"The work was overpriced, poorly done, faulty, and the list goes on! My High Priced electronic air filter failed in less than 5 years, the condensation pump has apparently had a leak for 5 years that I did not notice, until the damage had taken it's toll. I called for the "free" 1 year service (twice) and 1 time was scheduled and no one ever came, and then a re-call on it and no one ever came, left a note or called on either."
Logan A/C & Heat Services offered value, competitive pricing, top of the line Trane equipment, nice financing options that other companies did not offer. Dan was my sales rep that offered the above services. Bobby was the installer & was professional & did a great job. Install was scheduled on a Monday after I committed on a Friday; so very quick! Trane 20XV & Trane XC95m.

FAQs for air conditioning projects in Williamsburg, OH

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.
