The #1 Item Missing from High-Efficient HVAC Installations

     Imagine this: you go out to your local entertainment big-box store and purchase the top of the line “HUMONGOUS” television.  When you get home, you don’t think anything about it and just go ahead plugging it directly into the wall socket, right?  What’s that you say, ludicrous?  Of course, we would only plug that piece of beautiful technology into a UL rated surge protector!     So, I gave it away in the first paragraph: a UL rated surge protector.  But, don’t you want to know why?  Or…See More

How Low Should I Operate my Heat Pump?

UPDATED: Break Even COP’s for MAHow do you know if you should install a ductless mini-split, or upgrade your air-conditioner to a heat-pump and create a dual-source application during replacement this Winter?  I have been asked this countless times over the past week!  I personally always prefer the option of multiple fuel sources, particularly since energy prices have been all over the place during the last decade.  Fortunately, using averaged energy prices, there is some simple math to figure…See More

"Peak energy use is a summer issue. TOU rates apply. Located in OKC. That's why I mentioned local rates structures vary A LOT."

Christopher Morin commented on Christopher Morin's blog post How Low Should I Operate my Heat Pump?
"Great points Bob!  Can I ask where you are located?  Here in MA, our utility providers have a tiered structure to charge more when using more...I guess it depends on when, or even if, you have a peak demand problem in your locale.…"

Bob Blanchette commented on Christopher Morin's blog post How Low Should I Operate my Heat Pump?

Should this Duct Layout be Banned?

When is it ok to put your ducts into an attic, tight up against the Roof Deck?  With more conventional building techniques, I would have to argue: NEVER!  I do not care how the homeonwer pleads to keep their storage space, you cannot count on delivering cool air to the conditioned space with said branch duct.  Even if you did figure out a way to secure the duct to the peak without crushing the inside diameter, the CFM is not the problem.  The real issue becomes the dry bulb temperature of the…See More
