"He serviced my air conditioning unit, took care of two leaks in the unit and replaced my old thermostat. The unit itself works better than it even did when it was first installed."

"The company is top notch professional from the minute we met them. From the contract negotiations, delivery of materials and instillation, they were amazing. The installers gave us good advice about where we thought the unit might go to be placed in a more efficient noise cancelling area. I recommend this company to anyone who has air conditioning needs."

"I recently had a Daikin AC system installed in my home and I couldn’t be happier with Piggies Air Conditioning’s service. From the very beginning, Ruben was extremely knowledgeable, thorough, and informative—he made everything clear and easy to understand. The installer, was just as impressive. He was friendly, prompt, had high-quality workmanship and left the workspace immaculate. Piggies’ quote was competitive AND they offer AMAZING WARRANTY!! Overall, I was completely satisfied with the entire experience and would absolutely recommend this company to anyone looking to replace their AC unit. By far, the best family-owned HVAC company I’ve ever had the pleasure to work with. I appreciate their top-notch teamwork!"

"Tim with Efficiency Air out of Ventura, Ca was great. I selected Efficiency Air after receiving three bids. Tim personally bid the job and followed with a second visit when I informed him of my decision to award the bid. Tim was on-site during the entire installatIon. He and his crew replaced my heating and air conditioning units plus new ductwork in less than one day. I was very impressed with his approach to planning the job and executing every aspect efficiently. I would definitely recommend Tim Mitchell to anyone."

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.
