Customers say: True professional
"It went very well. Boni was recommended to us and he was so professional and helpful when we met that we did not ask for quotes from other companies. He did not disappoint. The only delays were due to delays with raw material suppliers. Once the work began, the crew worked incredibly hard and cleaned up after each day’s work was completed. Boni was responsive to all questions. We plan to continue hiring him as we decide on additional landscaping and yearly clean-up."

"Closed the deal on Friday, the next morning 5 guys including the owner Rocky were on site. They removed the old condenser and the entire oil heating system. Then installed the new condenser / heat pump outside and the air handling system inside including an air purification system. The crew was friendly and professional. They completed the entire removal, install and clean up without a problem. My wife and I could not be happier with the results. Thanks to Rocky and his team and to Greg Kim the sales rep who's impressive knowledge helped us make the right choice for our home. I give Rocky HVAC our thanks and the highest recommendation possible."

"Was happy with the service"
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.
