"The service person was on time and performed the work efficiently. The 5 air conditioners are not central units, they are mini splits, with two installed at a height of 15 feet in the wall. The degree of difficulty is challenging. They were cleaned and the exterior condensers were checked for levels. All seem to be working properly."

"We needed an central air conditioner in old town Key West. Our current wall units were very noisy and inefficient. I received multiple quotes from different contractors for the same Mitsubishi mini split system. American Cooling was the lowest price and we proceeded with the install. The installers were extremely professional keeping the mess to a minimum and ensuring that it was cleaned up after each days work. The install was completed in a day and a half and once complete they made sure we understood how the system operates. We had a minor issue with one of the wall thermostats and they came by the following day to resolve it. I also received a call from Dan just to ensure that I was happy with the work that was performed. Mel, in the office, is funny and a pleasure to talk to. I highly recommend speaking to them for your AC needs."

"They installed a dual-zone Mitsubishi mini split system in my home, did a wonderful job! Best purchase I've made, I love my mini splits. They are quiet and cool the house in a short time, they look great and were installed professionally with required permits. Highly recommend this contractor for all AC installations and services. They've serviced and cleaned them as well, came with a 12 year parts warranty. I will not let anyone else work on my AC!"

"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."

"We called Keys Mechanical to look at our central unit which was making sick noises and obviously struggling to cool our home.  We called them based solely on the Angie's List reviews.  As anyone who has lived in the Keys for any length of time knows, just getting someone to actually show up is a feat in itself let alone someone who is competent to do the job they claim they know how to do.  My husband called, set up a time for someone to come look at the unit and then we waited to see what would happen.  Low and behold an actual AC guy showed up, a little late but he did call ahead to let us know he was running behind.  In our experience, this in itself was remarkable.  It is not unusual for contractors/workers to show up late - after all everyone is on Key West time - but it is usually that they show up as much as 2-3 hours late without the courtesy of a call, explanation or God forbid an apology.  Oftentimes they just don't bother to show up at all.  We often wonder how they keep their businesses going without doing any work.  Anyway, they showed up, performed a diagnostic, gave us the bad but not unexpected news and then proceeded to put a "bandaid" on the unit to bridge the time between getting a new unit.  Gave us an estimate, told us the cost of the day would be erased if we purchased our new unit from them.  We did check out one more source of a new central ac unit; the differance in price was amazing.  In the meantime the "bandaid" while not perfect is certainly keeping us comfortable enough to sleep at night.  We will be purchsing our new unit from them; at that time will probably write another glowing review.

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"Of all the companies I called, this was the only one that answered all my calls and was consistent in following up with the status of the repairs. This company served all of our needs even in the middle of the holiday season. They even brought an emergency air conditioning unit for my dad who is ill. THANK YOU!"

Air Conditioning FAQs, answered by experts

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.
