"I found Hosack on Angies list and am so glad I did. They were able to get someone out to me the same day I called. Scott was professional, quick and thorough in his installation of our faucet. It looks and works great. We will definitely return to them in the future for all our plumbing needs!"

"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"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!"

"Called NPM at 6pm because our furnace was leaking water from the bottom and the AC wasn't blowing cold air. Andrew the owner came out because a tech wasn't available, which showed a strong commitment to their customers. He was great at explaining and walking us through every step. Typically highly reviewed or top companies cost more, NPM was really affordable and overall the price was great for a 9pm service call. Highly recommend NPM and will use them again."

Install Boiler questions, answered by experts

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

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.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
