In the HVAC world, size matters. When you need a new HVAC system, buying the right size is essential to maintaining a more energy-efficient Nazareth, Pennsylvania, home. Before buying a new system, an experienced HVAC professional will perform a Manual J calculation which takes into consideration a variety of features of your home such as number of windows, anticipated heat gain, orientation and other factors.
Oversized HVAC System
Having an oversized air conditioner sounds good in theory. A bigger unit has more cooling capacity and takes less time to cool down a house, right? Well, not exactly. Oversized systems do reach your preferred temperature more quickly, but because of this, they turn on and off repeatedly. This is a process known as “short cycling.”
Short cycling decreases your system’s efficiency and life span because it has to work harder at turning on after every shutdown. Moreover, oversized units can’t properly dehumidify a home, which could lead to moisture problems.
Undersized HVAC System
When your air conditioner is too small, it has to run longer than necessary to keep up, which makes it difficult to keep the air comfortably cool. Since an undersized unit has to work overtime, it’s more prone to breaking down and may even void your manufacturer’s warranty. You may think you can save money on a smaller unit, but you’ll pay for it in the long run.
The Goldilocks Zone
A properly sized HVAC unit is just right for your needs. HVAC professionals like to think of this as the Goldilocks Zone. Just like the story of Goldilocks and the Three Bears, it’s important to find a system that’s not too big, not too small, but just right for your home.
A system that’s just right provides the efficiency and effectiveness you should expect from your unit because it fits your home’s unique specifications. A professional HVAC technician can determine the proper system size and type best suited to your Nazareth, Pennsylvania, home.
