"Excellent service from my first call to Hope and then Linda who explained in complete detail what would be required to service my air conditioner and the cost. The servicemen, Branden and Jose, were very professional and went over my HVAC unit completely. The only access to the unit’s condenser coil is from the outside which needed to be cleaned/hosed down. I’m in a 3rd floor condo which requires an extension ladder to reach. Most HVAC service will not go any higher than 25 feet but the Shavitz servicemen had no problem reaching my unit which is approximately 35 feet up. Price for the service was a little higher than I expected but I fully understand after observing the work done. I will highly recommend Shavitz to others in my condo building including our building manager and also anyone who is in need of HVAC service. Great service from my initial call thru service completion."

"I was very happy with this company. They did not try to over sell me stuff I did not need. This is a real plus. They were friendly professional and cleaned up after themselves. All my questions about the unit were answered so I understood what they were talkin about. Their pricing is reasonable. They promptly provided info I needed to get the permit from the village for install. There is nothing negative about my experience with them. I believe from my experience with ALL TEMP Heating and Air Conditioning was fair and honest. I will be recommending them to others as they were recommended to me"

"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."

"Thought it was a plumbing issue, but turned out to be an issue with air conditioner. They were prompt in responding to the emergency call. HVAC responder was knowledgeable. Price for furnace and AC was horribly overpriced!"

FAQs for air conditioning projects in Crystal Lake, 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.
