"The owner, Steve, came out and explained everything and more that I should be aware of regarding the replacement of the 26 year old furnace and Air conditioning units. He was a pleasure to work with and the price quote was more than acceptable. I did accept and within the week the crew arrived to do the installation. Al and Damien were very professional and the work was extremely well done. They finished that same day and when they left it was if the new units had always been there. I was extremely impressed and will certainly go back to them for future maintenance. You can't go wrong with this company!"

"Francisco of United Heating and Air Conditioning is the greatest, and I will hire him again happily and hope to have him service my system yearly going forward. He came today as promised and found that my thermostat only needed batteries, but my system was otherwise fine. He is very good and extremely honest and informative."

"The men were very professional and fair. They tried very hard to fix the AC but the unit was deemed beyond repair. It was leaking coolant somewhere. They said they could give me a very good deal on a new AC with all parts and labor included if and when I choose to replace the AC unit with them. Even though the unit was not fixed because it was frankly beyond repair, I am still satisfied by their dedicated effort, honesty and professionalism. I will most likely buy a new AC from One Hour AC of Naperville in the near future."

"Issac was here to chemically clean the air conditioning unit. I've never seen such a dirty unit! He came out and did a great job even though he wasn't feeling well. I'm a nurse, and he decided to stay and complete the job, even though I told him we could reschedule so he could go home and get some rest."

"This company arrived on time and took much care in cleaning our furnace and air conditioner. They took it all apart and cleaned every part of them carefully. They were very personable and knowledgeable about the systems. Even had them clean the humidifier. It was a total of $190 for all of that. They also have a 15% discount if you join the repair club and the service call goes towards the service call. Service call is $89.95. These guys were great! Would hire them again. We are planning to have them clean our furnace and air annually. Thank you."
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.
