Why Proper Sizing for Commercial HVAC Systems Is Important

Having an uncomfortable business space impacts you, your business and your customers. Whether you are sizing an HVAC system for your own business or a commercial space with multiple businesses, it’s very important to install a correctly-sized HVAC system to achieve the comfort level you need in each space. Using just any company for your commercial HVAC services in Orange Park, FL can put you and your business at risk, so call the professionals you can count on: J&W Heating and Air.

What Happens with the Wrong-Sized HVAC System?

There are only two ways to go wrong when sizing an HVAC system: too big or too small. When an HVAC system is too small for your commercial space, it won’t heat or cool adequately. This can result in energy efficiency issues because the system will be running constantly to try and reach the set temperature(s), as well as potential premature aging.

A system that is too large presents a couple of different problems. First, operating an oversized HVAC system can cause a problem called short-cycling: the system turns on and off too frequently. The reason short-cycling occurs is that an oversized system will heat or cool the air too quickly; as such, the system achieves the set temperature too fast, so the system shuts off. The space will then cool down or warm up quickly, which triggers the cycle to re-start.

A second problem that can develop with a system that is too large is poor humidity control. When a space cools too fast, the HVAC system does not have a chance to properly remove the humidity in the air. This results in a cool, clammy feeling during the warm months.

Lastly, energy efficiency is decreased because the short-cycling over-uses energy due to constant start-up.

One of the best ways to ensure that you install a commercial HVAC system that fits your business space is by hiring trained commercial specialists: this is where J&W Heating and Air comes in.

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company again.read more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two men.read more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
