What gets asked before we open a unit

What is AC Bio Clean?

Probiotic foam on the coil while the unit is running. It clings, eats biofilm, and keeps working about 90 days. Not a chemical rinse. Not a filter change sold as PM.

How is this different from a chemical clean?

A chemical clean is a rinse and a shutdown. It hits the face of the coil. Biofilm in the pack stays. We foam a live coil. No rinse. Guest rooms, the dining room, and the lobby stay in service.

Does the unit stay on?

Yes. Foam on. Unit on. That is the point. Occupancy does not stop for the clean or for the assessment.

Is it safe for guests and staff?

Yes. The building stays open. We are not running a chemical wash through occupied guest rooms or a dining room.

What equipment do you treat?

• Guest-room coils
• Ceiling AHUs — no cut-outs to reach the coil
• RTUs
• Kitchen and dining units
• Walk-ins and prep coolers
• Common-area and zone coils

A room, an AHU, and a rooftop are not quoted as one line.

What is the free on-site coil assessment?

You pick 1–2 units that are the problem. We photograph the coil. We run a foam test so you see the restriction. Same day you get the plan and the quote.

Full service or product + custom PM?

Hotels choose after they see the coil.

Full service: we take the list. Engineering does not run a spray program.

Product + custom PM: we supply the product, write the PM, train engineering. One add — spray the coil at filter change. A brand can hand that playbook to the next hotel.

Restaurants and commercial buildings are full service.

Can my engineers do it?

Only if you pick product + custom PM. Full service: hand us the list. We teach one simple add, not a new career path.

How long are you on property?

Assessment: 1–2 units. A room coil is minutes. Five AHUs at Hampton Brickell took about 30 minutes. Used to be a 4–5 hour chemical wash. A 357-room Beach hotel is scheduled around occupancy.

How often?

Quarterly. Foam keeps working about 90 days. Filters and UV do not eat biofilm. Skip a quarter and the pack loads up again in this climate.

What if the coil is already packed?

That is what the assessment is for. We show you the face of the coil. Heavily fouled units get the first clean on the list. Then they go on the quarter.

What does it cost?

You see the number after we open 1–2 units. A neglected 20-ton and a closet unit are not the same job. After the first service, you decide. The visit does not lock a year.

Will this cut OOO rooms and smell tickets?

Air and smell change when airflow is back. OOO rooms come off the board when that unit is done. That is why we start with the problem units, not a brochure.

Does it keep the compressor from working so hard?

A dirty coil is a restriction. The fan and the compressor run longer to hit set point. Clean the coil and the unit can do the job it was sized for. Verdant data from treated vs untreated rooms on the same floor is on the Verdant case.

What if the first clean misses?

We come back on that unit. Written terms: guarantee page.

Who is this for?

Hotel GMs and Directors of Engineering. Restaurant owners. Building managers in South Florida. Not a condo-neighbor rate. Not a one-time hose-down with no return visit.

How do we start?

Book the assessment. Phone (305) 422-1811. Have 1–2 problem units ready.
