"We recently had a new combi boiler installed by CRS Heating & Cooling System, and we found that they do excellent work at a fair price. Bob provided quotes for different brands and patiently answered all of our questions so that we could make the best decision for our family in replacing our old machine. Cody is professional, skilled, and took the time to be sure that our new combi boiler was properly installed. We are so fortunate to have found Cody and Bob at CRS Heating & Cooling System, and we plan to call on them for all of our future heating and cooling needs."

"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."

"East Coast Plumbing and Heating provided us with a great service on a big job of replacing our 30 years old furnace. Dylan was very accommodating and explained the process in a great detail. His estimate for the job was honest and fair. Dylan and his crew did the job in one day and did an excellent work for a reasonable price. We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."

"I hired TCC three weeks ago to install a heat pump mini-split systems for my 4 BR home. Their quote was competitive, their install went as planned, and the technicians were super knowledgeable and worked hard to do it right. I am thrilled with the results. I have recommended them to family already and TCC will get more business."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"Devin Coleman was prompt, courteous, professional and well informed. He advised us and responded to our requests. His estimate was easy to review and he answered questions effectively. Triumph's lead technician, Andrew was clearly a professional who knew both the products and the complicated installation process. His installers included Josiah, Austin and Devin and they were all hard working and interacted well together and with me. I appreciate their attitude and the work they performed. We are delighted with our new system which effectively cools, heats and dehumidifies our home. I feel that this is the best purchase we have made in remodeling our home. Thanks to all of you!"

Install Boiler FAQs, answered by experts

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.
