"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

Boiler Repair questions, answered by experts

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

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.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.
