"On a grade for price I don't recall what the price was so I can't really comment on that.  One person came out to complete the service.  It took a couple hours to complete the service.  I don't really have much to say about them.  They just serviced our heating and air conditioning."

"Our new HVAC system was installed 12/20/2017. Our comfort level has decreased: We turn our heating down by 7 degrees F at night, but on cold nights the system takes over 4 hours to get back to the set daytime temperature. Acosta says we must not turn the heating down by more than 4 degrees. So we now have to choose between being too warm at night or cold in the morning. Supposed, this is because the unit is so efficient and not over-sized. It is too early to say if the higher efficiency shows up in substantial savings. The installers were on time and courteous. They did, however, leave the work area dirty, with left-over food and drink, and our garden tools strewn about. The crews explanation of the controls and electronic thermostat was rushed (after 6 pm) and inadequate."

"Excellent Aire Serve is a awesome company. Billy Bullard recommended a first rate Lennox heat pump for a low price. The Technicians were on time, very polite, and worked hard. They actually stayed over until the job is done. I am extremely happy with my new Lennox system, and would definitely recommend Aire Serve to anyone."

"I had another provider servicing my furnace, but after my home warranty sent KS Kamara Heating and Air to diagnos my problem, I learned that the previous provider was not doing what was necessary. KS Kamara Heating & Air, diganosed the problem, show me why I was having the problem, took care of the problem and now my system is running as it should. I then hired KS Kamara Heating and Air on the spot. I was amazed at what was found when he serviced my unit. I look forward to a continue business relationship with this company. May thanks to KS Kamara Heating and Air."

"I called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"

FAQs for air conditioning projects in Charlotte, NC

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.
