Coil Cleaning Lititz (2024)

FAQs

How much should a coil cleaning cost? ›

Most HVAC professionals recommend AC coil cleaning once or twice a year. If dust and dirt build up on the coils, major problems can occur. The AC coil cleaning cost is around $100 to $400 as of 2024, according to Homeguide (for an evaporator coil), and up to $700 to remove and clean the coil.

Cleaning AC units reduces electricity bills.

A product like Air Conditioning Coil Cleaner removes counterproductive dirt and oxidation on air conditioning coils. When fins and coils are clean, air circulates more fully and AC systems operate and cool more efficiently, reducing the unit's power consumption.

Using a hose, spray water onto the coils to remove dirt and dust. After the waiting period is over, use your hose to rinse the coils clean. For best results, start by spraying the AC unit from the inside out, starting at the top of the unit and working your way down.

Never use acid-type cleaners indoors. Always spray downwind when cleaning outdoor condenser coils. Use a gentle hose nozzle to rinse off chemical cleaners, never a high-powered pressure washer.

Ineffective cooling.

If you notice your home isn't as cool as it used to be, this could be a sign of a dirty coil. Since a dirty coil prevents your unit from working properly, you might notice that your living space is often warm or that it takes a long time to cool down.

It is recommended to perform an annual cleaning of your AC unit's coil, although if the unit encounters substantial amounts of dirt, dust or moisture more frequently, it may be necessary to clean it quarterly.

Wait 5 minutes after spraying the outside of the fins with a coil cleaner or a detergent/water mixture. Rinse the coil cleaner gently with water using a garden sprayer. Spraying the fan motor is not a good idea. Reassemble the system and turn on the main power switch.

Wait at least 30 to 60 minutes for the unit to dry. Water and dampness can interfere with the unit's operation and cause electrical components to short circuit.

Your unit seems to be running longer for no reason.

When the AC coils are dirty, the unit has to work longer and harder to cool the inside space. You'll hear the blower running and feel air coming out of the ducts for a long period of time.

Nevertheless, you can keep your coils in good shape by mixing white vinegar and water in a spray bottle and spraying the mixture onto the coils. If your condenser coils are greasy, you can also try adding a tablespoon of baking soda to the mix.

Can I use Dawn dish soap on my AC coils? ›

While Dawn dish soap is a versatile cleaning agent, it's not recommended for cleaning AC coils due to its chemical composition. Household cleaners like Dawn may not effectively remove stubborn buildup and could potentially harm the coils or other components of the system.

Spray the coils down with Simple Green All-Purpose Cleaner.

Let the Simple Green sit 10-15 minutes to penetrate heavier soils, and then hose it down again. After the coil cleaner has dripped off the coils, examine the coil surfaces for any areas that may need another application, and repeat this step as necessary.

Cleaning AC coils costs anywhere from $75 to $700, or an average of $125 per coil. Dirt, dust and pet hair tend to accumulate on both your condenser and evaporator coils, and the buildup can cause major issues down the line—especially during a heatwave.

When cleaning your outdoor coil, the contractor will likely clear away any surface debris by hand or with a special fin brush. Then, they will follow up by applying the commercial cleaner, and rinsing the coil with water depending on the cleaner instructions and manufacturer's recommendations.

If you work your way through coils at an alarming rate, it may well be worth cleaning them. But if you use MTL coils and vape at a low wattage, each coil could last you for a couple of weeks. In this case, it probably isn't worth making the effort to clean them as your expenditure on coils will be limited anyway.

Clean your coil with a garden hose with an adjustable nozzle. Set the water pattern to a wider, gentler setting like “Flat” or “Shower.” Do not use the “Spray” setting. Begin at the bottom of the unit and slowly wash a few inches across, spraying left and right across the coil.
