"Our AC went out in the middle of summer and I called to schedule an appointment and they made it out the same day! They were very professional and completed the necessary maintenance extremely quickly. We had air again by the end of the day. It’s also one of the most affordable places we’ve ever used for our heating and air maintenance and repairs."

"Will and Eddie from CHEEKY Heating and Air came out today to install the 5” filter replacement on our Air Handler. Additionally, he and co-tech Eddie installed an additional return air vent and line to our overall system. Will seemed to be thorough and knowledgeable of all aspects regarding the installation. During the installation and completion of the work, Will kept us informed about the install progress and made sure there was “no mess left behind” when work was done. Thanks Will and CHEEKY for your trusted HVAC installation."

"I found Cool Air via web search for AC Tune Up. They were offering a $39 system check which worked for me. Setting the appointment was very easy and straight forward. Jerry came out the next day and called 30 minutes prior to arriving. He was gloved masked and had booties covering his shoes before entering my home. He was very knowledgeable and made a number of no pressure recommendations and system additions that I didn't feel compelled to have installed. Jerry's approach was more as a consultant vs service person. I like this and would use Cool Air in the future."

FAQs for air conditioning projects in Norcross, GA

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.
