"The only time they had available was in the evening so I had to pay double the amount or a regular service call. I agreed to that because the temperature in my house probably around 40°. They gave me a timeframe for service from 5 PM to 9 PM and a service person would call when on their way. I was thrilled that Brett called me at before 5pm. Brett was very professional and thorough. He walked me through what needed to be fixed and prices. Within less than 35,minutes he replaced my broken igniter and answered questions about my desire to replace an 18 year old furnace."

"Dave was very nice and professional. Gave me a fair estimate for a new system. Brett and Jake assessed the problem and determined that there was no problem contrary to what I was told by Temperature Docs "your system is fried, your only recourse is to buy a new furnace and air conditioner" for nearly $7,000! My air condtioner started working with a tweak of a knowing plier. I was not charged a repair cost only for the service call /diagnostic which was very reasonable. I asked Brett if my system looked "fried" and he said no. I was more than relieved that the situation was remedied so easily and economically. I was impressed by everyone's professionalism and most of all honesty. I would recommend this company to anyone need heating and cooling assistance. Best of all it is veteran owned!"

"On a Cold and Snowy 2nd day of Spring 2020, my heating system went out and got really cold in the house. Called Four Seasons to come out for an immediate repair. Four Seasons was able to come out within 2 hours. Technician was very knowledgeable and fixed the the problem right away and my furnace was up and running before the freezing night came. Thanks, Four Seasons!"

"As always, Mr. Duct kept in touch before hand, showed up absolutely on time, worked efficiently, and charged a very fair modest rate. The technician also noticed one or two things that we were trying to deal with (other than the furnace) and offered solutions with the equipment on hand. Saved us another call to another place! I'll have then back to clean the a/c and do our ducts (as they've done in past)"

"Rick came to my home and gave us a proposal to remove and replace our old furnace and electric water heater. His cost was more than fair. Craig came early on the scheduled day. In no time he had the old equipment removed. The new equipment installations were all completed the same day. My experiance with C.R. Mechanical Services was better than expected. Rick and Craig were both friendly and professional through-out the whole project. I will highly recommend them for anyone in need of a HVAC contractor."

FAQs for furnace / forced air heating system install or replace projects in Mchenry, 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.
