Between plumbing, AC, and heating service plus emergency response availability, Horizon has a lot to offer the average homeowner.

Air Conditioning

AC is the quintessential summer accessory. Without air conditioning, you are in for a long and uncomfortable summer. But a professional tune-up can keep your AC from quitting. Regular upkeep ensures good performance year after year. And if you need a replacement? Horizon handles those, too.


Did you know that you should have a heater tune-up at least once per year? Most homeowners wait until their system breaks to act. But with Horizon, we take the stress out of heating maintenance by checking in regularly. We perform repairs, replace parts, and overhaul entire systems as necessary.


Plumbing is about more than your faucet and drain pipes. Piping is complicated and susceptible to all kinds of damage. From freezing in the winter to excess pressure in summer, you never know how your pipes will fare. Fortunately, Horizon can inspect and repair every part of your home’s plumbing—even in an emergency.

Horizon Loves Columbia

From picturesque Lake Kittamaqundi to the shoppers’ paradise Columbia Mall, there’s a whole lot Horizon loves about Columbia. And it’s not just the accessibility to nature (thanks to Robinson Nature Center) or the lively social scene.

We appreciate the many customers and families who depend on us in and around Columbia, MD, 21029. Keeping your plumbing plus heating and cooling in order is our passion and our purpose. We’re grateful for your trust in us, and we hope to be part of the landscape of the town well into the future.
