Case Study: The Nocatee 'Hot Room' Hero
In a 3,200 sq. ft. modern home, a bonus room over the garage stayed 8 degrees warmer than the house. We installed a single-zone inverter system with a surgical 3-inch wall penetration and painted Line-Hide covers. The office now stays at a perfect 72°F while lowering the overall home energy usage.

The Pro’s Advice
“Protect your ductless investment in the Jacksonville humidity.”
The Two-Week Filter Rule: Rinse your washable filters every two weeks. Clogged screens are the #1 cause of JEA bill spikes.
Bio-Film Defense: Once a year, have us flush your drain line. Algae slime in our 90% humidity causes 90% of indoor leaks.
Salt Spray Rinse: Coastal residents should gently rinse the outdoor unit with fresh water monthly to remove salt buildup.
Use 'Dry Mode': On 75-degree humid days, run 'Dry Mode' to focus on dehumidification without over-cooling the room.

Questions?
“Everything you need to know about keeping your home comfortable.”
Yes. A 'Whole-Home Retrofit' allows you to scrap leaky ductwork entirely, providing dedicated temperature control for every room.
Not with Always On Air. We use architectural Line-Hide covers that can be painted to match your home’s exterior and meet strict HOA standards.
Absolutely. These are high-efficiency heat pumps that provide warmth even when temps drop into the 30s or 20s, much more efficiently than electric strips.
Most single-zone installations are completed in one day. Complex multi-zone whole-home projects typically take 2 to 3 days.
Yes. Under the IRA, high-efficiency heat pump installations can qualify for federal tax credits up to $2,000. We provide all necessary AHRI certificates.
