"Excellent installation and service. Our ac was having major compressor problems and we had little dehumidification. TruAir installed a complete Trane ac in about 6.5 hours so we hardly notice the shutdown of the old one. They did a great cleanup and Collier County came today and approved the installation with no exceptions. On the day of installation, one of the owners spent a lot of time explaining how the thermostat worked and we were very appreciative of that. Very happy I chose them."

"If anyone is considering using another company. DON'T. I called Conditioned Air, the following day the guy tells me all my duct work I'd bad and needed to be changed, he also told me my existing a/c was oversized and his quoted price was for a smaller unit. 3 days to do the job price $13000. My next call was to Comfort Air. The following day the guy tells me that the mixing boxes are to small and need to be replaced, he never mentioned going to a smaller unit but tells me the fan on my air handler is cavitating. Are we talking about a boat? 2 days to do the job. Price $ 10500. Called American mechanical I spoke to Kenny he had the warehouse manager Marshall arrange for Jerry the appraiser to be at my house same day, 2 hours later Jerry arrived looked at what had to be done. He said ductwork was fine, mixing boxes were fine and let's just say we had a good laugh about the fan cavitating. Price thousands less than both of the other idiots. Doug and Mike the installers were great, explained everything they were doing, answered all my questions, left my garage cleaner that it was. They installed my A/C as if they were working on their own house. They had to trim bushes to install my condenser they trimmed and cleaned up better than my landscapers . From start to finish the job was done first class. I don't usually write reviews but American mechanical deserves 10 stars. Being disabled I appreciate knowing that the job was done by honest people who were not looking to take advantage of me. Thank you all!!!"

FAQs for air conditioning projects in Marco Island, 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.
