"Project: Replaced my old furnace with a new model. I had no heat on a very cold day. Within a few hours, they put in a temporary fix so I had heat. Two days later they installed a new furnace in one day. Everyone I dealt with was polite and professional. I did not feel pressured to buy a furnace that I didn't need. The installers were great and left my basement cleaner than it was before they stated the installation! I also appreciate the follow-up call, checking to see if I was satisfied."

"Chris, the owner, was very knowledgeable about the type of furnace we needed, as well as could afford. He knew how big it should be for the size of the house. We have been using it this winter and even in the coldest period, it kept the temperature perfect. Chris did the install in minimal time and with professionalism. He even put in a flap, so that if we wanted to use our wood furnace it would close off the gas furnace flu, so the electronics would not overheat. We were very comfortable with him in our home."

"The 2025 Indiana/Ohio River flood placed my furnace and heat pump 70” under water; it had to be replaced. I called Jeff of Pike Mechanical after the water receded and asked him for a service call. During the service call, we concluded the entire HVAC system had to be replaced. Subsequently, Jeff had to correspond and coordinate with FEMA at least four maybe five different times to satisfy FEMA requirements. This took a tremendous amount of effort from Jeff who had to submit detailed pricing for every process of the job. After multiple efforts, Jeff was successful in dealing with FEMA and was able to install a state of the art HVAC system at no cost to me and completed the entire project in one day. Unbelievable! He never stopped working when he arrived and was very methodical in his efforts. I highly recommend Jeff and his company."

"From my 1st phone call to ask about the services they provide and costs to when RJ & Walker left I've been completely satisfied. My appointment time was from 1-3 and they showed up right at 1pm. RJ & Walker both walked up to me and introduced themselves with a firm handshake.  We toured the house looking at all the vents and air returns along with the furnace. Then RJ fully explained what he would be doing and the Walker explained what he would be doing. They answered all of my questions.  About 30 minutes before completing the job, RJ asked me to come downstairs and he showed me all the dirt and stuff that came out of the vents. He showed me how he closed up the intake points he had to make in the duct work. They removed the equipment and everything was put back as it was and left clean. The entire time RJ & Walker stayed productive, friendly and professional. It was a pleasure having them in my home to complete this service."

FAQs for furnace / forced air heating system install or replace projects in Guilford, IN

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.
