"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."

"We purchased a new central air conditioner and a 2-stage furnace. In addition, they needed to update the air circulation to and from the system, which was nicely done. Needed a little tweaking, and one of the owners came out to perform the simple task himself."

"The technician arrived on time, explained what he would do and how he would do it and was quite professional.  He even showed me what the vents sytem looked like, before and after cleaning - not just on one of the lines, but on any one I chose to see & I chose a lot.  They were very respectful of our home, which was very important to me because we just had it painted and replaced all the carpetting.   They even had protection devices that they put near the corners of our walls so that their air hose would not damage the paint or wood trim.  It took 2 guys about 3 hours to do our entire house, which is less than 2,000 sq feet.  The technician also pointed out a problem with our duct-work in our crawl space that is costing me $$$ and I intend to have repaired.

"Another contractor contacted me and was able to come out right away and fix my issue. However I would definitely consider Affordable Air as they were very professional and also contacted me rather quickly just not before the other contractor did."

FAQs for air conditioning projects in Naperville, 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.
