AC coil cleaning — up to 30% more efficient cooling.
Dirty evaporator and condenser coils are one of the most common reasons an AC runs constantly but never quite cools. We clean both, safely, without damaging the delicate fins.

What Is AC Coil Cleaning?
Your air conditioner doesn't create cold air — it removes heat. That heat transfer happens at the coils, and when they're coated in dust, dirt, or grime, the whole system struggles to do its job.
AC coil cleaning clears both coils in a split system: the evaporator coil indoors, which absorbs heat from your home's air, and the condenser coil outdoors, which releases that heat outside.

Evaporator vs. Condenser Coil
Both need attention — they do opposite halves of the same job.
- Located in the air handler or on the furnace outlet side
- Absorbs heat from indoor air before it's cooled and returned
- Delicate metal fins — easy to damage without care
- Can ice over if airflow is restricted by dirt or a dirty filter
- Located in the outdoor unit, exposed to weather and debris
- Releases the heat collected indoors into the outside air
- Collects leaves, pollen, grass clippings, and dust
- Reduced airflow here forces the whole system to work harder
Signs Your Coils Need Cleaning
If a couple of these sound familiar, it's worth checking before it gets worse.
Reduced cooling even with the thermostat set low
Ice visible on the indoor evaporator coil
Higher energy bills without a clear reason
Unusual noise from the outdoor condenser unit
Visible dirt or debris on the outdoor coil fins
The home feels more humid than it used to

Our AC Coil Cleaning Process
A careful method built to protect the coil fins while clearing what's actually restricting airflow.
Inspection
We check both coils and explain what we find before starting.
Panel Removal
Access panels opened carefully to avoid bending the fins.
Loosen Debris
Soft brushes and compressed air clear loose dirt first.
Foaming Coil Cleaner
A non-corrosive solution breaks down stubborn buildup.
Rinse & Flush
Coils rinsed clean, drain pan and tube flushed clear.
Reassemble & Test
Panels reset, system restarted and checked for performance.
The Fins Are Thin, and the Cleaners Are Caustic
Coil fins are made of thin, soft metal — easy to bend or crush with the wrong brush or too much pressure from a hose. Coil cleaning solutions are also effective specifically because they're strong, which means skin and eye protection matter, and over-application can do more harm than good.
We use the right tools and the right amount of product for the coil type, so the cleaning restores efficiency without damaging what's underneath.

Benefits of Clean Coils
Utility studies have found regular coil maintenance can improve AC efficiency by as much as 30%.
Better cooling performance
Faster, more consistent cooling on hot days.
Lower energy bills
A system that isn't fighting buildup uses less power to cool.
Fewer breakdowns
Less strain on the compressor and other components.
Better air quality
Less dust and allergen buildup circulating from the coil.
Longer system life
Reduced wear extends the life of the whole unit.
How Often Should AC Coils Be Cleaned?
Ideally before the cooling season begins.
Leaves and debris build up faster outside.
Environment plays a big role in buildup speed.
A dirty filter is a common cause of a dirty evaporator coil.
Cost of AC Coil Cleaning
Pricing depends on coil accessibility and condition — a free inspection gets you a firm number before any work starts.
For a standard residential system, condition-dependent.
Every job starts with a free, no-obligation inspection.
Often discounted when paired with full HVAC cleaning.

AC Coil Cleaning FAQs
What's the difference between the evaporator and condenser coil?
The evaporator coil is indoors and absorbs heat from your home's air. The condenser coil is outdoors and releases that heat outside.
How often should AC coils be cleaned?
Once or twice a year, ideally before the cooling season — with the outdoor condenser checked more often since it's exposed to the elements.
Can dirty coils really increase my energy bill?
Yes — studies have found dirty coils can reduce system efficiency by up to 30%, which shows up directly on your utility bill.
Is it safe to clean AC coils myself?
Basic outdoor debris removal is fine, but coil cleaning solutions are caustic and the fins are easy to damage — deeper cleaning is best left to a professional.
What does ice on the coil mean?
It usually points to restricted airflow — often a dirty filter or a coil that needs cleaning.
How much does it cost?
It depends on coil accessibility and condition. A free inspection gets you a firm number first.
Do you clean the drain pan and tube too?
Yes — a clogged drain line is a common, related issue we flush and clear during the same visit.
Is this different from duct cleaning?
Yes — coil cleaning focuses on the AC's heat-exchange components. It's often bundled with duct and HVAC cleaning for a complete service.
