"It was a big deal. It was fine. He recommended that I get a brand new air conditioning system. The big deal was fine but the additional work was not fine. He said he would take 4 hours but he took more."

"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."

"Our heat was not working.  I called Moncrief and then sent someone out the next day.  There was a charge for them to come out (I want to say it was around $80).  They determined the control switch board needed to be replaced.  They did not have the control board for my unit, so they had to order it.  They said it would take a couple days.  They called a couple days later and said they had the part and we scheduled an appointment for the next day.  They installed the part and the heat was working again.
A few weeks later I turned on the air conditioning because the house was very hot.  I heard a loud rumbling that sounded like thunder.  It was coming from the air conditioning unit.  When I turned the A/C off, the rumbling stopped.  I called Moncrief and told them of the problem and they scheduled someone to come look at it the same day.  The guy determined that that the control switch board had not been calibrated, so he calibrated it to our unit.  There was no charge for this.
Everyone I interacted with was very friendly and helpful.  All appointments were set up very quickly.  I plan to use Moncrief again.

"Cesar came out to help when my AC wasn’t cooling properly, and he quickly diagnosed the problem. He found a faulty part that was causing the issue and repaired it, getting the system back to cooling normally. Cesar was professional, knowledgeable, and explained what needed to be done throughout the service. I had a great experience with Climate Heroes and was very happy with the service!"

FAQs for air conditioning projects in Flowery Branch, 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.
