"Our only toilet in the house was clogged. But not in the toilet it was way down in the line somewhere. I called several plumbers and no one could get to it till after the weekend. It was after hours and I called George's drain left a message and he called me right back. After explaining to him that was the only toilet we had he legitimately seemed like he cared and said that he would be on his way. He showed up about 20 minutes later. Very polite very courteous great attitude. It was quite the job he wasn't able to reach the clog with the normal stuff so it had to bring in the big guns. He had to take out our whole toilet and it's not a normal toilet but he did it I told him just break it and he didn't want to do that. He was here till about 9:30 at night.

Install Boiler questions, 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.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Generally speaking, an oil furnace is safer than a gas furnace for a number of reasons. Both types create carbon monoxide, with the potential for deadly leaks, but it's easier to detect an issue with an oil furnace because you smell the problem almost immediately. Also, oil furnaces don’t connect to a pipeline, reducing the chances of a leak in the first place. Finally, heating oil is not combustible, and natural gas is, so there’s no chance of an explosion and a reduced chance of a fire with an oil furnace.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.
