"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.

"They did a wonderful job from beginning to end - were mindful of our budget and did not recommend more than we needed. They also offered a great financing option. The HVAC contractor arrived as scheduled, completed the job quickly, and cleaned up completely. The furnace has been in operation now for over a month and we have had no problems."

"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.

"It took a round of phone tag, but a date and time for the job to be done was set within a few days of my initial contact.  They explained that they planned for the work to be performed that day, but the workman would evaluate the cracks/leaks and if it could not be repaired properly using the material he had with him, that he would either give me a quote at that time or set up another time for someone (Joey)to come out and evaluate the extent of the repairs required and determine the best method for repair and give me a quote.

Joey arrived on time and ready to work. Since my basement walls have a number of surface cracks, he asked me where the biggest leaks were. Since I had purchased two deals, I showed him the two cracks we wanted sealed. He then got right to work and explained how the system and sealants they used are superior to what is generally available to homeowners.

The system he used, utilizes an expanding foam system which was pushed into the cracks under pressure by ensuring that the only way the foam could expand was into and through the crack. The cracks I had were irregular and one was actively leaking, but he was able to access the cracks and perform the work on the foundation/basement wall entirely from inside the basement.  First he cleared an area around where he would be working, then he drilled a series of holes into the cracks to insert the filller tubes and then completely covered the remainder of the crack with pneumatic cement. Joey then produced what looked like a giant syringe (believe me, if your doctor came towards you with this syringe you'd get better in a hurry and run the other way!). The "syringe" actually had a division in the center with a different material on each side. As it was set into their filler tubes and pushed in, the materials mixed and started to react and expand. I asked Joey why they didn't use a machine to push in the material and he explained that they do have machines like that on the market, but a machine doesnn't "feel" when the correct amount of material has been put in and they often blow out the patch. Well, Joey had the touch.  You could see the amount of material that came out of each filler tube after epansion was complete and you could see that each had been filled completely but none had been grossly overfilled. On the second crack, the system proved itself... the material started coming out of the wall from an area where I had barely even seen a crack and that was about a foot to the left from where Joey was working on the main crack. With that combination of expanding material and manual pressure, the foam followed the microcracks within the wall to that fine little crack a foot away... I was sold, then and there!  He explained that the nature of the material allowed it to spread through adjacent cracks while it was still in its initial, liquid form under the applied pressure. As the minutes pass, it then becomes a soft, then a stiff, foam, then finally a solid. 

Once the product had set, Joey cleaned off the excess and swept the work area. He went over the warranty with me and also made sure I knew about all of the company's other products/services. Lastly, he gave me some cards so I knew how to contact the company, and he had me sign off that the work was complete to my satisfaction ... which it certainly was!

 A couple of weeks later, someone called from the company to see if the cracks were fully sealed and if there was any seepage or any other problems that needed to be addressed.  To date there hasn't been any further leaking or seepage.  The repairs remain solid.,"

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