"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

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

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.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

You should have a licensed plumber to install a gas line for your new gas fireplace. As experts in all things natural gas, these professionals understand how to work with gas safely to avoid explosions, leaks, and other potentially hazardous situations. They also know how to handle the other aspects of the process, including pulling permits, digging trenches, and connecting new gas lines to old lines.

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.
