"Ozzie is extremely nice, very professional, and puts out the extra 9 yards to give his clientele good service. This would not be complete without mentioning Alberto. He installed a new HVAC unit for me. Working through the heat, humidity, lifting heavy parts both outside and upstairs, the air handler system, I would estimate he had the WHOLE job finished in 7 hours. Seems to me record breaking time, when you consider all the dismantling, carrying, cleaning up of the premises. So Ozzie and Alberto, hats off to you both!! And, I was able to go from 93° upstairs to a most comfortable 78°, perfect sleeping!! Thanks again! Hire them!!!"

"It went exceptionally well! Marc was able accommodate us within an hour of our call to him.  He was courteous, professional, and knowledgeable. He was very thorough in his diagnosis of the problem, and  ordered the necessary parts immediately. Once the parts came in the next morning, he phoned to check our availability and was able to  come back and install the parts that very morning. Upon completion, prior to leaving, he ran a test of the system to assure that it was working properly.  Marc was even conscientious enough to clean up the area before he left.  His price on parts and labor were fair within industry standards. We would highly recommend him for his services."

"A year ago they responded to an SOS related to a full A/C failure. They were prompt and professional. It took several days, in the heat of the summer, till they were able to fix it, but they had to get a part from the west coast so we sweated through the ordeal. While they were working on replacing the main board, I also engaged them to clean the system. I thought the charge was high ($1000), but needed it done. A year later, one of the A/C mini-split heads stopped working. They came the next day. I paid $200 for them to trouble shoot it, which took approximately 20 minutes. (Subsequently another A/C service charged me only $95 to trouble shoot!) They said they would order the part and get back to me. After I week, I had not heard from them. When I called they said they could get the part but it would take 4-6 weeks. I said okay. What could I say. I left it in their trustworthy hands. After 6 weeks I heard nothing from them. I called. I left 4 messages, which were all unreturned. On the 5th try, someone answered. He said he couldn't get the part. Would have been nice to know that 5 weeks ago. Still puzzled why they didn't communicate with me and thus the low review. I have to say that I thought they were really nice people, but obviously my business wasn't that important to them. So be it. But a little courtesy and honesty would go a long way when servicing a small community like Key West. Because of the later incident, I wanted to give them an F, but that wouldn't be fair. If you're lucky, have deep pockets, and the problem isn't complicated, they are okay. Just be aware. I thought I had actually found a reliable service, but that wasn't the case."

"I recently installed a Bose speaker system and the connections were a rats nest of wires and it needed to be balanced. Seth came and rewired the system and balanced the system, including the surround sound speakers in the ceiling. I had two extra Bose speakers that I wanted to use in my bedroom, so Seth brought a used Denon receiver and also provided a 15 foot HDMI cable that we needed for the set up. Seth is great to work with and he completed whole setup in the two hour time frame. I was so lucky to find him on the Angie's List.

"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."

"I was having a problem with MS Office not responding and other files being very, very slow to open. Jim started looking for the cause right away. He did numerous checks for viruses, malware, and various other things that can go wrong. He vigorously pursued a resolution pretty steadily for two days before determining it was a malfunctioning external backup system that was causing the problem. With that finding, he promptly got my computer running smoothly and very fast again. He made two trips to my house; on the first one, he had to cross a sheet of ice in my driveway. Jim is a very capable and experienced computer analyst that will get after your problem because he fully understands the importance of, and the need to have a working computer in the house.

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.
