"I had my HVAC replaced in my condo during the summer of 2018. I had just moved and had painters working when it malfunctioned. There turned out to be a leak and I decided to purchase a new system after hearing about previous problems with the unit. I had used Valairco for annual checkups and was happy with the company. I ordered the new system requesting it be done as soon as possible because of the situation. They immediately ordered the new system and installed it as soon as it was shipped to them. Lou did a great job and I’m happy with my purchase and guarantee."

"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 first contract (Air Conditioning) went very well and completed on time. The second (Masonry) was delayed and took a while to complete. The workmanship was OK anyways."

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.
