"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

Yes, it can be worth installing a gas fireplace, depending on your home heating needs. The cost to install a gas fireplace can be much lower than the cost to install a comparable wood-burning fireplace. The convenience of starting a fire with the flip of a switch and turning it off just as quickly makes a gas fireplace a big time saver over starting and maintaining a wood-fueled fire. A gas fireplace also does not require ash cleanup or frequent chimney cleaning to remove creosote and other buildup that can lead to chimney fires. Gas fireplaces burn and heat much more cleanly than wood fireplaces.

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.

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.

There isn’t a way to convert electric fireplaces easily or cheaply to gas. The process requires major renovations, as opposed to wood fireplaces, which are often already vented and have space for the gas-burning equipment. To convert an electric fireplace to gas, you’d need to remove your old fireplace and get a completely new install.

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.
