"We recently moved into a house built in 1987 with the original air conditioning unit, which constantly ran without stopping. It was a brutal summer, but it was definitely not running properly. Joe came out himself to take a look. He took a look at the entire system and suggested that we service the AC to make it function properly and not constantly run. He also changed the air filter in the furnace. I appreciated the fact that he did not push a new air conditioning system in the house considering the unit we have is 25+ years old. He also gave us a few ideas on how to make our home more energy efficient. He did a great job.

"Simply outstanding. I had been using another company I will not name here, but looking over the HORIZON for help since they could not service my Air Conditioner until August, I turned to Home Advisor. Desperate for help, low and behold up popped Mechanical Monster. Expecting another July/August response, I spoke to this very nice lady, and she said the owner Jeff had an opening the following day! Wow! I was still a bit leery but Jeff showed up, explained to me everything he was doing, made me feel at ease. He found the problem, went above what a normal repairman would do and said you will have Air Conditioning tonight. He was out in the dark, in the rain, getting done. I have not had customer service like that in probably over 30 years. This is a great example of what America used to be, companies going the extra mile to satisfy their customers. This is rare in these times, and I am really blessed to have come upon Mechanical Monster and Jeff. Renews my hope for our great country that there still are companies out there to put their customers first."

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.
