AC Coil & HVAC System Cleaning
The inside of your air handler is dark, damp and full of dust: ideal conditions for buildup and growth. Cleaning the coil, blower and drain system protects your air and prevents one of the most overlooked causes of water damage.
Every summer day your air conditioner pulls gallons of water out of the air. That water condenses on the evaporator coil, drips into a pan and leaves through a small drain line. When the coil is matted with dust, or the line clogs with algae and sludge, the water goes somewhere else: across the furnace, into the ceiling below an attic unit, or under the utility-room floor.
Our HVAC cleaning focuses on the wet side of the system, where restoration problems begin. We clean the evaporator coil, blower assembly and housing, clear and flush the drain pan and condensate line, and treat the components to discourage regrowth. It pairs naturally with duct cleaning, and it is often the missing step after a mold or water loss.
What our HVAC cleaning covers
Evaporator coil cleaning
Dust and biofilm removed from the indoor coil so air and water move through it properly.
Blower and housing
Blower wheel, motor housing and cabinet interior cleaned of accumulated dust.
Drain pan and condensate line
Pan cleaned, line cleared and flushed, and drainage confirmed.
Antimicrobial treatment
Products labeled for HVAC use applied to cleaned components where appropriate.
Post-loss system cleaning
Air handlers contaminated by smoke, mold or floodwater cleaned as part of the restoration.

How it works
Our process, step by step
- 01
Inspect
We open the air handler and check the coil, blower, pan and drain for buildup, growth and signs of past overflow.
- 02
Protect
The surrounding area is covered and the system is shut down safely.
- 03
Clean and flush
Components are cleaned, the pan is cleared and the condensate line is flushed until it runs freely.
- 04
Test
We restart the system, confirm drainage and airflow, and review what we found.
Omaha & Lincoln
Humid summers put the drain system to work
From June through August, air conditioners across Omaha and Lincoln run hard against humid air, which means a steady stream of condensate for months. A partially clogged line that kept up in May will overflow in July. We find the aftermath every summer as stained ceilings, wet carpet near the furnace closet and mold on the drywall behind it. An hour of cleaning in spring is far cheaper than that repair.

FAQ
AC & HVAC Cleaning questions
Straight answers to what people ask us most.
Is this the same as an HVAC tune-up?
No. A tune-up from a heating and cooling contractor checks refrigerant, electrical components and combustion. Our service is cleaning and decontamination of the air handler, coil and drain system. We do not repair or service the mechanical or refrigerant side of your equipment.
How do I know if my condensate line is clogged?
Water in the secondary pan, water on the floor near the furnace, a tripped float switch that shuts the AC off, or a musty smell near the unit are the usual signs.
Should I have this done with duct cleaning?
It makes sense to do them together. Cleaning the ducts and leaving a dirty coil and blower means the system starts re-contaminating the ductwork right away.
My AC leaked and damaged the ceiling. Can you handle all of it?
Yes. We dry the structure, clean the air handler and drain system, and repair the drywall, paint and flooring.
