"We decided to use Shavitz Heating & Air Conditioning as the company for the install of our new furnace. What impressed us about Shavitz was their employees. They made the entire process a positive experience. Everyone that interacted with us had a friendly and professional demeanor. It started with the sales visit by Will Gutierrez who was a pleasure to deal with. He provided us with several options while never pressuring us to lean one way or another. He was patient with us and answered all our questions. His courteous approach gave us a positive view of the company he represented. The installing technician, Linas, and the tech that was assisting him only continued this professional trend. They both were equally as courteous. Once the work was complete, Linas made sure he answered all of our questions and that we felt comfortable with the operation of our new furnace and humidifier before he left. His patience was very much appreciated. He also made sure the area were the work was done was clean and all trash removed. Will Gutierrez followed up with us a few days afterwards to make sure all was well, and that we were pleased with the work and our new purchase. Our answer was a definite, yes."

"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."

"My experience working with CR Mechanical Services couldn't have been better. While looking to replace my furnace and air conditioner, I requested quotes from 4 different companies and CR Mechanical Services stood head and shoulders above the others. They provided a thorough HVAC consultation, listened to and answered my questions, and proposed a great new system at an unbeatable price. Rick and Craig just finished the installation today - right on time and right on schedule - and were friendly and professional through it all. My thanks to them, and my highest recommendation to all who are looking for an HVAC company."

AWE (Air, Water, Energy) did a great job. The installers arrived on schedule and worked all day to removed the old equipment and installed the new equipment.  When they were finished, everything looked great and the work area was completely cleaned up.  The air conditioner has worked great all summer and kept our house at a comfortable temperature.  I am looking forward to a similar experience with the new furnace, also.  After the system was installed, AWE sent an inspector to our house to make sure the job was completed satisfactorily (which it was) and take pictures of the equipment to make sure it was installed correctly (which it was).

FYI, we have been a customer of AWE for over twenty years because of the great service they have always provided.  This was the 2nd furnace and air conditioner we have purchased from them.  They also installed our current water heater.  The technicians are always very knowledgeable and friendly.  They always arrive when they say they will arrive, and do what they promise.  The services provided have always met or exceeding our expectations.  I would recommend AWE to everyone.

"He was very good.  I had some company coming from out of town and my air conditioning wasn't working.  He came that day to fix it.  He knows what he is doing.  He gets the job done.  He came within 1/2 hour of my phone call because he was in the area.  He got my air conditioner going right away.  It was really hot that day.  He took care of it right away.  He could have tried to tell me it was the compressor or something, but he didn't.  He was prompt, he did a good job, and he was fair.  He installed a furnace and air conditioner at my mother's house as well.  He did a good job there too.  He was here previously to try and quiet down my air conditioning, but nothing seemed to work too well.  He was really good on the installation, but I thought he was a little high on the repair. "

"Unfortunately, our homes and the systems that provide heat, electric, plumbing, etc. do not last forever and must from time to time get repaired and replaced. I have owned a home for over thirty four years. While over the years I have used many HVAC companies, I cannot think of a more professional, friendly, informative and quality heating and air conditioning company than One Hour Heating and Air Conditioning."

FAQs for air conditioning projects in Waukegan, 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.
