Portable Commercial Air Conditioner
Since the invention of air conditioning in 1922, the public has grown accustomed to having instant cooling or heating at the push of a button. 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 […]
Commercial vs Residential HVAC
While the commercial and residential HVAC industries have similarities there are differences as well. No matter what type of HVAC being deployed, the purpose always comes down to cooling, heating, dehumidification, and ventilation. Some of the key differences involve size, location and manufacturing. While there are HVAC manufacturers that specialize in one or the other, […]
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 […]
Improving Indoor air hygiene
Since the onset of the novel corona virus that has become a pandemic, there is emphasis placed on improving indoor hygiene. People across the globe now realize that prevention of illness needs to be part of the strategy to control infection. Although mask wearing and social distancing may reduce transmission it is not enough to solve […]
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 […]
What is a Water Source Heat Pump?
When it comes to reliability and efficiency, a Water Source Heat Pump (WSHP) could be the best option for commercial buildings. A Water Source Heat Pump works much in the same way as an air source heat pump; but extracts and disperses heat by water instead of air. An air source uses heat from the […]
Air Conditioning Installation & Replacement
The sustainability of a commercial building depends greatly on the performance of its air conditioning system. Furthermore, regulations are increasingly requiring that buildings maintain a healthy supply of fresh outside air. These systems are required for the comfort of occupants and for critical functions like server rooms and other sensitive equipment. Eventually, every HVAC system […]
Energy Recovery Wheels for Max Energy Savings
What is an Energy Recovery Wheel? One of the best ways to make a DOAS unit function more efficiently is to add an Energy Recovery Wheel (ERW). In many cases local codes make it necessary for HVAC units to meet minimum standards for efficiency. An ERW also called an Enthalpy wheel works as part of […]
Improving Indoor Air Quality in Commercial Buildings
Indoor Air Quality Indoor air can be considerably more detrimental to people’s health than outside air. With this in mind, it is important to identify where indoor air contaminants originate and address the possible health effects. To begin with, we can improve indoor air quality Particulate matter Carbon Monoxide Secondhand tobacco smoke Pesticides Solvents Volatile […]
What ERVs Can’t Do
Background Energy recovery ventilators (ERVs) have flooded the HVAC market. Building owners want more fresh air in their buildings, but don’t want to pay the costs associated with conditioning it. They know it is far more costly to remove heat and humidity from 95° air than it is to do the same with return air. […]
Compressor Failure and the Effects on Warranty
Identifying why compressor failure is subject to many variables and is important to understanding warranty implications. Although compressors fail for a multitude of reasons, poor installation and maintenance are the most common causes. However, for the vast majority of compressors returned for claims, rarely is it due to a defect in the manufacturer supplied part. […]
