Coil Deep Clean
Both coils, the indoor cooling coil and the outdoor coil, rinsed fin to fin with a low-pressure cleaner made for coils. Air flows freely again and the unit stops overworking.
Where Most Of The Energy Loss Lives.
Your hotel stays fully open. Crews work in a planned sequence, and every unit goes back in the wall the same visit it comes out.
15 Min
Most rooms, start to finish, with our team on site
Fully Open
No shutdown. Your hotel keeps running normally while we work
We review your room count, unit models and occupancy so the schedule works around your guests.
Units come out of the wall sleeve onto protective tarps. Rooms stay clean and ready to sell.
Coils, pan, drain, blower, filter and grille. Every unit gets the full service, not a spray and wipe.
Units go back in, run and get checked for airflow, drainage and noise before we leave the room.
You get a room-by-room log so engineering knows exactly where every unit stands.
Dirty coils cut airflow and dehumidification, so compressors run longer and wear out sooner. Clean units mean fewer room-comfort complaints, fewer leaks under the window and fewer early replacements.

Any size. No hotel is too big or too small. We clean for independent properties with a few dozen rooms and for large portfolios with thousands of units.
Nationwide. Our crews travel to your property anywhere in the United States, and multi-property groups can schedule every location through one point of contact.
Yes. Slate is insured. Ask for proof of insurance when you request a quote and we will send it for your records.
No. Your hotel stays fully open and running while we work. We go floor by floor or room by room around your occupancy, and each unit is cleaned and reinstalled the same visit.
Most rooms are finished in 15 minutes or less. Our team pulls, cleans and reinstalls each unit in the same visit, working around vacant and checkout rooms.
Coil-safe cleaners suited to aluminum fins and copper tubing. Product safety data sheets are available on request for your engineering and housekeeping teams.
Most properties benefit from a full deep clean twice a year, and high-humidity or high-occupancy hotels can need more. We will recommend a schedule after the walkthrough.
Every property is quoted individually based on room count, unit type and access. Request a quote and we will get back to you with a plan for your building.
