"We decided to use Shavitz Heating & Air Conditioning as the company for the install of our new furnace. What impressed us about Shavitz was their employees. They made the entire process a positive experience. Everyone that interacted with us had a friendly and professional demeanor. It started with the sales visit by Will Gutierrez who was a pleasure to deal with. He provided us with several options while never pressuring us to lean one way or another. He was patient with us and answered all our questions. His courteous approach gave us a positive view of the company he represented. The installing technician, Linas, and the tech that was assisting him only continued this professional trend. They both were equally as courteous. Once the work was complete, Linas made sure he answered all of our questions and that we felt comfortable with the operation of our new furnace and humidifier before he left. His patience was very much appreciated. He also made sure the area were the work was done was clean and all trash removed. Will Gutierrez followed up with us a few days afterwards to make sure all was well, and that we were pleased with the work and our new purchase. Our answer was a definite, yes."

"I got 4 separate quotes and Home Comfort Systems was below all of them. Steve recommended that we go with a smaller sized air conditioner unit. I was skeptical, but it was the correct decision. Our home is much more comfortable due to the lower humidity levels. The installation crew was courteous and showed up right on time. After the install was completed we noticed some noise coming from the condensation line. I called Steve and the next day his service crew arrived to add a small vent to the line and problem was solved. I was impressed how quickly they responded to my concerns. I would recommend them to anyone considering replacing or repairing an air conditioner unit or furnace. Great pricing, responsive, and excellent service."

"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

"We called United Heating and Air Conditioning for an annual furnace inspection for our new home. They scheduled quickly and easily. We then had a conflict and they re-scheduled just as easily. When they inspected the furnace it turned out it was extremely old and no longer safely operable. We required an emergency replacement. This was in November and we didn't want to be without a furnace. United Heating and Air Conditioning was able to come the next day (!) and install a new furnace. They took care of the installation, confirmed it worked, and hauled away our old furnace. They were quick and professional and stuck exactly to the quote. We were extremely satisfied and will definitely be reaching out to them when it's time to check (and possibly replace!) our air conditioning unit. Highly recommend!"

FAQs for air conditioning projects in Glen Ellyn, 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.
