"Rearranged his schedule to squeeze me in. Cleaned the a/c and found I was running way too low on refrigerant. Filled the line with a sealant to stop any small leak I may have had and topped off the system. House is an icebox once again. Friendly. Great attitude. Knew what he was doing. Would call again."

"Last April I purchased a brand new condominium. There was quite a bit of construction dust as well as some construction debris in the air ducts once the building was completed. I finally decided to hire Dustbusters Duct Cleaning this month to clean them out. The dryer vent was also cleaned and the central AC coil was inspected. Jeremy was the technician who performed the job. He was punctual, polite and courteous, and very knowledgeable. Jeremy explained the entire process to me and showed me before and after pictures of the air ducts. I have noticed that the air flow from my heating system seems stronger now which indicates to me that cleaning the air ducts has improved the efficiency of my heating system. I would definitely hire this company again. Cheryl B."
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.
