Phoenix Residential HVAC: What is HVAC?

The choice of a Phoenix residential HVAC system can be overwhelming and intimidating —after all, an HVAC is one of the largest and most costly purchases the average family will incur. Consequently, understanding HVAC is an important first step. So, what is HVAC?

HVAC is a frequently used term in the heating and cooling industry. It is an acronym for "heating, ventilation and air conditioning”. These are the three crucial comfort functions that are combined into a single system. Heated, chilled, or dehumidified air flows through multiple tubes, also known as ducts, to be relocated among all the rooms of your home. A central HVAC system is the most quiet and favorable way to cool an entire home comfortably.

Unless you live in an incredibly moderate climate, the HVAC system in your house uses the most energy and will cost more monthly than any other system in your residence. Commonly, around forty-four percent of your utility bill goes toward your HVAC system.

For a Phoenix residential HVAC system, the cooling is the most crucial element of an HVAC system for a large part of the year. The A/C unit in a central cooling system provides cool air through ducts within your house by creating a process that pulls out the warm air from inside, removing its heat.

In a split system, the compressor condenses and circulates the refrigerant through the outdoor air conditioner, morphing it from a gas to a liquid. The liquid is then forced through the evaporator coil or cooling compartment found within the home. The indoor air conditioner’s fan circulates the air that is inside the unit, causing it to pass across the evaporator fins. The evaporator’s metal fin interchanges the thermal energy with the air next to it. There, the refrigerant changes from liquid into vapor, removing any heat from the area. As the heat is decreased, the air is cooled and blown back into the residence.

After that, the condenser or outdoor unit changes the refrigerant vapor back into a liquid, again ridding it of any heat. By the time the fluid leaves the evaporator again, it is a cool, low-pressure gas, eventually getting back to the condenser to start its journey all over again. This process continues multiple times until your house gets to the comfort level you want, as set and sensed by your thermostat.
