"Purchased the deal in the evening on Friday Feb 12, 2016. At time of purchase I advised vendor that best way to reach me is by email or Angie's messaging. Also provided two possible dates in March for the work. Winston responded the next day via Angie's message, and we set up the service date for my  next weekday off, March 2. And I sent him some pictures of the plumbing and street valve. Could not get a commitment on an arrival time, but he called me that morning and advised he had a 9am dentist appointment, and would arrive after that. Showed up with his helper about 1.5 hours later. We could not get the street valve cover off, and thought it belonged to the city, so I made arrangements for Winston to come back today, March 15.
I called the city water dept, and they sent someone over, he said it was not their valve, it was mine and he couldn't touch it, I guess each city is different?.
Anyway, I got the cover off with the help of a saw, a big hammer and a pipe wrench in time for Winston to come back today. We communicated via Angie's messaging in the meantime. Still could not get commitment to arrival time, although I asked for 8am.
Called Winston at 8:15 this morning and he said he would be her by 9:15, arrived at  9:00. We could not get the street valve closed, it was stuck. Not surprised, as it has not been accessed in at least 30 years!. We decided he would put the new valve just downstream of my existing shutoff, and from now on, will not use the old one to prevent further leaks thru the valve stem packing. I also asked him to rebuild the hose bib in the garage adjacent to the main valve, and install heat tape on the pipe before wrapping it (I already had the heat tape, just never got around to installing it. When attempting to replace the washer in the hose bib, the retaining screw broke, so he installed a new hose bib into the old valve body for me. Although I was willing, Winston did not charge extra for the extra trip and the extras I asked him to do.
Overall, I am more than satisfied with this experience. My only complaint is not getting an advance commitment on arrival times. But once I did get a time, he was punctual, even early. Would give an A- on responsiveness if I could. But overall, an A experience!
Will definitely use A REAL PLUMBER again. In fact, we already discussed installing a freeze-proof valve for my backyard hose bib.

"I had a lot of additional cost. It ended up at $1500. They only cleaned three, for the big deal. And then, I had a thing that they put in to make sure that the air stays clean. They said I had a humidifier on my furnace and they said that it had to come off. And then, they said you can get a much better one and then they kind of disappeared and they didn't talk about it or really sit down and have a conversation with me. I'm not even sure why they had to take it off or what they did."

Install Boiler FAQs, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.
