Your Air
Healthy air scientists have known for more than 50 years that the most effective sterilizer for airborne contaminants it natural sunlight. Not the sunlight we see everyday but the invisible ultraviolet rays. Adding a UV light to your heating and air conditioning system is a proven way to make your building a healthier place to work. UV has been proven effective in hospitals, restaurants, schools, daycare centers, nursing homes and hotels.

Filters
Air filters play two important roles in an HVAC system; they help maintain indoor air quality and they protect downstream components of an air handling system from accumulating dirt. Dirty air filters cause your A/C and heating systems to work harder and use more electricity. When your system works harder, it not only uses more energy but it breaks down more often. A clogged filter can cause from 10% to 23% reduction in air flow and increases operating costs from 7% to 11%.

Your Water
Backflow Preventers
Are your backflow preventers certified? Each water supplier should ensure that a proper backflow preventer is installed and maintained at the water service connection to each system or premises that poses a significant hazard to the public water system. Ensure that a proper backflow preventer is installed and maintained at each water loading station owned or operated by the water supply.

Your Efficiency
Dirty Coils
Did you know that when your condenser coils are dirty on your outdoor unit the efficiency of your equipment drops off dramatically and can cause system failure due to high head pressure? This can lead to unwanted costly repairs and down time. As spring arrives unfortunately so do cottonweed and bugs. To help keep your condenser coils from being plugged use coil filters. They can isolate debris on the outside of the unit for quick and easy cleaning. These filters will increase efficiency and help keep your coils clean all season long.

Condensate Pans and Traps
Are your drain pans allowed to accumulate water? Drain pans must drain completely and must be designed such to preclude the buildup of microbial slime. Use of microbial tablets within the condensate drain pans periodically during cooling season helps to greatly reduce the buildup of this microbial slime. Severe high humidity/high temperature days in the summer will promote more condensate off of the cooling coils and because of this, may allow the pan to be constantly filled at times.

Chillers
Give your chillers a spring check-up. The overall goal of preventive maintenance for chillers is to improve chiller reliability, increase equipment life and maintain peak energy efficiency. A well organized schedule of routine checkups and minor repairs reduces the frequency of unscheduled, often expensive service calls and minimizes the risk of equipment failure and the associated potential for downtime, injuries, and unbudgeted, costly equipment replacement. A thorough inspection and service of the chiller system now will keep it “humming” all summer long, while helping achieve longer term operating goals.
