Choosing The Right Air Conditioning System

Published August 2013 by

If indoor air quality and temperature control is a major concern of yours, an air conditioning system is likely to be the ideal solution to your problem. If you already have a boiler or furnace you can install a central air conditioning unit to cool your house. These cooling and ventilation units are energy-efficient (which means big savings for you) and they require very little care and maintenance. Only periodic cleaning is necessary, to prevent dust and debris from clogging the unit. If you’re interested in having an air conditiong system installed in your own home, you need to figure out which unit is right for you, and there are a few particular points to consider.

Size of the Unit & Space Available

The size of unit you need is dependent on the size of building it will be cooling For a smaller home you would need a standard sized model, while a large commercial property might require a larger unit or possibly even multiple units. Smaller units tend to be less expensive and a bit simpler. If you’re looking to get a higher quality unit with more features and other options, the larger units might be your best bet.

Energy Star provides a handy chart to help you calculate what capacity air conditioner you need to cool your home. To find the proper capacity air conditioner you need to calculate the square footage of your home that you intend to cool. But that’s not the only factor. The SF Gate recommends these tips for re-calcuating BTUs:

  • When calculating total square footage of a home, exclude areas that are not cooled, such as your garage or basement.
  • If your room or home is shaded, reduce BTU capacity by 10 percent.
  • If your room or home receives full sun, increase BTU capacity by 10 percent.
  • If more than 2 people occupy the room, add 600 BTU per person.
  • If the air conditioner is to be placed in the kitchen, add 4,000 BTUs to the necessary capacity.


Although it’s important, In order to ensure you’re getting a quality unit, price should not be the primary factor in your choice. Although these systems come with a high initial cost, long term cost savings of a pricier energy efficient unit make them a sound investment in the future of your home. Given the utility savings alone, the cost of the system is likely to balance out within a year over options with a lower initial cost. Not to mention that pricier systems tend to be better quality and last a lot longer.


Another aspect to consider when shopping for an air conditioning system is the brand. Major reputable brands include Carrier, Trane, and York. These brands offer a large selection of HVAC units, as well as some of the best warranties, and therefore make them a good place to start your search for the right unit. Furthermore, it is important to select a certified energy efficient system with positive reviews when selecting your air conditioning unit. Certain models have a higher efficiency than others, making them a better investment, both short and long term, in both the environment and your wallet.

Shopping for an air conditioning system doesn’t have to be a huge hassle, and you can get help if you’re not sure which is right for you. If you need help deciding on the right HVAC system for your home, you should consult with an HVAC specialist in Sacramento. They’ll help you find the best unit at the best price for all your air conditioning needs.
