When we bought the 19th century townhouse in Brooklyn plumbing was the main issue. The boiler looked like it would explode at any moment, there was a weird second water heater kind-of hooked in, the sewer cleanout was all wrong, there were multiple fire dangers in the way things were vented...
The service tech was very professional, knew his trade and had my boiler back up and running in very quickly. He answered all of my questions in clear understandable terms and even gave me advice on basic homeowner maintenance and checks. I feel confident that any future boiler problems will...

"We had S&J install a new mini-split ductless system on a floor that we couldn't get cool. We also had them analyze our current system in our townhouse, which required an upgraded cold air return duct due to a bad design by the builders. Mitch was our representative, and he did a fantastic job analyzing what we needed. Mitch provided a better, more effective solution than we had heard from any of the other vendors. Additionally, he got us a great price (after rebates) on a system that was better than the other systems we had been previously quoted. The mini-split installation was a challenge, but the installers did a great job. They took their time to create an installation that looks and operates great! The cold air return duct upgrade brought our system static pressure from 0.75 inH2O down to 0.5 inH2O total, which is nearly perfect. Our air handler is running quieter now, and we are getting more airflow through our system. I would give Sanders & Johnson 10 stars if I could!"

"Had maintenance contract with Absolute to service HVAC, electrical, plumbing twice a year. On recent maintenance visit A/C condensation line was found to be clogged due to "dirt getting into the system from lack of filter maintenance". Cost $329 to clean line which was not covered under contract (and seems a bit excessive!!). Was told filter replacement was not covered in maintenance contract. Seems to me that this would be a priority maintenance item! Technician comment on last visit 5 months earlier stated filter was "still clean" and not replaced. Needless to say we will be finding another company to do our maintenance from now on."

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.
