"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"Brian at Clear All was recommended by a friend and they lived up to the recommendation and beyond. Helped trouble shoot a broken boiler for my in-laws and once he saw it he highly recommended replacing the boiler. I knew this was not an up-sell as the boiler was in very rough shape. While the new boiler was obviously more expensive then the repair, the price quoted for the boiler, burner, install, and removal of the old system was very fair - too good to pass up and risk throwing good money at bad with a repair on a 20+ year old boiler. Contacted them on a Monday, Brian showed up on that Wednesday to assess the situation and the new boiler was installed and running by 5 pm Thursday. He kept me in the loop through the whole process even though it was my in-laws boiler install. He also took the time to evaluate the size of the house and recommended a much smaller boiler - the existing one was way oversized and therefore over-using heating oil."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Project: Replace Boiler and Hot Water Heater It is refreshing to find a contractor during theses times that takes the time to explain all the options you have available and answerer all of the questions you have. Most contractors just give you a price and that is it. Jarod really does go above and beyond and gives you that personal touch and honesty. We did receive other quotes and went with Jarod not because of price, but because of the service he provided during the quote process and the time he took to answer all of my questions. We choose to go with Natural Gas Boiler and a Tankless hot water heater. He showed up on time and kept us informed throughout the process of what he was doing. Did a great job on installation very clean. Will defiantly be using Jarod Moulton Mechanical Services for future service needs. Great Service means a lot and Jarod provides that."

"Kyle P. did all the water related services. Last year he installed a water softener tank and this year installed a sediment filter and UV tank as well as an arsenic treatment tank. He is always on time, explains work thoroughly, he's neat about his appearance and how he handles the work environment. Kyle is personable and pleasant.Highest recommendation. This company installed the ductless midi's in our home 3 years ago and in every aspect they are fantastic."

"I called NRG Management and talked to Andrew around 9:30 AM, he was in my town by 11:00 AM. My heating system had seen the end of a 30 year run, and my family was without hot water. Andrew gave me a price for the job completed that beat any of the other companies quotes, I checked reviews and I felt comfortable to do business with Andrew and NRG. Andrew said he would be over by 7:00 PM to do the install, after he finished his workday. Andrew showed up with a new Buderus boiler, a Riello burner and 4 circulator pumps, a zone board and tiger loop with flex lines, all new plumbing with copper lines. This guy is Superman, after a full day's work he came to my home and did the install so my family would have heat and hot water, he finished at 4:30 AM, WOW. Andrew replaced my whole system the same day I called, he did a clean first rate job, and beat every other quote, my boiler room looks clean and professional. I highly recommend NRG Management and Andrew, the level of expertise on the equipment recommended and the install was second to none. I got my moneys worth, plus some = 1 HAPPY CUSTOMER. 5 Stars Thanks Andrew, The Harvey's"

"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."

Install Boiler questions, answered by experts

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.
