Earning customers for life

Whether you’re a business owner or a building manager in Avalon Park, Florida, you’re always looking for responsible ways to cut costs. Because you know that heating and cooling can account for nearly half of your energy bill, you’ve already taken steps to manage your thermostat and cool your commercial space as efficiently as possible. Now, take a moment to consider how the size of your HVAC system affects your building and budget.

The Basics of Commercial HVAC Load Calculations

HVAC systems aren’t one-size-fits-all, nor is choosing the right size as simple as calculating a building’s square footage. If you want to avoid wasting money on a system that’s too big for your space, make sure your HVAC contractor performs the Manual J load calculations recommended by the Air Conditioning Contractors of America (ACCA). These calculations take into account everything from climate and latitude to window orientation and roof overhang. Even the number of occupants and type of window treatments can make a difference.

Many HVAC contractors have ditched these complicated calculations for a simple ratio of 1 ton per 600 square feet of space. However, because many newer homes have energy-efficient loads at or above 1,000 sq ft per ton, using this “rule of thumb” approach often results in oversized HVAC equipment. A properly sized air conditioner, for instance, should constantly run during the hottest afternoon of the year.

The Benefits of an Appropriately Sized HVAC System

An oversized HVAC system can cause several problems in a commercial building. Your system will turn on and off more frequently, wasting energy and shortening its lifespan. To make matters worse, since your air conditioner probably won’t run long enough to manage the relative humidity, your building may suffer from damp air and moisture problems. You’ll be paying extra for both installation and operation, and the added expense won’t even guarantee better comfort.

When it comes to your commercial HVAC system, ignorance isn’t blissful — it’s expensive. Call E.C. Waters at (407) 603-9144 and find out whether your HVAC system is the right size for your space.
