"We had several issues over the summer with our AC unit and Waylon was very responsive to our service requests. Diagnosis showed we needed a new system. I had issues on my end nailing down a solid install date, and he was very accommodating to my changing schedule. Install of the new system was fast and professional. They left the worksite immaculate, and removed all old items. Waylon and his team are true professionals and I will recommend to anyone who needs any HVAC work done."

"William A/C & heating came out within the day I called to report our air-conditioning unit was not working. Once the technician arrived he did an on site evaluation and got the unit running in short order. He took the time to show me what work was needed and why. This is a family owned and run business that provides honest, professional, competent and timely service. I highly recommend Williams Air Conditioning and Heating.

"Chad, the Consultant is very knowledgeable on the functions and efficiency of the different systems. Very thorough explaining the levels of efficiency, pros/cons, etc. The level of service during the consultation was exceptional, and surpassed my expectations on the initial consultation from other local companies I reached out to for estimates. His thoroughness gave me confidence that the installation of the system would be just as exceptional. The company extended some courtesies I was not expecting prior to the installation. The installation was just as good as I was assured. Mr. Alexander, the owner, was at the house at the beginning of the installation to ensure everything was good and as expected. The team was considered, focused, thorough and very patient and respectful with my questions. They worked expeditiously, and did troubleshooting at the end to ensure it all worked properly, then cleaned up all the areas prior to leaving. I am very impressed with the service and overall quality of the work. I am very satisfied with the end result, and feel very grateful I did not settle with the other estimates I received from the other A/C companies. Based on my experience, and how selective I can be, I consider Alexander Air Conditioning a first class business and highly recommend it. I want to publicly thank Chad, because in my case, he was the face of the company, he represented well, he was genuinly interested in educating me, which resulted on my decision to select this company. I also want to thank the installation team for the detailed and high quality work they performed! Thank you!!!!"

"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.

FAQs for furnace / forced air heating system install or replace projects in Wausau, FL

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.
