"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 bought my heating and air conditioning systems through Perfect Star, and use them for a heating, and an air conditioning tune up each year. They work is exceptional, as are the employees. I have recommended perfect star to friends, who all were more than satisfied."

"Said fixed the leaking pump but noted that there were some hazardous conditions caused by the way the unit was originally installed. Suggested that I call PG&E for a safety inspection. Did so and they confirmed that there were indeed small gas leaks due to faulty and ancient installations. PG&E did repairs and I am getting proposal for repair of the 90 year old gas lines. Really appreciate Said's thoroughness and honesty. Could not recommend anyone more highly!

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

"My air condioner coils were freezing up and there was water around the unit near the drain line. Tech checked everythign and stated that there are no problems and that the drain line probably needs to be cleaned out. He spent about 90 minutes but didn't actually service or repair anything so I expect I will still have the coils freezing up and the water leak. Nice to know the unit is up to pressure and all, but it would have been nice to have him address the issues."

"From our first conversation to finishing my Heating project, Comfort Home Heating and Air was full on fabulous. Juan knows his trade very well and led me through my questions and decisions. Once we agreed on the project and date, Comfort Home showed up on time and seemed to use every moment effectively, by being Systematic and organized. They cleaned the area around the Heating and Air unit so it looked better than before. I can tell by looking at the installation that things were done thoughtfully and cleanly. I have worked with many contractors and have never come close to the satisfaction... even pleasure I had with Comfort. I cannot think of anything Comfort Home Heating and Air could have done better. I highly recommend them, if you want the best."

FAQs for air conditioning projects in Emeryville, 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.
