"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. "

Customers say: True professional

"When we purchased this house 20 years ago, we hired a different company to replace the furnace and air conditioner. There was very little flow so they replaced several of our runs also. After all that work and expense, we were forced to run two window a/c units along with our central air. Yet our house still would not cool! We were extremely frustrated. When we hired One Hour Heating and Air Conditioning, Phil was sure he could help us. And he did. We cannot believe how wonderful our house cools. Phil was very accommodating, as we had to split the installment dates for the furnace and air conditioner. He always returned our calls, answered all our concerns, was timely, efficient and professional, as was his staff. His service and equipment exceeded our expectations and we give One Hour Heating and A/C our highest recommendation."

"I had the opportunity, and the pleasure, to work side by side coordinating with the office manager Maggie. She was so intentive with all my needs and always made it easy to get my questions answered. Maggie kept me informed on every step of this very large process from scheduling a crane and road crew, to getting permits and having the work inspected. SHE MADE THE WHOLE THING SIMPLE. Now the work crews worked quickly to get things running for us. The original plan was to take two days getting the old air conditioners down from the roof and then the new ones up and running. The crews had everything done in less then a day. I could not be happier with my experience with Phoenix HVAC!! I will definitely hire them again!"

FAQs for air conditioning projects in Wauconda, 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.
