The June, 2017 issue of Chief Engineer magazine featured a big article on Airways' Aeroseal® duct sealing service. It did a great job of describing what Aeroseal is all about -- how it works and why you might consider having it done. Check it out here!
Just about everyone who operates a commercial or institutional cooking operation understands that at some point the exhaust system needs to be cleaned because the grease buildup in the exhaust system is a fire hazard. But not everyone understands the standards that govern the design and maintenance of systems.
Keeping condenser and evaporator coils is critical to the efficient operation of an HVAC system. Over time, coils accumulate dust, dirt, pollen and other contaminants. This gets expensive in three ways: The buildup serves as an insulator, cutting down on the effectiveness of the coils. It also cuts down on the air flow. Both of these cost you money by making your system work harder. That, in turn, runs the risk of accelerating the need for repairs and maintenance. Cleaning coils is a tricky business. If you’re not careful, you can pack in the dirt, and or damage some of the parts.
