Homeowners will hear a lot about HVAC efficiency when dealing with the repair, maintenance, tune-ups, purchase, installation, and replacement of heating and air conditioning systems; but when it comes down to it, what truly constitutes efficiency, and what features are key to an HVAC system’s performance and efficiency? Today we will be looking deeper into HVAC system efficiency, and explaining all of the modern features that work towards higher energy, heating, and cooling efficiency.
HVAC Ductwork Efficiency
Many homeowners do not realize how much the ductwork of your HVAC system plays a role in both high efficiency and a lacking of efficiency. While many of the modern, technical advances in heating and cooling systems that have led to higher efficiency are in-fat housed within the mechanics of the unit itself, many homeowners forget that the most common place in a home or business where energy efficiency and heating and cooling efficiency is lost is within the ductwork.
Think about it – the treated air (warmed or cooled) makes a journey from the central unit to the various rooms and zones in a home. While it is inevitable that the air will lose a few degrees in either direction during this journey, some less insulated ductwork systems or incorrectly sized ducts can a detrimental amount of heated or cooled air, leading to a drastic reduction in efficiency.
Another HVAC system feature that many forget about or never even consider when it comes to efficiency is the Return Air feature. A home is more or less hermetically sealed (airtight) space, this means that if you pump air into the space, there must be an equal amount of air leaving that same space, in order to keep the air pressure even and the HVAC system running efficiently. If more air is being pumped into the space than is leaving, you run the risk of breaking seals around ducts, windows, doors and even in the HVAC system itself. Conversely, if more air is leaving into the return-air than is being pumped into the space you will get a slight suctioning effect that drops HVAC efficiency and can be hard on system components.
As you can see, these two components of heating and air conditioning systems may often be forgotten or taken for granted, but they play a strong and integral part in assuring that ALL of your systems components work together in a cohesive strategy for maximum comfort and maximum efficiency.
