Not only is it nearly imposible to grow your company as long as you’re working “in” it, but because you’re the one controlling everything, you’re often the biggest bottleneck.
As the leaves change colors and crisp fall nights descend upon us, the spectre of carbon monoxide (CO) hangs over homes all across the country. The familiar smell of dust burning off heat exchangers is a grim reminder that we’ll soon see more news stories about families severely injured or killed by this silent killer.
Foam insulation has been around for quite some time, but recent improvements to the products and application methods have made this approach to insulating homes and buildings more attractive than ever. There’s a good chance you’ll work on a foamed house in the near future. If you’re lucky, you’ll be brought into a project where the entire home was foamed, or better yet, you’ll get a chance to work on a new home where you can design and install with foam insulation in mind.

I do, however, think that regardless of whether the science is good or bad, we have an obligation to be good stewards of this earth during our short visit here.
Have you gone “green” yet? Here’s a reality check: whether you believe in global warming or not, the U.S. is jumping on the big GREEN WAVE that’s building momentum worldwide, soon to reach tsunami proportions. It’s become part of our language with words like carbon footprints, carbon credits and white tags now being bandied about in Hollywood and corporate boardrooms.

A fairly recent study performed by Advanced Energy in North Carolina found that 90% of HVAC systems don’t perform as they should.
Air conditioning and related product sales really got heated during the 1960s. Residential HVAC became more accessible for more homeowners, and building owners were having rooftop systems installed on new and existing buildings. Here's a gallery of HVACR advertising from the 1960s.

New technology allows a current switch to be configured outside of an electrical enclosure and installed on a cold wire, thereby eliminating the need for a PPE suite and preventing arc flash hazard. PPE suits, worn by technicians working in a live enclosure, are often cumbersome and can hinder the installer’s ability to configure an adjustable current switch....More
