So, why is it crucial to get the correct size for your AC? There are four causes for this:
Comfort: Air conditioners both cool and dehumidify your home, however the latter takes longer. When you have a large air conditioning unit, it won’t operate for very long because it will cool the house quickly and then turn off before entirely finishing the job
Extra Wear and Tear: The repeated starting and stopping of your HVAC system causes it to wear out faster. As a result, the lifespan of your HVAC will be reduced. An enormous air conditioning machine only runs for a short period since it cools the house swiftly and then shuts off, as we stated in reason one. This cycle is repeated throughout the day, with far more frequent start-ups and shut-downs than a properly-sized air conditioner. Because of the increased wear and tear, you’ll most likely need additional repairs and will need to replace the unit sooner rather than later.
Cost: A big air conditioner costs more to buy, but it also costs more to run, requires more repairs, and has a shorter lifespan due to the way it operates.
Indoor Air Quality: Your indoor air quality suffers because a large air conditioner runs for shorter periods. What is the significance of this? When your air conditioner runs for shorter periods of time, it doesn’t filter the air as effectively as a properly sized unit would. This means it isn’t as effective at removing toxins from the air inside your home (think contaminants like dust mites, mold, pet dander, dead skin, allergens, viruses, and more).
You don’t want a huge air conditioning unit for your home, and you don’t want an undersized cooling unit either because it will run continually, attempting to chill the entire house, which will drive up your energy bill. A correctly sized system will chill your home much more effectively, not running too little or too much. It will save on costs on your energy bill and make your home less vulnerable to moisture problems.
So, how do you figure out what size air conditioner you need for your home? Many elements influence this decision, including the square footage of your home, the height of your ceilings, the type of insulation you have, the type of windows you have, the climate you reside in, whether you have a basement or slab, the color of your roof, and so on.
It’s important to consult an HVAC specialist to determine the appropriate system size for your home. They will undertake a Manual J load calculation, a detailed analysis of your home’s central air conditioning and heating needs based on criteria like the ones described above, to determine the appropriate size for your air conditioner.
