"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!"

"Chris was extremely professional and very skilled at his trade. He completed the work within 2 days of our first contact and kept excellent communication about costs, time of arrival for first consultation and date of service. The projects were challenging and he did incredible carpentry. He was very good at keeping the area clean and respectful of my home. We have already discussed additional work that he will do on the house. I am excited to work with him again and recommend him without reservation. He is a breath of fresh air for someone to really work with a homeowner!"

"Due to an electrical storm last year, We've been without central air since Oct. 2016. And no one could replace our old propeller that got hit by lightning but "Grainger." Dale was Prompt & Polite. Dale is delightful, honest, fair, & knows what he's doing and obviously loves what he does. He was very nice, understanding and patient with my questions & he took his time explaining several details with great answers! Very reasonable pricing for all the work he done. He'll be our go to Central Air Repair Man if ever we need him. However, he did introduce a lot of DIYs for us to try first in case of emergencies. I simply can't say enough good about Dale. He's the absolute BEST!"

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.
