"The Appliance Guy (Justin) was exactly what we needed. Straight shooting, to the point, knowledgeable and professional. Repaired our 1930s antique Magic Chef that others quoted us insane amounts to get up and running. Justin came in, did a thorough cleaning, located the issue, repaired the pilot light system and got her up and running at a fair price. So pleased with the outcome of his work. Will 100% use again for future appliance needs."

"I wish there were a rating higher than 5...that's how good they were. Alex S. & Dimitri were professional, courteous, timely and explained every step. I used them to clean out the dryer vent, but will also be hiring this company to clean out the air conditioning vents as well."

"We had our old boiler removed and a new 250,000 BTU Weil-McLain installed. The experience was great. The price was really fair, especially for the quality of work. They showed up right on time, got straight to work, and you could tell they knew exactly what they were doing. Everything was done in a very organized and professional way, but still felt easy and stress-free on our end. What I appreciated most was how clean and quick they were—no mess left behind, and the job was done faster than expected without rushing anything. Overall, just solid, reliable service. Would definitely recommend them to anyone needing boiler work."

Welcome to Shepherd Eng Heating Cooling Refrigeration Appliance Repair Service & Installation, your trusted partner for all your HVAC needs. This company was created in 2015. It was created with the idea that HVAC-R will one day help to change how people live, work and interact with the closed system of a house or business. With a legacy of excellence and a commitment to unparalleled service, we are your go-to experts in creating comfortable, efficient, and reliable indoor environments.
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.
