"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

Install Boiler questions, 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.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

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

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
