"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"Bobby was not only extremely knowledgeable but also super efficient. We did a full remodel that only had heat central air. Bobby was able to get us the right unit to add AC to our home and update our heat as well. Definitely recommend Bobby for your home heating and cooling solutions."

"Matias and Silicon Valley Air Experts were incredibly helpful and responsive through the entire project. Especially when a somewhat unexpected complication arose with my dryer vent, Matias came up with multiple options to solve the issue, and went above and beyond to make sure my apartment was safe to live in, from the dryer vent to the vents around the unit to the furnace filter. I called a couple different companies before finding Silicon Valley Air Experts, and I ultimately chose to go with them over the others because Matias clearly communicated to me the value he brought. And he delivered on that value. 100% recommend Matias and Silicon Valley Air Experts."

"I needed to have techs come back to fix 2 issues after the install, one was a loose wire connection going to the fan asm. and the other was a rain / water leak from the roof hood covering the air input / exit. In both cases, the techs found and fix the issues in a timely manner and their troubleshooting was spot on¦. The install did take time but it was impressive to watch them remove a 40 years old unit and install a new one.¦"

The team’s professionalism showed in their punctuality and quality. Every aspect was done with care, from tile placement to lighting. The transformation is truly impressive; the bathroom now feels open and luxurious. We’re beyond pleased with the result and look forward to more projects with them."

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.
