When it comes to gas, safety comes first. Lighthouse HVAC diagnoses gas heating systems with precision — pinpointing leaks, combustion issues, and performance problems, and giving you honest answers with no scare tactics, just the truth about your system.
Gas heating problems often show up as warning signs long before they become dangerous — uneven heat, strange smells, a pilot that won't stay lit. Our technicians diagnose the root cause safely and accurately, so you know exactly what's happening and what it takes to fix it.
With a gas system, guesswork isn't an option. Proper diagnostics protect your family's safety, your comfort, and your equipment — and give you the honest answers you need to make the right decision.

“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.”

Catch Gas Issues Before They Become Emergencies
Many gas and combustion problems develop quietly over time. The Lighthouse Annual Maintenance Plan includes thorough safety and combustion checks at every visit, catching issues early — protecting your family and your peace of mind, season after season.
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.
Is a gas furnace leak dangerous?
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.
What causes carbon monoxide in a home heating system?
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.
How much does gas system diagnostics cost?
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.
Will you try to sell me a new system?
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.
