 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.

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 Humidity in Check Year-Round

A dehumidifier works best when it's maintained alongside your HVAC system. The Lighthouse Annual Maintenance Plan keeps your dehumidifier and system running efficiently, so your home stays fresh and balanced — catching small issues before they grow, season after season.

Still Have Questions? Let Us Help

Why is my house still humid with the AC running?

Your AC removes some moisture as it cools, but in humid Maryland summers it often can't keep up — especially if it's oversized or short-cycling. A whole-home dehumidifier is designed specifically to control moisture, so your home feels fresh and dry even when the AC alone can't manage it.

What's the difference between a whole-home and a portable dehumidifier?

A portable unit only treats one room and needs constant emptying. A whole-home dehumidifier integrates with your HVAC system to control humidity throughout your entire home automatically — quieter, more effective, and far more convenient for lasting comfort.

Can high humidity cause mold in my home?

Yes. Excess indoor humidity is one of the leading causes of mold and mildew, which can damage your home and affect your health. Keeping humidity in a healthy range with a whole-home dehumidifier is one of the most effective ways to prevent mold before it starts.

Will a dehumidifier lower my energy bills?

It can help. When humidity is controlled, your home feels cooler at higher thermostat settings, so your AC doesn't have to work as hard. Many homeowners find they can raise the thermostat a few degrees and stay comfortable — which reduces cooling costs.
