HVAC System Capacity for Commercial Heating and Air Conditioning: What You Need to Know

The Wrong Sized Unit Means Big Problems Later On

Commercial HVAC 1

Here’s a secret: we get many new commercial customers after they have already installed a brand new HVAC system for their building. Why? Because frequently after spending all that money on the latest indoor comfort system’s bells and whistles, it often turns out the equipment they were sold is too big or too small for the space they occupy. In fact, sometimes we see commercial building owners who have spent thousands more than they had to with a system that ultimately won’t work at all for the space it was designed to serve. This sometimes requires a brand new purchase and lots of headaches in the process.

Your System Is Too Small:

Sometimes folks are talked into a smaller system than they need in a misguided attempt to save money. We’ll always support sensible spending, but beware. An undersized unit for your commercial building will translate into higher than normal energy usage, as the system has to work harder to maintain temperatures throughout. Instead of enjoying lower costs from a brand new HVAC system, customers often find they’re getting higher utility bills when they start using this equipment.

This is a huge red flag! Remember, all new heating and air conditioning systems are designed to use as little energy as possible while providing greater indoor comfort than ever before. It’s just good business, given increased environmental regulations and consumer expectations for greener fuel consumption. If you’re experiencing the opposite with your brand new system, there’s a problem. Finally, too-small HVAC will also wear out faster, as it has to work harder to keep up with demand. What seemed like a savvy, low cost option often turns into an expensive nightmare later on.

Your System Is Too Large:

Many times this happens when someone requests a “top of the line” system to match a luxurious remodel or property upgrade. Don’t be fooled. Bigger is not always better. Just as a smaller system wastes energy in trying to heat or cool a space too large for its specs, a too-large system will overdo, operating for shorter periods and cycling on and off more frequently. Furthermore, a too-large system will wear out faster, since it’s constantly starting up and shutting down.

We love new customers, but it’s disappointing to see so many folks taken advantage of by unscrupulous contractors or over-zealous HVAC salespeople. The key takeaway: don’t buy an air conditioning system that isn’t sized appropriately for your needs. Call Air-Tro today to find out more!
