"Everything went great from the estimate with Ed to the installation with Wesley and Matt. They were friendly and knowledgeable. It was not an easy installation. I was very pleased with the result. They had respected my property and even called in a roofer to properly vent the system through the roof. They even installed my smart thermostat. I would use them again. Previously, there was electric heat on the second floor. Other companies balked at giving me a solution for gas but they had no problem running the line upstairs. Goodby high electric bills!"

"I hired All Temp to replace my AC and furnace in my condo. Overall, they did a great job. The initial inspection and quote walk through went very well and they answered every question I had. The installation went equally as well. The crew did great work and finished the project in a timely manner. Would definitely recommend them and use them again in the future."

"It went quite well. The technicians (yes, two) showed up close to the scheduled time (there was a window allowed for arrival) and got right to work. They checked the furnace and determined there were no problems and moved on the boiler (we have both forced-air and baseboard heating). There was a problem with the thermocouple and I authorized replacement. All done and gone in roughly an hour. Well done."

"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"WE CALLED TO HAVE THE BOILER FIXED AND HE DID MUCH MORE. HE IS A VERY INTELLIGENT MAN. WHEN I CALLED THEY SAID HE WOULD BE HERE AT 8:30 AM AND HE ARRIVED AT 8:20 AM INSTEAD OF GIVING A TIME RANGE. HE CAME TO FIX THE BOILER AND ENDED UP HAVING THE WHOLE HOUSE TOO."

"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

Install Boiler FAQs, answered by experts

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

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.
