"Had the entire AC/Heating system replaced. Took about 2 days because the inside equipment was in the attic. Prompt, courteous and knowledgeable. The owner DID NOT try and sell me on an upgraded system as most other HVAC companies would do. The owner only recommended what was actually required. Highly recommend this company."

"Mark and Corey were both very prompt, courteous, and professional. They presented fair pricing and superior installation on the 2 (two) HVAC systems that they supplied for my wife and I . They went the extra mile with them showing up to complete the install prior to a Hurricane headed directly at our area. I highly recommend Sensible Air Solutions for all of your needs, whether it be a full HVAC installation or HVAC service/repairs."

Heating and Air Conditioning FAQs, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.
