I am located in NW Florida, Six years ago I transitioned my HVAC company into a Home Performance Contracting company specializing in HVAC, Insulation/Air sealing. We have certifications and licenses through BPI, Resnet Rater, Home Inspector and Mold Remediator etc… I have differentiated my company from the many other HVAC contractors by offering more efficient installations through our innovative use of an integrated, whole- house as a system approach to performance and energy efficiency. Our methodology allows us to go beyond the usual HVAC and specialty contractor guesswork and quickly and accurately solve a home’s comfort and energy efficiency issues. With that said I just received a letter from our utility company offering training on the CheckMe! Plus program, in your opinion how is this going to affect our positioning. I guess my concerns are that this training will in effect level the field from the customer’s perspective.

Hello: Regarding MikeK's comments on the UC Davis "Night Breeze", thought I'd weigh in with a description of my "poor mans version" of their system. We live in the high desert of Carson City, where cooling season temps may cycle between 110 and 60. Five years ago, I framed an inexpensive, 2200cfm, 20" box fan into the attic hatch of our 1750 sq ft., 2002 home. About 1AM, the timer I also installed turns the fan on and by morning our interior temp is within 10 degrees of ambient (relief air from two open windows). To coast through the recent 100+ days, I have had to run the AC briefly in the morning (cool attic and vents and optimal ambient for condenser operation) to bring the house to down to 68. Late evening temps may approach 84, but with minimal humidity it's not a problem. Currently looking at a 3220 cfm fan (Lasko 3720) to move more air. Similar homes are spending $250/mo for cooling...we're @ $90.

Another interesting option, developed at UC Davis, is a system called the "Night Breeze". It has a motorized damper in the air return that can switch between conventional operation, and operation more similar to a whole-house fan.

In climates where it can be quite warm during the day, but cools off at night (much of the Bay Area, for example), the Night Breeze is supposedly more efficient. (I have an HVAC company looking into installing one for me…)

What it does is to check the outdoor temperature when cooling is called for. If it's cool outside but warm in the house, the damper is moved so that the warm air from inside is simply exhausted through a gable vent, and cool outside air is drawn in through a filter. The compressor doesn't run at all in this mode.

If it's too warm outside for the system to use outside air, then the damper closes and the system works like a normal A/C unit (although it does periodically open the damper for short intervals to allow fresh air into the house).

I love the idea of this system, because it has the benefits of a whole-house fan, without the hassle of manually opening windows, and without the intake of dust and allergens that are a problem for some people. It's fully automated, which in my experience is the best recipe for consistent use.

I'm ready for a consult from somebody on this in my L.A. home. Can someone suggest somebody? That was mentioned on the show. I can't afford a regular AC install (scoped this out last year) but would like very much to get alternatives/low cost suggestions.

By the way, I do what the last person said – closing the house during the day and opening up at night and indeed, that plus ceiling fans, have kept my home pretty comfortable. Also, I put new coating on roof of the silver stuff.

Great report. Thanks for it!

Other resources in L.A. area that are good to talk to about this – Ed Begley. It's important to many of us in the LA area, at least, to make sure we consider the entire environment re this.

High efficient air conditioning is now readily available from almost any dealer. With the new economic stimulus bill there are some huge tax credits available for homeowners to upgrade their systems. Now is the time to improve efficiency and save the planet.
