"Unfortunately, the air went out on Memorial Weekend. They came out quickly and diagnosed the issue but could not replace the part as it had to be ordered. Once the part came in they fixed it promptly. Here is the why I will only use them again; Rob, the tech helped me put a window air conditioner in a window to help protect my dog that has a heart condition and must be cool. He did not ask for any additional money yet invested about 30 minutes of his time to help. You do not see that occur very often any more. Thank you Rob, especially from Duke."

"Zach was very helpful. He found numerous issues with my heat pump that previous companies had not checked or informed me of. He was very kind, helping to replace the covering my copper pipes, explained how the new thermostat worked. I highly recommend this company and their people!!"

"I am very satisfied with the work done by Worley’s. I had a new HVAC system installed to replace an 18 year old system that had quit working. The price was competitive but the warranty and included maintenance sold me. The technicians that came to install my system were punctual, polite and efficient. It did take a little longer than expected due to some material issues but I was kept informed of the progress and delays throughout the process and I appreciated the attention to detail rather than rushing the job. Overall, this was a very smooth and easy process and I would absolutely recommend them for your HVAC needs."

FAQs for air conditioning projects in Williamsburg, VA

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.
