LED Lighting - Garage Door opener interference

Background

In November 2012 I started replacing all CFL and Incandescent lighting in the home with new LED bulbs. At our local 'big box' home improvement store I purchased several (35) LED bulbs and began making the switch to LEDs. Over the past several years most of our incandescent lights had been replaced with CFLs. I was not happy with the performance of the CFLs both in terms of light quality and life of the bulb. It seems like every other month I was…

A Successful Technician

I am sure I am not the first to write about this, but it doesn't change expectations of homeowners or trade employers.  Why is it that millionaire ball players can be successful batting .300?  A pitcher can have thirty starts, win 20 games and could be named for the Cy Young?  Or that a successful quarterback can throw 20 touchdowns and 10 interceptions?  The reason: they are much better than their peers.

     Imagine, as an HVAC Tech, you got the diagnosis correct  one-third of the…

Energy efficiency and a cold marriage

We know energy efficiency can save the world, but can it save a marriage?

Leave it to the New York State Energy Research and Development Authority (NYSERDA) to take on that question. The agency is known for its vanguard energy research.  But it is one thing to produce papers on topics like ‘Air Bypass in Vertical Stack Water Source Heat Pumps’ and another to delve into what a cold room can do to a new marriage.

That’s  the premise behind Irreconcilable Temperatures,  a…

Storytelling from BECC

When I attend a conference I can always tell which sessions I find most inspirational by the amount of notes I take. While attending the annual Behavior Energy and Climate Change (BECC) conference on Monday of this past week in Sacramento, the note test proved itself once again. Hands down, I found the most inspiration from the afternoon Spotlight Panel titled “Hollywood, Media and Messaging.”

To be fair, I was excited about…

Return Air Locations

     When using ACCA's Manual T for register selection, there are several basic rules that are followed regarding location. Most guidelines revolve around room air circulation and stagnant air, as well as the equipment application (heating only, cooling only, or combination). Application is the largest determining factor when it comes to return air locations.

      For heating only applications, a low return duct is ideal to bring back the coldest air otherwise stagnant in the room.…
