"This was for semiannual maintenance under contract. Danny performed an excellent job, he has many years of experience. I have used ARS for the heating/air conditioning maintenance for about 35 years. They replaced the equipment about six years ago. It has not failed since replacement."

"T&J Service installed a beautiful new Trane system at my home in Fairfax on May 14, 2024. They were recommended to me by my neighbor who has been using them for many years. Without a doubt, Diep and Tran are the most highly-skilled HVAC professionals that I have encountered in over 40 years. This was a very large, complex system to install and they got it done in one day. These are some of the hardest working, most dedicated guys that I've ever seen! I absolutely love my new Trane system. They even custom made a beautiful plenum for my air handler --handcrafted out of stainless steel (Diep is also a skilled metal craftsman). 5 STARS"

"We ended up totally replacing our heating and air-conditioning unit and everything we have done in the house has been through ET Lawson and under a warranty plan through them. We wanted the same thing. Nothing against Michael & Son. He seemed very knowable."

"Excellent. Very honest - took the time to test the equipment & answer all our questions. A different company we used said it would cost $ 1300 to repair and tried to sell us a whole new unit for $6,500. Andy from Dean Hart was very honest and repaired the unit the same afternoon for several hundred. Saved us thousands! We will use them again in future."

"Needed to replace a 25+ year old HVAC system in the coldest months of the year, so I contacted Advanced Environment Solutions for a bid. I worked with Tammy at AES to schedule the inspection, follow-up, etc. - a fantastic employee. Courteous, professional, and really knows her stuff when it comes to HVAC. Unfortunately, I live in a condo with a tricky indoor/outdoor HVAC set-up that ended up requiring a fairly specific indoor unit that AES did not offer, so I had to go with another company. Still I felt compelled to leave a review for AES and Tammy to highlight their professionalism and service-oriented approach. WiIll absolutely consider AES for future projects."

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.
