"Excellent. Max arrived on time and got straight to work. He inspected the furnace, took measurements of the air temp and cleaned all the filters. He provided some helpful information for the potential future replacement of the furnace with options and estimates. Max was professional and personable. The total cost was as quoted. Other companies I contacted either would not give me a quote over the phone, charged to just dispatch a technician, or quoted more than double."

"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"Great team. While the job is messy as they have to work under your house. Aire Serv was great to work with. We needed new ducts and boots and my house is now moving air better than it has in twenty years. Highly recommend Aire Serv."

"Mark came out to give an estimate for adding a air-conditioning/heating unit to an add-on room..He explained how the heat pump I requested wouild work and how much it would cost; I was disappointed at how much money it would take to install one, although we had received similar estimates from other companies. What's great about Mark is that he got to the real problem; it was not that we needed a heat pump we couldn't afford, but that we needed cooling and heat to that part of the house. He suggested a solution of adding duct-work to the existing system that will save us thousands. i highly recommend this man for his creativity."

"Jennifer from Air Concepts reached out in response to my Angi inquiry. She was able to schedule the service a day sooner than another company I had contacted before looking to Angi. Joshua, the tech, called before the appointment time to provide an ETA. When he arrived he quickly diagnosed the problem and was able to locate a compatible starter capacitor in his van, and replace the faulty one. I was pleased with the service and glad to have the AC working again with a single service visit."

FAQs for air conditioning projects in Alviso, 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.
