Your HVAC (Heating, Ventilation and Air Conditioning) system or Central Air Units may be some of the most important appliances that you own. This is especially true during the summer when the heat gets oppressive, and it gets difficult to stay outdoors. To ensure that your AC functions at peak efficiency it is important to have the unit serviced regularly. With most systems, the recommended service times are once a year before they are put into heavy use. For most homeowners, the best choice is early spring or the beginning of summer.
The most crucial components in an air conditioner are the condenser and the refrigerant that it compresses. The refrigerant is important because it is used to collect heat from the building. However, the level of the refrigerant is also important for efficient function because it carries the lubricant required to keep the condenser cool and properly lubricated. If the refrigerant is low, then the condenser may have problems compressing it correctly. This in turn could shut the system down because an air conditioner requires a specific volume of refrigerant to function properly.
To move the heat from your home, the condenser compresses the refrigerant which causes a state change. This allows the refrigerant to move through the evaporator coil and accumulate any heat around that coil. Collecting heat in this way chills the metal the coil is made from, and this coolness is spread through the home via the blower. It is vital to keep this coil clean, and part of this is replacing the filter on a regular basis. A dirty filter can allow a lot of gunk into the system that could clog the evaporator coil or accumulate on the blower.
When it comes time to replace your Central Air Units, you want to hire an expert. Many companies will simply toss in a system that seems to match, but this may not be the best choice for your home. In some cases, the unit may not actually be the right size to cool your house properly. An expert in HVAC systems such as Poudre Valley Air can calculate the size of your home as well as allow for any odd sized rooms to ensure that your house is cooled properly. This could be very important in homes with vaulted ceilings or large open foyers. You can like them on Twitter.
