"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."

"Awesome. While I probably could have scrounged around for a slightly better price, the speed, professionalism and quality of the work more than made up for it - and currently being unemployed, I don't say that lightly! They literally came THE NEXT DAY and did the entire install - remove old unit, rework the ducting, install an air cleaner, dress the wiring - all in one day! The job was done with expert quality - no loose wires or hoses lying around, everything square - and they even came back a few days later to make sure the sump pump and humidifier wire working correctly. finally, they called me a week after that, to make sure I got the Peoples Gas rebate paperwork together! I'd recommend them to anyone!"

"Home Comfort Systems replaced my old air conditioner with a new American Standard air conditioner. The day it was going to be installed, one of the owners, Steve, stopped by to look at the old air conditioner, and explain what was going to be done. The installers arrived an hour later, explained to me exactly what they were going to do, and all the specs of the new air conditioner. Roughly 2 hours later, they were finished. They explained the warranty, and cleaned up. The only evidence that they were there was the new air conditioner, no debris left behind. They were very professional, and I would gladly use them again!"

"Andrew and his assistant were very professional in their approach to cleaning our air ducts and dryer vent. The services they provided were totally consistent with how they describe their approach to the service they provide. This included the very helpful before and after pictures taken which would convince anyone of the need to have this work performed in their homes."

FAQs for air conditioning projects in Northbrook, 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.
