Products that test and monitor make working with and on units so much easier for contractors and technicians, including when it comes to troubleshooting. The winners of the Testing & Monitoring Products category of the 2011 Dealer Design Awards share these traits.
The first step in evaluating a building’s energy use involves an energy audit. This consists of various home performance tests that identify opportunities to reduce energy use. More HVAC contractors are starting to offer this service because of its direct impact on a home’s heating-cooling costs.
Is online buying becoming just as important as one phone call and a pickup at the parts counter?

The gravity of refrigerant leakage has evoked fines from the EPA of up to $25,000 per day for each violation. The unfortunate reality is that refrigerant leak sites are usually discovered only after there has been a loss of cooling due to discomfort, spoilage, or production difficulty. Repairing refrigerant leaks is not the problem - finding them is.
Nearly 55,000 people ambled through the Las Vegas Convention Center during three days of non-stop activity at the industry’s largest trade show.
