"They were great. I asked for a couple services, and they recommended that I hold off on the second service, until the summertime. The air conditioning would be really tested in the summertime, so they will honor the deal in the summer, when its really needed. I thought that was fantastic. They didn't initially call me back right away, they lost my number, but they corrected the issue. He was on time exactly. Very courteous. Summer I am getting another cleaning, and they said they would honor the deal. They honor the deal. They went above and beyond, The deal was for one service, and they honored it for two. Went above an beyond, and courteous. Very reputable, didn't overcharge. They didn't up sell, you get what you ask for."

"Very in detail description of what needed to get done and the why behind it. Awesome job, professional, answered every question on why my central AC was strong on first floor but very weak in second floor. Air handler moved from bottom floor to upstairs attic, higher capacity central AC and all ducts changed. Beautiful work done in 3 days with detailed report of what was done. Fair price for the job done. Before and after."

"This was absolutely the best service I could have imagined. My vents went from filthy to spotlessly clean. I feel as if I can breath again. The value for the services provides was excellent. The technician, Elie, was fantastic. He was so service oriented and treated my wife and I like his own family. He worked with us on pricing so it was affordable and he gave us a ten year "club membership" for only $999.00 which gives us ten years of maintenance, twice a year for the next ten years to keep our heating and cooling systems updated and clean. I strongly recommend The Right Choice Heating and Air. They are fantastic. Thank you, Elie, for everything and keeping my family healthy! You're the bomb!"

FAQs for air conditioning projects in Fountain Valley, CA

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.
