Determine the correct size air conditioner for your home.

Determine the correct size air conditioner for your home.

There are different reasons why you need to have a correctly sized air conditioner in your home. This is why it is important for you to work with an experienced HVAC contractor when you are thinking about getting a new HVAC system for your home.

Sizes of Air Conditioners

When it comes to making a choice of an air conditioner, there are several sizes available in the market. You may be able to tell the size of an air conditioning unit by checking the British Thermal Unit (BTU) ratings. The lower the ratings, the lower will be the cooling power. This means that an air conditioner that comes with a low BTU rating is best suited for small spaces. Air conditioning units with higher BTU ratings will work well in providing effective cooling for larger spaces. It is important to note that home or office spaces are not the only factor for determining the correct size of an air conditioning unit to buy. HVAC experts believe that other factors that could also play a role in determining the right size of air conditioner for your home including the age of the property and the extent of insulation in it. This is why you may find the help of an expert in air conditioning units useful in selecting the best air conditioner with the perfect BTU rating.

Why Should You Pay Special Attention to Air Conditioning Unit Size?

It is likely that you are still wondering why it is important that you buy the right-sized air conditioner for your home. The most obvious reason for this is that your home will not be adequately cooled if you decide to settle for a unit with a low BTU rating. There may be instances where a smaller air conditioning system may succeed in keeping a large space cool. But this may require the system to run far too frequently, possibly resulting in increased energy consumption. Also, if an air conditioner is too large for a place, you will still have to deal with higher energy costs. Besides the problem of higher energy costs that is associated with a system that runs too frequently than is needed, such a unit would also have a shorter lifespan. In addition, you may find yourself spending too much on repairs.

Why You May Need a Professional

Thanks to the popularity of the Internet, people can now do some things by themselves without the assistance of professionals. These days, you can easily find BTU charts online that may be used to determine the right air conditioning unit for your home. Nevertheless, you should still seek professional assistance because your home’s square footage and which BTU charts may use to estimate unit size, is not the only factor to consider when buying an air conditioner.  Call Scott-Lee Heating Company at (314) 200-0788.
