"On July 6, 2018, when it was sizzling hot at 107 degree, my air conditioning system had water leaking suddenly. I was panicked and called all the numbers that I had of this company. It was 8:00 pm and I thought they were closed already. But in half an hour, Jake called me back to tell me he would send over somebody to solve my problem. At 10:30 Antonio and John showed up. When they finished the job at midnight, they were sweating all over. The following day Jake arranged Steve to double check. All of them were very nice. I greatly appreciate their care and hard-working. It is worthwhile to do business with them because they will still take care of the customers even after the project is completed."

"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."

My husband hired them to install a new air conditioning unit over a year ago and we called them for the yearly routine cleaning now. Their prices are competitive. They are honest. We highly recommend them."

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

FAQs for air conditioning projects in Mira Loma, 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.
