What you need to know about Going Green?


EAI Climate Zone Map

Did you know that Tennessee ranks 4th in the nation for residential energy consumption? This is according to the U.S. Energy Information Administration.

Did you know that space heating and cooling accounts for 48% of the energy consumed in USA homes.

Accordingly the Nashville area  presents major opportunities for Going Green.  This is a subject we talk about a lot and over the next few months we will address some of the ways to save energy in homes, offices, retail stores, schools and factories.  This is a very complex subject with many different approaches. Your HVAC systems are major energy users in the home but there are many other energy users including water heating, lighting and appliances. 

The area of the country in which you live and work has a major impact on energy consumption.  The US Energy Information Administration (EIA) provides a vast amount of statistics including the climate zone map showing that Tennessee is in the Mixed-Humid zone.  Our zone could well be the highest energy consumer from a heating and cooling point of view because we have hot summers, just as hot as the deep south, and winters just about as cold as much of the northern regions.  Up north they don’t have the hot summers, so air conditioning use is lower than Nashville, and down south they don’t have the cold winters so their heating bills are less than Nashville.  For example EIA stats show natural gas consumption per household in Nashville is 2.85 times what Florida household’s use.  Surprisingly Nashville households use the same amount of natural gas as New Hampshire homes.  

There are many approaches to energy saving.  Some save electrical energy, some save energy from natural gas, and some save both.  Programmable thermostats can save electrical and gas energy as does increasing insulation and fixing leaking ducts in unheated spaces.   Some new power conditioning systems save the electrical energy consumed by the compressor and blower motors in your HVAC. I will be writing more about these topics in the weeks to com.

What you need to know about Mini-splits.


Cassette Inside Unit

Mini-split is a nickname for small HVAC systems with the condenser outside, and an inside unit mounted to a wall or ceiling. The inside unit is a substitute for a typical air handler. The inside unit is called a cassette and they range from three to four feet in length. The cassette distributes the cool or heated air in the space.  

No ducts are required and only small diameter lines are needed to connect the outside unit to the cassette.  In a home the space is usually going to be a recreation room, a basement room, an attic room, or a big large room that needs heating and cooling.  Mini-splits do a wonderful job of spot heating and cooling.  In the past window units or through the wall hotel/motel units were used. These were noisy and inefficient.   

Outside UnitThe mini-split works much better. They are quiet (because the compressor is outside) and very efficient with 16-18 SEER ratings or even higher.  The main feature is they deliver point heating and cooling very accurately.  A commercial example of a mini-split system used in a small rural store is shown in the two photos.

As far as brand we use Mitsubishi units a lot. They have an impressive 7 year Warranty on the compressor and 5 years on the other parts.  However if you can’t get parts it doesn’t matter how long the warranty is.  In our experience Mitsubishi and Samsung make it easy to get parts in an expedited manner.
