"I cannot say how pleased I am on choosing Advanced Heating and Air Conditioning to replace my A/C. The tech who did the work was incredibly professional, and in my opinion, was an expert in the HVAC field. Not only did they replace my A/C with a great product that fits my needs (no upselling, etc) they went the extra mile to ensure that the duct work was repairs, more safety guards were implemented, and he even connected a new humidifier to my Nest device (something I had no connection to previously)! Best of all, the price was very competitive! A certain 'large appliance store' chain wanted more than DOUBLE what I paid. I paid what was in line with the average costs as recommended by Home Advisor."

"The technician was very professional and was able to answer many of my questions about the condition of my HVAC system that I inherited and its probable lifetime. I sensed that he was being honest and straightforward. Rather than accept his extensive list of possible replacement parts, I opted to have him install the one that he believed to be the most urgent- the capacitor. So far the unit seems to be functioning well."

"They did an exceptional job replacing my manufactured home furnace/central AC/thermostat despite encountering some problems removing the 30 year old system. And they got it all done in a day!"
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.
