What Size Of HVAC Is Right For My House

, , , , ,


When researching for a new air conditioning unit for your home, one of the most important considerations is choosing a unit with sufficient cooling capacity and buying it through reliable HVAC contractors. Don’t know where to start? Let us take you through the steps, one by one.

Dust Off Your Math Skills & Calculate The Total Room Capacity

The first step in determining the right AC size for your home is to calculate the total volume of the air that will need to be cooled in BTU. For that, you will need to find out the exact dimensions of the living space and multiply the figures to come to the required number. The dimensions can most likely be obtained from your building plan. Once you have reached your final answer, which is most likely in cubic feet, you can then convert it to BTU using the formula that you can find on Google.

Figure Out How The Weather Changes In Your Area Annually

Keep in mind that the cooling capacity of your air conditioner changes with ambient temperature and weather conditions. If you experience a lot of heat during the summers, you will need a bigger, more powerful AC to provide you the same level of cooling. If you are located in a colder region, then you can make do with a bare minimum cooling solution, or even just a humidity regulator to get by.

Determine If The Area To Be Cooled Can Be Blocked Off For Air

When you are calculating the total air volume capacity of the area to be cooled in the first step, you are assuming that the volume will stay constant and that no air can either escape or come in from outside while the air conditioning unit is turned on. To do that, you must ensure that the space is sufficiently thermally insulated so that no heat transfer can take place to and from outside of the area.

Ensure That There Is Proper Insulation For The Walls & Ceiling

Just stopping air from leaking in or out, however, is not enough to ensure that your air conditioner performs to its optimal capacity. In order to ensure that any cooled air does not instantly lose its temperature by coming into contact with the walls or the ceiling, make sure that both of these have proper insulation.

Take The Height Of The Ceiling Into Consideration For The AC

One more thing to note when looking for an air conditioner that is the perfect size for your home is to consider how high or low your walls are. If the ceiling is too far up, the air in the room will have a difficult time traveling up to your air conditioner in order to be treated, and therefore a standing AC unit might suit you better. In case the ceiling is too low, proper convection cannot take place and therefore it is best to invest in a window type air conditioning solution.

Think About The Purpose Of The Room The AC Is Being Set Up

This is very important. If you are getting an air conditioner to cool the air in something like a kitchen, where constant flames and running appliances raise the ambient temperature to a considerable degree, you will want to invest in a bigger sized and more powerful cooling solution to provide you ideal AC cooling performance.

Make Sure There Are No Appliances That Will Hinder Function

When getting an air conditioner, make sure that there is sufficient electrical power to drive the demanding cooling circuitry, and ensure that the electrical wires are not tangled up with any other appliance and magnetic interference can cause the air conditioner to not work at its optimal temperature. Also make sure to keep it away from appliances that radiate heat like freezers and refrigerators.

Consider Any Other Features That Will Help With The Cooling

Modern air conditioners come with many value added features that allow them to improve their cooling performance. Look for things like inverter powered, pure copper fins, smart regulation etc. as these are known to offer more bang for the buck.

Remember to choose air conditioning companies Vienna you can trust when buying and servicing your HVAC or AC unit.
