"The installation of a completely new AC system went great! We were informed they were coming with plenty of notice. The two young men, Dustin and Ronnie, couldn’t have been any more respectful, professional, neat, helpful and pleasant. I would highly recommend them and their company, Cawaimca, to anyone! Also, their lead guy, Jeremy, another wonderful young man who was very responsive to our needs and always kept me informed. Five stars for these guys and company!!!"

"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!"

"E-mailed for a quote inquiry for boiler install. Received a call and a visit same day. Ron fit us in for a combi boiler install within a week as we lost hot water. Roy and Austin were true professionals. Very knowledgeable, thorough and neat. A solid company that genuinely cares for its customers. Ron and crew... thank you for everything. You're all top notch guys. We're looking forward to our new mini split ."

"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!"

"Excellent from start to finish. Called early morning and left message with service. They called back shortly after opening and confirmed appointment. They showed up at the expected time and quickly and professionally fixed the leaking pipe. In addition they made time to look at waste line and aging boiler to provide estimates."

"I could not be more pleased with this company or this service. I found them here on AL and with a rebate, it was a great deal. When I called, the woman who answered was extremely polite and helpful and took the time to go over the entire audit process with me (she wasn't rushed as some receptionists are). They sent an email to confirm the date and time.
When the team arrived, they were on time and each of them introduced themselves by name to me before coming into my house. They were all very polite and courteous. The leader (I can't remember his name) gave me an overview of the process and explained things as they went. Basically, they simulate high winds around the house and then monitor for where leaks are. My house is relatively new and has no basement, so it was already pretty efficient, but there were some major leaks by the front door and attic door, which they sealed on the spot. They also showed me that I could hold my hand over any electrical socket, even ones on interior walls, and feel the "wind"--which means air was leaking out those! So I plugged them all with those little socket protectors. The guys also took me into the attic and showed me some leaks, and fixed them--and fixed the attic door by adding a little latch to help it stay closed. All in all, they reduced the amount of air getting into my house by 500 (I forget the units). It was clear they didn't just make up this number--they showed me the number after the first test and then after the second test (when they had treated the problem areas).
I also got a few free CFLs and LEDs, and bought 3 more LEDs since they were at a great price. They left some rebates with me, although all my appliances are new so I didn't need anything. 
When they left, they each said goodbye and were very professional until the end. They were respectful in my home and asked before opening any closets or doors, etc. I felt very safe with them here, which is not always the case when people are in your home working. I think the price is a fantastic one, especially with the AL rebate that was on when I scheduled. I feel I got my money's worth. My husband and I had tried to plug some leaks ourselves, but we didn't really know what we were doing and we had no way to measure if we were really helping anything. This audit gave me hard numbers to look at and I was impressed that they did the fixes on-site (included in the price--for instance, they plugged a whole around my front door frame by installing a clear plastic barrier). It was a great deal and a great experience. Highly recommend!
Bonus--when we resell this house in a few years, I will definitely list that we got a professional energy audit performed on it and that it's very efficient. Definitely a selling point!

Install Boiler FAQs, answered by experts

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Most installations take 2-5 days, including old system removal and setup.

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.

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.
