"This company went above and beyond. From the estimate to the install of both a new furnace and air conditioning unit quickly after the estimate. We had been without heat for 4 days in December in Michigan. Glad to sleep in a home with heat again."

"We turned our A/C on for the first time this year and it didn’t work. I called a local company and I was charged 192.00 to get it fixed, so I thought. It wasn’t , after two weeks it stopped working. I found Edwards Mechanical on Angie’s list and requested an estimate. I received a call within a couple hours and set up an appointment. Zack came out and really knew what he was doing. He found the leaks and repaired them and cleaned the unit. The other company technician said he couldn’t find a leak. Now I can relax and not worry about my A/C not working as it is fixed correctly. And the work backed up by Edwards guarantee. I will definitely hire Edwards again."

"Andrew and Frank did an awesome job putting together my gazebo. They were quick, friendly, and talented. The gazebo looks fantastic."
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.
