"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"Adam and John Came in and diagnosed the root cause of the water leak I was experiencing. They provided several options to mitigate the issue, ranging from a quick fix to a more in-depth, long-term solution, drastically reducing the likelihood of the problem. They went above and beyond to fix my water leak, and I will be using Hunt Plumbing, Heating, and Air Conditioning, LLC for all future plumbing needs."

"It was pricy, but it was good service. Well, that's hard to say because it's all expensive, as oppose to any other air conditioning company, it's about the same, just too much money in general."

"Josh came to provide an appraisal and he quickly understood what needed to be done and provided a solution. Jose came out quickly and widened the opening so we could get our furnace serviced and our heat turned on. Jose returned and within 4 hours had the electrical outlet moved, new framing complete and painted, floor tile replaced, and new doors installed. I am very impressed with the service provided by JW and will contact them again for any needed repairs."

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.
