Mustang Home Services was founded on a lifetime of service, hard work, and earning trust the right way.\nAfter 27 years in the United States Navy, our founder retired as a Chief Warrant Officer, having worked his way up from the most junior enlisted rank. That journey shaped everything Mustang Home Services stands for—discipline, accountability, and respect for the people you serve. Nothing was handed over; every milestone was earned through consistency, leadership, and getting the job done right.\nThe name Mustang is a nod to that path. In the Navy, a Mustang is someone who rises through the enlisted ranks and earns a commission—someone who understands the work at every level and leads by example. That same mindset drives how we serve our customers today: hands‑on, knowledgeable, and committed to excellence without shortcuts.\nAfter spending most of a military career moving from duty station to duty station, we made the decision to finally put down roots and call Virginia Beach home.

"Of the three companies that I contacted, this was after normal hours, blistering cold was the only one to call me that same evening. I was impressed on the phone and we made an appointment for the next morning. He showed up on time, was neat in appearance and very friendly and knowledgeable. Gave me a price and stuck to it even though he encountered an unexpected difficulty during the job. Outstanding service. I will definitely use them again. Of the other two companies, one did contact me the next day, and the other one the day after that."

"Prompt. Excellent quality of work. He's on my list if Ii ever need air conditioning or heat pump work again."
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.
