"I called to set up a time for getting a quite for cleaning my heat =pump ahead of winter. He came over and did my heat pump PM and inspected the air vents in my crawl space underneath the house. I was shocked when he showed me the pictures. He then worked up an itemized quote to cover needed repairs. I felt like he gave me a fair estimate and was even open to working with me on the cost. We set a schedule for him to start. He started and finished the project as scheduled. I love how he works and would highly recommend him to anyone needing heating and air system work done. I will use this company definitely for future projects"

"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."

"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 and Mike returned my call quickly and set up a date.  He came and checked the air conditioner.  He did not try to convince me it needed any else other than a check up.  Was quick and efficient and mannerly.  I would certainly use him again even for more serious repairs.

"From start to finish a great experience! Called with no air conditioning yesterday, a Friday holiday weekend. The lady that answered the worked wonders and found tech close by that could come the next morning. I received a call the tech was going to be earlier than expected. Great news on a hot day with no air. The service was efficient and fair priced. Within a hour my unit was up and running again. The sales office followed up right after to schedule a time to look a future options since my unit is getting up there in age. No pushy sales. Professional, quality service. I will use them in the future and highly recommend this company."

"I guess the price alright. It's about what we paid in Charlotte with another company, maybe just a tiny bit less. But I guess it's the what the prevailing rate is. We had somebody else to do the work, and they didn't do; and we paid them more. We have signed up to use them for our maintenance service for the furnace and air conditioner."

FAQs for air conditioning projects in Gastonia, 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.
