Every facility has untapped Energy savings potential
Most facilities have existing air conditioning equipment that may not be working as efficiently as possible. To reap the benefits of Energy savings and / or provide a more comfortable environment, an owner can either replace components with more efficient systems or possibly modify / retrofit existing equipment for optimization at a fraction of the cost to replace.

Some Energy Savings Tips & Technology
One of the easiest ways to save energy on an air conditioning system is to keep the condenser coils clean and free of debris. A dirty coil (as the one below) could cost you an additional 15% on you HVAC energy bill. Properly cleaned coils on a semi-annual basis is the right answer for most systems. Don't forget that it's against EPA guidelines to flush the debris/cleaning solution to a storm drain, so make sure that your cleaning crew is trained to meet EPA requirements.
A "must have" on most larger evaporator fan motors is a Variable Frequency Drive (VFD). Variable torque loads, such as, Centrifugal fans and pump loads operated with a VFD will reduce energy consumption. Centrifugal fans and pumps follow a variable torque load, which has horsepower proportional to the cube of speed and torque varying proportional to the square of speed, also known as the "Affinity Laws". EXAMPLE: if the speed of a fan is cut in half, the horsepower needed to run the fan at load is cut by a factor of eight (1/2)3 = 1/8.
There are many other benefits to using a VFD: Controlled start current, reduced power line disturbances, lower power demand on start, controlled acceleration, adjustable operating speed, adjustable torque limit, controlled stopping, and elimination of mechanical drive components.
There are now HVAC coatings available that can be applied (factory or field) to Condenser and evaporator coils for energy conservation. California energy companies have shown an approximate savings of 9% on average. These coatings can also reduce or even eliminate corrosion and enhance air flow through the coil.
- Unmatched Efficiency as low as .31 kw/ton IPLV.
- 100% Oil Free eliminates oil system maintenance costs.
- Magnetic Bearings eliminate frictional losses.
- One moving part assures long service life.
- Low In-Rush Current reduces installed cost and peak load.
- Lowest Noise - Only 72 dBa.
HVAC savings have been recorded at 18% + when coating outdoor package units or air handlers and attached duct work. Ceramic-based, water-borne insulating coating are designed to block heat load, moisture penetration, and air infiltration over a surface - all while reducing important energy costs. They can reflect over 95% of the three radiation sources from the sun: ultraviolet, visual light and infrared rays.
Make sure your installation consists of a ceramic coating that blocks a broad range of heat load from the sun, ultraviolet, visual light and infrared rays
all contribute to strain on your system. The ability of the coating to reject this broad range will be dependent on the ceramic(s) within the coating, so each brand will perform differently. Gauge the performance by how close to ambient temperature the surface of your equipment and ductwork becomes after application. Surface temperatures of 5-8 degrees of ambient are achievable.
KEEP HEAD PRESSURE DOWN:
There are many ways to save energy on existing HVAC equipment. Many of them are mentioned on this site. However, remember that any method of reducing head pressure on an air conditioner or chiller will help you keep your facility cooler and more efficient. Lower head pressure means lower evaporator pressure, which means cooler supply air, which can mean less HVAC run time. They all mean "energy savings"!
