"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."

"No repair was needed. Bill and Bill came in to review my furnace in regards to an air intake issue. Bill ran a diagnostic and found that one resolution would be to open an existing vent. He also gave me other options. We were told by another company that we would need to make a $1000 vent in our wall in order to supply our furnace with more air intake. This didn't seem right considering we have always had ample air. Bill noticed a vent that was closed and believes this should just be opened."

"Pre-job communication went smoothly, and we were able to schedule an appointment within two weeks. Furnace cleaning, which I didn’t need, was part of the package, but they agreed to substitute the dryer vent cleaning for no additional fee. They followed up few days ahead to confirm. Due to a local shortage of manpower on the work day they had to send a team from farther away. They contacted me at the appointment time and said arrival would be about two hours late. The team arrived in about 90 minutes. The three technicians were friendly and professional, and led by Florien who walked through the house with me to preview the work. Once underway, the men worked quickly to efficiently clean 14 vents and one trunk and the dryer vent, and the job was completed well within two hours. I was impressed by how they all maintained their friendly good humor despite having to work in enclosed spaces on a very hot and humid day. The job was completed at the quoted price, and Florien did not attempt to up-sell any additional services. In fact, they included application of a rodent repellent at my request for no additional charge. Also, I have heard that some service providers may play upon a customer’s fear of fire hazard to sell them a replacement dryer vent hose at a markup. Only when I asked about it did Florien quote me a reasonable $20 for one if it looked like I needed it. Upon cleaning he determined it wasn’t necessary. All around a good experience and we’re glad to have it done. Would hire them again."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Boiler Repair FAQs, answered by experts

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

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.

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

Attempting DIY fixes can be dangerous. Regular boiler maintenance can help prevent overheating, so schedule professional servicing as a preventive measure. In an emergency, telling occupants to leave the house is a good idea. Then, you can turn off the boiler and the gas or fuel supply. Let it cool naturally, and check the thermostat's settings. Ensure there are no obstructions around the boiler for proper ventilation. Monitor the pressure gauge; if it's too high, bleed the radiators if necessary. During this time, bringing in professionals for troubleshooting is also smart.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.
