Bigger is not always better. Take the case of your home’s HVAC system, for example.
One key mistake homeowners make when choosing an HVAC system is thinking that a bigger one will cool or heat the home more quickly. And on the converse side of the coin, they may also believe that a smaller system is more economical. These statements are only partially true. Take a look at some facts about hvac system size and how important it is when deciding on your next hvac system.
The fact is, an oversized HVAC system will seem like it can cool or heat an area faster, but that does not mean that you will feel comfortable or have lower utility bills. The main reason behind this is that the system satisfies the thermostat setting, but does not efficiently remove moisture in the air. An oversized system also goes into short cycling or starts and stops repeatedly. In turn, this shortens the lifespan of the system and increases energy consumption inside the home. Essentially, the same thing applies to an undersized system that must work doubly hard to keep an area warm or cool.
In short, you have to find the right size HVAC system in your home to achieve comfort, energy savings and good returns on your investment.
One key reason that homeowners buy the wrong HVAC size is that they rely only upon the square footage of the home when calculating for the general load. In getting the correct size for an HVAC system, it is important to account for a few important factors including sunlight, the duct system in the home, and heat loss and gain. In choosing an HVAC system, it is also worthwhile to consider the idea that the heating and cooling needs of a household may have changed over time.
Whether you are buying an HVAC system for your new home or replacing your current one, the new system should provide the members of your household utmost comfort for the whole year. This means that during summer, the system should not only help keep the temperature down, but also remove moisture. During winter, on the other hand, the system should effectively keep the indoor temperature warm without unnecessarily increasing your energy bills.
In order to achieve that goal, Heating and Air Contractors must utilize the Manual J Residential Load Calculation Procedure. This will entail taking into account every room in the house for calculating the load as well as air flow requirements. By doing this they will be ableto determine the right size system for your home.
Before settling for a particular system, it is also imperative to factor in the home’s duct system which contributes to the efficient circulation of air. For retrofits, consider having the ductwork in your home inspected by a reputable HVAC Company first.
