"My experience could not have been better, every time I needed Ariel. More than once my medical practice has had air conditioning problems and he has done everything he could resolve the situation as fast as possible. The same has happened at my home. I have the utmost respect for him and his business. He is efficient, very responsive and his price is very fair. He has never disappointed and I think anyone can expect the same outcome!!"

"I was not sure what was wrong so I called these guys, described what I knew, and they said they would come look at it. They said there was an $85 minimum charge for an assessment but that it would be credited toward any kind of services and equipment that I needed. They showed up within 2 hours and even called me ahead of time to double check that I would be there. Once they arrived they checked several things before opening up the unit and then showed me where the electrical part of the system had melted, likely due to a power surge. So it had to be replaced, but they said they could replace the whole system (inside, outside and thermostat) that day. They even got a crane because the outdoor unit is on the roof of my condo unit. The techs were all quick, polite and respectful. They also helped provide photos and documentation should we need to submit a claim to the homeowners insurance company. I would highly recommend them and would use them again in a heartbeat. Big thanks to Alex Rodriguez and his team."

"Core Mechanicals' tech Jason came in and inspected our A/C system. We had problems with it freezing up. They checked the pressures and added refrigerant to fix that. They did an inspection of the entire system and found our air handler to be extremely dirty. He removed the handler and brought it outside where he thoroughly cleaned it (it took a couple of hours to do. It had a lot of dirt and hair. It was really gross to see that was where the air that my family and I were breathing in came from!) The system is almost 5 years old and he removed the dirt and hair that had accumulated in it over that period of time. I highly recommend getting that done by them! The air quality in my house is so much better now. My family's allergies have been so much better, especially with the dog in the home. My system works and cools much more efficiently and they showed me how properly install the filters, that is very important for capturing dirt and dust. So worth the cost! Cleaner air and my electric bill was even a little less! Jason was very informative and explained the workings of my system to me, I never really gave it much thought before. I am having them back out to install UV light/ air purification system. I highly recommend them! Very prompt, knowledgeable service, very professional! Jason said he works from Key West all the way to Key Largo, and works on all brands. I believe they are a Lennox dealer and they also do pool heaters. They are my A/C guys from now on!

"I had debated installing a new system for months. I shopped around; looked at reviews; and decided to go with Major League Contracting Services! The owner, Laz, came from Miami to my home in West Delray to give me an estimate. He said my current unit was too small, and that after 12 years it was time to replace it. We agreed on a price, and set an installation day. They came up on a Saturday and installed my new "York 3.5 ton unit." The air handler is in my attic so it was a tad tricky. After a couple of hours the unit was installed! The installers were very quick, informative, knowledgeable, and polite. Laz even came up and explained the work and even offered to file my registration with York. If you want to work with a local company that goes above and beyond to provide excellent service as well as a competitive then Major League Contracting is the company to use. Call Laz today at 786-344-1846."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

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