"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

It's a pleasure to greet him semi-annually, since he's courteous, pleasant, and professional, and since he answers all my questions re: my heating and cooling systems. I trust this talented tech being inside my home and tuning up all these systems. Kudos to Tyler Heating & A/C for hiring Chris as its employee."

"Mike contacted me within minutes of my request. It was the day after the coldest day we've had and we thought we would have to wait for an appointment. I explained that we had no heat Mike told me that he could have someone over within 2-3 hours. He told me what the cost would be which was very reasonable. Joe arrived as scheduled, fixed the problem and cleaned up the area. Within 2 hours our boiler was back up and running. I would highly recommend Mike and MTL and we will be using them to service our boiler for our future needs"

"They were great! Even found a way of adding a 40 gallon water heater to a smaller space. Which has been wonderful! They worked in a VERY tight space and got the job done! I highly recommend them! Will be using them to install my central air as well!"

"Jeremy came the evening of the day I called him accommodating my schedule. It wasn't even an emergency, at least I didn't think it was. I called for a cleaning but he immediately identified a problem I didn't know I had. He walked me through the diagnostic, described and demonstrated the problem, quoted the job and when I accepted it he performed the repair. When he left my boiler was working efficiently. The boiler was working but the heated water wasn't circulating through the baseboard. I was constantly burning oil with minimal effect. It had felt drafty in the house and I was relying largely on a gas fireplace to take the chill out of the air. That's no longer the case, the house is warm. He's coming to clean the boiler Wednesday evening. I will never hire anyone but Jeremy again to maintain my boiler."

"Gary (owner), Brian and Bill did an excellent job replacing our propane gas furnace. Good pricing, speedy service, new furnace installed in 24hours from first visit, quote in February during supply chain issues, no easy feat, and replaced with a quality name brand. Don't hesitate to hire them if your system stops working."

Install Boiler questions, answered by experts

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

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.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
