"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 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!"

"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"The technician came out after 11 pm when other companies could not until the next morning. Mr. Meriweather, was very courteous, and fast with the repair. I will definitely call G & R in the future for any heating and air conditioning needs."

"I have lived in my home for over 23 years and have used several different Heating and Air companies thru the years... I needed service in Sept 2018 and had various coupon prices of $39 and $49 for an A/C tune up and was about to chose on of them but decided to check Angie's list for a review or google for the coupon companies. That is when I found American Family HVAC and started to read their reviews.. For some reason, I decided to use this company even tho the cost was a bit more money and boy am I ever happy that I went with my hunch. Sometimes it is NOT always about the money. I was really looking for an A/C furnace company that I could count on and use regularly. Not only was the repair gentleman that came out, on time and very thorough and professional but he spent a long time and I feel that I received the most thorough tune up that I have ever had. Josh, the service tech was just a delight and the best part was that this company has a membership contract that I was able to purchase. It is a small monthly charge monthly and . I get 2 free tune-ups a year included in the monthly fee for NO charge and if I need any service work I get 20% off of the charge and same day service...all for only $12.95 a month. What a wonderful idea and I cannot express how happy I am with this choice. It is a win-win deal for me and the company. I am a very happy camper with my choice of this company."

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.
