"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Very please with the install. Vin was very professional and applied due diligence to the project. His oversight and instruction provided the reinsurance that needed. I requested four heating and AC vendors to provide proposals. Tyler was most responsive to my questions and offered me alternatives along with helpful suggestions. My next project is my boiler. I will be turning them in the future."

"Prompt, efficient service --- Technically knows gas furnace products --- More importantly knows the economics of keeping up with repairs on a 30 year old unit vs going with a new unit --- Not a sales pitch -- just facts ---- Went new and the cost including nicely done installing was much lower than I originally thought it would be .

"I lost heat in my home on Friday, this is after I had a local handy-man come on Thursday to bleed my pipes because of water flowing sounds in my base-board, which I also had done last year. I called and waited for the same handy-man to come back on Friday after his regular job and was then I was basically told by the handy-man he probably couldn't do anything further to get it running and recommended I contact a professional. It was now close to 5pm on Friday so I went online and found Select Mechanical Services and filled out the Home Advisor quick on-line question which included how urgent it was and instantly after I did, I received a telephone call from Gary at Select Mechanical and he came on Saturday morning, as I had told Gary I was using electric heaters, so I was okay for Friday night. I don't mean to repeat a previous high rating post, but again he was a great service man, knew his stuff, very friendly and kept me informed of the problems and issues at every stage. I will admit that I had not had my furnace professionally service/cleaned for a couple of years, so Gary had found more than one (1) problem and fixed them all! I highly recommend using Select Mechanical and a Professional."

Install Boiler questions, answered by experts

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
