"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."

"Went great. Maddie H. came by and found the problem with my old water heater. She setup the install for me. Bradley K. installed the new water heater the next day and did an excellent job. Both individuals were very knowledgeable and a pleasure to work with. Great job to everyone concerned. Thanks!"

"Electrician was prompt and friendly. Worked very quickly. I had purchased a full day and he had gotten through most of my items by the mid-day point. A couple of my ceiling fan light kits were not working properly and needed a little extra attention to troubleshoot. Also the doorbell I had purchased needed a transformer in order to complete install. The tech was eager to leave and said he would come back another day if wanted him to. When I tried to schedule a follow up, he was booked up for at least the next 3 weeks. I was disappointed that since I had paid and booked for a full day, he didn't stick around long enough for me to run to the store and get whatever supplies might be needed so the job could be finished that day. Also after he left, we realized one of the regular light fixtures that was installed wasn't working. Considering I paid for a full day and only got a half day of work, and had to pay someone else to come back and finish the job, I don't feel like I got a great deal."

"A large tree fell on my home during storm & I hired another contractor to complete repairs which included replacing 9-12 rafters/sheathing/shingles, re-building small front porch & adding 3 windows to sunroom. Original contractor installed the windows & did a lot of work on the roof but were very slow & work was sub-par.....they also had issues getting project permitted & I finally had to let them go. I was in a real bind to get repairs completed as I was in the middle of re-financing house when the storm hit. I contacted Commonwealth & they were able to come out & assess what needed to be done. They got the permits right away & got started. Most of the previous work had to be re-done....they removed the windows & added headers & proper support & re-installed, repaired roof & re-built front porch. All work was done professionally & in a timely manner. Also installed interior trim (baseboards/windowsills/frame) in sunroom, which I requested at the last minute, so house would be ready for appraisal. They did a nice job matching the original trim on older home. Would definitely hire again."

Install Boiler FAQs, answered by experts

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.
