"My A/C system froze up. While searching for an A/C company to come out on Labor Day weekend I found Greyguard Heating & Cooling. They listed 24 hour service available. Jacob came out very shortly after I contacted them about repairing it and got my system cooling but made it very clear the 11 year old system needed to be replaced. I got a quote and requested it be a Rheem A/C system. They drove to Jacksonville to get the heat pump. Talk about customer service. I highly recommend Avon, Jacob and the whole Greyguard team for there professional, courteous and efficient replacement of my A/C system."

"Hired A Kool to replace my AC ducts. I received 3 quotes from different companies Company 1 - Good price but told me he couldn?t work from the attic due to lack of space so he suggested I cut holes in the ceiling so he could work from inside Company 2 - Quote 21K ? A Kool - Price was right and I did not have to cut any holes in the ceiling as they did all work from the attic. Crew was very professional, and very thorough in their work. Salesman Promised the job would be done in a day and job was done in a day. Crew showed up at 7am and didn?t leave until the job was done (8:00 pm) Will Hire them to blow insulation in the attic as they found that the attic was not properly insulated. Excellent experience."

"These guys were great! They showed up at 8:00 a.m sharp with a team of five guys and two trucks. They were all business and had the outdoor concrete Hurricane pad set and the new Mitsubishi Heat Pump installed in no time. Meanwhile two other guys were installing the 3 indoor wall air handler units and running the line sets. By late afternoon, the system was all charged with refrigerant, everything was cleaned up and all the units worked perfectly. I couldn't be happier and I'm absolutely amazed at how quite and efficient the indoor units are. They're rated at 19 dBA which is considered whisper quite; most indoor ambient decibel level is ~40 dBA. Seriously, this company did a fantastic job at a very fair price (and I bid this out to 5 other well-rated contractors)."

"Fantastic! The AC was inspected on a Monday and was unrepairable. By the next afternoon a new AC was installed and the house was cooled down shortly afterwards."

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.
