"I could not be more pleased with the service I received from Friends Heating and Air! They added me in same day even though that meant not arriving until about 7pm and didn't leave until the job was done close to 10pm. Emre was very pleasant, professional and knowledgeable. Earlier that day, Fuse Services tried to sell me a $15,000 new AC unit due to the "mold" being so bad that I would also need to replace all the duct work. Emre told me the "mold" was actually just years of accumulated dirt and dust and all I needed was to change out the fan motor and do a clean-up of the inside of the unit and he didn't even recommend cleaning the duct work since he didn't feel it was needed. Cost was $500. I don't see how these other people sleep at night. Anyway, these guys are very honest and just good folks. I HIGHLY recommend Friends Heating and Air!!"

"Wes has done several units for us and has serviced our rentals when needed. Great to work with. Excellent and fast service. Very reasonable pricing. Extremely knowledgeable. Everything you need for heart and air."
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.
