Straight answers first

What’s going on with your air? Start here.

Choose what you’re noticing for the common signs, likely causes and how we can help. You don’t need to diagnose anything yourself.

Too much dust or airborne particles?

Dust, pollen, pet dander and other particles circulate through your home every time your system runs. Your HVAC filter is the first line of defense, but the right filter depends on your system: one that’s too restrictive can reduce airflow.

Common signs

  • Dust settles on furniture soon after cleaning.
  • Dust or dark streaks around supply vents and returns.
  • A filter that looks dirty well before its change date.
  • Allergy symptoms that seem worse indoors.

Check your filter monthly and change it when it looks dirty. A clogged filter restricts airflow and makes your system work harder.

How 365 can help

We’ll check your filter setup and system airflow, then recommend filtration that fits your system and your concerns, from a better filter to a whole-home air purifier.

Musty odors or excessive humidity?

Florida’s humidity is hard on homes. When moisture builds up indoors, it can lead to musty smells, mold growth and a clammy feel, even while the AC is running.

Common signs

  • A musty smell, especially when the AC first turns on.
  • Condensation on windows, vents or ductwork.
  • A clammy or sticky feel indoors.
  • Mold or mildew spots on vents, ceilings or in closets.

Finding the source comes first. An oversized AC, a clogged condensate drain or leaky ductwork can all add moisture.

How 365 can help

We’ll look for where the moisture is coming from and explain your options, which may include AC adjustments, whole-home dehumidification or UV treatment for the indoor coil.

Does your home’s air feel stale?

Newer homes are built tight to save energy, which also keeps cooking odors, cleaning products and other indoor pollutants inside. Without enough fresh-air exchange, air can feel stuffy and stale.

Common signs

  • Cooking or pet odors that linger.
  • Rooms that feel stuffy, especially with the doors closed.
  • Air that feels fresher as soon as you open a window.

How 365 can help

We’ll look at how air moves through your home and explain whether ventilation, better filtration or other changes make sense for your home and HVAC system.

Common problems & when to call

Warning signs and what they mean.

How do I know if my home needs indoor air quality services?

Poor indoor air quality can cause noticeable symptoms such as persistent allergies, headaches, dizziness, and respiratory issues. Other signs include excessive dust buildup, musty odors, frequent coughing, and high humidity levels that promote mold growth. If you notice these issues, scheduling indoor air quality services can help identify and resolve air pollutants in your home.

Choosing the right option

Help deciding what makes sense for your home.

What’s the best indoor air quality solution for humidity control?

To maintain balanced humidity levels, use a whole-home dehumidifier to remove excess moisture in humid climates or a humidifier to add moisture if your air is too dry. High humidity can lead to mold growth and musty odors, while dry air can cause respiratory discomfort, static electricity, and wood damage. Installing the right indoor air quality system can help regulate humidity levels for a healthier home. 

Good to know

More answers from our team.

Are whole-home air purifiers a good indoor air quality solution?

Yes, whole-home air purifiers are highly effective in removing airborne contaminants like dust, pollen, pet dander, and mold spores. Unlike portable units, they integrate with your HVAC system to filter air throughout your entire home, leading to better respiratory health and reduced allergy symptoms. Whole-home purifiers are one of the most effective indoor air quality solutions for improving air circulation and eliminating allergens. 

What are the benefits of adding a UV air sanitizer to my indoor air quality system?

UV air sanitizers use ultraviolet light to destroy airborne bacteria, viruses, and mold spores before they circulate through your home. They are especially beneficial for households with allergy sufferers, asthma patients, or those with weakened immune systems. These systems also help reduce odors and prevent mold from growing inside HVAC units and ductwork, making them a valuable addition to any indoor air quality system. 

How often should I schedule indoor air quality services for duct cleaning?

Most homes benefit from professional air duct cleaning every 3 to 5 years, but you may need it more often if you have pets, allergies, or excessive dust accumulation. Signs that indicate it’s time for duct cleaning include visible dust around vents, musty odors when your HVAC runs, and worsening allergy symptoms. Regular duct cleaning is an essential part of indoor air quality services, helping improve airflow and enhance the overall air quality in your home. 

Can indoor air quality solutions help with allergies?

Yes! Removing allergens like dust, pollen, pet dander, and mold spores from the air can significantly reduce allergy symptoms. Solutions such as HEPA air purifiers, regular duct cleaning, and humidity control create a cleaner indoor environment that minimizes airborne triggers. Improved indoor air quality services also benefit those with asthma and other respiratory conditions. 

How does ventilation affect an indoor air quality system?

Proper ventilation is essential for maintaining fresh, clean indoor air and preventing pollutants from accumulating. Poor ventilation can lead to high CO2 levels, excess moisture, and stale air. A balanced indoor air quality system brings in fresh outdoor air while filtering out dust, allergens, and airborne contaminants.

Are air purifiers part of an effective indoor air quality system?

Yes, air purifiers play a key role in an indoor air quality system by removing harmful airborne particles, bacteria, and allergens from your home. Unlike HVAC filters, which trap larger particles, air purifiers use HEPA filtration, activated carbon, and UV technology to clean the air at a microscopic level. Combining air purifiers with regular indoor air quality services provides the best protection against indoor air pollution. 

Can poor indoor air quality affect my health?

Yes, poor indoor air quality can lead to a variety of health issues, including allergies, asthma flare-ups, headaches, dizziness, fatigue, and respiratory infections. Long-term exposure to airborne pollutants like dust, mold spores, pet dander, and VOCs (volatile organic compounds) can worsen existing conditions and increase the risk of developing respiratory illnesses. Investing in indoor air quality services such as air purification, humidity control, and ventilation improvements can help protect your health. 

What is the most effective indoor air quality solution for removing odors?

To eliminate persistent odors from cooking, pets, or smoke, a combination of air purifiers with activated carbon filters, UV air sanitizers, and proper ventilation works best. Activated carbon filters absorb odors and VOCs, while UV air sanitizers neutralize bacteria and mold that cause musty smells. If your home has lingering odors, a tailored indoor air quality system can help freshen your space.
