"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"We live in South Florida. Last week was hellishly hot and wouldn't you know, our Trane unit went out leaving half of the house without air! The unit was 16 years old so a costly repair just did not make sense. So, mid-evening, A-Max's owner came over to measure the half of the house serviced by the broken unit and then priced out three different A/C units for me to consider. I selected a unit manufactured by a well regarded manufacturer which had a 10 year parts AND LABOR warranty. The owner performed a temporary repair on the broken Trane unit to get us through the night and departed at 11pm! I was quite impressed in all respects! The next day, the new unit (Luxairre by Johnson Controls) was installed. I was ecstatic! Until 3 days later when the OTHER A/C unit (a Lennox, just one month out of its 10 year parts warranty) stopped working. First thing the next day, A-Max called back and had a technician out that day. I decided not to replace this one, but to repair it and the next day, the technician returned to perform the repair. All is "cool" in our household now, thanks to A-Max. Talk about service!!! A-Max, its owner, his technicians and his administrative staff are top notch. And their pricing is very reasonable. Try them. You won't be disappointed. (305) 255-6671"

"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 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."

FAQs for central a/c service or repair projects in Key Largo, FL

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
