"Thank you ZACK for your professionalism taking pictures of the work you did cleaning the filters of my A/C system outside. This is the first time anyone showed me pictures of the work they did. You were kind and explained to me when was the best time to have my heating system checked and when to call to make an appt. for the fall. You were knowledgeable, caring, and I felt safe with you. What a GREAT employee to represent Palmer Gas. Also, Thank you Customer Service Rep. MICHELLE L. - you answered all questions asked of you in a friendly and professional way. That is why I stay with Palmer Gas. Heidi Ricci"

"Kevin was great. Our Central Air System died during a Heat Wave . When other companies told us they couldnâ t give us an appointment for two weeks, Kevin came the next morning and on a Holiday weekend. He was quick and reasonably priced. We would highly recommend Kevin Russo to anyone looking."

"Patrick called Friday night and showed up at 7:15 AM on a Saturday morning (OMG) to repair a central A/C system that was icing up inside. I'm still waiting to hear from the other 2 companies that were listed in my area. I know they will call Monday which would mean myself and my disabled wife would spend a very uncomfortable weekend and probably longer because most HVAC companies don't work weekends and it usually takes at least a day to schedule an appointment. Not fun when the humidity is 65% and the temp is close to 80. Patrick did a great job, A/C is running like new. Will hire him again and recommend him in a heart beat. Prices are very reasonable. Hire him!"

"I had Arete Electric provide an interior and exterior upgrade and couldn’t have been more pleased with the service and quality of their work. I highly recommend them to anyone looking for a job done right."
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.
