"Pricing was fair. The quality of the new unit is very good. They came when they promised, and did a very professional job of the installation. They were very conscious of not damaging floors and other objects in the condo. I'm very satified with the work."

"Had a wonderful experience with the gentleman that came out to fix my air unit. It was not actually the unit itself, but the ductwork that goes from one side of the house to the other was in terrible condition. Definitely needed repair. Holes in it big enough to put a clothes basket in it was no wonder that It was amazing. Their service is great so I would definitely recommend them to anybody that had air-conditioning problems or plumbing problems. If I had a chance to give them a 10 instead of a five, I would definitely give them 10 stars. Thanks again guys."

"Extremely professional, polite, and efficient! Annual Contract available for &149.99! LOVE LOVE LOVE OCEAN AIR! Highly recommend for HVAC inspection, install, repair and maintenance!"
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.
