"I was looking for someone to put a very large window air conditioner in as soon as possible. I have medical reasons and have to use it 24/7. I had called several companies but, understandably they were all booked weeks out. When Jason and I met over the phone he was already booked for the day but said he would come over after he had completed that job. He is such a nice guy and I loved how he got to work. Mostly, I admired the work he did, very neat and the caulking was awesome. The reason I say this is because I have had 3 air conditioners put in over a 16 year period and each of them were done sloppy. Jason does many different jobs besides installing air conditioners and I can imagine he takes great pride in all he does. Give Jason a call I am sure you wont be disappointed"

"Mana Mechanical’s owner, David, is a responsible professional who takes his commitments seriously. I needed to replace our old rooftop AC duct urgently. David was the only one who committed to meeting our aggressive schedule. He was honest with me that this would be his new company’s first job. I was a bit anxious, but decided to take a chance because I was impressed by his diligence during his on-site inspection. David acted as the general contractor, hiring engineers, electrician, crane operators, etc. His operation was flawless despite several unforeseen challenges, which he spent extra time and energy resolving himself. He even took extra work not included in original agreement staying late to finish them after his team had gone home. Even after the job was finished and paid for, he provided a detailed report with recommendations for other concerns he noticed on our rooftop. I am so grateful to have met David and highly recommend Mana Mechanical for your next project."

"Everyone from the owner down was professional friendly and reliable. I would highly recommend this company to anyone who is looking to fix their split air conditioner."
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.
