"After talking with several plumbers, I decided to use Southeast Plumbing and Gas. Brian answered all of my questions and quoted me a very competitive price. Brian installed a new dishwasher, put in a new tankless water heater (plus ran new electrical for the unit) and some other smaller fixes. He was professional, courteous, and did the work for what he quoted. He also tackled some additional plumbing issues that cropped up while he was doing everything else. He was at our house for over 12 hrs fixing everything and making sure everything was working properly before he left. I would definitely recommend SE Plumbing and Gas and would use them again."

"The contractor performed an outstanding installation. The first visit, he assessed the work to perform, then walk me through the process he would perform. He offered various units to accommodate my requirement before I decided on the best option. On the day of the installation, he arrived on time, took the necessary safety precautions, did the installation and then walk me through the process of what he performed and showed me the operations. His quality of work (A+) and the cost (A+) met our expectations."

Install Boiler questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
