"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!"

"Father son team installed a high efficiency gas boiler and water heater. They did an excellent job replacing the old boiler and were fairly priced compared to the other estimates I received. The new system is working well and looks great. I would use them again."

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours.

"Our Burnham boiler has been giving us issues this winter after just purchasing the new house over the summer. We've come home a number of times to no heat and a cold house, but had luckily managed to YouTube our way into figuring out fixes. This time unfortunately we couldn't figure it out and needed to search for an HVAC contractor. Green Energy was the first company I could even get to answer my call. At 9am Melissa was able to set me up with a day of appointment, Terry was at our house by 1pm. Since this boiler type is still new to us, Terry was great with explaining the workings of the equipment, and just some general tips for upkeep. It ended up being a simple fix with a loose relay, however I would of never been able to figure that out on my own. Terry ended up also doing a general servicing and cleaning of the unit, which they recommend annually to help the equipment last longer (we're positive the previous owners never did it). I would highly recommend Terry, he was knowledgeable and overall good guy. We also plan to sign up for their annual membership program and use Green Energy moving forward."

Install Boiler questions, answered by experts

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

Costs range from $3,000 to $7,500, depending on system size and efficiency.
