With political campaigns going at full speed, mailboxes across the country are going to be stretched to the breaking point in the coming weeks with direct mail, promises, and pleas from elections national and local. This overstuffing could impact your company's direct mail if you’re not careful.
It looks like the spigot of new HCFC-22 will be totally shut off as of 2020. The so-called “service tail” of HCFCs from that date until 2030 apparently will not include the most widely used refrigerant in the HVACR sector. That was the perspective of Dave Godwin of the EPA, speaking at a recent conference.
Good news is on the horizon as newly released industry numbers from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) show multiple increases in factory shipments. According to AHRI, the combined U.S. factory shipments of central air conditioners and air-source heat pumps for July are up 6.2 percent as compared with July of last year.
Higher efficiency and improved comfort are some of the main features of today’s air movement and control systems. Savings can be hard to quantify, because more often than not they depend on changing conditions, such as weather patterns and the cost of fuel.
HVAC and facilities professionals have known for years the importance of controlling the intake of outside air to maximize occupant comfort while reducing unnecessary energy usage. Demand control ventilation (DCV) systems address this issue by modifying external air intake based on building occupancy.
How important is your tech’s appearance? For that matter, how important is any appearance to how your company is perceived? And are your competitors concerned about appearance, too? These are some of the questions we asked visitors to our recent “Survey Says” online survey at www.achrnews.com.
In order for the upper floor of a home to be near the temperature of the lower floor(s), the natural inclination of warm air to stratify upstairs has to be overcome.

When it comes to evaluating the current economic climate, it all depends on who you ask - and the opinions are as diverse as America itself. Ask a host of HVACR contractors across the nation what they are experiencing and how they are handling the current economic climate, and some of the answers will be pretty interesting.
The EPA reports that indoor levels of pollutants may be two to five times higher, and occasionally more than 100 times higher, than outdoor levels, which could lead building occupants to suffer from respiratory ailments. Riding to the rescue are HVAC professionals who are specially trained in the latest IAQ technology.
Technology provides many tools for accurate and reliable fan and system design. Gone are the days when cheap energy allowed the use of rules of thumb and large safety factors. But even with modern technology, instances occur when the application does not perform as expected. That’s when we need to apply troubleshooting.
