"In the end, it worked out okay although I had some trouble in the beginning. The two young gentlemen that came out said I needed repair work and they told me it was a big job that would take 3 days. The price was according but I thought it was expensive. They came back the next afternoon and they were done within an hour. I ended up calling the business to file a complaint and the owner came out. He refunded me part of the money. He settled my issue but I don't know if I would ever use them again because they scammed me when I was originally here. "

"The first guy that came out misdiagnosed the problem.  We had to have them come out again.  He didn't charge us, and did the correct repair.  They were OK with pricing.  Most repair places don't apply the service call charge to the repair charge, but Sears did.  The first person I talked to on the phone didn't know what she was talking about.  That call was very challenging, possibly because of a language barrier.  I would use them again."

Boiler Repair FAQs, answered by experts

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
