"This was my second quote and this company is amazing. Quickly identified the issue, changed the motor, provided a filter and made sure everything was working on one trip within a few hours. The previous company (Air Pros, LLC) said it was unfixable and tried to sell me a new unit over $6k which was a huge scam. Don't go to those guys, work with this family owned honest business. Keep in mind HVAC repairs in many cases are not cheap, I own 3 houses and have paid several hundred or more when an HVAC is old and need repairs."

"Atlanta Air Authority was thoroughly professional throughout the process of replacing my HVAC system. And their good advice even saved me money. They were able to do the job the day after I agreed to hire them, showed up on time, did a very professional installation, cleaned up the work area and hauled off the old equipment. I couldn't be happier."

"I would give 10 stars - the whole experience was great. We had dreaded going through the process because past experience with HVAC contractors had us conditioned to expect a lot of stress. However, TE Certified was fantastic from start to finish. The first technician who came to diagnose the problem was really good, exactly on time and very knowledgeable. He immediately recognized the issue and explained it clearly, offering several options for how to deal with it. We chose to replace the unit, and the next day the estimator came out. He was really good as well, giving helpful information and offering several options and prices that would work for us. He was also exactly on time, very friendly and not pushy at all. When the installers came to do the work, again they were exactly on time. Both installers were very friendly and professional. They worked efficiently and spent time showing us how to use the new thermostats. We were highly impressed with everyone from TE Certified and plan to stay with them for all maintenance, as well as for any other services we might need that they offer."

"All Seasons Heating & Air is a friendly, fair, honest, ethical and professional company. I communicated with Brant and was very pleased with his patience to explain things to me and his honesty in not trying to sell me a new unit if I didn't need one. He blew out the pipes of my old unit and now everything has worked perfectly since then. I would highly recommend this company to anyone. They are better than the best!!!"

"The ASSA MECHANICAL SERVICES LLC Team showed up promptly at the previously agreed, confirmed day and time. They immediately got to work with removing the old window mounted air conditioner unit which needed to be replaced and installed the new air conditioner. The whole process only took about one hour. A very professional and communicative team. The new air conditioner is working great. We’ll be requesting these guys again for any annual maintenance required for the window a.c. unit. Thank you ASSA MECHANICAL SERVICES LLC. Arthur"

FAQs for air conditioning projects in Cumming, 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.
