"My HVAC went out right before the cold snap and it was really cold in the house. I had called another company and they were thousands more so I took a chance and called Arnold’s and it’s the smartest thing I have ever done! The unit is excellent and will save me money on utility costs. He was there Monday morning and had me up and running in no time! He knows what he’s doing and didn’t tack on a service fee and other additional costs. I’m so glad that I found him and I highly recommend him for your HVAC needs. You won’t regret it! Thanks Arnold’s"

"Jake, the owner, was going to be in the area and offered to stop by and take a look at the cooling unit and see what the problem was. He discover and issue with the control board being in suspend mode and cleared the issue. Tested the unit to verify it was operating normally. Great job, this was a Sunday and was not expecting service until Monday. Not many service providers would do that and not charge quite a bit of a premium."

"Dennis was prompt, clean, and responsive to all questions. He completed the original work (venting 4 exhaust fans outside) within the budget shared during the timeframe he provided. We have since used him for other tasks including fixing our fence and building a gate for our fence. He also color matached the pain. We will use Dennis again."

FAQs for air conditioning projects in Shelbyville, TN

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.
