D&L INC About Air Conditioning & HVAC


Heating, ventilation, and air conditioning (HVAC) is the technology for regulating a room’s temperature to comfortable levels. It’s goal is to provide thermal comfort and acceptable indoor air quality. AC units are used for both domestic and industrial purposes to maintain temperatures to certain levels. They work by removing heated air from inside of a building, forcing it outside. HVAC systems have become a required industry standard for construction of new buildings. When properly designed and maintained, the system will provide a comfortable indoor environment year round.

An air conditioning system, better known as an air conditioner, can provide cooling and humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system. Outside, fresh air is generally drawn into the system, into the indoor heat exchanger section, creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of a vent.  Air conditioning and refrigeration are provided through the removal of heat.

An average lifespan of an AC unit is about 10 - 15 years. Most AC systems need regular yearly services after 2 years of initially being installed. During that time, some AC systems may need maintenance more or less often than others. The life expectancy of the HVAC system can be increased with proper servicing at regular intervals of time. Getting trained technicians to fix your air conditioning system can help you get the most time out of your unit.
