Solar photovoltaic panels capture the sun’s ultraviolet energy and convert it into electricity. Unfortunately that energy is in DC current and your home runs on AC current, so the power has to be inverted from DC to AC.We have two primary ways to invert the power. The first is by combining all of the panels into one system and having one large inverter that handles the entire array. The second is having a small micro-inverter on each panel and inverting each one individually.We prefer the micro-inverter method because in most cases it is more efficient. The problem with a central inverter is they work based on the lowest common denominator meaning all power output is based on the lowest producing panel so if you have 20 panels and you shade just 1 the other 19 lower their output to the lowest level.

Here at the Clark household we recently had a debate about running the kitchen exhaust fan while cooking. Chef Haley (my wife) hates the sound of the fan so she prefers not to run it. But the smell of the gas range burning has me concerned about carbon monoxide poisoning.We have a carbon monoxide (CO) alarm that never goes off, so you might ask why I’m concerned. Here’s why: The CO alarm was not good enough quality for me to be 100 percent satisfied we weren’t getting low-level CO exposure. CO alarms only detect sudden and deadly levels of CO, not low and ongoing levels that create significant health risks in a home.

Many of our construction techniques have evolved by necessity due to how we live in our buildings. A great example of this is that 150 years ago in the warm South we started building elevated homes. This kept the house cool by allowing air to move underneath. We also began using high ceilings to allow the hotter air indoors to rise above the living space and constructed big wrap-around porches to shade the windows and keep direct sunlight out. All these changes helped create the Southern-style home most of us know and love.

Home energy efficiency is problematic when you have a ventilated crawlspace. Cold air blows in from the crawlspace and hot air rises, leaking through all your attic penetrations. Your home becomes a virtual chimney and loses all your precious conditioned air through the attic leaks. This means your heating and cooling systems have to run harder to keep up. At the same time, contaminated air from the crawlspace are circulated in your actual living space.

There is a catchy phrase right now that is growing in popularity among top builders: “Build it tight and vent it right!” We really need to change the conventional wisdom of ventilating houses. Vented crawlspaces are a very bad thing. Most good builders have switched to sealed, insulated, conditioned crawls…but that is just the beginning.When it comes to home construction, there really is no such thing as too tight. We want our homes to be airtight, then we bring in the right amount of fresh air through intentional ventilation rather than unintentional infiltration (air coming in through uncontrolled places like leaks in the crawlspace). We also want to control exhaust ventilation such as bath fans, range vents, and other exhaust when needed (i.e., radon control fans). The incoming fresh air and the outgoing exhaust air should be balanced.

Maintaining your home’s heating system is a big responsibility for any Lexington area homeowner, but few people actually take the time to schedule routine maintenance to make sure their systems are running smoothly year-round. Without routine heating maintenance, your home’s system may run less efficiently, which means it also runs the risk of breaking down and racking up larger utility bills. Synergy Home is here to help! With our easy and cost-effective HVAC maintenance, we’ll keep your system running efficiently 24/7!

If you have read anything I have ever written, you know by now that I preach about the “domino effect” that’s created when we make one upgrade to a home without accounting for how it affects other systems. Case in point: I recently visited a client in the Lexington area who said they had a case of “sick house syndrome,” meaning their house was making them sick. They would travel away for a few days and feel better, but immediately upon return, symptoms would reappear. There was also an off-putting odor in their home that they could not eliminate or identify that was making everyday living unpleasant.
