"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."

"Installation of a new furnace and air conditioner was done. We were so impressed with the professionalism and follow through of the CR Mechanical team. Rick contacted us promptly and advised us of our options and his recommendations for our project. We did some additional homework and decided to hire CR Mechanical. Craig arrived on schedule and installed the furnace and did some additional pipe work the first day. On the second day, the AC was installed on the new compressor was relocated to a new area that we had discussed. The job was completed as agreed with efficiency and neatness. I would recommend CR Mechanical with hesitation."

"I have lived in my home for over 23 years and have used several different Heating and Air companies thru the years... I needed service in Sept 2018 and had various coupon prices of $39 and $49 for an A/C tune up and was about to chose on of them but decided to check Angie's list for a review or google for the coupon companies. That is when I found American Family HVAC and started to read their reviews.. For some reason, I decided to use this company even tho the cost was a bit more money and boy am I ever happy that I went with my hunch. Sometimes it is NOT always about the money. I was really looking for an A/C furnace company that I could count on and use regularly. Not only was the repair gentleman that came out, on time and very thorough and professional but he spent a long time and I feel that I received the most thorough tune up that I have ever had. Josh, the service tech was just a delight and the best part was that this company has a membership contract that I was able to purchase. It is a small monthly charge monthly and . I get 2 free tune-ups a year included in the monthly fee for NO charge and if I need any service work I get 20% off of the charge and same day service...all for only $12.95 a month. What a wonderful idea and I cannot express how happy I am with this choice. It is a win-win deal for me and the company. I am a very happy camper with my choice of this company."

"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."

FAQs for air conditioning projects in Lake Zurich, 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.
