"We have been using Golden Aire for maintenance and repairs for the past 8 years. They are professional, knowledgeable and courteous, as well as fair in their pricing. Case in point, we had Daniel come out to do our summer A/C maintenance. Daniel discovered that coils were bad and leaking coolant. We received our quote for the parts and repair. The cost was estimated at $3k (ouch!) Parts were ordered and Daniel came out within a weeks' time. I can't state highly enough how impressed we were with Daniel's knowledge, professionalism and most importantly care. Daniel was able to save us $1,300 as he discovered that after fixing the Nitrogen leak and replacing the refrigerant there was no need to replace the coils. I know other less scrupulous companies would have milked us for a higher invoice price especially since the coils were ordered. Thank you, Daniel, and Golden Aire for your honesty and professionalism."

"Brian initially came out to repair my existing broken AC unit. He went over what was wrong, and that being over 20 years old, the AC unit was going to be more expensive to maintain and may not run for very much longer. Brian was upfront with all of the costs for a new unit, which we decided to go with, and gave a very reasonable price for the service. Brian and Angel came out and got the job done quicker than expected. They will be my go-to for heating and air from here on out. Highly recommend!"

"The experience was fantastic! I never thought I'd say that about a furnace installation but the 2 servicemen Dmitry and his colleague made me feel very comfortable with all the proceedings. The last time I had to replace my central air system was different. The gentlemen doing the job were dismissive of my requests and ended up setting it up wrong having to return several times to finish. Nothing like that with RK Mechanical, super smooth sailing."

FAQs for air conditioning projects in Rocklin, 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.
