"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!"

"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"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."

"Very well. I felt Craig was very professional and very knowledgeable. I think the previous company did me a favor when I was told they couldn’t service my boiler any longer"

"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."

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

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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