"I am very satisfied with the product and the service provided by Cool Air Mechanical and their technician, Sean Haynes. Sean did an excellent job of installing an air purification system. Sean also performed the annual checkup on my A/C system. I highly recommend Cool Air Mechanical and especially Sean for any air conditioning service."

"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.

"I did a quote on Angie needing help with my newly installed HVAC system in my recently purchased home. Kevin was the first person to call me, I explained what was going on he asked a series of questions and eventually referred me to the installer of the system. Informing me there should be a minimum one year installers warranty, to figure out whom installed it and to get them back out as to not void my manufacture warranty by allowing someone else work on the system. I received and used information from my broker and the same day 4/24/26 called the original installer and they are coming today 4/28/26 to fix this brand new system. The Peoples Champ Heating & Air, will be my go to experts once this courtesy one year warranty is up for sure. Thanks Kevin. For being a honest decent person, caring more about your craft and building relationships then making a Buck."

FAQs for air conditioning projects in Mcdonough, 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.
