"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 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."

"Posted a job for a boiler replacement on homeadvisor on thursday and got a call in less than half an hour. Ron, one of the owners, said he could come take a look on saturday morning. I got a quote on monday. I decided to hire them on friday. Jeremy the boiler specialist and other co owner came by the the next day to take a few more pictures and check on a few other things. The boiler we decided on was a special order and took a few weeks to arrive. It came in on a monday and was installed by thursday. They started on thursday morning with a two man crew. Around lunch the Jeremy came by to see how things were going. Around 2pm an other two guys showed up to help. At about 3:30 the co owner and boiler specialist came by to oversee the final part of the install and operational testing. I was originally told it would be a two day install. They didn't just replace the boiler, they replaced the expansion tank, dual zone control box, etc. They worked until around 7pm to get it all done in one day. They bled all the radiators in the house and made sure they were heating properly. They took all the old parts with them and left no trash behind. Everybody from this company was extremely professional. They arrived within five minutes of the time they said they would be at my house. Nobody could beat the quote they gave me for the install. Any questions I had were responded to in 30 minutes or less. The install looks amazing so much shiny copper pipe. Cawiamca gave me a 3 year warranty where they will take care of all the labor and parts if anything goes wrong. This was by far the best experience I have ever had with a company coming to my house to do something.They performed consistently above my expectations. They will be the first people I call if I need any more work done on my heating system. I highly recommend Cawiamca."

"Ryan installed a new boiler and indirect hot water tank in my house. The quality of workmanship is excellent. He was prompt and professional at every stage of the project. He explained how the system would work and makes great recommendations that will save you time and money. He answers all questions honestly and thoroughly and will make sure you are comfortable with everything he does. Don't think twice about hiring him - he will be in very high demand as he continues to make a name for himself."

"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."

Install Boiler questions, answered by experts

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.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.
