“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 Airflow Strong Year-Round

Even a well-designed duct system loses efficiency as connections loosen and debris builds up over time. The Lighthouse Annual Maintenance Plan keeps your airflow strong and balanced, catches small leaks before they grow, and helps every room stay comfortable — season after season.

Still HaveQuestions? Let Us Help

Why are some rooms in my home always too hot or too cold?

Uneven temperatures are usually a ductwork problem, not a thermostat one. Undersized, leaky, or poorly designed ducts can't deliver conditioned air evenly, so some rooms get too much and others too little. Redesigning the duct system to match your home's layout is what finally fixes it.

How do I know if I need new ductwork?

Signs include uneven room temperatures, weak airflow, high energy bills, excess dust, and visible or audible leaks. If your system is the right size but comfort is still poor, your ducts are often the culprit. We inspect your ductwork and tell you honestly whether repair, redesign, or replacement makes sense.

Can bad ductwork raise my energy bills?

Yes — significantly. Leaky or poorly designed ducts lose conditioned air before it reaches your rooms, so your system runs longer and works harder. Sealing and properly designing your ductwork can noticeably lower your energy bills while improving comfort.

Do I need to replace all my ductwork or just part of it?

It depends on the condition. Sometimes sealing and modifying key sections solves the problem; other times an aging or badly designed system needs full replacement. We assess your ductwork thoroughly and recommend only what's needed — never more.

Do you offer free estimates on duct design and replacement?

Yes. Free estimates apply to all system replacements. We'll assess your ductwork and airflow, explain your options honestly, and give you a transparent price — with no diagnostic fee and no obligation.
