"Called for a tech to do a service check on a system in our home we purchased last year. The came out on a Tuesday. He did a check and stated our AC system was nearly empty of freon. Our unit is 17 yrs old so we opted for a complete new hvac as most other items were new to the home. Friday, same week George came back and did a great job removing and installing our new hvac. Pricing was fair and the service was great. Hoping for many yrs of use. Timing and service were 5 stars. I would not hesitate to recommend Honest Abes co to anyone needing service. Install - 6/25/21 Cheers Steve..."

"Tuesday, February 7, 2023, CW (Charles Waterman) of Commercial Home Services In Camdenton Missouri, installed a new thermostat for the furnace in my house in Eldon Missouri. After he had left the thermostat wasnâ t working correctly, so I called him the next day to see if he could return and take a look at it. Over the next few days I contacted him several times. Apparently he had a very busy week, but first thing Monday morning February 13, 2023 he called me back and said that he would go by the house that morning and take a look at the thermostat. He found the thermostat was working but the furnace had several problems which he informed me would be fairly expensive to repair. I have decided to replace the furnace which is over 30 years old with a heat pump. Charles has been courteous and very helpful. I appreciate what heâ s done for us and would recommend him."

"As a new home owner, I am more the thrilled by the high quality of work done by Indian Summer Pool and Spa. I called Doug Fender (one of the owners), who made an immediate appointment with me to discus my plans to expand my patio, along with three other companies. Doug when through all available options, costs and expectations on the job I wanted done. Not only did he have a great team of employee's show up on time, they had everything organized from ground prep, rock deliver, concrete delivery, and temporary fencing down to the minute. I was very impressed with the owners showing up to make sure that I as a home owner was happy with each step of the process and that every employee was very efficient and knew their area of expertise. I would highly recommend them to anyone needing work done on a project you want done right. Just a note not only did the come in on budget, but the other companies I called did not have any where the game plans or explain the details of what to expect. This is a company you will be happy with."

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.
