"Abel Air came to the rescue! Doug was a godsend for us on one of the coldest days of the winter. He replaced our boiler in a timely manner and did so within the quoted price he first gave us. There was some wrinkles and additional work he did not expect, but he did it all for the same price he initially quoted. Doug and his team are thorough, communicative and completely professional. I would recommend Abel Air for all your HVAC needs. Doug is also one of the nicest guys we have encountered to do work on our home."

"They came out and gave an estimate for a new boiler and we contracted with them for the replacement. The technicians seemed very knowledgeable and thorough. We had a few issues after the installation with air getting in the line and blocking the flow of hot water. However, Our installation came with a 1 year service contract and they returned to remedy the problem promptly and professionally. Bell stands behind their work. We would recommend Bell and will use them in the future."

"David and his crew were great! They were very communicative on what the issue was and responsive to my questions and calls. I had a pipe dug out and replaced in my yard by then. Will definitely hire them again if anything else happens. Would highly recommend to anyone looking for work done correctly."

"As a first time home owner Schede plumbing has been very responsive and professional. Schede plumbing oversaw the oil to gas conversion and installed a new boiler. As stressful as this was and every other plumbing issue in our home, Lou has always answered our calls even after hours to troubleshoot what could be going wrong. If we can't fix the issue over the phone there is someone at our home the next day. His staff, specifically, Kelroy have nothing been short of exceptional. Kelroy always comes to our home with a smile on his face and will not leave till the problem is fixed. Plumbing and heating is the last thing any homeowner wants to deal with but Schede and Kelroy make it an easier pill to swallow."

Install Boiler FAQs, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.
