"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

Costs depend on the fireplace model, venting complexity, labor, and whether additional structural modifications are needed.

The biggest disadvantage of propane is that heating systems and appliances powered by propane tend to cost more than gas-powered ones. Propane is also dangerous since it can create frostbite if it touches the skin and can easily combust if mishandled. It’s also quite cumbersome to buy or replace propane tanks, so many people choose to have propane delivered to their homes—an extra cost and logistical challenge that can be a headache.

Yes, you can store a propane tank, whether it is full or empty. Remember that the container is contaminated with hazardous materials once it has housed propane, but as long as it’s properly placed in a well-ventilated, temperature-controlled space, a tank is unlikely to cause issues whether it is full of propane or not. 

Only yellow Teflon tape is approved for use on gas lines. Also called yellow PTFE tape, it is thicker and specifically rated for use on natural gas and propane connections. Standard white Teflon tape is not safe for gas applications. If you have questions about sealing gas line connections, contact a pro like a gas line contractor or plumber who installs or runs gas lines.

If you think your home might be experiencing a gas leak, you should immediately leave your home and call a professional natural gas line plumber for assistance. Natural gas is dangerous and highly flammable, so you shouldn’t stay inside your home if you think there might be a gas leak.
