"Phil's team did a great job. They were punctual. They kept their work area clean, and left the place looking like it did before they came. The guys were professional, and Phil followed up with me at my home after the install to do a final inspection of the work. Phil got me significantly increased air flow for a marginal additional cost. This was probably the best part of the service. He understands how to maximize the system. I will definitely use Energy Sharks in the future, and I have already recommended them to others."

"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.

"First HVAC contractor wanted to replace the unit. Island Climate repaired unit for less than $100 and it has been working since the first hurricane at St. Helena, SC. Then had Island add a 2nd system for the 2nd floor which has worked well."

"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!!"

FAQs for furnace / forced air heating system install or replace projects in Allendale, SC

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.
