"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

Evacuate immediately and call professionals for emergency inspection and repairs.

Plumbers start by walking around the property to see if they notice any signs or sounds of a gas leak. They can also use tools like electronic gas detectors and infrared cameras to find the source of leaks. There are also detectors that use laser, thermal, and multi-wavelength imaging. All these devices allow a plumber to scan your home and pinpoint the exact location of a leak.

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

No, fixing or patching a hole in a gas line may not seal it completely. A patch should be a temporary solution because the damaged area will be weaker than the rest of the pipe, increasing the likelihood of future leaks. Therefore, if a gas line incurs damage, call a licensed plumber and have it replaced right away.

For one, natural gas is more affordable than electricity, meaning your wallet might see an overall savings over time. The biggest positive of installing a gas line is that gas-powered appliances will still work during a power outage, so your gas fireplace will keep your home warm and toasty during a blackout.
