"Took three times to get it fixed completely. The first repairman had to replace a part and we thought that was all that was needed. The next day or so, water was on the floor again so I contacted Air Serve again. The next problem was a crack in a pan. One of the repairmen, Cliff, was able to keep water from continually dripping on the floor while we had to wait for a new part to come in. It worked quite well. When the part did come in, he did a lot of work to get the new part in. I would have to rate him excellent. The air conditioner is now working fine. Couldnt put an accurate price, because we pay American Home Shield every month and had to pay $75 for the first trip, $86 for the second and I believe $100 for the last trip. Some was not covered by American Home Shield."

"Samuel is amazing. I hired Samuel to replace a closet door in the apartment I just moved out of. I could not find the door I needed, and Samuel went out of his way to find the door, and pick it up. He arrived on time, was very professional, personable and kind. It was refreshing to work with Samuel because he treated me with respect, his fees are fair, and he didn’t try to price gauge the project because I’m a woman, like some contractors I considered hiring for projects I want completed in my new home. I look forward to working with Samuel to complete the other projects I want/need completed. I will absolutely refer Samuel to my family and friends who want/need to hire a contractor."

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

FAQs for air conditioning projects in Rolla, MO

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.
