"We have central heat, it's like a boiler, and they inspected it and they found that the hot water cut-off part, which is a significant part for operating it safely, was not in good condition. He ordered the part for us, and got it rather quickly, that same week. We like them. They have a provider there, that maintains our type of furnace, which is a Peerless. We like this man, because he knows what our furnace should be like. We've only been dealing with them for, it was last season and the one before. Our previous man had retired and was no longer available. Both times they sent somebody who clearly knows what our furnace should be like, ans when it's operating right."

"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"

Pleased with technician and service, and will do business again them again if needed. Owner called to confirm service and sent a text with name and information about the technician before his arrival."

"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

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.

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.

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.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low.
