"Our air went out at the start of summer during an extremely hot period (90's+!). Due to the way our place is set up, it was a REALLY tough install that required using a crane to get the AC on the roof, and pulling the water heater - which it turns out needed replacement also (ugh!). Rich came to our rescue, even loaning us a portable AC that we could use until the install could be done. He worked hard, and coordinated well with the plumber we had in to pull/replace the water heater. He was friendly, very flexible and did good work. We're very happy with the service he gave us. On top of all of this, his price was very reasonable. Much less than the other guys and some of them took one look at our system and flat out refused the job! I highly recommend you call Rich and skip some of the "big names" in town that want to charge more, and work less hard for you. Its rare to find service companies these days with a solid work ethic, who deliver great service for a fair price."

"I had some remodelling work done in the kitchen, getting new countertops. Kelly came to disconnect the old sink drains, faucet, and dishwasher in the morning before the countertops were installed. Following installation and allowing 24 hours for the silicone to dry, he returned to connect the new sinks, faucet, garbage disposal, and dishwasher. This included re-arranging the sink drains and installing cutoff valves for the hot and cold water lines to the faucet. It took a couple hours, but the job was perfect. Kelly is a great plumber, and I'd be pleased to work with him again.

"I received prompt service when setting up my appointment. Gentleman came promptly at time specified and gave a thorough estimate on what it would cost for system to be fixed. I also received options on how I could repair system with different money levels and the differences of warrantees. I was extremely impressed at how quickly my home was serviced."

FAQs for air conditioning projects in Champaign, 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.
