Still HaveQuestions? Let Us Help

How do I know if I have a gas problem with my furnace?

Warning signs include the smell of gas near the furnace, a yellow or flickering burner flame (it should be blue), a furnace that won't stay lit, soot buildup, or strange smells when the heat runs. If you notice any of these — especially a gas smell — turn off the system and call for a professional diagnostic right away.

A gas leak or combustion problem can be serious, which is why accurate diagnostics matter. Faulty combustion can also produce carbon monoxide, a colorless, odorless gas. We test thoroughly and honestly so you know exactly what's happening — without unnecessary fear or pressure.

Carbon monoxide can result from a cracked heat exchanger, incomplete combustion, or poor ventilation. Our diagnostics check for these specific issues. We recommend every home with gas heating also have working carbon monoxide detectors as an extra layer of protection.

A diagnostic visit carries a clear, upfront fee, and we explain exactly what's included before we begin. Once we identify the issue, you'll get transparent pricing for any repair — so you can decide with full information and no surprise charges.

No. Our job is to diagnose the real problem and tell you the truth — even when the honest answer is a simple repair. We built Lighthouse on trust, not sales tactics, so you'll always get a straight answer about what your system actually needs.
