"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"Tim came out promptly, made a diagnosis and explained it so that I could understand, and arranged for a replacement the following day. David and David arrived the following day on time and, unfortunately there was 3 feet of snow blocking their path to getting my boiler out and the heavy cast iron boiler in. They worked together to shovel a path, and then worked continuously through the day until the job was done. David did a great job of explaining the workings of the boiler and left the place mess-free."

"The boiler had needed some replacement pipes as well as the solution to the slight smell of gas when near the boiler itself. Prior to calling for service for these issues, I had removed the majority of the damaged piping and purchased all new of what I was able to remove. I couldn't remove the bushing that attaches directly to the boiler or the nipple that attached to that bushing to save my life. On the night prior to the day of my appointment, there was a snow storm and time moved ahead. I had forgotten to move my clocks ahead that resulted in my arriving about 20 minutes late. The repairman was kind enough to not only wait for my arrival, but to shovel part of the snow from my walkway that leads to the basement. This guy is just great. He removed the fused together bushing and nipple in no time flat. It was amazing for me to watch. I had to pick up a couple more pieces of pipe for my job to be completed and we scheduled to continue after I did so. Luckily, The pipe I needed was in stock and he was able to return the very next day, he removed my bushing and nipple, installed ALL of my pipes, and provided and replaced my leaking gas line. MY BUILDING NOW HAS HEAT AND I COULDN'T BE HAPPIER!!! Now I have to have the other parts of the building repaired that were damaged from when the boiler had stopped working and a pipe had burst. You won't be disappointed if you hire Discovery Heating and Cooling. If I have another related job in the future, I will definitely call Discovery. Thanks again Discovery."

"Jose was outstanding. He was very thorough in his approach and talked through all the options and considerations with us in advance of installing two of our TVs on wall mounts. He first came to do an assessment to get a better sense of what the job would entail and then quoted us a fair price. The job ended up taking longer than the initially quoted time, but he held true to the quoted price. He sent us pictures at various stages to ensure we were happy with the result. Would highly recommend Jose for TV mounting and other jobs."

"We just had Corey install our new Ecobee4 thermostat. He is quite possibly the nicest and most professional technician we have ever had in our home. He was meticulous and courteous. We will definitely call this company again, if we ever have any heating or cooling issues. 5 stars!!!"

Install Boiler FAQs, answered by experts

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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. 

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
