"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."

To ensure a steady propane supply, schedule regular deliveries with your provider, monitor usage, and consider keeping a backup supply for emergencies.

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.
