"Bill Walker is the tech that diagnosed my faulty condensing unit compressor to be grounded. Sounds like a good thing right? but its not. You never want to hear that. Should you ever do so you want Trabuco Air handling it. I was explained what was wrong and given options that i could comfortably choose from without just breaking the the already shaking bank. Trustworthy and reliable Bill is a cool cat and confident in his skill set. He knows air conditioning extensively and will solve your needs as well. I can finally enjoy the upstairs again thanks to Bill from Trabucco Air."

"The technician came and evaluated our problem which we thought was heating and air conditioning but we were told that the heating was very good but some part went out on the air conditioning unit. He was honest and took the time to explain what we did not need and made sure we paid for only what was wrong with the unit. We are signing up for the preventive maintenance program. Sorry I can't remember the nice man's name but he was wonderful."

"Prior to me selecting Aaceâ s heating air conditioning &swamp cooler, I interview (3) other well know AC/heating company and as most knows the â deceptionâ is real! After the initial consultations with one of the companies ( (name I wonâ t disclose)I was almost in tears about how many of their technicians were out of work and that I would help put food on their table...... I reluctantly agreed and signed the contract. After further thoughts I said to myself â he got me and immediately cancelled!! Aaceâ s heating AC & Swamp cooler they were sooo amazing and I was overjoyed with happiness! Integrity, respect, excellence, and team work they exhibited wellð ð ! I'm very picky and hard too please. I had NO option but to give frank and his team the well deserved compliments they rightfully earned!!!! Without a doubt I would recommend them to my family and friends. I forgot to mention they were very clean and took all the trash away even some of mines ð ð !!!! This review is documented from a real customer and NO one asked/ suggested I write anything. Happy customer ð ð ð !!!!"

"The guys came to the house and proceeded to disconnect the compressor unit. the crane came the whole replacement didn't take more than 30 minutes. We had some problems with the air handler, only because of the space available. But the guys did it and got the replacement in. It took a long time about 10 hours. Over all we were very happy with the service and follow up service. Would recommend them without hesitation."

FAQs for air conditioning projects in Upland, 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.
