"The company convinced us to sign an annual agreement in December 2015 when they performed a "coupon" periodic inspection on the gas furnace. By late May they had not called to perform a periodic inspection on the central split-system air conditioner. Noticed system was running longer than usual and not removing humidity very well. Called to schedule the periodic inspection and advised them system had iced up earlier that week. Technician found refrigerant pressure was low and added 4 pounds R-22 at $110 per pound - system held 6.5 pounds total. He stated he could also add a sealer if I wanted - of course I wanted! Stated the sealer would surely take care of any leaks - additional $95. Ten days later system was not cooling well or removing humidity. Called another company referred to by a friend. That tech looked for a leak in the evaporator coil by spraying with soapy water. With none found he followed the liquid line toward the condenser unit and found the line was discolored in two places where it was laying directly on the ground - furnace and coil are in crawl space - and took photos to show me. Found the leak was in the liquid line. He stated he was not supposed to add R-22 refrigerant to a system with known leaks - for environmental reasons - and we asked for quotes to replace the liquid line and evaporator coil since it was 16 years old and quite corroded - I had also read that particular coil had historically suffered from corrosion issues. As the repair came out at 40 percent of the cost of a new system we went with a new system with a SEER rating 4 points higher than the existing system. I ended up very disappointed that the first company, 1) had not scheduled a periodic check of the air conditioner by June 1; 2) charged more than twice the per pound price for R-22 refrigerant than the second company quoted, and 3) never bothered to look for a known leak in the system. I must add that the technician was very nice and answered a ton of my questions but I believe he put too much confidence in the sealer and should have looked for the known leak before doing anything else."

"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."

"I cannot speak highly enough about this company. My a/c went out during one of the hottest weeks of the summer - 98 and 99 degree days. I called several companies and no one could do the work right away - I got estimates between 3 days to 2 weeks. I explained to each company that I had 3, 17 year old, long-hair kitties that were suffering with the heat. Midlothian Mechanical sent a rep out within hours. He took the time to explain the difference between the units he recommended so that I could make a good decision on which unit to purchase. He charged the broken unit with Freon two times at no charge. He must def be an animal lover because he said he had a job the next day that could be rearranged and they could install the units the next day. He bent over backwards for me (and my old senior kitties) and I very much appreciate it. The heat pump and air handler were installed professionally and quickly, without incident. I LOVE my new YORK heat pump - it even looks good! BTW, the "he" I am speaking of is Kevin (one of the owners). I didn't even know I was speaking to the owner until we were well into the conversation. Very nice person, great company and excellent YORK product. I am very very pleased and I highly recommend Midlothian Mechanical and they're yearly maintenance plan."

FAQs for air conditioning projects in Chester, VA

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.
