Owner’s guide to HVAC Systems

101A better understanding of HVAC systems for homeowners

Your HVAC system is a core component of your home. HVAC stands for heating, ventilation and air conditioning, and by the nature of living in Florida, all three of those things are absolutely essential to your personal in-home comfort level. Yet, for being such a key to your home happiness, it is a piece of equipment that many of us know little about.

Here is a quick overview at what you need to know about your HVAC system.

First, know that a routine check up will keep your HVAC system running efficiently and could save you major dollars. In fact, just making the suggested annual check up and any needed small repairs to your HVAC can result in as much as $500 a year in energy savings alone.

Your HVAC system is actually multiple pieces of machinery placed strategically in and around your home to give your household the greatest benefit. The first part is the air handler, which is found inside the home. Secondly there is the compressor, which is the air conditioning unit. This box is typically on the outside of the home. Finally, there is a network ventilation system that connects the heater/AC and vents in your home so that when you set the thermostat, the temperature of the air in your house begins to change.

Something that every homeowner should know is the appropriate size of the AC compressor for your household. Figuring this out requires calculating the appropriate size in tons of the AC compressor in relation to the amount of BTUs it takes to cool your home.  The average Florida home will require 15-30 BTUs of cooling per square foot based upon insulation values and other factors in your home’s design. A proper load calculation requires experience and complex mathematical formulas.

You should note that there are occasionally additional factors that come into play in making this determination, and so we recommend allowing a professional HVAC contractor calculate this for you to ensure no issues. If your AC compressor is too small for your home then you will pay more in energy costs by merit of overusing it, and you will reduce the lifespan of the equipment, as well.  An oversized system will lead to improper dehumidification and excessive energy consumption, so making sure your home has the correct size system is key in keeping cool.

These simple facts cover just a few of the basic things you’ll need to know about your home’s HVAC system. If you want to know more, we recommend downloading our e-guide.
