"We ended up totally replacing our heating and air-conditioning unit and everything we have done in the house has been through ET Lawson and under a warranty plan through them. We wanted the same thing. Nothing against Michael & Son. He seemed very knowable."

"I was selling my house and the inspector found the fan was venting into the attic. I needed to have a professional vent it to the outside.. The HVAC tech was on time, diagnosed the problem immediately and had it vented to the outside soffit in a less than half an hour. it looks good, not noticeable and now I meet code. I thought the price was a bit high. I have a one story ranch and all he had to do was cut a hole in the soffit, reach in and pull down the vent. Other than that he did a wonderful job and I am happy.

"Our air conditioning system was not working properly. We called the company that put the system in and their technician told us we needed to install a new condenser. We called Parrish for an estimate on a new condenser based on Home Advisor's recommendation. Parrish Services came to our home, performed a diagnosis, and determined we did not need a new condenser. Ended up saving us thousands!"

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.
