"We chose repair of a very old air conditioning unit due to the cost of a new unit. It is working now but we have no guarantee of for how long. Global responded quickly and repaired the unit within hours."

"I found Alanis Air through Angi/Home Advisor because we were having HVAC issues in our new home. Our 4 year old system would turn on for only a few minutes and then stop. I believed it was a wiring issue, but it happened to be a short in the condenser. Alanis Air replaced the parts promptly. I was also concerned that part of our remodeled house could be cooled better.. So after exploring options (i.e. adding a second system, ductwork redesign, adding a mini split ceiling cassette, or wall mount) we decided to go with a Fujitsu wall mount. Alanis Air also carved and framed out an attic access in our closet where the remodelers shouldâ  ve put one but didnâ  t. They patched and painted free of charge and did a great job. I highly recommend them."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"I found Jim's Air Systems through HomeAdvisor, and Josh was the first contractor to reach out to me personally, not through an automated service. From the start, communication with him was excellent. I provided him with a detailed description of the job, along with model numbers and photos of my existing system. He reviewed everything carefully rather than giving me a quick, generic quote. I received another bid for comparison, but the other contractor was significantly more expensive and wanted to upsell me. It was refreshing that Josh understood I had done my research, knew what I wanted, and didn't pressure me into unnecessary upgrades. Josh's team arrived on time, completed the work as scheduled, obtained the required permit, and left my home as clean as they found it. Overall, a great experience and a solid value. I wouldn't hesitate to recommend them."

"Jaleel Porter from Bell Brother's Heating and Air, Inc. came to the house to install and trouble shoot the installation of two Ecobee Thermostats. We prepaid Best Buy's Geek Squad to installed them but their electrician was not able to install them properly. The job was abandoned by Geek Squad leaving some HVAC wiring mixed up and at least one wire was not connected properly. Jaleel Porter was courteous and has represented his company extremely well. He came wearing protective mask and shoe coverage. He was knowledgeable about the product that he installed. He was also informative about any general and specific HVAC questions and maintenance issues. Moreover, he was also punctual and cordial in communicating how the service works. He was also patient and helpful in teaching us the settings and operations of the system using our apps. He did not leave the premises until everything was functioning properly. Finally, There were no "surprises" and the price was reasonable and competitive."

"Truthfully, we had angst about calling for service because of past experience with other HVAC vendors. They always said the same thing, our system is "old" and we need a new one. Very expensive! We called for service, not a hard sell! Hence, we never used the same one twice. However, Tyndall gave me the impression, whether right or wrong, that they would be less likely to do this so I decided to try them. They kept me informed of their arrival status, since they squeezed me in at the end of their work day the same day I called. So, communicative and accommodating! After running several tests, they determined it was an electrical problem and nothing to do with the unit itself. They also said our unit doesn't need replacing - that's a first! They didn't do any unnecessary service or repair to run up the bill or even try to convince us it was needed. We were only charged the minimum fee as quoted. We were able to repair our air conditioning without the "hard-sell angst". So, thorough and honest! Unlike the other HVAC vendors we've used, we definitely will call them if we need service again!"

FAQs for air conditioning projects in Berkeley, 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.
