They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"In the midst of this summer's hot spell my 18 year old air conditioner died.  I called several companies looking to obtain estimates, one of them being TJ Miller. Although I eventually selected another company to install the air conditioner I was very  impressed with the time and energy provided by Tim Miller in making the estimate. I felt it warranted positive recognition on Angie's List.

Mr. Miller did an initial inspection of the equipment, including entering the crawl space to look at the furnace. He then spent considerable time reviewing my options for replacement equipment as well as explaining how the new air conditioners and furnances worked.

His quote was delivered within 24 hours and was very competitive to the company I ended up selecting (only $100 difference). 
I chose the other company because they had previously done some work for me and they offered a $150 Angie's List coupon. 

Obvioulsy, I cannot speak to how well the company actually performs their work.  However, based on the way I was treated, I would suggest that other members at least consider calling the company when they are looking to replace their heating/cooling systems."

"Work involved air sealing, bath vent duct installation, installation of baffles, and adding blown insulation in attic; great to work with on scheduling; work crews arrived on time, were very thorough and professional, completed the work in less time than estimated, and cleaned my house thoroughly before leaving. Oh, and the price was great, too!"

"We just had Corey install our new Ecobee4 thermostat. He is quite possibly the nicest and most professional technician we have ever had in our home. He was meticulous and courteous. We will definitely call this company again, if we ever have any heating or cooling issues. 5 stars!!!"

FAQs for air conditioning projects in Wilmington, 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.
