How To Know What Size Air Conditioner To Buy

Choosing a new air conditioner can be overwhelming and confusing. Today's blog will help you understand the terminology used by HVAC contractors when making your purchase.

The following three items are of the most important:

1. Heat Load - Critical- Too small and it will not cool your home. Too large and it will cost too much to run and make your compressor work too hard. Homes "gain" heat from many sources: windows, electronics, appliances and the sun beating on your roof. The sum of these sources is known as the Heat Load, and is expressed in BTU's. 1 Ton = 12,000 BTU's. All Air Conditioning Contractors should do a heat load on your home before installing your new unit. The tonnage of the unit must be greater than the heat gain.
2. SEER Rating - Air Conditioning manufacturers are required by law to rate their equipment by energy efficiency. This rating is known as SEER or (Seasonal Energy Efficiency Rating). The higher the SEER, the more energy efficient. Higher SEER air conditioning systems are more expensive, but will make up the difference in your energy bills. You can save as much as $50 a month with the highest SEER. In the chart below you can see your yearly savings.
