"Awesome. While I probably could have scrounged around for a slightly better price, the speed, professionalism and quality of the work more than made up for it - and currently being unemployed, I don't say that lightly! They literally came THE NEXT DAY and did the entire install - remove old unit, rework the ducting, install an air cleaner, dress the wiring - all in one day! The job was done with expert quality - no loose wires or hoses lying around, everything square - and they even came back a few days later to make sure the sump pump and humidifier wire working correctly. finally, they called me a week after that, to make sure I got the Peoples Gas rebate paperwork together! I'd recommend them to anyone!"

"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."

"I’ve continued to hired Schavitz for all things A/C and furnace for my home due to their knowledge, honesty, and professionalism. This time met with Craig since he specializes in boiler systems and once again he exceeded my expectations with his knowledge and service. If you want complete transparency and the highest level of service then don’t hesitate to hire Schavitz. Don’t forget to ask about their membership plan.....discounts on annual services, parts, and equipment. Great deal!"

"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."

"Tim came out for an estimate. He was professional and knowledgeable. Not pushy at all. On the day of installation, he and his team were respectful, efficient, and left our home clean. He thoroughly explained everything, and programmed the thermostat for us. We will use them for all future maintenance. Highly recommend."

"Tim came out promptly, made a diagnosis and explained it so that I could understand, and arranged for a replacement the following day. David and David arrived the following day on time and, unfortunately there was 3 feet of snow blocking their path to getting my boiler out and the heavy cast iron boiler in. They worked together to shovel a path, and then worked continuously through the day until the job was done. David did a great job of explaining the workings of the boiler and left the place mess-free."

Install Boiler FAQs, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

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.

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.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
