Humidity Control and Your HVAC System

Posted by

Jacksonville is not known for its dry, arid climate – quite the opposite, in fact. Our proximity to the water and our frequent storms bring us high humidity year-round. The humidity can really be a drag in the summer when the high moisture levels leave us feeling sticky, hot, and a little frustrated with the sunny season.

Humidity control is one of the advantages of central air conditioning. If you’re having trouble with humidity in your house, read on to see how you can improve your system’s functionality.

How Your HVAC System Controls Humidity

Humidity control as it pertains to your home HVAC system relies on a very simple principle: cooler air cannot hold as much moisture as warmer air. By cooling your home through an air conditioner, you remove the potential for moisture in the air that circulates around the house.

All air conditioners have some capacity to remove humidity from the air. Smaller units do so with less efficiency than larger units, though it may surprise you to learn that larger units do not necessarily offer the best humidity control for your home. In these situations, it is not the size that matters, but how the air conditioner functions that provides the best outcome.

Drafting Variable-Speed Fans Onto Your HVAC Team

If cooler air holds less moisture, your first instinct might be to install the biggest air conditioner you can order. This will offer fewer benefits than you would expect. While larger central units do provide greater humidity control, they only do so when they are running.

An oversized air conditioner will need to turn on less frequently than a smaller unit. This allows moisture to creep back into the air and linger. The better option is a correctly sized unit with a variable-speed fan.

A variable-speed fan allows your air conditioner to run continually. When the air is cool, it slows down to a lower, power-saving speed, and only kicks up to a higher rate when it needs more energy to bring the temperature lower. This allows a constant source of humidity control, as well as more consistent cool temperatures for you to enjoy.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

-Linda Ackley

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Very prompt, professional, courteous, and cleaned up after repair. Had water line break in my front yard and no pressure. Very pleased and would highly recommend Snyder for all your plumbing, and AC needs. Thank you for making a rough morning get better with ease and professionalism.

-Chuck Jr.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
