"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"

"They didn't come on time at all.  The issue I had was that they had a price advertised for a system check and when they came they said that I had two different air conditioning units and it would be two different prices.  I felt that was a bit misleading and they didn't say that when I called to make the appointment. The guy that came was fine.  He was great.  I was happy with the service.  I just felt mislead."

"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."

"TONY HERRIN is our all time favorite heating and air conditioning professional. We've been blessed to have known him for 23 years. He is always thorough and explains all the work he does, while giving us an update on the system check list important for its continued peak performance. When any repairs have to be made, his work is of the highest quality. My wife and I ask for him every time we call for maintenance or service, and we're willing to wait for an opening in his schedule. Horne Heating and A/C recently merged with Quality Comfort Heating and A/C and they are continuing the fine service we came to expect with Quality Comfort. Top notch organization!"

"This was my spring check up on air conditioner before running.. Everything went very well. Everyone should have a service contract with GSM they are the best. I have tried others but they do not compare to GSM."

"The A/C repair technician (Jonathan) was very thorough in his troubleshooting. He is extremely knowledgeable and clearly explained the diagnosis and repair options. He explained the immediate repair as well as issues to anticipate with my fairly old (15 year old system), including the caution that my systems R22 refrigerant is no longer being produced and is becoming cost prohibitive to replace (I.e. for recharging). T.Byrdâ s gave an excellent price for the parts replacement and repair. Jonathan also explained the efficiencies of current models and a ballpark figure and timeframe that I could use in planning for a full unit replacement. Outstanding work, outstanding on-site customer service. And special thanks to HomeAdvisor & Angie for including T.Byrdâ s Heating and Air, LLC among the referrals for obtaining estimates and service date availability. This has been a great experience and it was a big deal for our A/C to fail just as the Charlotte summer heat had gone Inyo the 90â s!"

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.
