"We built our house 20 years ago. We discovered the master bathtub was leaking to our family room. Glenn tried to just reseal the drain but found our builder used the wrong materials and didn't properly configure it. Glenn apologized for having to cut the ceiling to get to the pipe that needed to be replaced but finished the repair quickly and cleaned up everything. I would definitely recommend Glenn at Hosack Plumbing to anyone needing plumbing help."

"We found SmartHouse almost by accident while looking for solutions to what turned out to be botched previous AC installation by a much bigger and more established company who we had trusted to do a decent job. Instead we ended up with a system that wouldn't cool the house. Smarthouse first correctly diagnosed the problem, then fixed it, and advised us on how best to heat and cool our 100+ old house. We now have a service contract with them for regular maintenance and they recently installed a mini-split for us. Their techs are great. Just the sort of people we would feel comfortable leaving alone in the house to finish a job if necessary."

"Here’s a polished review that highlights the service, professionalism, scheduling, communication, and Patrick specifically: I had a great experience with this company from start to finish! Scheduling was easy, communication was clear and consistent, and the service was completed quickly and professionally. Patrick, the technician, was especially great. He was knowledgeable, professional, friendly, and did an excellent job fixing and replacing my dryer duct. He explained everything clearly and made sure the job was done correctly. I really appreciated how fast and efficient the entire process was. Excellent customer service and quality work—I would definitely recommend this company to anyone needing any of the services they offer!"

"The 3 Mustache Pledge! Schraer Heating and Cooling deserves every bit of praise I can give! I called them about a worrisome noise coming from my system — one that I could only describe through a few rather vague and comical sound effects. Despite my less-than-technical explanation, their technician quickly understood exactly what I meant, found the issue, and had it fixed in no time. Their professionalism, responsiveness, and ability to solve the problem so efficiently (and with good humor!) made the whole experience stress-free. I’m so grateful for their excellent service and expertise. Highly recommend Schraer Heating and Cooling to anyone looking for honest, skilled, and friendly professionals! I will definitely keep my maintenance agreement in full force and effect!"

Boiler Repair questions, answered by experts

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

If you don't clean a boiler, you may have higher energy bills or no heat. A dirty boiler is inefficient and can't properly maintain a heating system. It may break down more often due to corrosion or clogs from soot and oil buildup. Cleaning a boiler improves its performance. The cost to replace a boiler can be expensive, so keeping it clean is a cost-effective practice.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.

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.
