"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

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

  • Cap a gas line: $75–$150

  • Gas system inspection: $150

  • Pressure test: $75–$500

  • Damaged or corroded pipe: $6–$7 per linear foot

  • Repair gas leak: $120–$5,000

It’s no secret that natural gas differs from propane, but you’re in luck—licensed plumbers can also install propane gas lines. When you speak to a gas plumber near you, be sure you specify that your project will be for propane gas, not natural gas. Propane lines are slightly different than natural gas lines, so clear communication is key to ensure that your project is completed without a hitch. 

Installing a gas line can be extremely time-consuming and dangerous, so you will want to hire a seasoned professional. Perform a thorough search ahead of time to find a reputable and reliable plumber. Pay special attention to licensing and insurance as you go about choosing the best contractor for your needs.

Take this one seriously! If your oven smells like gas when it’s off, this is a telltale sign of a gas leak that can lead to a fire or explosion. In addition, a small leak has the potential to turn into a major leak without warning if any part of your piping or tubing breaks. Potential sources of a leak include the gas valve, burner, joint, or connection lines behind the stove. If the leak appears to be significant, you should contact the gas company or fire department.  

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.
