"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."

Diagnosed and explain the situation and parts that needed replacement and considering part was all the way in Maryland he came thru for me and I'm very grateful for his services. Needed A/C working with this heat. Thank you Mike."

"Jonathan and his crew were very professional and a pleasure to do business with. They installed a new A/C unit at my daughter and son-in-laws home which works amazing! I hired them from Florida to do the install in California. After receiving 3 different quotes, their pricing was the best!! Jonathan was very honest and reliable and I would highly recommend Premier Heating & Air to everyone!"

"This was our first experience using Wighton’s and it won’t be the last. Aaron was very professional and very nice to work with. Our air conditioner stopped working and he was able to fix it and did some maintenance work on the unit also. He also pointed out that we needed to replace the air filter which services our hvac system, which we were grateful that he did because we had never had it changed out with a new one and it was long overdue. We signed up for their maintenance program so that our ac/heating will be inspected and maintained on a regular basis. We are very happy with his work and highly recommend Wighton’s!"

"I not only had an old furnace replaced but also had whole house air conditioning added. Very professional family business. Their estimate beat out two other HVAC businesses here in Lompoc⠦⠦ one of them by thousands of dollars. It paid to get three estimates. Daniel was easy to work with and honest. One of the other HVAC businesses in Lompoc is interested in selling you all kinds of stuff that increased his estimate by thousands of dollars. I highly recommend Ace Heating & AC."

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.
