"Great job by Rick, the team at the office Gary and Joanna are consummate professionals in an industry that has earned its jaded reputation. Very pleased as Sierra Pacific wanted to just change the unit. They've lost my business and Golden Aire has earned it! Excellent work, but honest people!"

"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!"

"Mark came out the day after I submitted an online request for an appointment. He was punctual and professional and explained everything he was doing. He had the part he needed in his truck, and he had my furnace up and running in no time. While he was here, he took a look at my air conditioner and informed me that it looked fine and was ready for the summer. These guys are honest and professional -- I was very happy with my experience."
Old AC location in front of gate and next to pool equipment. Client opted to extend the lineset and electrical saving a lot of money instead of running new power and lines.

"My air conditioner stopped working tonight. I have a heart condition that requires a cool house. Juliano came out at 9:30pm and fixed the a/c. He was professional, courteous and personable. He explained what the problem was and how he was going to repair it. Most of all, he established trust with me, which is the most important quality that I look for when seeking out companies I want to hire. Romano HVAC gave me A++ service, and I am so grateful that my home is once again comfortably cool."

FAQs for air conditioning projects in Loomis, 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.
