"Zeno was very professional and explained everything he was doing and why. He was also very prompt which I appreciated as I did not have cool air blowing out of my unit, and it was very hot that day."

"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."

"Have used Ace & A Decatur office for 10+ years for all my heating and air conditioning needs.  They installed a new furnace & a new AC unit for me in the past, and I have renew my maintenance contract with them each year.  Their service techs have always been very professional, and the office staff very helpful.  I would highly recommend them.

"The technician diagnosed the problem and determined the capacitor was deflected. He replaced the capacitor and explained the purpose of the electrical part. I was extremely impressed with his knowledge of solving my problem. My only concern was that I thought the replacement of the part was exorbitant consisting the online prices of a capacitor for my air conditioning system."

"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."

"Hottest day of the year so far, and the guys were in a sweltering attic half the day. The other half of the day they were trying to decide how to hoist the LARGE air-conditioning unit onto a ledge without destroying the landscaping. They had to bring in a 4th guy and a long, wide plank. They put that unit on the plank and three pushed it up the plank while the fourth helped position it. The men were appreciative of the cold watermelon I gave them and I welcomed them to help themselves to jug of cold water in the fridge. They had a f ull day's work on day one, then on day two, one man returned to finish the ductwork and the installation of the vent.

"Steven was amazing. He was super flexible with my tentative work schedule. Communication was great, easy, simple. He is skilled, friendly, and intelligent- a great educator. Went above and beyond with what was required and did a thorough assessment and repair. My air was blowing warm, not cold. He cleaned the coils and taught us about the capacitor and changed it. He was honest and straightforward. I recommend Steven to anyone who is seeking professional HVAC assistance at a reasonable price from someone who isn t into frills, gimmicks, or upselling. This is your guy."

FAQs for air conditioning projects in Decatur, 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.
