"The repair on my water heater was completed to satisfaction on the second call.  There was confusion on the charges for the first and second call however the owner and president of the company discussed with me and agreed with me on what the charges should have been.  He even went one step further reducing the cost of the service call to only what was charged for the initial assessment.  I can say with complete confidence that the owner of the company is very fair and wants complete satisfaction with his customers.  Anyone considering using TMI for Plumbing/Heating/Air work can feel confident that they will be treated fairly and if there is confusion or questions, the owner of the company will discuss any concerns you have."

"Jim was very helpful and personable to work with.  I had recently moved to the Huntsville area and was unable to connect my wireless printer.   There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer.  Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS.  He was able to get the wireless connection to work as well.  He took the computer on a Friday evening and returned it Sunday evening in prime condition. 
A few weeks later I  got an error message while reinstalling my accounting software so I called Jim.  He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable.  I will definitely use his services again.

"Where do I start.... I called Dave once we closed on our house. The entire Interior / trim needed wallpaper removal, and fresh paint. Luckily I had and empty house to work with for about a month. He made sure he squeezed me in before we moved, which was a huge plus. After discussing my budget, we came to an agreement on a price that was more than reasonable. He and his team worked day / night / weekends to make sure it was done on time. I took forever to pick out colors, etc... and he never was impatient with me. He finished 90% of it on time, the other part was because I couldn't make a descision on color for that area. He came after we moved in and knocked that out promptly. Any touch ups, fixes etc that were needed, he came and did with no issue. He even took the liberty of going out and purchasing all the new air vents, and other things we needed. He even came back and repainted the kitchen completely after we wanted to change the color. I would highly recomend his company, and will use him again. Stand up guy."

FAQs for air conditioning projects in Sterling, 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.
