"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"

"The experience was great. I was referred by a friend. I called and set an appointment. The technician was prompt, and very professional. He checked the furnace and described the problem. A major component had failed. He said I had a choice of either repairing the furnace, or replacement. The repair was not something I was interested in, so I chose to replace it. The replacement was done in a timely, and professional manner. I highly recommend All Temp for their professionalism, and making my furnace replacement a very positive experience."

"They've put in a new furnace, water heater, AC, etc. They are very reliable, but not inexpensive. Everything they do is quality and they only work with quality people. I had a problem with the air compressor on our AC right after the warranty had expired. Cahill said that they work with that company all the time and that part shouldn't have gone out that quick. They said they would talk to the company and see that it is made right, and they did."

"Carlos called me the next morning, and sent 2 technicians over. At several points during their stay, they were video call with Carlos discussing the situation. They found a solution and explained to me carefully what they were doing, what the next step is if this step would prove inefficient. Their price was reasonable. Carlos called me several days later to check on the system, and gave me additional advice. I would hire them again."

"My experience working with CR Mechanical Services couldn't have been better. While looking to replace my furnace and air conditioner, I requested quotes from 4 different companies and CR Mechanical Services stood head and shoulders above the others. They provided a thorough HVAC consultation, listened to and answered my questions, and proposed a great new system at an unbeatable price. Rick and Craig just finished the installation today - right on time and right on schedule - and were friendly and professional through it all. My thanks to them, and my highest recommendation to all who are looking for an HVAC company."

"Bought Amana (Single Stage) HVAC System. Our old American Standard HVAC broke. They came in 2 weeks before and replaced the Gas Valve for $600 and 2 weeks later that broke too because of the electric board. They convinced us that instead of spending more money on parts that may also break later it's better to buy a new HVAC system. They recommended Amana dual stage - Variable system but next day they called that it was a mistake to recommend that because it doesn't exist in 15" size, so now they recommended Single stage and lower the price by $500. Not only that, but they helped us and went out of way to accommodate us with price. Likewise, they fixed it during Thanksgiving weekend."

FAQs for furnace / forced air heating system install or replace projects in Lake Forest, IL

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
