"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

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.
