"On July 6, 2018, when it was sizzling hot at 107 degree, my air conditioning system had water leaking suddenly. I was panicked and called all the numbers that I had of this company. It was 8:00 pm and I thought they were closed already. But in half an hour, Jake called me back to tell me he would send over somebody to solve my problem. At 10:30 Antonio and John showed up. When they finished the job at midnight, they were sweating all over. The following day Jake arranged Steve to double check. All of them were very nice. I greatly appreciate their care and hard-working. It is worthwhile to do business with them because they will still take care of the customers even after the project is completed."

"We contacted MSP for air conditioning services. Their coustomer ratings on Yelp were great. MSP was able to come out right away. The team from Angel Perez, technician, to the installers, Don and Don and those that work in the office were nothing less than helpful, kind, professional, informative and courteous. The installation process was flawless and took just a few hours. The guys were very friendly but more importantly, they made us feel confident in what they were doing. We worked out the finances which was a very simple and easy process and by the end of the day we had nice cool air flowing on a day that had temperatures in the high 90s. We are very thankful and grateful to MSP Heating and Air Conditioning. I feel certain you would be too."

My husband hired them to install a new air conditioning unit over a year ago and we called them for the yearly routine cleaning now. Their prices are competitive. They are honest. We highly recommend them."

"We recently had our air conditioning system replaced by SERVLegacy and the whole experience was excellent from start to finish. The team was professional, respectful, and took the time to explain everything clearly without trying to pressure us into anything. The installation went smoothly, they arrived on time, kept the work area clean, and made sure everything was running properly before leaving. You can tell they really care about the quality of their work and customer service. The new system has been working great and the house feels much more comfortable already. It’s hard to find companies that are reliable and honest nowadays, but SERVLegacy definitely exceeded our expectations. Highly recommend them to anyone looking for AC replacement or HVAC work."

"My central air conditioning system had problems, Doug Brewer from Northstar found the problem right away, explained everything in detail and gave me options to save money. I will definitely be using him and Northstar if I cannot solve the problem by myself. Highly recommend."

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.
