The US Census Bureau publishes information on characteristics of new homes started, including air conditioning and heating systems. Before trying to carry out air conditioner repair in your home or office, there are certain aspects of air conditioning systems you should know about. When their air conditioning system breaks down or develops a fault, many people try to fix it themselves without fully understanding the concepts involved. However, it is possible for you to carry out a basic air conditioner service once you understand the principles, although HVAC repair (heating, ventilation and air conditioning) is best left to the professionals. If you have these devices at home you may end up needing ac repair Columbia SC to maintain it working properly.
The normal home or office air conditioner works by simple physics, and consists of two discrete units: the condenser and the evaporator. In the condenser, Freon gas is put under pressure then passed through a heat exchanger, removing heat from the gas and converting it to a liquid. It is then passed through an expansion valve into the evaporator; the liquid Freon expands and evaporates to a gas, the latent heat needed for this coming from the environment, which is then cooled (the cooled air then being blown into the room). The gas heated by the higher room air temperature than goes back into the condenser where the heat is removed and the cycle continues. Both the evaporator and condenser are sealed units and you cannot carry out any air conditioner repairs to these yourself: you will have to call a trained professional. What you can do is to keep everything clean and all the mesh guards and so on clear of debris. You can carry out simple air conditioner service yourself, but not HVAC repair. Here are some basic air conditioner repair, troubleshooting and service tips. For more information regarding to AC repair service, Visit us at www.waychoffsac.com.
In 2015, approximately 93 percent of new homes started in the US had central AC. Central AC has been a common feature in new homes for some time, but its share did grow some between 2000 and 2015, going from 86 percent to 93 percent.
The share of new homes with central AC differs by Census Division (Figure 1). The New England and Pacific divisions, which have more temperate climates, have lower rates of central AC installed (73 percent and 69 percent in 2015, respectively). In contrast, in regions that are hotter and more humid, all or nearly all of the new homes started have central AC: for example, in the South Atlantic (100 percent), East South Central (100 percent), and the West South Central Divisions (99 percent).
The majority of new homes started in 2015 have either a forced air system (55 percent) or an air or ground source heat pump system (42 percent). It requires A/C service, repair and installation. The share of new homes that have a heat pump has grown over time, going from 23 percent in 2000 to 42 percent in 2015. Meanwhile, the share with a forced air system has declined, going from 71 percent in 2000 to 55 percent in 2015.
Heat pumps are more prevalent in Southern regions where air and ground temperatures don’t fall as much (Figure 2): East South Central (75 percent), South Atlantic (74 percent), and West South Central (45 percent). They are less so in the West North Central (29 percent), Pacific (14 percent), Middle Atlantic (13 percent), Mountain (12 percent), East North Central (11) percent, and New England divisions (4 percent).
The majority of new homes started had their heating systems powered by either electricity (40 percent) or natural gas (55 percent) in 2015. In regions such as the Middle Atlantic and New England, where electricity tends to be more expensive, the share of new homes with systems powered by electricity is low (13 and 5 percent, respectively). On the other hand, systems powered by electricity are more common in the south: for example, the South Atlantic (72 percent), the East South Central (71 percent), and the West South Central (41 percent).
