"My a/c wasn't blowing cold air the tech, Andrew, showed up and got right to it. He found the problem (the capacitor) and got it replaced in less then 30 minutes. It's working like a charm now. He explained everything as he went along and was top notch professional."

"The service technician was totally professional. He was on time and he called ahead of time to provide an estimated time of arrival. I was especially pleased that he wore protective gear to ensure that guidelines for Covid 19 were followed. This company was a third opinion for my repair. The cost was much less than I received from the previous company. Go with this company if you have heat and air problems."

"Mr. Le was exceptionally good in responding to my call and came within 30min of calling him and installed a brand new heat pump / air conditioner the very next day. The pricing was reasonable and his work was immaculate. He is a very thorough professional and very nice to work with. He is very detail oriented and expects everybody to adhere to his standards and doesn't cut comers. His people were very good and cleaned up my whole work place and left with no trace of any dirt. Highly recommend them."

"⭐️⭐️⭐️⭐️⭐️ I want to start by highlighting the *above and beyond* service I received from Keep Smiling Heating & Air. In the midst of a brutal Atlanta heatwave, I called in a panic because my newer AC unit had suddenly stopped blowing cold air. From the first point of contact, the experience was incredibly professional and reassuring. I received a confirmation text, a follow-up call when the technician was in route, and even a text introduction with a picture and background info on the technician. Who does that? **Keep Smiling does.** Technician **Byron Solares** was exceptional—knowledgeable, professional, and genuinely empathetic. I explained that I have my elderly father with a breathing condition living with me, and Byron not only resolved the issue efficiently, but took the time to explain everything clearly. Thanks to his quick work, we’re resting comfortably tonight."



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.
