"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."

"My air conditioning stopped working this afternoon around 3 o’clock and by 7 Chris had us up and running again. He took the time to educate me on how to properly care for the unit and charged a more than fair price for the work. I would be happy to work with him again."

"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!"

"I sought a pro on Google who could do an air conditioning tune up and Neil of Mr.Furnace HVAC answered my call. He was about to finish for the evening but said he could pass by around 2130 to have a look at my unit. He was on time, very professional and assessed my issue and had all the materials to fix it right on the spot and at a very reasonable price. I would recommend him to anyone needing a/c work done as he is the boss of his company and as a result has very little, if any overhead so he is able to do the necessary repairs for a very good price."

"Central Heating and Cooling did an incredible job installing my new air conditioner units! From the moment they arrived, the process was professional, smooth, and efficient. A huge shoutout to Jesus Alvarado, who led the installation—he was knowledgeable, friendly, and went above and beyond to make sure everything was done right. He took the time to walk me through the new system, answered all my questions, and made sure everything was clean and perfect before leaving. The new units are running flawlessly and keeping my home comfortable even in the hottest weather. I highly recommend Central Heating and Cooling—and especially Jesus—for top-notch HVAC service!"

FAQs for air conditioning projects in Monroe, 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.
