"I called Hosack on a Thursday morning because my water heater had died, and because of their great Angi reviews. They had a plumber, Kent, at my house before noon. Kent was fantastic ... great work, extremely knowledgeable, and VERY customer oriented. I'm extremely happy with Hosack's responsiveness, quality of work and attention to detail. Going forward, they (and I hope Kent!) are my plumbers of choice. I highly recommend!"

"This company was excellent all the way around. The staff member who contacted me was very nice and helpful. They were able to come out the same day (I did not have heat). They sent me a text message with a picture of the technician which I thought was an excellent feature. The technician, Jeff, was very nice and extremely knowledgeable. I would definitely hire them again because the work was top quality and the cost was fair and reasonable."

"This company was extremely responsive and professional.  Marc was very knowledgeable and worked hard to get warranty coverage for my repair and to get my family back in our home quickly, as we had to leave due to no a/c during a heat wave. I met with him at 11:00 and there was a new unit installed by 4:00 that afternoon.  I would highly recommend this company."

"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!"

"I have used the company many times. Two technicians came out for the tuneup and completed the job in about 2 hours. The company has also replaced the furnace and AC in the past. They are very thorough and professional. The staff is also very friendly and available for service. I am a member of their club which makes them easily accessible to me."

Install Boiler questions, answered by experts

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

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
