"Installed two Mitsubishi splits and the work was done in a professional manner by techs who knew what they were doing, were cognizant of the home interior and worked hard not to destroy any of the exterior vegetation during installation. I would without any hesitation recommend this firm to others looking for this type of an upgrade."

"Work with Tylor. His quality and customer responsiveness is top notch. I had him install 3 mini splits in our home. I originally wanted Mr Cool.. He coached me into upgrading to Mitsubishi for our area due to it’s significant quality increases vs Mr Cool and he was able to purchase and install faster and significantly cheaper than the “Home Depot” “Mr Cool” 3rd party install pricing company Highly recommend Tylor and his work"

Air Conditioning questions, answered by experts

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.
