In recent months, some of my customers have inquired about heating and air conditioning cleanings and their relevance to the equipment’s proper service. I decided to write this article to address a few key issues that may arise if annual maintenance is not performed. To ensure safety and proper system operation, a competent heating and air conditioning company should conduct two essential cleanings. For the purposes of this report, we’ll divide the cleanings into two sections (furnace cleaning and air conditioning cleaning) and focus on one at a time. Checkout Emergency Plumber near me.
Clean and inspect the air conditioning system
An air conditioning system has a huge job to do when it first starts up for the summer after being idle and not in operation for the whole winter. The state of the refrigerant in the device is changed from a liquid to a gas in an air conditioning condensing unit (outside unit). This creates a heat transfer and cools the air in your home through a coil. So the part that compresses the refrigerant back to a liquid has not been used in 7 months and is lubricated through the refrigerant.
For a first-time reader, the last paragraph is a lot to take in, but it gives you an understanding of the system’s complexity and the value of maintaining it. So there are some initial visual and audio tells we look for when a heating and air conditioning contractor comes to look at the device for the first time of the year and turns the machine on. This is a vital aspect of the year’s first runup to ensure that the machine is not damaged. If the freon levels appear to be off or the compressor sounds unusual, the contractor may turn off the device and inspect it for damage. Cleaning will begin after an initial inspection of the device and ensuring proper cycling.
The second part of this essential air conditioning annual maintenance is to clean the machine properly. The condensing unit’s fins resemble those of an engine radiator. The refrigerant is passed through tubes and fins, and air is passed through them using a fan. Every summer, this coil becomes extremely clogged, and it must be cleaned at least once a year. The issue arises when the homeowner uses a garden hose to clean the coil from the outside in order to remove leaves and debris. This just drives the debris deeper into the coil, plugging it even further.
The only way to clean a coil properly is to remove the fan and open the top of the condensing unit. Then, using either nitrogen or water, clean the coil from the inside out, starting at the top and working your way down. Some companies clean the coil with chemicals, but this is not recommended for use every year. There should be no need to use chemicals to disinfect the unit if it is cleaned properly every year.
