"When we woke up this morning, the furnace wouldn't come on.  We called Bob Ondrey of Advanced Air-Heating & Cooling.  He was on another job, but responded quickly and came to our house the same day.  The problem was the ignitor.  We have had him before and will call him again whenever we have heating or cooling issues.  We have been totally satisfied every time we have had him. Highest recommendation.

"Installers arrived a little late, however the installation went very well. They explained what they would do and aswered any questions I had. After the installation was complete, they gave instruction on how to set the thermostat and what to do to care for the furnace. Overall the experience went well and I would hire Sears again."

"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

"We had many issues with our computer - primarily with the CD/DVD drive and iTunes. Jim eliminated over 700 viruses from our computer, which was just the beginning. There continued to be problems within the systems of the computer. Luckily Jim charges by the job and not by the hour because he worked a LONG time to make it all work.  He kept in touch with me and addressed each issue as it arose until the job was done.  He was professional and courteous and hung in there until I was satisfied he had addressed everything. I would highly recommend Jim and will definitely use his services in the future, as needed.

"The furnace is functioning properly! However it was discovered that the air conditioning fan did not come on and it caused an error in the thermostat and shut down the system. The repairman got the fan going but when he left the same system malfunction happened again! In talking with the repairman, he needs a day that is warm to be able to perform diagnostic tests. It does not look like we will have warm enough weather for at least 2 to 3 weeks!!"

"We contacted crawlspaces.com for an estimate to waterproof our crawlspace. The estimator, Brian, was very professional and friendly. He explained in detail what the job entailed and how long it would take to complete it. It was a pleasure working with him. We agreed to hire crawlspaces.com. The crew chief, Javi, and the rest of the crew were very professional and friendly as well. They treated our property with respect, as if it was their own home they were working on. The finished job is such a GREAT improvement to our crawlspace. We now have a cement floor crawl instead of dirt and gravel and also the entire walls of the crawl were sealed and spray foamed. They also installed a new sump pump. There is tons of storage space and its also a clean and healthier crawl. We have already noticed that our floors in our home are warmer! I'm sure with the winter coming we will also see a difference in our heating bill. The only regret we have is that we did not contact crawlspace.com to do the job years ago."

"Called warranty repair, found out that it was done by a local provider (Flori Heating and Air). I called Flori to schedule an appointment, they were here on time and got things back up, running and cooling. Since it was 95 outside, I appreciated their sense of urgency and calm professionalism, not to mention the quick return of cold air coming out of my vents!"

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