"Fontana Brothers did a great job, starting with the first time we met to get their quote. They explained everything thoroughly and gave the pros and cons for each option offered. There was no attempt to sell me something I didn't need. The crew showed up on time, they worked all day and into the night, and were very polite. They made a few modifications to our duct work that wasn't in the proposal, but needed to be done to increase the efficiency of the system, and didn't ask for a dime more. Once they were finished and left, the whole area was picked up and so clean you hardly knew they'd been here. Everything works great and we're very happy we hired them."

"Tom s service was exceptional. I had another contractor identify that my old system was leaking refrigerant. Tom confirmed the diagnosis but provided me a better deal on a better, more efficient air handler and compressor for a lower price than the other contractor. The better deal included a 10-year parts and labor warranty as no extra cost. Overall, I am very happy with the service I received from Tom. Update 8/2/21 I had a problem where my A/C suddenly stopped working. I got in contact with Tom on a Saturday night. He showed up as promised the next morning (Sunday) before 9am. Tom found the issue within minutes (a capacitor had gone bad and he replaced the capacitor). The system was back up and working by 9:15 am. Since I had the parts and labor warranty, the charge for the service call was $0 (zero). I'm incredibly happy with the service Tom has provided. I wish I could award him 10 stars."

"I needed my heat fix. Tony came over to diagnose the situation. He was very thorough. I have knee problems and was unable to go downstairs do my daughter went down with him. He was explaining and showing her what he saw. He came upstairs and showed me pictures of my unit. When he was finished, he presented me with several options. No one has ever taken time to explain my furnace. I selected a new furnace because my old furnace was too old. Thank Tony! I will definitely recommend him to service your heating unit. Thank you so much! We are getting HEAT! Thanks ABC"

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