How to Find the Right Size A/C Unit

Proper sizing of an air conditioning unit is pivotal. If you go with a unit too big or too small, it will just not perform at the efficiency level you expect. Whether you are planning to replace an existing air conditioning unit or going with a brand new installation sizing is crucial. Our team of HVAC professionals in Jacksonville, FL is here to help you nail unit sizing to ensure peak performance!


Benefits of a Properly Sized Unit

There are many benefits to an appropriately sized air conditioning unit. The first and most apparent is lower energy costs. When you have a unit sized for your home, you will be able to rely on it to do the cooling, while not wasting energy along the way. Comfort level is also worth mentioning. A right size air conditioning unit will be able to help get your home to a comfortable temperature and keep it long-term. Finally, moisture control also is a factor. An air conditioning unit should help to reduce humidity inside of the home. Units too big or too small will not excel in that area.


Factors Leading to the Size

What are the factors that lead to the size of an air conditioning unit? The unit sizing goes above and beyond just figuring out the square footage of the home! The local climate is undoubtedly going to play a factor. Two houses of the same size, one in Florida and the other in Massachusetts will need very different air conditioning units.

The configuration of rooms inside of the home also factor into the size. A house which is wide open, versus one with many smaller rooms, will weight on unit sizing. Humidity levels of the climate, the number of doors and windows will also play a role.

It could even come down to details such as the direction your home faces, where the sun rises and sets about the home. Insulation, appliances and other detailed nuances may impact the calculation.

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 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 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
