"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

Gas Leak Repair questions, answered by experts

Element, gas features, and complexity, including venting and connections, are typically higher due to safety and expertise factors.

You may want to remove the gas line if it’s unsightly or if it’s causing a problem with future appliances. The downside is if you decide to go back to gas, you would need to run a new gas line to the area.  The average cost to run a new gas line is $550, but the installation can range anywhere from $120 to $1,350.

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.

You can maneuver your gas grill into place, but you cannot connect the grill to your gas source yourself. All municipalities mandate that a certified plumber carry out this work, so you’ll have to reach out to a plumber or a gas grill installation company in your area. Given how dangerous a gas leak can be, gas lines and connections are highly regulated, so you’ll need a professional’s help and a permit to install a gas grill.

Even though their jobs sound similar—both professions work on pipes—a plumber and pipefitter actually have very different jobs, and pipefitting isn’t considered plumbing. Pipefitting is done in commercial and industrial buildings and factories, and the pipes carry gas, chemicals, acid, and other potentially hazardous substances. Pipefitters often work in intense conditions while plumbers may work in lower-pressure environments.
