"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Gas Leak Repair questions, answered by experts

Costs depend on furnace size, ductwork modifications, labor, and efficiency ratings of the chosen system.

Yes, it’s possible to convert an oil furnace to gas. However, you may have to replace the furnace completely instead of simply converting it. If the original oil furnace has had any type of damage or is older (typically considered over 15 years old), then you will likely need a full replacement versus a conversion.

Temporarily capping a gas line—for renovations or during travel—doesn’t require a permit. If you plan to remove a gas line and cap it completely, you’ll need to apply and pay for one through your town or city. Depending on your region and its local codes, you may pay between $25 and $100. To avoid a gas leak or other hazards, some cities take the job of permanently adjusting or capping a gas line out of the hands of homeowners. Instead, they require hiring a professional gas plumber.  

Pipefitting is a more specialized profession, and pipefitters work with complex systems and low- and high-pressure pipes, so it can be considered harder than plumbing. Though each profession comes with its challenges, the nature of pipefitting requires working with heavier materials in fast-paced and dangerous environments, which can be more challenging than working on residential and commercial plumbing systems.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.
