"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

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.  

Yes, you can have a gas line professionally installed to convert your traditional fireplace to natural gas; just know it’ll be an extra cost to budget for. The cost to run a gas line where you don’t already have one is about $540, though most homeowners pay between $260 and $820. Your total could be significantly higher if you don’t already have a main gas line running to your home.

Any gas pipe can leak, especially if it’s old or isn’t properly maintained. However, even with a shovel, plastic pipes are more easily damaged by impact. That’s why it’s so important to have gas lines marked by the utility company before you begin digging for any reason. Some metal pipes, like black pipes, galvanized steel, and copper, aren’t as easily damaged by impact but can degrade over the years, leading to leaks.

No, you cannot plant a tree above a gas line. Tree roots grow and spread over time and can sometimes dent, crack, or penetrate a gas line. Those same roots may also cause accessibility problems for maintenance or repairs. You can generally plant vegetation with non-invasive root systems, low-growing vegetation, and flower beds near gas lines. 

Take this one seriously! If your oven smells like gas when it’s off, this is a telltale sign of a gas leak that can lead to a fire or explosion. In addition, a small leak has the potential to turn into a major leak without warning if any part of your piping or tubing breaks. Potential sources of a leak include the gas valve, burner, joint, or connection lines behind the stove. If the leak appears to be significant, you should contact the gas company or fire department.
