"Chance did a great job for us. Arrived on time, removed the old tank and installed the new water heater in 2 hours. Chance and his helper were very professional, efficient, and cleaned up the work area. I would definitely hire Best Chance HVAC again."

"We highly recommend the team at McDonald Home Solutions for your HVAC needs. We were 100% satisfied with the work that James and Vince did. They were on time, professional and a true pleasure to work with. I appreciated the time that Zach spent with me explaining the ins and outs of what unit would work best for us. The quote we received was very fair. #veryhappycustomers"

"Excellent all around. One Hour, the other Marin county heating and air conditioning company tried to rush me into using them at a price that was 2x over market. No rationale for this at all and they just wanted to soak me for a huge price increase. Moore came in at the correct price and no pressure."

"Overall, the project went very well. They did push our initial installation date back by 3 weeks but once here, they put in the hours to get it done in a timely manner. I especially appreciated the professionalism of Keith, Pedro C and Kody M. They put in 2 new units with new duct work to fix the balance issues that we were having in our 3200 sq ft home. Now, the temperature in our home is consistent in the various rooms which has been a problem over the past 20 years. Keith said that the project was underbid by error but they stuck to the quote that was given to us. We had several men from the company working on the project. By far, Pedro C and Kody M stood out and were top notch paying attention to detail and cleaning up after themselves on a daily basis. It was very hot and they stayed late to make sure that we had air conditioning over the weekend. The bottom line is that they did not cut corners and were neat and professional and most importantly delivered on their promise to give us a system that works well. I have already recommended them to 2 of my friends/family."

"Matt arrived on time & fixed duct leak above furnace & water tubing to drain water reinserted & glued. Also got 2 ceiling filters for me unasked & put new filter in. Very reasonable price for labor & supplies. Previous Dependable Heating & Air company sent 2 people who insisted I replace entire furnace and ducts up to roof vent & wouldn t fix simple duct water leak. Admittedly my furnace is old but still working fine. Will never use Dependable again. Matt didn t pressure me to replace furnace & give me a quick $ amount with no pressure. Nice guy. Matt Kazen was wonderful & will definitely use his company again for heating & air conditioning needs."

"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!"

FAQs for air conditioning projects in Napa, 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.
