 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. Amazing work!!! Not only did the fit me in very quickly with same day service, but tech was able to fix my boiler instead of saying immediately (like other companies had) that I needed a new boiler saving me thousands!!

 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.

Make Mini-Split Care Effortless

Mini-splits need regular cleaning to stay efficient and fresh — but it's easy to forget. The Lighthouse Annual Maintenance Plan keeps every zone clean and running its best automatically, catching buildup before it becomes a repair, season after season.

Still Have Questions? Let Us Help

How often should a mini-split be cleaned?

For most Maryland homes, a professional cleaning and maintenance visit once a year keeps your system efficient and fresh — though filters should be checked more often. Homes with pets, allergies, or heavy use may benefit from more frequent care. Regular maintenance prevents most common mini-split problems.

Why does my mini-split smell bad?

A musty or foul smell usually means mold or mildew has built up on the coil or inside the indoor unit — common in humid Maryland summers. A thorough professional cleaning of the unit, coil, and drain line clears the source and restores fresh, healthy air.

Can't I just clean the filters myself?

Rinsing the filters is great routine upkeep and we encourage it. But a full maintenance visit also cleans the coil and drain line, checks refrigerant and airflow, and catches issues you can't see — the parts that actually prevent leaks, odors, and breakdowns.

Does cleaning really improve efficiency?

Yes, significantly. Dirty filters and coils force your mini-split to work harder for less comfort, raising energy bills and wear. Cleaning restores proper airflow and heat transfer, which lowers your bills and helps every zone cool and heat the way it should.
