"They came to the house 30 minutes after calling about a broken air-conditioner. This was about 7:00 in the evening. He was able to find the problem and repair it in approximately an hour. I was very relieved that they could fix it, without replacing the compressor. Great service and very professional. I feel the price was fair for an evening service call. Thank you Jason Daniels.

"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."

"First, John Page (the design consultant) was there when promised. He was very knowledgeable & took the time to really explain things & their procedures to my Mother & I which made all the difference in making a decision on whom to go with on this journey... I call it a "journey" for these reasons: Out of the 3 other companies we called here in the Keys, not one of the seemed to care enough to spend the time & effort Ellington did, & when we asked about extending our warranties & maintenance etc. nobody had anything remotely close to offer compared to the Ellington "No Worries" program wheras they take care of EVERYTHING & the best part is there are ton of benifits no one else even offered w/no exclusions for 10 plus years. They also offer a 180 day money back guarantee in writing so for those reasons it was an easy choice! The installers were punctual, clean cut & very nice on top of truly demonstrating what was extremely important to us which was true craftsmanship. When making a purchase of this magnitude we know from past experience, it is not necesarily the equipment itself that is so important, it is the installation & setup that is even more important. After all work was done, a quality control audit was performed to assure us the machine was giving us all the efficiency it is supposed to & the ductwork was indeed installed per Johns drawings & sealed air tight as he promised. It passed with flying colors! My Mother & I would certainely recommend Ellington AC to anyone tired of a slick talking salesman that promises the world & then it does not go as planned... Probably the most professional company I have ever dealt with down here, Thank you so much!"

"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 air conditioning projects in Key West, FL

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
