 Trustindex verifies that the original source of the review is Google. The tech who came out to clear drip line from ac unit was great and very efficient. Would use their service again if needed.  3 text messages for this survey in a week seems a little heavy. Doing this to stop the text messages.

 Trustindex verifies that the original source of the review is Google. What a great company this is. I called at 3:00 on a Friday afternoon and they had a tech in my area who was there at 6. He quickly diagnosed the problem and got us up and running again. Very friendly and professional all around. I highly recommend and will definitely use them in the future.

Keep Your Coils Clean Year After Year

Coils get dirty again with everyday use — that's why routine cleaning matters. The Lighthouse Annual Maintenance Plan keeps your coils clean, your system efficient, and catches buildup before it turns into a costly repair, season after season.

Still Have Questions? Let Us Help

How do I know if my AC coils need cleaning?

Common signs include weak or warm airflow, rising energy bills, longer cooling times, or a frozen evaporator coil. If your system runs constantly but never quite cools, dirty coils are often the hidden cause. A quick inspection tells us for sure.

Should I clean or replace my coils?

It depends on their condition. Coils coated in dirt or debris can usually be cleaned to restore performance. But coils that are corroded, bent, or leaking refrigerant need replacement. We inspect them and give you an honest recommendation — never an unnecessary upsell.

How often should AC coils be cleaned in Maryland?

For most Maryland homes, once a year is ideal — typically during a spring maintenance visit before cooling season. Homes near dust, pollen, or heavy tree cover may benefit from more frequent cleaning to keep the system efficient.

Can dirty coils increase my energy bill?

Yes — significantly. When coils are dirty, your system has to run longer and work harder to move heat, which raises energy use and wear. Cleaning them is one of the most cost-effective ways to lower your bills and extend equipment life.
