"When my air conditioning stopped working, I first contacted a different HVAC company and the technician made the assessment that the compressor was shot and in need of replacement. They recommended the option of going with a completely new AC unit. I decided to get a second opinion from Shavitz (having seen their sticker on some of the AC units in my building). Cornelius from Shavitz confirmed the initial diagnosis and the estimates that the project manager, Lou, subsequently quoted me were very much in line with what I received from the other company. About $200 more for a comparable AC model, but given what I read about the level of quality Shavitz brings, I decided to go forward with using Shavitz to perform the replacement of my air conditioner. Scheduling the appointment with Chris was a breeze. The day the work was scheduled to be performed, the installation team, Mike D and Mario, arrived exactly on time and quickly got to work. They were professional, friendly, and very knowledgeable about what they were doing. I especially appreciated how thorough they were in the installation and testing of the system. The AC units are on the rooftop of the condo building so there is a long distance between the AC unit and the furnace/AC coil in my condo. Because of this, it took a bit of time to flush the lines, fill with the refrigerant, and test it to make sure it was working as expected. Being a hot day and a Friday, it would have been easy for them to test it to a point where it was “good enough”. Due to the thoroughness of their testing they found an issue in the lines that they were able to fix. While this added time to an already long day, they explained to me what they were doing and the importance of it. All in all, I was very impressed with Mike and Mario’s level of skill and pride they have in their craft. I will absolutely be using Shavitz exclusively going forward for my air conditioning and heating work, and highly recommend them."

"We are beyond happy with the work and professionalism of Porterhouse Cooling and Heating. I called for an estimate and they were out the next day. Then that same day they were able to get us set up for our work. They began the project only a day later. They truly were amazing to work with and supported us throughout the process. We needed a huge job done, because we switched from all electrical to adding gas to our house along with a furnace, water heater, air conditioner, and all new ductwork. We had multiple obstacles that most people did not want to take on. Porterhouse helped us come up with solutions and were very reasonable. They were extremely hard working and did a great job with our house. We love our new heating and air systems! We also have a new thermostat that is wonderful. I highly recommend them for any heating or cooling needs!"

"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!"

"The company called to advise that the technician was on the way about 20 minutes prior to his scheduled arrival.  The technician was at our house at 12 PM for a visit scheduled to be between 12 PM and 2 PM.  He was very thorough in checking our air conditioning equipment inside and out.  He did a very good job of explaining what he had done and that everything was in good condition.  He was in and out in less than a half hour.

"He was very good.  I had some company coming from out of town and my air conditioning wasn't working.  He came that day to fix it.  He knows what he is doing.  He gets the job done.  He came within 1/2 hour of my phone call because he was in the area.  He got my air conditioner going right away.  It was really hot that day.  He took care of it right away.  He could have tried to tell me it was the compressor or something, but he didn't.  He was prompt, he did a good job, and he was fair.  He installed a furnace and air conditioner at my mother's house as well.  He did a good job there too.  He was here previously to try and quiet down my air conditioning, but nothing seemed to work too well.  He was really good on the installation, but I thought he was a little high on the repair. "

"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.
