What is an Indoor Air Quality System?

Indoor air quality systems attach to your existing HVAC ductwork to filter allergens and dust as air circulates through your home, cutting down on odors too, instead of relying on standalone air purifiers in individual rooms.

Not the Purifier They Sell at the Store

When people search for an air purifier, they usually picture the machine you plug in in one room. That cleans the air in one room, and only while it's on. The one we install is different. It goes inside the duct of your central air, so it cleans the air for the whole house every time the system runs.

And in the Valley the AC runs most of the year. That means the air in your house passes through the purifier many times a day without you carrying anything from room to room.

Who It Makes Sense For

Valley dust and pollen come in on clothes and shoes and every time the door opens. A duct purifier helps cut the dust, allergens and odors that circulate through the system.

  • Homes where someone suffers during dust or pollen season.
  • Homes with pets, where hair and odors hang in the air.
  • Families who see dust on the furniture a few days after cleaning.

It isn't medicine, and we don't promise to cure allergies. If someone in your home has asthma or bad allergies, talk to their doctor. Our part is making sure the air that circulates is cleaner.

Sometimes a Better Filter Is Enough

You don't always need a purifier. Sometimes switching to a better filter does the job, and we'll tell you so. The catch is that a very dense filter can choke the airflow on an older system and make it work harder. That's why we check your equipment before recommending anything.

The purifier goes into the ductwork you already have. No new ducts, no construction in the house.

What It Needs After Install

A duct purifier isn't install and forget. Like your AC filter, it has parts that get replaced or cleaned on a schedule, depending on the model. We leave you in writing what to check and how often.

If we're already coming out to check your AC, we check the purifier on the same visit, so you don't have to remember one more appointment.

"He has been taking care of my air conditioning since 2020... Carlos is an amazing technician, he is extremely courteous, fast, honest, reliable... He doesn't try to sell you things you don't need, and he is always looking for ways to save you money."

Priscilla Ramirez

"Called about an issue we were having with our AC and he was able to resolve it over the phone at no charge. We asked if we needed any maintenance or cleaning on our unit and he was honest to tell us no."

Patricia Garza

"Carlos came on a Friday, gave us a quote and said he could install the next day. Arrived on the scheduled time and 45 minutes later we had A/C, for the quoted price. I had some other people do some work for us and the final price was well above the quoted price."

Indoor Air Quality FAQs

How is it different from a portable air purifier?

A portable one cleans the air in a single room. A duct purifier sits inside your central air system and cleans the air for the whole house every time the system runs.

Do I need new ductwork?

No. It installs in the ducts you already have, with no construction.

Does it help with dust?

Yes. It's built to cut the dust and allergens that circulate through the system, and it helps with odors too. It won't stop the dust that comes in when the door opens, but it catches it as it passes through the duct.

Can it be installed during a service visit?

Often, yes. If we're already checking or repairing your AC, we can see on the same visit whether a purifier fits your system.

Do you install them in businesses too?

Yes. In offices and waiting rooms, where a lot of people share the same air all day, a purifier in the commercial system's duct helps the same way it does in a home.
