 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. My old heat pump went out in the middle of the summer heat.  Lighhouse came out right away and had me set up with a new heat pump within days.  Ronnie was great.

 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.

Protect Your New Investment

A new system runs its best when it's maintained. The Lighthouse Annual Maintenance Plan keeps your new AC efficient, catches small issues early, and protects your warranty and your investment — season after season.

Still Have Questions? Let Us Help

Should I repair or replace my air conditioner?

If your AC is over 10–15 years old, needs frequent repairs, or a single repair costs close to half the price of a new system, replacement is usually the smarter investment. We give you an honest, no-pressure recommendation so you can make the right call for your home and budget.

How much does a new AC installation cost in Maryland?

The cost depends on your home's size, the system you choose, and its efficiency rating. That's why we offer a free in-home estimate for replacements — so you get a clear, all-in price upfront with no surprises before any work begins.

What size air conditioner do I need for my home?

An AC that's too big or too small wastes energy and wears out faster. Our technicians calculate the right size for your specific home — square footage, insulation, and layout — instead of guessing, so you get even cooling and lower energy bills.

How long does an AC replacement take?

Most standard AC replacements are completed in a single day. We remove your old system, install and fully test the new one, and leave your home clean — with cool, reliable comfort the same day.
