"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."

"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."

"They sent me a guy who was probably did plumbing for ten or fifteen years. Heating and Air conditioning, he did about three years. I had the heating and air conditioner for twenty years, and also bought this unit. The price is really high for an air conditioner. $12,500 if you want it down right. $4000 in the attic. It was $16500 investment. He didn't have what I wanted to hear. The gauges to calibrate anything. Nothing needs calibrating and told him the problem with the thermostat, and since he left he just turned it way down, I am trying to get eighty degrees, and keep it normal temperature. He is trying to get seventy eight, seventy five. Certainly its going to pump a little more colder. He didn't give us a reason why that thermostat isn't working right in the afternoon. He didn't have that answer, or the reason that you could adjust it. Can you adjust that? He had no idea of any adjustments of the thermostat. I didn't ask. I wanted to keep it all the same. I don't know, he didn't had the experience in heating and air, but he had the experience in plumbing. He didn't, and what he wanted for $85, its steep for me, when I just paid $16500, and for the attic ventilation system. I thought he would say $50 or $60. I paid him, and I went to Right Choice to do everything, complimentary. Something to help us out. I didn't ask them, but I would hope they would offer. He wasn't knowledgeable, and didn't know the answer. He wanted a $1000, it takes care of maintenance. Like he just came to the house. That is what he wanted to sell me. I gave him an soda pop, and wanted to see what he wanted to sell me.They sent an really knowledgeable installer. The parts are all knew. I would think they would have followed up, but nothing. Maybe that isn't a lot of money. I wrote a $12,250 check to them. Its a lot of money. I would want them to come out and make the air flows correct."

FAQs for air conditioning projects in San Bernardino, 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.
