"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."

"I feel Commonwealth Contracting is very easy to work with. Mike Eippert always responds to any questions we may have had during the process of the work. This is the second major renovation we have had done with "Commonwealth" and both times we were very happy with the results. I will say you need to be patient with how long the project may take. We realized all of these contractors are extremely very busy at this time. However, quality was much more important to me than speed, and all of the work we had done is outstanding. As far as price they are not the cheapest nor the most expensive, however, I feel comfortable that what we paid for the complete renovation was very fair. To me "Quality" of work done is most important and that is what "Commonwealth" provides."

Install Boiler FAQs, answered by experts

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

Most installations take 2-5 days, including old system removal and setup.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.
