"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"We met with Jeff initially for an estimate on a property we were purchasing. He worked with us to have the work performed right after closing. His crew did a great job, all work was performed as outlined in the estimate with no hidden charges. We did add a couple small items to the scope of the project with no problems. His crew removed mold damaged materials and sprayed to deter future mold growth. They also installed a new sump pump and a perimeter system at the back of our basement, as well as a new bath vent in the attic. Work was performed timely and to our satisfaction the first time. Gabe was the project manger on site and was very good at responding to our questions throughout the project. We would recommend Charter Oak for both mold remediation and basement water proofing. They use the same perimeter system as another highly rated company on Angie's list."

Boiler Repair FAQs, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Even if you do everything right, your boiler’s pilot light might not come on. This has a number of possible causes, but the most common is a blocked jet. These jets are small and clog up even with a small amount of debris. You can clean it yourself or hire a pro to replace the component. Other possible causes include a faulty fan and frozen pipes, among others.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.
