Having the Correct Size of an Air Conditioning Unit is More Important Than You May Think

If you are thinking of getting a new air conditioning unit, you may be tempted to believe that the larger the unit the better, so you’ll buy one as big as your budget allows. Here at Petrocelli Services we have some good and bad news for you. The bad news is that biggest isn’t always best. The good news is that a smaller unit can save a you a lot of money, and not just on the purchase price.

There is a reason why it pays, literally and metaphorically, to get a proper survey of your home in order to establish what the optimum air conditioning unit for your how will be. Aside from the actual space, other factors to take into consideration include the number of south-facing windows, the number of occupants, the level of insulation, etc.

You should also be aware that air conditioning units have an optimum performance level and are designed to be used regularly and to run continually when in use. If you buy a unit that is too big for your home, three main problems will arise:

  • Your running costs will be appreciably higher than they need to be, which only adds to the unnecessary higher purchase price
  • The unit is likely to break down more often if it is keeps kicking in and out rather than gently ticking over
  • Too large a unit will cool the air too quickly in your home. As your air conditioning is designed to lower the temperature and remove internal moisture, if the temperature cools too quickly and the thermostat cuts in, you will then be left with a damp room that will also begin to smell very unpleasant.

The other mistake, of course, is getting a unit that is too small. Here your problems will be:

  • Higher running costs through lower energy efficiencies
  • Premature equipment failure
  • Inability to create a comfortable environment

Sometimes it pays to get a bit of professional advice before choosing an new air conditioner, so please do give us a call here at Petrocelli Services and we’ll be happy to advise you on the best air conditioning unit for you.
