"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."

"I received two phone calls New year's day from two different companies. one of them said they would get back to me later that day with an estimate. the other one called left a voicemail and sent me a text message. so I called Craig from American insulation back. gave him the measurements of my roof over the phone he gave me a price over the phone of what it would cost to do it. I knew the pitch of my roof how many square feet my attic was etc. without going into specifics on cost and price he was $200 less than the estimate I got from treasure coast. love it insulation didn't call me back until the following day. so I scheduled appointment for January 2nd. two guys showed up I still had stuff in my attic while they were setting up their equipment we emptied the Attic. took them all of an hour to spray one end to the other. they put anywhere from 10 to 12 in of insulation all the way across my attic. they cleaned up their mess thoroughly and left nothing behind inside or outside of my home. I have referred American insulation 2 my parents. as they need to have some AC duct work done as well as insulation sprayed in. thanks to Craig for the prompt and courteous service"

"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)."

"Excellent company! We are very satisfied.We have lived in our south Florida house for 25 years. This is our 3rd AC. We were told by the other AC people that it was not possible to get the temperatre to 75 degrees in the heat of summer, in the middle of the day. So, for 25 years we have lived in AC that rose to 82 degrees in the summer. NOT ANYMORE! Comfort zone gave our home the correct sized AC and replaced our old ductwork and gave us better insulation for the attic. Like anything, there were issues that came up like one room did not get the suficient airflow and wasn't getting as cool as the rest of the house. Chris and his team fixed it immediately. Every single issue we had Comfort Zone handled it professionally, quickly and had a great attitude to help us and make sure we were completely satisfied. The best part was they ALWAYS solved the issue. We are very happy that we had our AC installed by Comfort Zone. Chris and the whole team were great. Knowing that we now have a relationship with a company that will be with us for a long time is very comforting. The picture says it all. That is at 2:15 in the afternoon at 90+ degrees outside."

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.
