4 Things You Shoud Know About HVAC Work

If you have heard the term HVAC and were not sure of its meaning, you are in for an explanation. HVAC is an acronym for heating, ventilation and air-conditioning. It consists of all the different branches of heating, ventilation and air-conditioning equipment. You may have seen HVAC ductwork in various buildings or homes. In HVAC, every component has a function, for instance, the air conditioner uses a refrigerant (Freon but recently CFC-free refrigerants are being preferred) evaporation to lower room temperature, the heating element uses a small furnace or a heat pump (the better and modern alternative to furnaces) to diffuse heated air into a closing, by sucking in the cooler air and passing it through the heated metal or pipes.

How do HVAC systems work?

It is not easy explaining how HVAC systems work, but for further convenience, let’s break it down to four components. These are all normally incorporated into HVAC duct work and the following details have been kept to as few technicalities as possible. Any technician how installs an HVAC system must have proper hvac training so that he properly installs your system and uses the most suitable HVAC parts.

1. Furnace
A furnace is part of a system that pulls in outside fresh air, and passes it into the home. It then sucks in the air from inside, and retaining most of its energy, exhausts it outside. This way, the energy is consumed but the room stays fresh and healthy. It consists of a pump and a blower wheel.

2. Air-Conditioning
Air conditioning basically works on the same principal, but it involves a refrigerant instead of a furnace and sucks in warm air, and gives off fresh cool air from the outside. Note: a heat pump and fan coil work basically on the same concept, but the heating and cooling function is taken care of by an electronically powered air pump and fan coil.

3. Zoning system
A zoning system helps to moderate room temperature according to the needs of the homeowner by incorporating a thermostat that can be altered to turn the room temperature up or down. If one portion, for instance, requires more cooling then the other, the cooler air from the other room is pumped into the room that requires it more. This system conserves energy and works wonders and is prompt as well due to its energy management system.

4. Packaged system
A packaged system is a hybrid unit that has both the heat pump and the fan coil. Some systems also have the ability to switch to natural gas for heating and electricity for air conditioning. This allows you to save on electricity in the winter.

If you are interested in learning more about HVAC work you may find some interesting information on HVAC talk, a forum for HVAC topics.

If you are looking for alternatives with easier installations for heating or cooling, portable units are a good choice. There are also ceiling fans that work both to heat and cool. A ceiling fan heater does a good job at heating a room.
