In many areas of the country, there is one critical and nearly lifesaving invention most homes have- and that is central heating and air. Of these, air can be the most in-demand as there is only so much you can do to cool down without turning on the air conditioner. As highlighted in this informative YouTube video, residential air conditioning is one of the systems that often get the most service calls. This is often true at the start of the warm seasons as the systems have sat unused and basically ignored for months during the winter and may have some issues that need to be dealt with.
Taking care of the residential air conditioning systems requires expert care and attention and needs to be done at a minimum of once a year though most experts recommend twice-yearly inspections and maintenance work. Checking the system before the hot or the cold seasons starts helps ensure everything is in good working order before the system gets used. In areas where winter and summer weather is prolonged, more frequent checks may be required to ensure the excessive use is not breaking things down faster than normal.
