Breathe easier at home. Costa Mechanical installs Fresh-Aire UV, high-efficiency filtration, whole-home dehumidification and duct sealing across Lee, Collier and Charlotte counties.
In Southwest Florida, the air inside your home can be working against you. Months of high humidity feed mold and mildew, our sealed-up, air-conditioned houses trap allergens and odors, and the same coils that cool your home become a breeding ground for biofilm. Costa Mechanical & Refrigeration designs indoor air quality systems that tackle all of it — so the air you breathe at home is cleaner, drier and healthier.
We're a family-owned, veteran-operated company, and we approach air quality the way we approach everything: diagnose the real problem, recommend only what helps, and price it up front. Most homes don't need every product on the shelf — they need the right two or three working together.
We build a layered system from proven components, sized to your home and your concerns:
Humidity is the root of most indoor air complaints in this part of the state. When relative humidity climbs above the mid-50s, mold spores activate, dust mites multiply, and that musty smell creeps into closets and around the air handler. Your AC pulls out some moisture as it cools, but during milder weather it doesn't run long enough to keep up. A whole-home dehumidifier holds your home in the healthy 45–55% range around the clock — which also makes the same thermostat setting feel cooler, so you stay comfortable while protecting your home.
Anyone breathes easier with better air, but some households feel it immediately: allergy and asthma sufferers who react to pollen and dust, pet owners fighting dander and odor, and families with a new baby or an elderly parent at home. If anyone in your house wakes up stuffy, if rooms smell musty, or if you dust constantly, your indoor air is telling you something.
A plug-in purifier or a closet dehumidifier only treats one room and needs constant babysitting. Whole-home systems install into your existing ductwork and treat every room every time the air moves — quietly, automatically, and without the clutter. They cost more up front but do far more, and we'll lay out both paths so you can choose. Keeping the system clean matters too, which is why air quality pairs naturally with an AC maintenance plan and professional duct & vent cleaning.
Yes. A Fresh-Aire UV system installed at the indoor coil targets the mold, mildew and biofilm that thrive on damp Florida coils — the stuff that causes musty odors and gets blown through your home. By keeping the coil and drain pan clean, UV also helps your system run more efficiently. It works best as part of a layered approach alongside good filtration.
Your AC removes some humidity as it cools, but in Southwest Florida that's often not enough — especially in shoulder seasons when the system runs less. A whole-home dehumidifier integrated with your HVAC holds your home at a healthy 45–55% relative humidity, which discourages mold, protects furnishings and makes the same temperature feel cooler and more comfortable.
They can make a real difference. High-efficiency filtration captures the pollen, dust and pet dander that trigger symptoms, UV treatment cuts down on mold and microbial growth, and controlling humidity discourages dust mites and mold. People with allergies, asthma, pets, or a new baby in the home tend to notice the improvement most.
It's more affordable than most people expect, and we offer options at different price points — from a simple high-efficiency filter upgrade to a full package of UV, dehumidification and duct sealing. We'll give you up-front pricing and recommend only what fits your home and budget, with Okinus financing available for larger projects.
