"I was in the market for a ductless AC system for my house. With a project like this, it is wise to get multiple estimates and do your research. Cawiamca came right away to provide me with an estimate, came in at the best price, and could start the work the soonest. They installed three head units in the bedrooms and one in my living area. They left no mess in my home and placed drop cloths at the entrance. They went the extra mile to make sure I was happy with my AC system and stand behind their products and labor. I would highly recommend them."

"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!"

"Jeremy and his team gave me the best contractor experience I've ever had. He listened to what I wanted, provided a fair quote for a central A/C replacement (air handler and condenser), and never pressured me or tried to upsell. In passing, he mentioned a heat pump option for the shoulder months to reduce oil use, but that was it. After doing my own research, I called him back with questions, and he took the time to walk through the pros and cons honestly. There was no sales pitch, I actually asked for a quote heat pump quote too, because I saw the benefits myself. I ultimately chose the heat pump and appreciate that Jeremy gave me the information needed to make an informed decision. His crew was fantastic, friendly, professional, and thorough. They removed the old system and completed prep work on day one, then finished the install on day two and walked me through everything. Great communication, great pricing, great workmanship. I highly recommend Jeremy and his team!"

Install Boiler questions, answered by experts

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

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.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
