"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."

"Steven Cooper was willing to take on a small job and came through was a thorough professional. He went the extra mile after servicing our two units and fixed the sealing my husband had done so the units are now air tight. He knew what he was doing, did it well and quickly and gave value for the fee he charged. We'll have him come next year."

"Chris was great. He gave an estimated arrival time and kept me posted about when he would arrive. Once he arrived, he was very professional and respectful of my home; he didn't even mind my nosy cat. He gave me an assessment of possible repairs needed on my portable AC, gave me an estimate for possible costs and provided an invoice on the spot. He made the whole process very easy, and I appreciate the time he took to explain everything. I would definitely hire DG HVAC & Home Services again for my appliance repair."
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.
