4 Important Things to Consider when Sizing a New Air Conditioner. (Also Download Worksheet To Calculate)



A new air conditioner can do more than just keep your home cool. It should also help you keep your home cool and avoid high HVAC repair costs.But people don’t think much about sizing your air conditioner when you first purchase it. By size, we mean the power levels of the system: how much cooling energy it can generate while it runs. That plays a huge part in its ultimate success or failure. Getting the right air conditioner can at times be a challenge.Whether you are choosing a window air conditioner or a central air unit, you will get the best efficiency, and therefore lower operating costs, if you choose based on the size of the area the unit must cool.

If your air conditioner is too small, it won’t be able to cool your home and will undergo all kinds of unnecessary stress to boot. If it’s too large, it will suffer stress from a different source: cycling on and off rapidly as it cools the house too quickly and subjecting the unit to severe wear and tear as well as costing you money in lost energy.

Things to consider while choosing Air Conditioning :- 

Calculate Size :-
To calculate the size, simply multiply the length times the width of the room or area to be cooled. Then, as a practical number, multiply that total times 25 BTU. This allows ample cooling, whether it is a rainy, moist day or a hot, sunny, humid day. Let’s say the room is 12 feet wide by 15 feet long. That means 12x15=180 square feet. Take the 180 sq. ft. times 25 BTU per square foot and you get the minimum BTU air conditioner you should buy. That means 180x25=4500 BTU cooling capacity is needed.
You may ask if a smaller air conditioner will work or a larger one may be better? Here’s a thought about those questions. Smaller BTU units will continually run, just trying to keep up. This will increase your electric bill and it is unlikely the unit will be able to cool the area effectively.


The location of the air conditioner :-
Before purchasing a new air conditioner, an important thing to consider is where the unit will be located. You should especially know about the installation distance, or the length between the indoor and outdoor unit. For air units between 2 to 3.5 KW, the ideal installation distance varies between 3 to 15 meters.
Also, the area where the outdoor unit is to be located should be well ventilated. There should be sufficient distance between the wall and unit that allows the air to flow easily through the system.



Variable-speed air circulation :-
Buying an air conditioner with variable-speed air circulation can offer a lot of benefits. The benefit of the variable-speed air circulation is that the motor uses about one-fifth of the energy as a regular blower. This results in reduced energy bills, as well as optimal cooling.

Sunlight exposure:-
Do you have giant picture windows with a western view? If you do, chances are you get a lot of sunshine exposure in your home. That can raise the overall temperature in your home a great deal. Sunlight exposure matters when sizing your air conditioner, which is why your technician will factor it in.
