY: Seth joined us for car rides through the local neighborhoods, helping us to scout out the property that was best suited for our construction plans – free of any potential HOA or permitting snafus. DESIGN: With Seth’s guidance, we iterated on different design options. The design phase was high-tech and highly visual. Lots of 2D and 3D elevations, plus 360-degree videos. At each step, Seth clearly identified the estimated construction cost, and we would make decisions about what to dial-up and what to dial-down. For example, we elected to go with a cheaper asphalt roof (rather than slate), but with a more premium window. There were literally dozens of choices like that, and Seth did a superb job of helping us to make the right trade-offs and to “value engineer” the house. PICKING THE RIGHT CONTRACTOR AND SUBS: One of the things that distinguishes Seth from the competition is that he works closely with a handful of contractors and subcontractors who have already been “pre-screened” for excellence. Seth connected us with a general contractor who was not only honest and diligent, but whose carpentry was truly “artisan grade.” Seth also drew upon a stable of outstanding subcontractors – in areas such as HVAC/plumbing, electrical/lighting, structural engineering, cabinetry, tile, drywall/paint, countertops, hardwood flooring, landscaping, etc. It was perfectly clear that these subs were striving to deliver the highest quality and exemplary service. Why? Because Seth was an important source of repeat business for them. This made them extremely responsive. BUDGETING: Seth developed detailed spreadsheets estimating costs for every aspect of the project, as well as options for “enhancements.” Once we made our choices, he was instrumental in securing a FLAT FEE CONTRACT with the builder (inclusive of subs) for everything we wanted. To provide even more control over the cost, the agreement specified that certain items would be “owner provided, contractor installed.” This meant that, regardless of whether we bought pricey appliances or tile or flooring, it would have no impact of the builder’s fees. To his credit, Seth’s estimates were quite accurate, and the project stayed on budget. ARCHITECT FEES: We negotiated a flat fee for Seth’s architectural services, and got way more than we bargained for. We had no idea Seth would stay so engaged throughout the project -- micromanaging every detail, and even offering interior design suggestions (e.g., stains and paints, cabinet and window designs, furniture layouts, etc.). It became clear that, regardless of how much we had agreed to pay in fees, Seth was “all in,” and was committed to ensuring that the end result was perfection. To be sure, in any large construction project, there will be some hiccups. But this was yet another area where Seth shined. Rather than being indifferent, or pointing the finger at those who were actually at fault, he would step up to “own the problem” and take charge until the issue was resolved. In one such case, he developed a design tweak that saved us money and produced a more beautiful result in the process. We never had to stress too much, because we knew Seth was 100% engaged and we could trust that the final work product would be a treasure of a home. One final thought. While Seth’s tremendous talent is obviously perfect for large custom projects, we have no doubt that he can deliver outstanding value for smaller home renovations too. When we did kitchen/bath renovations in our prior home, we naively thought that a “design-and-build” firm would deliver the best solution. With the benefit of hindsight, we could have done so much better hiring Seth as the independent architect and separately hiring a builder who would be accountable to the architect. The result would have been better quality construction, a better value, and far less stress. So whether you are about to embark on a modest remodel or getting ready to “dream big” with a new custom home, look no further than Ballard Mensua Architecture."

Energy Efficiency Auditing questions, answered by experts

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Yes, pros suggest units with high EER ratings for energy savings.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.
