3 Things You Should Know About Air Conditioning
Home air conditioning in our hot and humid client isn’t a luxury; it’s a necessity. Given the expense of purchasing the equipment and the power it takes to operate it every day, being informed about how to care for it only makes good sense.
Because air conditioning is more than keeping your house cool. It also frees the air from excessive humidity, efficiently removes air microorganisms like dust, soot, and dander, as well as properly ventilating every room in your home.
A Ton Of Cooling
Talk with a HVAC contractor about air conditioners and you may hear them refer to it by the ton: a 4 ton air conditioner. They aren’t talking about weight; rather it’s a number that tells how much heat the air conditioner can remove from the house in an hour.
Before the modern day air conditioner was introduced into the marketplace, people cooled their home and buildings with ice. When cooling machines began entering the scene, they rated their capacity by the amount of ice melted in one day, which is where the term “ton” came from when sizing air conditioners.
A ton of cooling is now defined as delivering 12,000 BTU/hour of cooling. A small home may require around two tons, whereas a large one can be up to five or more. So an air conditioner in a small home may be referred to as a two ton air conditioner, meaning it would deliver 24,000 BTU/hour.
What Filters Really Do
Any HVAC company will tell you your air filter is an important part of your HVAC system. They’ll recommend replacing it on a regular basis.
The filter removes particles from the air stream to keep the air conditioning unit clean and to remove particles from the air. As the air filter does its job, it fills with more and more of these particles. In some ways, it makes the process of “catching” particles more efficient, but it also increases resistance and begins to reduce airflow. This is when it’s time to change the filter.
If you don’t change the filter, air flow begins decreasing rapidly, and the system begins to not perform as well as it should. And if it gets too dirty, it becomes a source of air pollution itself.
If you take the filter completely out of the system, you would reduce the air flow problem, but would also allow particles the filter caught to begin building up on your evaporator coil and eventually cause it to fail. New filters are easier to change and a lot cheaper.
It’s not just the air conditioning unit that matters. Another reason systems may appear not to be working is because of a duct leak. Duct leakage can allow up to 40 percent of the energy produced by the air conditioner to seep out before it reaches its final destination. Ducts in attics, crawlspaces and garages need to be well insulated to prevent leaks. They need to be cleaned and well maintained to run as efficiently as possible.
