"Angie's list recommended them to me. I called Greg to request an estimate on installing a new boiler. Greg and Ben arrived when they said they would., Very professional gentlemen. After looking over my system and chatting a bit Greg made a couple of boiler recommendations. He sent me the quotes in a couple of days as he stated. I felt they were Very reasonable quotes but due to inflation we're a little more than I was planning on. I agreed on one , Greg ordered the boiler and told me he would call when it came in. About 10-12 days Greg called, said the boiler was in ,they had it assembled at the shop and could they bring it up that afternoon. They arrived when they said, got the boiler in the basement and said they would be back in the a.m. to install. When they arrived I asked if they minded me watching just see if I could p/u some pointers. What a pleasure to watch these 2 men work together. Very professional,,kept a very neat work area and paid exceptional attention to straight, level, and plum piping.When they finished Greg went over operation of the boiler and answered any questions I had. I will use them in the future as needed and HIGHLY recommend them to anyone."

"I posted I needed a window AC unit removed and this company was the only one to respond. The owners wife responded with in an hour, told me they would be at my house 3 days later. I responded, can you give me an estimate of how much it would cost. She responded, sir there is no charge, we just like helping out the community. I was shocked. Being on a fixed income. Craig arrived, removed the AC, and I started asking questions about mini split systems. He was here at least an hour explaining how they worked and my options. I have now ordered my new AC slash heatpump, to be installed. There was no pressure, just me asking questions and I loved what he had to say. Perfect gentleman."

"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"Sunrise Heating and Cooling did an excellent job installing my new Rinnai tankless water heater/boiler. From start to finish, the experience was smooth and professional. The crew was knowledgeable, punctual, and took the time to explain the system and answer all of my questions. The installation was clean, efficient, and clearly done with attention to detail. Everything works perfectly, and I couldn?t be happier with the upgrade. It?s clear they take pride in their work. If you?re looking for reliable, honest, and high-quality service, I highly recommend Sunrise Heating and Cooling."

We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."

Install Boiler questions, answered by experts

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.

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

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Costs depend on issue severity, parts needed, and labor rates.
