"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 did an outstanding professional job installing our new system. He noticed that the LP gas supply pipes were undersized for the systems in our home and upgraded this as well. Joe and his team showed up on-time and quickly had us up-and-running again!"

"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."

"UIC was quick to respond and come up with the quote. Quote was very competitive against others. They were not so eager to do service on my old water heater though (I asked them to replace anode rods). I decided to go with them since their availability was good (2wks) and ratings on AngiesList were excellent while price was competitive. The job went well, though not without hiccups. I was expecting new boiler to be placed on the wall next to the foundation; though they built a new wall in the middle of the mechanical room, which costed me space; they said it will be 3K more to put in on the wall AFTER they arrived on the job with all the equipment and team. They refused to drain old water from my radiant heat system, saying I need a plumber to come for $290 per hour for 4 hours to drain the system and look for preexisting leaks. Had to hire some other plumber who took care of the problem for $215 in a mere hour. After the project was complete, system started to experience leaks. It was due to new drain connector that they decided to use for this project, and I was apparently first customer for it. After 3 unsuccessful attempts to fix the leak, they had to replace the connector, which addressed the issue. In addition, the system was eligible for rebate; however the rebate amount promised ended up being $450 less than actually paid; they quoted natural gas rebate though my system was on propane, which I told them upfront."

"The Daigle plumbing tech arrived on time, worked hard to diagnose the problem. There were a number of unusual issues that he worked through to make the repairs and he returned my boiler to good working order. The first HVAC companyI hired made repeated trips and was not able to correct the problem. Would definitely recommend Daigle Plumbing to others."

"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

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

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.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
