Tested, But Still No Solution?

Plenty of companies offer indoor air quality testing. Lab tests, mold assessors, air quality monitors. They hand you a report full of numbers and a list of products to buy: a better filter, a UV light, an air purifier, more fresh air.

Then the problem comes back. Testing tells you what’s in your air. It doesn’t tell you why it’s there, or how to stop it.

We do both. We test your air, find the cause, fix it at the source and test again to prove it worked.

Your AC Either Cleans the Air in Your Home or Pollutes It

Your air conditioner is the only thing in your house that pulls in, conditions and sends back out all of the air, all day long. Nearly every breath your family takes inside has been through it.

When it’s designed and installed correctly, it traps what’s floating in the air, controls the moisture and keeps the whole house clean and comfortable. When it isn’t, it does the opposite: it spreads dust, allergens, chemical pollutants and mold spores to every room.

That’s why real indoor air quality solutions aren’t a gadget you add. They come from an AC system that’s designed, installed and set up to clean your air.

Fix the system, and you fix the air.

Signs of Poor Indoor Air Quality

Poor indoor air quality doesn’t always look like anything. More often, you feel it. Watch for:

Some people call it sick house syndrome. Whatever the name, these are symptoms. The cause is almost always in how air moves through your home and your AC system, and that’s what we find.

Why a Whole House Air Purifier, Better Filter or UV Light Won’t Fix It on Its Own

When the air tests poorly, the usual answer is to add a product: a thicker filter, a UV light, a whole house air purifier. Each one treats a symptom. None of them fixes why the air got dirty in the first place.

Worse, adding a product to a system that wasn’t designed for it can create a new problem. A filter that’s too restrictive chokes the airflow. Less air moving through the system means less moisture removed, higher humidity, and more mold and chemical pollutants in the air. One problem solved, another created.

Filters and UV lights have their place. We use the right ones, but only as part of a system that’s designed to work with them.

Alex’s Casselberry Home: Airborne Particles Down 58%

Alex’s Before and After Readings

AirAdvice monitor readings from Alex's Casselberry home: airborne particles averaged 15.1 before the new system and 6.3 after, within the safe range

The problem: Airborne particles (dust and allergens) in Alex’s home averaged 15.1, above the recommended level of 10, and the house averaged 78°.

What we did: We replaced his system with one designed for his home, with the correct filtration and humidity control, and monitored the air before and after with our AirAdvice monitor.

The result: Particles dropped 58% to an average of 6.3, within the recommended range. The house now averages about 73° with humidity around 44%, and formaldehyde, chemical pollutants (VOCs) and carbon monoxide are all within the recommended range.

Averages from AirAdvice monitoring. Recommended levels are those listed in the AirAdvice report, based on EPA and American Lung Association guidance.

Kristen’s Home: From Two Allergy Shots a Week to None

Watch Kristen’s Story

The problem: Kristen was getting two allergy shots a week from her doctor.

What we did: We found mold in her AC system, the system that was moving the air through her whole home, and fixed it at the source.

The result: Kristen went from two allergy shots a week to none. And her husband, who thought he felt fine, noticed he coughs about 90% less in the house.

This is general information, not medical advice. If someone in your home has symptoms, talk to your doctor.

Why More Outside Air Isn’t the Answer in Florida

One of the most common recommendations for poor indoor air quality is to bring in more fresh air from outside. In a dry climate, that can help. In Florida, outside air is hot and loaded with moisture for most of the year.

Bring more of it into your home without controlling that moisture, and your indoor humidity goes up. High humidity feeds mold, and chemical pollutants like formaldehyde are released faster in warm, humid air.

In Florida, fresh air has to be brought in and dried the right way, as part of a system designed for your home. Otherwise you’re trading one problem for another.

How Our Indoor Air Quality Testing & Solutions Work

  1. We test your air. We place an AirAdvice monitor in your home for several days to measure airborne particles, chemical pollutants (VOCs), formaldehyde, carbon dioxide, carbon monoxide, temperature and humidity.
  2. We find the cause. We look at your AC system, ductwork and home to find where the contamination is coming from and why it stays.
  3. We show you what we found. In plain language, with the numbers, before any work begins.
  4. We fix it at the source. Correct system design and sizing, airflow, humidity control and the right filtration for your system.
  5. We test again. A second test proves your air is within the recommended range, and you get the results in writing.

VOC Testing

VOCs are chemicals released into the air by paint, cleaners, new furniture, flooring and building materials. They can cause headaches, irritation and that “something’s off” feeling at home. We measure VOC levels with an AirAdvice indoor air quality meter, find the source and fix it, then retest to prove it worked.

Carbon Dioxide (CO2) Testing

High CO2 means your home isn’t getting enough fresh air. It can leave you tired, foggy and stuffy, especially in tightly sealed homes. Our AirAdvice meter measures CO2 room by room, and we correct the cause.

Air Purification

An air purifier helps when it’s part of the fix, not a cover for it. Most indoor air problems are created or spread by the AC system itself. We correct that first, then recommend purification only when your test results show it will help.

Fresh Air Ventilation

Modern homes are sealed tight to save energy, which can trap stale air, CO2 and moisture inside. Fresh air ventilation brings in outside air in a controlled way, without adding Florida humidity. We design it to fit your home and your AC system.

Clean Air Comes From a System That Works Together

Indoor air quality isn’t one fix. It’s every part of your system doing its job.

Humidity Control

Dry air is clean air. Humidity held between 50–55% keeps mold and chemical pollutants in check.

Indoor Air Quality Questions We Hear Most

How do I improve indoor air quality in my home?

Start with the basics: change your filter on schedule, run your bathroom and kitchen exhaust fans, and keep humidity between about 40% and 55%. If the problem keeps coming back, the cause is usually in your AC system: how it was designed, sized and installed, and how air moves through it. That’s what we find and fix.

What’s the difference between indoor air quality testing and a solution?

Testing measures what’s in your air. A solution fixes why it’s there. We do both, then test again to prove the fix worked.

Should I buy an air purifier or test my air first?

Test first. An air purifier, filter or UV device may address one part of an indoor air problem, but testing shows what’s actually in your air and what’s contributing to it. We perform indoor air quality testing before recommending anything, so the fix matches the problem in your home.

How much does indoor air quality testing cost?

It depends on the size of your home and what we’re testing for. Call us and we’ll give you the price before we start.

Do whole house air purifiers work?

They can remove some particles, but they don’t fix the cause. If your AC system is spreading dust, moisture or mold, a purifier is fighting a problem that keeps coming back. Added to a system that wasn’t designed for it, it can also reduce airflow and raise humidity.

How do I reduce VOCs and formaldehyde in my home?

Limit the sources you can, like harsh cleaners, paints and new furniture, and keep humidity under control, since chemical pollutants are released faster in warm, humid air. Then make sure your AC system is filtering and conditioning the air correctly.

What causes a musty smell in my house?

Usually moisture and mold, often inside the AC system or ductwork. It’s a sign something in the design, installation or airflow isn’t right, and it should be checked.

Should I bring in more fresh air to improve my air quality?

Not without controlling its moisture. In Florida, uncontrolled outside air raises indoor humidity, which feeds mold and chemical pollutants. Fresh air has to be brought in and dried correctly, as part of a system designed for your home.

Do you guarantee the results?

Yes. After we fix it, we retest. If your air doesn’t test within the recommended range, we keep working until it does, in writing.
