"They do the annual maintenance on my air conditioning system, and they sold it to us. They installed my air conditioner about ten years ago, and they come out every year to do the annual maintenance on it; and if anything goes wrong, then they come out to take care of it. I had a problem this year, a couple months ago, and that's why it's kind of like out of the cycle, but usually it's at the very beginning of summer, just before summer, early in June that they come out. That's been for every year the last ten years. I'm on a contract for the annual maintenance type thing, and to the best of my knowledge the price is in line with everybody else's. The annual service I think is like $60 or something. They come out, they service it, they check out everything, they redo the grillage if it's necessary. They just make sure that everything is working fine. I think they're very knowledgeable about the products that are out there. They give you good information to help you make your choices as to what's going to fit your needs. They are prompt on service. They're reliable for their annual contracts. They come out. The only thing is that they're a little bit slow if you don't get everything done on a visit. If there is something you have to follow up with them, they're a little bit slow with thatA"

"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."

"This is not a duct cleaning! They merely spray a chemical into the air intake to "sanitize" the ducts. The upgrade to duct cleaning is $65 per duct. I have 15 ducts!!! Very informative transaction. No complaints

"It took a while to discover and address all the AC issues, but it was same day service and handled in a satisfactory way. We would call them again."
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.
