"I am writing to express my deep disappointment with the service provided by McGinley & Sons. Despite multiple attempts to resolve this issue, I have yet to receive the promised refund for work that was never completed. As a cancer survivor undergoing surveillance scans, the refund would greatly assist in covering my medical expenses. The lack of response and follow-through has added unnecessary stress during an already difficult time. In addition to this, I had to hire a lawyer to recover my down payment, which cost me additional money. Moreover, he did not offer to compensate me for the extra expenses, including hiring an electrician to install a wire for the heat pump he could not install. Despite repeated attempts to have the deposit returned, I finally received it after engaging legal assistance. I hope this review will encourage McGinley & Sons to address this matter promptly and fairly."

"Very professional. But could have cleaned up after themselves a little better in the attic. I had a small issue and they got back to me right away and took care of it. I would highly recommend McGinley and Sons heating and Air Conditioning to anyone looking to install central air."

"They replaced our hot water tank. Nice neat job, fair price and excellent customer service."
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.
