Protected: Air Sealing

Air leakage is a major problem in homes. In addition to representing 5%-40% of indoor conditioning costs, air leakage can create comfort and moisture problems, as well as introduce pollutants such as pollen, dust, and mold into the living space. To effectively reduce...

Protected: Insulation

Insulation keeps your home warm in the winter and cool in the summer. There are several common types of insulation- fiberglass (in both batt and blown forms), cellulose, rigid foam board, and spray foam. Reflective insulation (or radiant barrier) is another insulating...

Protected: HVAC Performance

HVAC When talking about HVAC Perfomance, there are two main we want you to think about; The Mechanical System and The Duct System. The Mechanical System The first is the mechanical system. The motor, the coil, the drainage line, etc.. These are the things that come to...

Radon is Deadly

We’ve run across a string of Radon issues in homes lately and the danger factor can not be over emphasized. This stuff is deadly. What makes it so dangerous is that you don’t even realize that you’re being poisoned. In the Gainesville and...

Is adding insulation really worth it?

Short answer: Generally Yes Not so short answer: We think of Insulation as a passive home energy efficiency measure. Passive measures are improvements that help prevent the home from gaining or losing heat. These measures (insulation and air sealing) do not require...

Shaky Suction

A few days ago, I was testing this furnace. The homeowner had some duct work done so we checked the systems performance with an airflow test and static pressure readings. I was in the middle of checking the static pressure readings when I noticed  a small movement out...

Very common, but VERY dangerous.

Here’s something we see all too often during our energy audits around the greater Atlanta area.. A contractor has installed a flexible pipe on the natural gas line. In and of itself that is not an issue. Flexible gas lines are acceptable as long as it’s...

What are barnacles doing in this HVAC system?

Yeah, I said barnacles.  After closer inspection, it was a dust buildup of epic proportions that resembled something scraped off the bottom of a boat. We know that even a slight dust buildup on a blower or coil can have a negative impact on billing and comfort. Our...

Too cool for school

It seems that LaGrange College Mathematics Department has kicked off a new program centered around “affordable and sustainable housing”. Jon Ernstberger, one of the professors, arranged for HDS Columbus to perform an energy audit at one of the older homes...
