"Sierra Air is the best! their service techs are professional, knowledgeable and genuine! I called in the morning about my AC being out and I had a tech at my house that afternoon. Michael was amazing and took his time to show and explain everything to my husband and I. Turns out our unit needs replacing and Michael put in the calls to have Sierra air call us and schedule a person to come out and give me and estimate. I got a call THAT DAY! I’ve been a customer for two years and with customer service and satisfaction like this I will continue to be."

"They sell to you a filter to your furnace that is metal that is supposed to be a strong benefit over the throw away kind. This is kind of controversial. You have to take it out and hose it down. I stopped using it on the advice of my air conditioning installer."

"We had several issues that caused us to contact a company that can come over and check our house for any problem that can be solved and reduced our utilities bills. We contact this company and we asked them to come over and see what they can do. Avi came over and explained to us how they work and what they do in order to determine what can be done. The initial work included sealing all the openings in the house and then they made some tests with special machine that made a clear picture that our air conditioning system have some leaks that causing the system to work extra time. After they completed the testing, Avi came over with another crew of workers and fixed the ducts making sure that there will be no more leaks from that area. The work that they did was good because they made a massive testing before they came to the conclusion about the air conditioning ducts.

FAQs for air conditioning projects in Portola, 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.
