"Shai was terrific. He discovered an electrical problem and gave me the recommendation to call an electrician and he went out of his way to expose the water heater which was covered in the closet and boarded up. I was very pleased with his work and when the electricity problem gets solved he will be back again to fix the air conditioning !"

"Replaced my gas furnace and air conditioner with a heat pump. The only company I contacted who did a thorough analysis of my home and electrical system to determine exactly what I needed. Side note: I requested this service because my furnace quit working. The technician who came out to evaluate my home repaired the furnace for free while doing his analysis. I still bought the heat pump, but this company definitely did not simply try to just sell me one."

"⭐⭐⭐⭐⭐ We had an amazing experience with Ernie from Upright Construction! He came out to check our AC because it just wasn’t keeping up during this awful heat wave. From the moment he arrived, he was professional, honest, and took the time to explain exactly what was going on in a way we could understand. What really stood out was that he never tried to upsell us or pressure us into unnecessary repairs. It genuinely felt like he wanted to help us fix the problem instead of making an extra dollar, which is so hard to find these days. Thanks to Ernie, our AC is now working amazingly, and our house is finally cool again. We couldn’t be happier with the service we received and would absolutely recommend Ernie and Upright Construction to anyone looking for honest, reliable HVAC service!"

"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."

FAQs for air conditioning projects in Moorpark, 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.
