"Always stayed in contact by phone before, during, and after install. They worked until after dark because we had no heat during this unusually cold spell. Salesman Chris stopped by during install."

"The installer found that we needed another part, other than just the compressor, that he didn't have (this was for an air-conditioning unit and we live in Arizona so its vital to have this work) so he called around until he found one then drove to pick it up and stayed late to be sure we had a working unit before he left. Also, Clayda is an associate who I dealt with at Mechanical Brothers and she too was amazing! I highly recommend Mechanical Brothers!!"

"Austin went above and beyond expectations, a really thoughtful and caring guy. Had a 20+ y.o. system that keep burning through wires and capacitors. He was extremely insightful and honest and came out on very short notice multiple times until we finally got through all the Home Warrantee back and forth and eventually installed a new split system (gas). I own rental properties and BY FAR this was the best experience with HVAC I've had in my 50 years. You will learn a lot and get fast communication and service. Even helped me apply for a 10 year financing option making the whole process easy and affordable. Thank you, thank you, thank you!!!"

"Exceeded my expectations from the start. Caleb Garver was on time. He efficiently explained what systems would work well in our house. The installers arrived the next day on schedule. Fernando and his co-installer were efficient, worked in horrible heat. The outdoor temperature was 105+. Fernando explained everything and showed us how to use the thermostat and change the filters. Then a senior technician, Robert, came and did a complete inspection and sign off of the job. Because of the outstanding experience with the quote/sale and installation, we were comfortable getting the maintenance plan. We highly recommend Emergency Air."

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.
