"I recently moved into a rental that was not taken care of by previous tenants. I had sinus issues the moment I moved in which lead me to find a hvac company to come clean the ducts. I was able to schedule a service within 2 days of the request. Ken was an exceptional tech who serviced this home. His attention to detail has now made my home more enjoyable to live in and my sinuses are no longer an issue. The sanitizer he sprayed in the venting system is what sold me on this company. Very pleased with this company and Kens service. I hope I save someone the pain of searching, like I did. Look no further, I would highly recommend using them."

"We had Fontana Bros. replace our complete HVAC system. They were professional, reliable and easy to work with. They coordinated flawlessly with our condominium association. Our HOA required that a crane be used to place the compressor unit on the rooftop and Fontana Bros. handled all the details skillfully. The technicians were extremely polite, professional, competent and knowledgeable. We are very happy with their services and recommend them without reservation."

"We had a repair completed in August by another air conditioning company. They recommended a repair that would have cost an additional $3,100. After 3 phone calls to the other company and no response, we received a flyer in the mail for Southern Comfort One Hour. We contacted Southern Comfort One Hour and agreed to a maintenance contract. The technician recommended we consider a new air conditioner. We agreed and the meeting with their sales professional was great. He offered a system with a great warranty, efficiency rating, and air cleaning system (Both my wife and I have allergies). In addition, the price of the system was a great value and they installed it the next day! The installers noted some inefficiencies in the duct-work of the old system and corrected them to improve the airflow of the new installation. Great work and very professional staff."

FAQs for furnace / forced air heating system install or replace projects in Cortez, 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.
