"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."

"Jarod installed a new high efficiency boiler and extensively re-plumbed our central heating system about 12 years ago. He is quite knowledgeable and explained clearly the work he would be doing. The project was completed in a timely manner to our complete satisfaction. I highly recommend him."

"I called to make on appointment for an estimate to replace our 30 year old boiler. The appointment was on my day off a few days later. Mike showed up on time. He inspected the boiler and the house, asked questions about the house and what I wanted. Gave me advice on what I wanted to do. Mike e-mailed me three quotes a few day later, with specs on the boilers. Called me a few days after that to see if I had questions. I made the appointment for the install, again, on my schedule. Mike and his crew showed up on time. We went over what was expected, and his crew was off the the races. They removed the old boiler and installed the new boiler as promised. Mike and his crew were very professional at all times. Highly recommend Ethical Home pro."

"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."

"They came when scheduled, did very careful job, attentive to details. The office scheduled the required plumbing and electrical inspections by my town (for new boiler) and that was efficiently handled too. The salesman who made the initial presentation was very informative and measured home carefully before making his recommondation. Very pleased with Heritage."

"He replaced a very old boiler and hot water heater. Now I have an efficient combi system that works very well. Justin communicated the steps involved and his schedule every step of the way. He was professional and cleaned up each day before he left. He also put a mini split in for me so I have air-conditioning now."

Install Boiler FAQs, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

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

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
