"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."

"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 had them clear my condensate line on my AC. They showed up on time and did that work sufficiently. All is good on step one. The issue arose when I asked them to do a full maintenance check on my AC/furnace since I had been having intermittent issues with my heating coming on. And, unsurprisingly, they said that the repairs would have been in the thousands of dollars and my only realistic option would be to replace the whole unit. A few days ago I was able to completely resolve my heating issues by Googling the problem and subsequently doing a manual re-start on my Nest smart thermostat. Problem resolved by a flip of the switch and I saved 3K+ dollars by not listening to their expert advice. So, my only recommendation to anyone reading this is to ensure that when you hire big commercial AC company repair companies like Enoch, go into it with your eyes wide open. They do not pay a bunch of money for leads because they want to repair your system. That is simply the excuse to get their foot in the door. They want to find an older unit and sell you a new AC unit every time if possible. That is where the big bucks are in this business, not in repair. By and btw, I am confident that they would do a great job installing new systems. But there is little regulation of this industry and no incentive for them to just fix the issue and buy you another few years when they could cash in by telling you that your issue is beyond repair. Notice how most of their reviews here are about installing new units. That is because that is primarily what they advise everyone to do; And people trust them. Here is my expert consumer advice: 1. NEVER buy an AC/heat pump from the initial company that comes out to repair the unit and then tells you that you have no choice but to replace your unit. All you are doing is incentivizing bad behavior. 2. Get a second opinion from another AC company. If they diagnose the exact same thing, then ask for a full replacement bid. Then, advise them that they are competing. 3. Come back to Home Advisor and post that you need a new AC/heat pump and provide the exact size and model number. Then collect the bids, check previous reviews to ensure the company is reliable, and then select the most inexpensive offer. If you make them compete, you will typically save somewhere between 30-40% of replacement costs. Good luck but BUYER BEWARE."

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.
