You Should Perform Maintenance On Your Air Conditioning Unit Annually

There has been some question from my customers in the past few months about heating

and air conditioning Cleanings and their importance to the proper operation of the equipment. I wanted to write this article to discuss a few important issues that can occur in absence of the annual maintenance. There are two important cleanings that need to be performed by a qualified heating and air conditioning company to ensure safety and proper system operation. For the sake of this article we will split up the cleanings into two separate articles (furnace cleaning and air conditioning cleaning) and only discuss one at a time.

After a complete winter of being asleep and not in use, an aircon system has a gigantic job at task on first starting for the summer. The way an aircon condensing unit ( outside unit ) works is by changing the state of the refrigerant in the system from a liquid to a gas. This generates a heat transfer and cools the air thru a coil within your house. So after seven months of not being utilized the element that compresses the refrigerant back to a liquid hasn't been used and lubricated through the refrigerant.

That last paragraph is a lot to handle for your very first time reading, nonetheless it gives a notion of the intricacy of the system and the seriousness to maintain it. So when a heating and air-con contractor comes to have a look at the system for the 1st time of the year and turns the unit on there are some 1st visible and audio tells we look out for. This is a crucial part of the first runup of the year to guarantee there's no damage caused to the unit. If something looks wrong in the freon levels or the compressor sounds aberrant the contractor can shut the unit down and evaluate the unit for damage. After primary inspection of the unit and guaranteeing correct cycling of the unit the cleaning would begin.

Cleaning the unit properly is the second part to this important air conditioning annual maintenance. The fins on the condensing unit are like a automobile radiator. They use tubes and fins to run the refrigerant through and pass air across that using a fan. This coil gets very clogged every summer and need to be cleaned each and every year. The problem comes when the homeowner sprays the coil from the outside in the get the leaves and debris off. This just pushes the debris more into the coil and plugs it even further.

The sole correct way to scrub a coil is to open the head of the condensing unit and take the fan off. Then by employing either nitrogen or water, spray from the interior out cleaning the coil from the top to the bottom. Some corporations use chemicals to wash the coil, but this isn't meant for each year use. With correct yearly cleaning there shouldn't be any reason to use chemicals to scrub the unit.

After the initial check of the unit working and cleaning of the unit the contractor will check the refrigerant levels of the unit. This is somewhat of a process because of all the different factors that are involved with a proper running air conditioning unit. If the outside and inside coils are clean, and there is proper airflow in the home, your unit can properly be checked for freon levels.

There is a good amount more involved in how an air conditioning system works, but for the cleaning and maintenance this should be enough information. By performing the maintenance every year you can have the personal assurance that your equipment will last a long time without having any major issues to inconvenience your family.
