"They were absolutely wonderful. They are great people to deal with. It's a husband and wife company and they've just hired two new people. Everybody is well trained. They are very good. I have a gas heater and they even put a humidifier on it. They give you a quote before they do any work. They answer all your questions and explain the contract. I ran into them in a grocery store and they immediately recognized me; they are very personable."

"Dave did a great job, he explained what caused our Heat pump to stop working. We bought this unit last June 2019 . So we were very upset when the unit stopped working, it was so hot and Dave had to go up into our attic / crawl space. That was super hot, but he was able to find the problem and get our unit to work. We are very thankful for having Dave as our technician. Thank you Dave and Rohrer's One Hour Heating and Air Conditioning. We have been with them for 35 years."

"The engineers overrided the recommendation of the salesman and initially installed a furnace Is with a much higher BTU rating than my small place required resulting in excessively dry air which for me, was a health risk. After I complained they somewhat reluctantly replaced it with an appropriate furnace. The sales representative did strive to do what it took to satisfy me which I Greatly appreciate. And the technicians and installers were and installers were very good."

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.
