"Dad's immediately found the problem. Then they checked AC to make sure everything was operating correcting. Both technicians were courteous, professional and honest with me. This is the second time they have been to our house. I highly recommend them."

"Billy the sales guy is very thorough in his explanation and truly helped us understand what the differences are between systems and how it would benefit our family. He did not come across as pushy or high pressure which helped us feel more comfortable since this is a big purchase for us. We ended up purchasing the AC as planned but replaced the furnace at the same time. Billy was able to give me more information on my current units than I had when purchasing my home! I liked how tech savvy they are as well. Billy communicated through phone but also in text which is much easier for me to do during the workday. And the owner followed up with an email which I loved. I didn't get to be onsite for the install (my husband was) but it was all done in one day. One tech installed the furnace while the other installed the AC. The only thing I worried about was that they guys pushed through all day without a break and that concerned me about whether the job was rushed. But I have to give them credit- everything looks nice and works great ! I would recommend to all my friends and family."

"James was fantastic! He was polite and knowledgeable. He efficiently fixed our air conditioning, and informed us of all the different options we had. We will certainly use this company again if James is any indication of the caliber of staff they employ."

"My AC was out, it was 90 degrees in my house on a Sunday, and Max-Pro worked to squeeze me into their schedule on the very same day! Sean was extremely professional, and took the time to explain exactly what was wrong with my system and why it was causing it to fail. Their rates were also quite reasonable, especially given that he came to my house after hours on a Sunday! I will definitely be using their services again. Highly recommended."

FAQs for air conditioning projects in Pleasant Hill, 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.
