"Our air conditioning was not working and our house was extremely hot. I called on a Sunday afternoon and Matt came later in the afternoon and fixed our problem. Our air-conditioning is working again and we will finally be able to have a good night sleep. I was thrilled that Matt came out on a Sunday evening and fixed our problem. He also took the time to show me how to change the filters in our unit and had me practice to make sure that I could do it by myself. I would highly recommend Conde Tech Services."

"I was very impressed by Polar Bear Heating & Air Conditioning. They were professional, courteous, sensitive to time and financial constraints, and really wonderful to work with. Joe took a lot of time discussing options with me and ultimately even came to my house to see the system and discuss next steps in person. Angel's knowledge of HVAC systems and repair was outstanding. I really appreciated all of the time and effort they put into fixing our problem. I would HIGHLY recommend them and will absolutely use them again if we have any additional HVAC issues.

"I am very happy to have selected SwiftPro to install a heat pump in my home. The price for the Trane system was significantly below what the competitors were offering, and every aspect of the installation process went very smoothly. When I had some trouble with the control panel after the installers had left, the owner, Tyler, got the technician immediately on the phone to correct my mistake. The added bonus is that the air quality of my home has clearly improved by reducing dramatically the use of my natural-gas burning furnace. So, I’m happy to attest that SwiftPro really is as professional as Tyler claims in his initial sales presentation."

"We have been using Virginia Air for several years now to service our Heating and A/C systems. Chris and Billy do an outstanding and thorough job, very knowledgeable and have always been very reasonably priced. We trusted them to upgrade / replace our systems last year and couldn't be happier with the results! Would highly recommend Virginia Air!!"

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.
