"Eddie and Lennon are pros. They were the first company to call back after leaving a message I need help. I hired them to check the air conditioning and discovered it had a big leak. After looking and talking, the system including the furnace needed to be replaced. I decided to change the system after negotiating a price and they started to take out the old air conditioner and heater that afternoon and come back the next morning to install the new system. I asked Eddie if he could install a Nest Learning Thermostat I had purchased and he said no problem. They did cleaned up like they were never there. The new system works perfectly and with less noise too. Champion Aire Heating and Air Conditioning was the right choice to hire. Very satisfied customer and would hire them again for maintenance when needed."

"We contacted MSP for air conditioning services. Their coustomer ratings on Yelp were great. MSP was able to come out right away. The team from Angel Perez, technician, to the installers, Don and Don and those that work in the office were nothing less than helpful, kind, professional, informative and courteous. The installation process was flawless and took just a few hours. The guys were very friendly but more importantly, they made us feel confident in what they were doing. We worked out the finances which was a very simple and easy process and by the end of the day we had nice cool air flowing on a day that had temperatures in the high 90s. We are very thankful and grateful to MSP Heating and Air Conditioning. I feel certain you would be too."

"Michael was knowledgeable and very informative. The installers were competent, outstanding, and courteous. Aire Care’s bid was more budget friendly compared to other major local companies. The crew promised to get installation done in 2.5 days but completed the work in 2 days with an additional install. All in all, we would go with AireCare Heating and Air any day. We highly recommend AireCare Heating and Air."

"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."

"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"

He quickly diagnosed the issue with my unit and was able to get everything back up and running the very same day, which I truly appreciated.

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.
