How It Works

One Truck.
Both Coils.

Access and condition assessment

We access the indoor air handler to reach the evaporator coil. Before cleaning, the technician assesses coil condition: fin damage, mold or biological growth, and degree of fouling. If the coil is clean, we say so. If it needs cleaning, we photograph the condition before and after. Outdoor condenser access is assessed separately.

Coil wash and fin cleaning

A non-acidic coil cleaner is applied to the evaporator fin pack and allowed to dwell. The foaming action breaks down accumulated grease and debris. A gentle rinse removes the material. We use a fin comb to straighten bent fins where needed - bent fins restrict airflow the same way debris does. The condenser coil receives the same treatment from the exterior.

Drain pan and system check

The condensate drain pan sits below the evaporator coil and collects water during the cooling cycle. Algae and mold growth in the drain pan is common on coils that have not been maintained. We clear the drain line and treat the pan. Before we close the unit, airflow is checked through the system to confirm the coil is clean and the path is open.

The Coil and
the Ducts.

Your HVAC system has two distinct places where debris accumulates and restricts airflow: the ductwork and the coil. Cleaning one without the other leaves the system partially fouled. When we are already at your air handler for a duct cleaning, adding coil cleaning is a fraction of the cost of a standalone visit.

We do not promise specific efficiency gains or dollar amounts. What we can say: a coil caked in debris forces the system to run longer to move the same volume of air, and a clean coil exchanges heat more effectively than a dirty one. The rest depends on your system and your home.

What is the difference between the evaporator coil and the condenser coil?

The evaporator coil is inside your home, typically inside the air handler above the furnace or in the attic unit. It absorbs heat from the air as refrigerant circulates. The condenser coil is outside in the condenser unit and releases that heat. Both coils collect dirt and debris over time. The evaporator coil is more prone to mold growth because condensation forms on it during the cooling cycle.

How do I know if my HVAC coils need cleaning?

Common signs: the system runs longer than it used to without reaching the set temperature, the indoor unit blows air that does not feel as cold, ice forms on the indoor unit lines, or you see visible dust and debris on the coil fins when you look at the air handler. A dirty evaporator coil can also contribute to musty odors in the supply air.

Can you clean the HVAC coil at the same time as the air ducts?

Yes - and that is the recommended approach. Our crew is already at the air handler during a duct cleaning visit, with equipment connected. Adding coil cleaning during the same visit is $149 instead of the $199 standalone rate. The two services address different parts of the same system, and combining them avoids a second scheduling window.

How often should HVAC coils be cleaned?

The ACCA (Air Conditioning Contractors of America) recommends inspecting evaporator coils annually. Cleaning frequency depends on what the inspection finds: homes with pets, heavy dust, or poor air filtration may need cleaning every 1 to 2 years. Homes with good filtration and low dust may go 3 to 5 years between cleanings. We assess condition at each visit rather than pushing a fixed schedule.
