I run an energy program in the mountains of Colorado. We have a lot of homes without existing duct work and older style wall-mounted furnaces. I've been looking for a decent upgrade choice for my clients - so far Rinnai seems to be the brand of choice for most heating contractors. Problem is they have an AFUE of only .82 at the max, so don't qualify for high-efficiency furnace rebates through our program.
I recently discovered the Energy Saver 90 Plus from Empire Heating, a…Continue
In 2013, Boston earned the title of the most energy-efficient city in the United States from the American Council for an Energy-Efficient Economy (ACEEE). So why is the city outranking all others?
For one, the city implemented its own Climate Change policy, which sets energy-savings goals, such as reducing greenhouse gas emissions 25 percent by 2020, for the municipal government and the community. In 2013,…Continue
In 2013, we published a blueprint with the National Home Performance Council that outlines a seven-step…Continue
With the Google buyout of NEST thermostats, attention has turned from the “smart meter” to the thermostat as a focal point of residential energy efficiency. (Read this recent editorial by Alan Meier.) But several years ago Energy Star decided…Continue
If we want to make good, or great, home performance a reality for more people and families across North America, we must come to some agreement on standard retrofit packages that work. Not every house is the same, but we can agree on standards that can be widely, quickly, and efficiently applied to similar housing types. The home performance community has more than three decades of experience to bear on the question. Please add your voice to the discussion.

Attention Wrightsoft Users!
Have you ever completed a load calculation and it just seems like it was short of what you had expected? Particularly when you are first starting out with a tool, contractors can make mistakes. After all, we tend to learn "the hard way", right? In an effort to make software work, the companies tend to start with some default values that require adjustment. For instance, most have the duct system in…
Here is the offending thermostat. Check out the mercury switch under the dial! Thank goodness we don't make them the way we used to…Continue
Cleaning the condenser coil. This has always been the number one task that Service Technicians avoid at all costs when maintaining residential equipment. Maybe it is the nature of the fast paced business when the weather gets hot? Certainly could not be the lack of water to rinse the coil as there is almost always is a water spigot on either side of the home. I cannot figure out why, and this may be one of the largest aspects of seasonal maintenance that impacts the efficiency of…Continue

This is a sales tactic often taken by a used car salesman. A Quality HVAC Contractor will price their installation with confidence, after finding a solution to fit the needs of the customer, and correctly sizing such equipment. I have no problem with "ballpark" numbers over the phone, as this can help sift through customers that are not interested in quality, so contractors do not waste time on what tends to be free…

I worked as a janitor at St. Camillus elementary school after school and in the summers when I was in high school. I enjoyed the camaraderie with the other high school kids I worked with, and the crusty Dutch man who was our boss. We cleaned every afternoon in the school year and on weekends, and then painted, cut the grass, and did maintenance on the heating system and other equipment in the summer. We took pride in our work, but we also had fun—once in a while playing a game…
Remember, though, improvements must have been installed in 2013, not just purchased, and generally, claims can only be made on your primary residence.
Eligible measures may include doors, windows, and…Continue

There’s my thermostat now, a squared-off plain looking fellow named White Rogers. He hangs over my shoulder and mocks me three or four times a day for not being smart enough, or responsible enough, to program him. "Hey! I’m BUSY HERE, TRYING TO TRANSFORM THE MARKET FOR ENERGY EFFICIENCY, and you, Mr. White Rogers, are a daily pain in my side. I can’t read you. You don’t even know what time it is, but I do, it's time you get dumped! I’m going over to the Apple store to pick up my own personal…Continue
We've created a blog post at AlabamaWISE.com comparing home energy efficiency to auto energy efficiency over time, using photos to help people visualize the prevailing technology when homes were built: http://www.alabamawise.org/whats-your-home-mpg-rating/
Vital to the operation of the refrigeration cycle, superheat must be maintained and stable to protect the compressor. We all know that the heart of the system cannot compress liquid (slug) without bad things happening. This would represent low/no superheat. But, did you know high superheat can cause valve and compressor problems as well? No matter the reason for attaching your gauges to the system, you must check the superheat, in the air-conditioning cycle.…Continue
I was reviewing an article in Home Energy by Steve Mann that came out in the January/February issue (“DOE’s Challenge Home,” p. 6). He wrote on the latest iteration of DOE’s Challenge Home Program. Steve points out, in his usual insightful and articulate way, what he sees as the strengths and weakness of this program. I hope you’ve read it, or will read it. Send us your comments by email, or on the Home Energy website.
Reading Steve’s article made me think, “Wow, do…Continue
The January/February 2014 issue of Home Energy magazine officially kicks off our 30th year in print. In commemoration of our 30 years we will be reprinting some of our earliest articles. We hope that these articles are both entertaining and informative.

It seems like every one and their brother has a Night Before Christmas parody. Mine appeared in fragments on Twitter a short while ago, during an odd moment of creative inspiration, and would’ve been completely lost to Twistory, had it not been for my good friend Sean Lintow Sr.…Continue
Twas the night before Christmas, when all through the house
Not a cool draft was freezing, to wake up the mouse.
The owner called a contractor with knowledge so rare,
In hopes that great comfort soon would be there.
The children were nestled all snug in their bed,
With nary a cough or a cold in their heads.
And Momma in her Kerchief and I in my cap
Had just settled down for a long winters nap.
When from my neighbor there a rose such a…Continue
