"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."

"The installers seemed to be quite knowledgeable and professional. They concentrated on doing the lob, were thorough and pleasant. They answered all questions to my satisfaction. Everything was done on time and all equipment and workers arrived on schedule. They were careful not to create any excess dust during the installation and did a good job of cleaning up when the work was done. In spite of the attic temperature being well over 80 degrees, they worked continuously and finished on schedule. I would recommend Airco Home Comfort Services to anyone who is looking for a high quality, professional job. They demonstrated the technical knowledge and engineering capabilities to evaluate the job and to select the right equipment for my requirements, more so than several other providers were able to do. I was not looking for the least expensive job, but for the best engineering capabilities for a fairly large house with a good sized, north facing sun room and many windows.

"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."

"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"

"There was contact from them prior to the appointment and the guys called within 30 minutes when they were to arrive. They replaced our boiler in one day and the second day was to install a Modean heater in basement. The guys were great, very knowledgeable, cleaned up the space very well, and took away the old boiler. The only hiccup was they received an incorrect part for the outdoor sensor; they needed to come back to install it. I was disappointed only when I had to call 10 days later to see when they could come back and put it in. The part must have arrived, because they scheduled us right away (to be installed in a few days). No clue as to why we weren't called when the part arrived to finish the job, but I would still recommend them."

Install Boiler questions, answered by experts

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

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're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.
