"Rick is a gem: knowledgeable, efficient with a great sense of humor. We had an appointment reminder call the day before and Rick arrived within the 3 hour window. He recommended I have the air con part of the system cleaned and serviced next spring."

"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"Excellent customer experience from beginning to end. Alex was very professional, honest, and not aggressive for my business. Huft provided $4,000 in rebates and a $1,600 promotional credit for an electric HVAC system upgrade! The installers were prompt, expedient, and considerate to not make a mess. The workmanship was great in the interior attic and for the exterior condenser. They cleaned-up afterwards and left no trace or trash. They even ran diagnostic tests after installation and provided the written results with follow-up 6 months later to inspect and make any adjustments. I would highly recommend Huft Heating and Air Conditioning for a new HVAC install."

"I have an old floor furnace that needed to meet PGE standards before gas could be turned back on. He insured that it was and re established gas flow. Hardly anyone would touch it and I was without it for over 2 years. Not only did Matt fix it within an hour, but also restored electrical power in my garage in a separate issue. Highly recommended. Not cheap, but if you want quality, Kazen HVAC is a name you can trust to get it done right in a most expeditious manner."

"B&W responded quickly to my request for shed roof cleaning for insurance purposes. They power washed the roof and sent me photos, which were praised by my insurance representative and forwarded to my insurance company. They also filled an erosion hole next to the shed, and cleaned the roof, gutters, and downspouts of my main house. I would recommend B&W without hesitation."

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.
