However, there are times that for various reasons life isn’t so simple. In some instances, the need for AC may be in a remote place such as an outdoor tent […]
BTUs in Air Conditioning
When it comes to air conditioning, calculating BTUs is an essential part of determining the size of the unit. A BTU or British Thermal Unit is the measure of heat energy that comes from a thermal unit and an Imperial Gallon is 10 pounds in weight. Therefore, a BTU is 1/10 of an Imperial Gallon […]
Packaged HVAC Indoor vs Outdoor
There are two basic types of HVAC systems, that being packaged and split systems. In short, a split system model contains a condenser and compressor residing in an outdoor cabinet while connected to an indoor evaporator. They connection by copper tubing and include various line lengths depending on numerous factors. Packaged systems on the other […]

How HVAC Retrofit Can Benefit Commercial Buildings
Every day there is a commercial HVAC system that is starting to fail as it reaches the end of its lifespan. Even well-maintained systems have components that will wear out. On top of that, the needs of a building change overtime as perhaps more people occupy the space. There could also be a change in […]
Understanding DOAS and comfort cooling differences
While indoor air quality and ventilation have been major focuses of the HVAC industry for a long time, many misconceptions remain about what these applications require in terms of equipment and design. Today’s post will parse some of the most common questions about DOAS and comfort cooling equipment. Purpose of DOAS A dedicated outside air […]
What is DOAS?
With Independence Day weekend approaching Americans are making plans to celebrate with cookouts, swimming, and other outdoors activities. These simple pleasures become even sweeter knowing that, when outside, we are breathing clean, fresh air.

The Natural Disinfectant of UV-C Light
Due in part to recent pandemics, ultraviolet light is making a revival in the area of disinfecting air and surfaces in HVAC applications. Using UV-C light as a disinfectant is hardly a new concept. As early as 1878 Arthur Downes and Thomas P. Blunt, published a paper describing the sterilization of bacteria exposed to short-wavelength […]
BACnet Building Automation and Control Network
BACnet (Building Automation and Control Network), is the communications protocol that defines communication services used between building control systems and building automation end-devices. The protocol displays how data is represented and moved between BACnet nodes on the network and the services used to move it. For example, by sharing sensors and data, BACnet gives our […]
Recovering Energy from Class 2 Exhaust Air
The Problem Providing a healthy environment must be the top priority for any air conditioning design. This can be difficult though, especially in spaces that generate less-than-ideal breathing conditions. Nail salons, health clubs, and bathrooms are just a few examples of spaces where processes or people taint the air with undesirable chemicals or odors. In […]
Industrial Grow Room Units
As cannabis becomes legalized or decriminalized throughout the United States, Grow Room units are in high demand. Medical applications of the plant alone have led to further community acceptance and therefore more facilities have emerged for growth and distribution. In order for this up-and-coming industry to thrive, HVAC companies have developed specialized equipment that promotes […]
Retrofitting Commercial HVAC Units
Retrofitting Major Commercial HVAC Brands Millions of HVAC systems are reaching replacement age. The life cycle for most will pass several times over the life of commercial, industrial and institutional structures. Estimates show that there are over 5 million buildings available for retrofit HVAC upgrades. While 70% of commercial buildings built prior to 1980 have […]
