Professional Ceiling Concealed AC Cleaning Service

Step 1: Safety & Site Preparation
We lay down heavy-duty plastic sheeting and waterproof drop cloths. Since your unit sits inside the ceiling cavity, water can easily leak onto your furniture or flooring if done incorrectly. Our technicians test the condensate drain function before touching the unit.

Step 2: Access Panel Removal & Component Extraction
We carefully remove the access panel (or the entire return air grille assembly). Unlike inexperienced cleaners, we label every screw and wire connector. We then safely remove the centrifugal blower wheel and the drain pan—two parts that are never cleaned during a basic service.

Step 3: Dry Vacuuming of the Cavity
Using a HEPA-filter vacuum, we remove loose debris from the concealed box, insulation lining, and motor housing. This prevents mud formation when we apply water later.

Step 4: Chemical Coating & Degreasing
We apply a non-acidic, foaming coil cleaner specifically designed for aluminum fins. For the blower wheel, we use a heavy-duty degreaser that breaks down the greasy dust amalgam (the sticky brown layer unique to kitchen or high-humidity environments).

Step 5: High-Pressure Steam & Water Jet Cleaning
Low-pressure washing pushes dirt around. We use a pressurized steam lance (no electricity to the unit—safely isolated) to blast away 99% of biofilm, mold, and caked-on dust from:

• Evaporator coil fins
• Blower wheel vanes (every single slot)
• The internal walls of the AHU (Air Handling Unit)
• The condensate drain pan (removed and scrubbed in our outdoor wash station)

Step 6: Anti-Bacterial & Anti-Algae Sanitization
Once cleaned and rinsed, we spray an EPA-registered sanitizer that kills mold, mildew, and legionella bacteria. A separate algae tablet is placed in the drain pan to prevent future clogs for up to 6 months.

Step 7: Reassembly, Air Balancing & Performance Test
We reassemble all components, seal the access panel with UV-resistant HVAC tape (to stop ceiling air leakage), and measure the temperature differential (Delta T) at the supply and return vents. You will receive a digital report showing “Before” photos (dirty components) and “After” photos (spotless internals).

5 Signs Your Ceiling Concealed AC Needs Immediate Cleaning

You cannot see the dirt, but your home and health will show the symptoms. Book a Ceiling Concealed AC Cleaning immediately if you notice:

• Musty or “Dirty Sock” Odor: This is biological growth on the wet evaporator coil or drain pan.
• Weak Airflow: The system runs for hours, but the vents barely push out air.
• Water Stains on the Ceiling: A sure sign of a blocked condensate drain inside the concealed unit.
• Rising Electricity Bills: A dirty coil forces the compressor to run 40% longer to achieve the same cooling.
• Allergy Flare-Ups: Sneezing, itchy eyes, or coughing that worsens when the AC turns on.

The Cost of Neglect vs. The Value of Professional Cleaning
Many homeowners delay ceiling concealed AC cleaning because they assume it is expensive. Let us compare:

Issue Cost of Neglect Professional Cleaning

• Energy Efficiency $50-$100 extra per month in summer Restores original EER rating
• Compressor Failure $1,500 – $3,500 replacement Prevents high-head pressure failures
• Ceiling Water Damage $2,000 – $5,000 repair (mold remediation + painting) $0 (clean drain pan prevents clogs)
• AC Lifespan 5-7 years (premature death) 12-15 years (like-new operation)
  A single professional cleaning every 6-12 months costs less than one month of wasted electricity. You are not spending money; you are saving your asset.

Why Choose Us for Ceiling Concealed AC Cleaning?

Not every HVAC company offers true concealed unit cleaning. Most “technicians” will spray coil cleaner through the return grille without removing the blower wheel. That is a scam. Here is what makes us different:

• Certified NADCA Technicians: We follow air systems cleaning standards, not guesswork.
• No Hidden Damage: We use non-toxic chemicals safe for aluminum, copper, and plastic. No bent fins, no dented coils.
• 100% Dry Guarantee: If we get a single drop of water on your floor or furniture, the service is free.
• Photo Evidence: We hand you an iPad showing dirty blower wheels vs. clean ones before we collect payment.
• We Clean Everything: Return air plenum, supply air plenum, insulation lining, and even the inside of the flexible duct collar.
