904 During the coldest part of the winter, our boiler system unexpectedly needed urgent repairs to address a diverse number of significant issues. Sostilio & Sons promptly answered my call and had me text a few pictures. John himself, together with his son, then came out promptly to assess the...
Sostilio & Sons Plumbing & HeatingMy old Steam Boiler had a ton of banging, was inefficient and one of the radiators didn't work. I did a ton of research and reached out to many steam heat plumbers. Many of these plumbers charged for estimates, were backed up with work or just didn't want to take the time to explain how they...
Tom stopped by as scheduled and checked the work that I was interested in, namely boiler replacement, leaky radiator valve with corroded pipe and capping off an old gas pipe. He was very helpful and polite. He pointed out that the boiler could last several more years but that the 7yr old...
Quick response to initial call, able to arrange an early morning visit. Took a good look around fireplace, furnace, boiler, dryer vents and flues. Offered good advice but was in no way pushy or attempting to find additional work. Cleaned fireplace flue quickly with minimal disruption and...
Everything went smoothly, from the initial visit to the installation and cleanup. Brian Anderson came out to give us an estimate for a new boiler, and it was clear that he was very knowledgeable about steam heat. He went through every room of our house, measuring the radiators in order to...
Kermit B Schulz & Sons IncThey’ve just been great. They’re responsive. They got 24 hour on call service. When we needed the new boiler, they came right out and do the estimate. They’ve been great. They always get it done in one day.
It was very clean, professional. They did a good job. They were timely. I just thought they were expensive, so I would not use them again. He was recommended by a contractor, who put in our new boiler.
I was very impressed with Fullin Heating. Keith, the owner, was extremely responsive and professional. He explained our options and helped us to select a quality water heater that will have a long life and will easily adapt to the eventual new boiler we plan to get. Fullin was quickly...
Called for emergency service mid morning and tech arrived mid afternoon the same day even though I am not a regular customer. High efficiency boilers require a much higher level of technician and the tech was more than up to the task. Came prepared with spare parts he thought might be...
I started calling various ?Water Heater? people showing up on Angie's List and coincidentally was referred by a colleague to Fernando Gonzalez who was coming up shortly on my list anyways. He, like others understood the situation and explained that this is very likely a new Water Heater...

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
