"My wife and I were throughly impressed with the professionalism of the company and their installation crew. They were meticulous in their work practices and went out of their way to keep us informed of the status of our air conditioning project from planning to completion. It was truly a pleasure dealing with such an honest and ethical HVAC contractor. Michael Santana, along with his talented team of Enrique and Raul more than exceeded our expectations with their outstanding work and customer service. We solicited quotes from numerous contractors and Aire Care Heating and Air Conditioning hands down provided the best cost and installation proposal. If you are looking to replace your HVAC system, I highly recommend that you contact them."

"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."

"Very in detail description of what needed to get done and the why behind it. Awesome job, professional, answered every question on why my central AC was strong on first floor but very weak in second floor. Air handler moved from bottom floor to upstairs attic, higher capacity central AC and all ducts changed. Beautiful work done in 3 days with detailed report of what was done. Fair price for the job done. Before and after."

FAQs for air conditioning projects in Corona, 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.
