"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

You will need to hire a professional installation technician or plumber to connect your dryer to your gas line or install a new line. Your gas company may be able to help you find a capable, reputable professional in your area.

Appliances typically connected to a gas line include gas stoves, water heaters, furnaces, and gas fireplaces. Essentially, any appliance in your home that uses gas needs to be connected to a gas line, which connects your home with the main gas line owned and operated by your gas company.

Shut-off valves, like any other piece of metal hardware, can corrode, age, get worn down, and eventually break or rust into place. Occasionally spray your shut-off valve with WD-40 to stall it from rusting. If it really gets stuck, a wrench and WD-40 will usually do the trick, but you will need to call a plumber if it’s completely unmovable.

Installation typically takes 1-2 days, and repairs can often be completed on the same day, depending on their complexity.

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