"In todays fast paced world, it is hard to find people we can trust and to wonder when we purchase something ,whether or not we are going to get a quality product for what we are paying for. I had been looking around to purchase some new windows for several years, but when I always heard quotes on the cost I was unwilling to take the leap. One day, upon hearing a quote of what the windows I wanted replaced would cost me from their sales rep., I took that leap. It was a no brainer. With such a great price, now I wondered if i was going to get quality for what I was paying. I have to tell you I was delighted to see the final results of my beautiful new windows. Not only were all the people I spoke with in this company kind and respectful, but they also helped me set up financing as well. Great Company, Really Good People, Quality Product and Service!"

"Hired Neli for a virtual repair of our Whirlpool washer. Tom was VERY knowledgeable, friendly and professional. We came up with a solid diagnosis of my issue and the replacement parts required. Tom advised me to consider the value of repairing, parts costs and time required, vs. a new purchase and the effort to repair was not going to be simple. We chatted about the pros/cons a lot. As the washer was 6+ years old and there were holiday sales I opted to purchase a new unit. This is the 3rd time I have worked with Neli. All instances have been very productive and positive. "

Install Boiler questions, answered by experts

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

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.

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.
