"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."

The easiest way to empty a propane tank is to simply use it until no propane remains. If you’re short on time and need a faster solution, transfer the propane to another tank instead. Wear leather gloves to protect your hands, then connect the hoses from both propane tanks and seal them tightly. Turn the knob to open the supply tank valve on the full tank and let it run until the pressure pushes all the propane into the other tank. When all propane is transferred, remove the hose and seal each tank. 

This is a matter of personal preference, as each method has its own pros and cons. Oil furnaces are safer, but the smell can be off-putting to some consumers. Oil is also more expensive than gas. However, oil furnaces boast a higher BTU rate per hour, so a smaller amount of oil can heat a larger space when compared to a gas furnace.
