"My well pump went out Monday evening, around 6:00 p.m. Hoosier Drain Guys were out of Losantville, relatively close to me in Middletown, and that's who I went with. Got a response within 20 minutes of posting my problem. A technician was scheduled to be here by 8:30 a.m. on Tuesday, was here approx. 8:20 a.m., assesed the problem, gave me the breakdown (best case/worse case scenerio, which is how I like to approach things). Work began on schedule; had a few "bumps in the road" - but the problem was taken care of. I can't say enough good things about the customer service, expertise, and the peace of mind to know a bad situation was going to be addressed and solved. Fantastic company to work with; I highly recommend!"

"I bought a water heater. They first connected me with a plumbing company that tried to add on $270 for additional materials and labor costs that they could not justify. I returned the water heater, and they again connected me to Holthaus. Holthaus called later that same afternoon and scheduled for the next morning. Dan came out and installed the water heater and new stand in just an hour. He only charged $30 for additional materials related to new gas fittings. He was very polite, transparent, and thorough. I would highly recommend them."

Install Boiler questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

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

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
