CapitalHvac.com - HVAC heating and Air Conditioning The HVAC system uses three closely related functions, namely, heating, ventilation, and air-conditioning. These functions are uniquely set up so that they can regulate temperature and humidity in residential homes, public offices, and other building facilities with respect to the overall design of the structures. The heating system can either be central or local. The most commonly used setup is the central heating system where the heating is concentrated in one area—central—and is then circulated for various heating processes and applications. Heat values of fuels are based on BTU to cubic foot measurement for HVAC. in Public bookmarkswith airandcapitalhvac.comconditioningheatinghvac

HvacNation.com - Information about HVAC Tools Getting the right HVAC tools and gauges is as important as having the right ingredients in cooking. Furthermore, utilizing the right tools is one big step in having the right system. Thus, it is advisable for HVAC practitioners, especially for beginners, to know what basic tools are currently used today. One basic HVAC tool is the wrench. This device is used to tighten or loosen bolts (usually those with hex heads) and nuts. There are many kinds of wrenches: open-end, combination, adjustable open-end, flare nut.
