"Our air conditioning stopped working on a very hot day and I called Andrew Mengis who was working at another job. He said he would come after he finished his current job. After calling me twice to let me know he was delayed, he arrived at our house at 8:15 pm. He quickly diagnosed the problem as a faulty pump and made a temporary fix. As promised, Andrew came the following morning with a new pump which he installed and then completed a more thorough maintenance check of our heating and air conditioning systems as we requested since it hadn't been done in several years. We were very impressed by Andrew's responsiveness, professionalism, and efficiency. We highly recommend Mengis Heating and Cooling!"

"We did not think it was even possible for our old house to have central air. After a consultation we were pleasantly surprised that our 3 story home with no duct work had a full install of central air. No more window units!! The install happened shortly after the consult and was done in a very timely manner . He was informative from day one explaining all the work that was involved . I could not be happier with this investment to Our home and found that his pricing was very reasonable."

"Fantastic! Ken was our second estimate, and WHAT a difference. We knew there was a leak in the system that was on 3 1/2 years old, but the previous company wanted more than triple the cost of three pounds of refrigerant. Further cost was a $300 diagnostic test to locate the leak and at least $500 to repair it. Ken made the same diagnosis, charged $30/lb for the 3 lbs needed to recharge the system and $175 to put in a leak stop chemical to stop the leak. The difference between $350 and $1000 was VERY welcome. Highly recommend Ken and Youngstown Comfort Systems. He's rebuilding his father's business and we will call him back for future work."

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.
