When your air conditioner is running but your home never quite reaches the temperature you set, dirty coils are often the reason. Over time, buildup on your AC coils forces your system to work harder than it should, driving up energy costs and shortening the life of your equipment. At Ellis AC & Furnace Repair, we have been helping Dallas homeowners keep their systems clean and running efficiently since 1975. Coil cleaning is one of the most straightforward ways to protect your investment and maintain reliable comfort through the long Texas summers.

What Your Neighbors Are Saying About Us

Replaced the old with the new. I got a fantastic price on the new heat pump system. The installation went really smoothly, and it is working great. I like this company.

We’ve been clients of Ellis for 20+ years at our home and office. Yesterday we woke to no heat, of course with the coldest temps of the year just 2 days away, we called Ellis.

Ellis air installed an infinity heat pump system at our home 15 years ago. Best thing we have ever done. It has preformed beautifully over the years and is still going strong thanks to Ellis Air.

Jesse came for my semi annual heating checkup. He was prompt, calling ahead to say he was on his way. He was very thorough and explained everything he did.

I highly recommend Ellis Air & Heat. Larry Hatley service Technician came out and checked the unit out. Larry is one of the most pleasant, delightful person to deal with.

The Role AC Coils Play in Keeping Your Home Cool

Your air conditioning system relies on two sets of coils to move heat out of your home. The evaporator coils, located inside your air handler, absorb heat and humidity from the air as it passes over them. The condenser coils, located in the outdoor unit, release that heat outside. Together, these components are what make the cooling process possible.

When either set of coils becomes coated in dust, debris, or grime, heat transfer is compromised. The system has to run longer cycles to achieve the same result, which puts unnecessary strain on the compressor and other components. In Dallas, where air conditioners often run for eight or more months out of the year, that kind of sustained stress adds up quickly.

Warning Signs Your AC Coils Are Due for a Cleaning

Dirty coils do not always announce themselves in obvious ways, but there are signs that point to the problem if you know what to look for.

Your home takes longer than usual to cool down, even when the system is running continuously.
Your energy bills have increased without a clear explanation.
The air coming from your vents feels warmer or less powerful than it should.
Ice has formed on your indoor unit or refrigerant lines.
Your system is short-cycling, meaning it turns on and off more frequently than normal.
There is a musty or stale odor when the system is running.

If any of these sound familiar, a coil cleaning is a good place to start before assuming a more serious repair is needed.

What Leads to Buildup on Your AC Coils

In a climate like Dallas, coils tend to accumulate buildup faster than homeowners expect. High humidity causes dust and airborne particles to stick more readily to coil surfaces. Pollen counts in North Texas are consistently high throughout spring and fall, and that pollen works its way into the system through the air intake. Outdoor condenser coils also collect cottonwood, grass clippings, and debris stirred up by wind.

Inside the home, pet hair, cooking grease, and household dust all contribute to buildup on the evaporator coils over time. A clogged or low-quality air filter accelerates this process significantly. Even with routine filter changes, professional coil cleaning is still recommended because filters do not catch everything.

How We Clean AC Coils the Right Way

Coil cleaning done poorly can damage the fins, introduce moisture in the wrong places, or leave residue that causes more buildup down the road. Our technicians take a careful, thorough approach from start to finish.

We begin by inspecting both the evaporator and condenser coils to assess the level of buildup and identify any existing damage. The system is powered down safely before any cleaning begins. We use professional-grade coil cleaners appropriate for the coil type, applying them in a way that loosens debris without harming the fins or surrounding components. Stubborn buildup is addressed with low-pressure rinsing techniques that protect the integrity of the coil. Before we leave, we confirm the system is operating correctly and that airflow and temperatures are where they should be.

What Routine Coil Cleaning Does for Your System Long-Term

Keeping your coils clean is one of the most cost-effective things you can do for your HVAC system. The benefits go beyond comfort and show up in measurable ways over time.

Your system operates more efficiently, which typically results in lower monthly energy bills.
Clean coils reduce strain on the compressor, which is one of the most expensive components to replace.
Proper heat exchange helps your system maintain consistent temperatures without overworking.
Removing moisture-trapping debris lowers the risk of mold and bacteria growth inside your air handler.
Regular cleaning extends the overall service life of your equipment, protecting the value of your investment.

In a market where summer cooling demands are as high as they are in Dallas, these advantages are not minor. They translate directly into fewer breakdowns, lower repair costs, and a system that lasts longer.

Frequently Asked Questions

How often should AC coils be cleaned?

Most systems benefit from a professional coil cleaning twice a year. Homes with pets, high dust levels, or older equipment may need it more frequently.

Can dirty coils cause my AC to freeze up?

Yes. When airflow and heat transfer are restricted by buildup, refrigerant can drop below freezing and cause ice to form on the coils or refrigerant lines.

Is coil cleaning something I can do myself?

Basic rinsing of the outdoor condenser unit is possible for homeowners, but a thorough cleaning of both coils requires professional equipment and training to avoid damaging the fins or internal components.

How long does a professional coil cleaning take?

In most cases, the process takes between one and two hours depending on the condition of the system and accessibility of the components.

Will coil cleaning lower my energy bill?

It often does. When coils are clean, the system runs more efficiently and does not have to work as hard to maintain your set temperature, which typically reduces energy consumption.
