"The inside component of our air conditioning quit. Shavitz dispatched Bradley S who arrived within the promised time-slot. He found the drain that removed the coil condensation had become blocked. He cleared it but after pouring a lot of water into the tray, decided a more aggressive cleaning was needed. White vinegar and blasts of nitrogen from a portable tank removed the last of the gunk that had accumulated over time. Bradley walked me through what he was doing and answered all my questions. The work was done on warranty because the company had replaced the outside part of the air conditioning a couple of months previously. They could have argued that the warranty only covered the outside machinery but took a more generous view of the coverage."

"Home AC went out when it was 90 degrees outside. BESCO Air came out the next day and Voila! Problem found and fixed. I've used these guys for years for both heating and AC. When other companies don't have the resources to respond promptly, BESCO comes through for me. With them, loyalty still matters."

"Home Comfort Systems replaced my old air conditioner with a new American Standard air conditioner. The day it was going to be installed, one of the owners, Steve, stopped by to look at the old air conditioner, and explain what was going to be done. The installers arrived an hour later, explained to me exactly what they were going to do, and all the specs of the new air conditioner. Roughly 2 hours later, they were finished. They explained the warranty, and cleaned up. The only evidence that they were there was the new air conditioner, no debris left behind. They were very professional, and I would gladly use them again!"

"Our AC unit had stopped working the previous day, so I called a few local companies in the morning.
The only one that answered without going through voicemail was Jon (the owner) at JML.
After explaining our problem he had a few ideas of the cause, so we scheduled a service call for the same day.  He called when he was on his way and arrived on time.
Once here, he checked over the unit and diagnosed the problem.  Fixed everything while he was here and kept the price to the service charge.
Jon also gave some advice on a separate issue with the location and sizing of our return air ducts that would make the system more efficient.

FAQs for air conditioning projects in Des Plaines, IL

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.
