"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

In most cases, yes, it’s safe to light a gas water heater manually, but you should shut the gas off first, open a window, and let the space air out for about 10 minutes. Modern water heaters shut the gas off entirely if the pilot light goes out, but airing out the area beforehand is good practice and will ensure it’s safe to relight your pilot light manually. Just make sure you turn the gas valve to “pilot” before lighting. If the light keeps going out or won’t light at all, call in a professional.

If you're connecting your gas line to appliances, the pro doing the work may recommend flexible corrugated stainless-steel tubing (CCST). Polyvinyl chloride (PVC) with high-density polyethylene (HDPE) is another relatively inexpensive material commonly used for residential pipes. Ultimately, you'll need to find out what is permitted based on the code requirements in your area.

Only yellow Teflon tape is approved for use on gas lines. Also called yellow PTFE tape, it is thicker and specifically rated for use on natural gas and propane connections. Standard white Teflon tape is not safe for gas applications. If you have questions about sealing gas line connections, contact a pro like a gas line contractor or plumber who installs or runs gas lines.

Sometimes. While many traditional homes use copper, galvanized steel, PVC, acrylonitrile butadiene styrene (ABS), and PEX, mobile homes will typically use PVC, CPVC, or PEX. These materials are more flexible, easier to work with, and handle colder temperatures.

A local natural gas plumber, gas fitter, or gas line specialist should fix gas leaks. Installing gas lines and connections improperly can lead to dangerous gas leaks and explosions. Only a certified plumber or gas line specialist should run gas lines. This is not a job to try out DIY skills, so hire a professional gas plumber or gas line specialist immediately to find the cause of the leak and fix it quickly.
