In 2011 A K Brown purchased a new Lockformer Triplex Machine that uses scrap metal from our metal manufacturing shop to fabricate made to measure slip and drive cleats that are of quality equal to or better than purchased at any supplier. This machine uses scrap metal as small as 10″x 2.5″ to manufacture slip and drive cleats that are used by the hundreds on virtually every duct work installation.
This not only reduces waste going to the scrap yard but also eliminates transportation costs and allows us to manufacture made to measure components that reduce installation time. Bottom line: More value for our customer and better for the environment!!
Many buildings built during the boom of the seventy's and earlier have terminal reheat systems or VAV systems with a hot water radiant loop on the perimeter. These systems as originally designed gave no consideration to energy consumption or the environment. An analogy of how these systems operate is that like driving your car with your foot on the gas full throttle and putting your foot on the brakes to slow down.
any air filter have an efficiency of only 10%. If you are changing your air filters on a regular basis and your air vents are dirty, you may want to upgrade the efficiency of your air filters
Most modern heating equipment is designed for a maximum temperature increase of 25ºC to 45ºC, while it is actively heating. If your air filters become dirty and reduce air flow, the efficiency of the unit substantially is reduced and relies on the high limit to cycle the burner off. This reduces the life of the heat exchanger and leads to high limit failure.
here are hundreds of moving parts in a roof top heating and cooling systems. Many of these parts require the coolant and oil level in the system to be at proper level to provide lubrication and cooling. In fact, some A/C system with low refrigerant level may maintain proper room temperature but overheat the motor windings of the compressor which will thermal age the compressor. Next to an A/C set too low, this is the #2 leading cause of premature compressor failure
ost A/C units are designed to provide a room temperature of 20?C. Setting thermostats lower then 20?C risks freezing up the cooling coil which reduces the efficiency of the equipment, will reduce the capacity to the point that it will not cool at all and eventfully damage the compressor… costing several hundred dollars to repair. Thermostats set too cold is the number one cause of premature compressor failure.
