I have found that this topic often goes unnoticed, or can be a guessing game out there in the field. Diagnosing improper fixed orifice sizes is actually a fairly simple, cut and dry procedure. First, I would argue for efficiency reasons, as well as ease of proper charging, you should just field install a TXV. Of course, when you are on the job site you don't want to spend precious time attempting to adjust refrigerant charge with the incorrect orifice. You would never be able to get…Continue
In order to feel comfortable in the cooling season conditioned air has to be at the right air temperature AND relative humidity. Conventional AC dehumidifies when it is running but it is thermostatically controlled by air temperature only. Which means that when air temperature is reached the AC turns off and stops dehumidifying. Not a big problem if you live in an arid climate such as Pheonix but if you live in New England where the summers are very humid and not…Continue
At the most recent National Weatherization Training Conference that took place in New Orleans, Louisiana, six people were presented with a 2011 Weatherization Assistance Program National Recognition Award.
The Recognition Awards acknowledge outstanding contributions that advance the goals of WAP through individual or group achievement, inspiration, or innovation. The Recognition Awards program is open…Continue

If the home performance industry had an online dating profile, it would likely be looking for someone with a great network of friends that he could get to know. Home performance would also be looking for someone with a rich history (like himself), good looks that go beyond the surface, and someone who may be able to get some of his friends a job (hey, not everything in a relationship is about romance). Someone like the real estate market, for example. Unfortunately for home performance’s…Continue

Los Angeles is a prime area for solar power, and its development space is growing. More than 12,000 acres are available on rooftops across the city, which could net families and business owners up to five gigawatts of power. This clean energy reduces oil dependency, helps the environment, and over time cuts energy costs. This broad new opportunity provides the perfect time for solar training.…Continue

I don't know how many times a technician has said that they installed a part based on what was on their service truck. I have heard of technicians wasting money over-sizing contactors, cutting down air filters, and even using controlled substances to clear condensate drains! Of course, these scenarios all get the job done, but I would argue the many reasons why not to do these. The one thing that gets to me is when a technician doesn't verify they are installing the correct size dual run…Continue
It's time to turn to cooling thoughts, even though Maine didn't actually get a winter this year. It's true; we had an…Continue

With the modern innovations made possible through technological breakthroughs, now occurring almost daily, many are becoming increasingly concerned with the negative impact these modern conveniences have on our environment. Never has there been a higher demand for individuals who have gone through solar panels sales training and possess NABCEP Certification.
Most people, when posed with the question of how they can make a positive difference on the environment, are sure to mention…

How many times as a technician have you gone out to the same customer's home because of unrealistic expectations? Some homeowners expect air-conditioners to work like an ice box, want you to size them for their big party on Fourth of July weekend, and expect you to show up at the drop of a dime when it doesn't meet their impossible notion. Of course, this could be avoided by establishing a standard during the sales process or a little customer education. I liked to talk about "The…Continue
Just decades ago, solar power was an idea that had not yet reached its time. However, that has changed dramatically as the global community seeks alternative sources of power. The demand for solar energy rose 40% in just one year alone, making this renewable resource one of the fastest growing industries. The earning potential of businesses involving solar power could be astounding in the near future. Individuals qualified in the industry will no doubt have the advantage over their…Continue

An industry's health is sometimes measured by the enthusiasm of its trade shows. Arguably, ACI is not a trade show, but it certainly is a bellwether for the home performance industry. And it rocked. By all measures, ACI was larger, broader, and more exciting than past conferences.
ACI continues to be a magnet for audiences ranging from contractors just starting out and receiving blower door training to engineers and building scientists. In this way, it serves as the premier…Continue
Energy Efficiency Ratio, or EER, is a way to exhibit how well an air-conditioner is operating based on the power being used. Most homeowners are of course familiar with SEER, the ratio across an entire season. Since SEER is tested at a "partial load", the EER is a more realistic number to use when figuring energy savings. AHRI tests their EER of residential air-conditioners using 400 CFM per ton of airflow at 95F Outdoors / 80F Indoors and 67F Wet Bulb. This compared to the SEER testing…Continue
However, it appears that these two companies aren't the only ones trying to get in on the electric car market; it was recently reported that Hyundai Heavy and Magna-E Car Systems have come together under an agreement to develop next-gen lithium ion batteries. Their goals reach far and wide, as Hyundai hopes to have 30% of the electric car market in Europe and North America at some point or another.
With this many car-makers trying to make their way into the electric car industry,…

The Energy Out West conference is held every other year and began in 1996 when a group of people doing weatherization work in the Northwest thought they could help each other do it better. The current president of Energy Out West (EOW) is Mimi Burbage, who should be familiar to readers of Home Energy and anyone in weatherization. Mimi brings that independent, Alaska, straight talk style to whatever she does, from heading the Alaska Housing Finance Corporation to her work for EOW.…Continue
So, you're about to take a class to become a home energy rater or building analyst so you can go out and do energy audits. Maybe you've already taken a class and are out there trying to make a living at it now. You may be aware of this already, but…Continue
