"Mark came out the day after I submitted an online request for an appointment. He was punctual and professional and explained everything he was doing. He had the part he needed in his truck, and he had my furnace up and running in no time. While he was here, he took a look at my air conditioner and informed me that it looked fine and was ready for the summer. These guys are honest and professional -- I was very happy with my experience."

"Glenn Julian, the owners son, arrived within the expected time window. He allowed me to watch as he explained the various tests of the air conditioning that he was doing and he also described some of the previous experiences he has had with air conditioning systems. He seemed very knowledgeable and experienced. He finished the air conditioning maintenance check within one hour. We plan to call Julian's Heat & AC again in the fall when we need to have the heating system maintenance check done. Thank you Julian's Heat and AC for a great job done!"

"My air conditioner stopped working tonight. I have a heart condition that requires a cool house. Juliano came out at 9:30pm and fixed the a/c. He was professional, courteous and personable. He explained what the problem was and how he was going to repair it. Most of all, he established trust with me, which is the most important quality that I look for when seeking out companies I want to hire. Romano HVAC gave me A++ service, and I am so grateful that my home is once again comfortably cool."

"I met Jesse (owner) at the Auburn home. After setting an appt., he showed up on time as promised (can t say that for a lot of other companies). We reviewed what I wanted done which I appreciated because I ve had others suggest what they wanted done instead. He physically went up into my attic to access my old and inefficient insulation, including video recording it. He also spent time looking at my old windows (1980 s style) that I was also looking to replace. Jesse came up with the cost which was thousands of dollars cheaper then the several other estimates I have received. After agreeing on moving forward, Jesse played an active part in the entire project. He even provided me with his cellular number and always got back to me when any questions arose. The workers who came to install the insulation were very friendly and professional (I continuously talked to them, probably annoyingly). They took their time to assure that everything was done as promised and I even double checked their work. The next part of the project included a new slider and several windows. Jesse was on scene throughout the window installation and the final product was fabulous. Craftsmanship was impeccable and the windows and slider look great. Even after the project was complete, Jesse has contacted me to assure full satisfaction was met. I would recommend Clear Efficiency to anyone."

FAQs for air conditioning projects in Penryn, CA

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.
