The condenser is the component that rejects the heat from the system. Most equipment is air cooled and rejects heat to the air. The coils are copper or aluminum and both types have aluminum fins to add to the heat exchange surface area.
High humidity within homes creates numerous problems. Despite the many home-related humidity issues, there has been little to no measured data available on actual indoor humidity levels in U.S. households. That is why the U.S. Department of Housing and Urban Development (HUD) funded Steven Winter Associates Inc. (SWA) to collect data from homes on interior humidity levels.
This article should really be titled “Miracle Closing Technique for the Estimate-Getting Researcher.” As you will read, it’s really not a miracle at all. It’s more common sense. There are many kinds of customers, but the most classic might be the we’re-getting-estimates customer.

After 85 years, it takes more than cosmetics to keep a publication fresh; the right attitude needs to permeate the organization. “This publication, The NEWS, was started by my great-grandfather in 1926,” said BNP Media co-CEO Taggart Henderson.
Congratulations to Bernard Nagengast, an engineering consultant and industry historian who found the oldest NEWS issue among our readers. His oldest issue was dated Nov. 30, 1926. The very first issue of the magazine was published in September of that same year.
We all create our own individual histories every day. At the same time, we become part of a larger history. With that in mind, we asked a few industry colleagues what the most significant changes were that they have witnessed in the HVACR industry.
After being in the HVAC industry as a contractor and a rater for 30 years, I’ve seen a lot of things that have been done wrong. But really, there has never been a system in place that required contractors to do things correctly - and verified that they had. All that is changing with the Energy Star for New Homes version 3.
In 1926, F.M. Cockrell started Business News Publishing Co., now BNP Media, in Detroit. The first issue of the Electric Refrigeration News, now The Air Conditioning, Heating & Refrigeration NEWS, had a publication date of Sept. 11, 1926. It was created to help recognize the importance of the expanding electric refrigeration market.
You may be familiar with the Energy Star® label on energy efficient heating and cooling equipment, but did you know there are also Quality Installation (QI) guidelines to help ensure that heating and cooling equipment is installed properly? Nearly half of all heating and cooling equipment in U.S. homes never performs to the advertised capacity and efficiency due to installation problems.
