"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."

"One of my existing AC units went out so I called 4 companies and they reviewed the conditions of all my HVAC systems. We determined that we should replace all 4 systems due to age and condition. Unique Air came out blow my other options and was able to schedule the job within 2 weeks. We are impressed with their pricing, customer service, completed job, and professionalism. We would Highly Recommend them to anyone wanting to repair or replace their HVAC systems."

"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!"

"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!"

"Reagan called to ask about my issue with my AC, and made time to come by my house the same day. He called prior to arriving and came at the time he said he’d be here. He was professional, courteous and informative. I would recommend him, and will absolutely contact him again for future HVAC needs."

"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."

"Josh came early to the appointment, introduced himself and immediately placed shoe covers over his shoes upon entering my home. He was beyond professional and explained everything that he found and the plan to repair the heating issue prior to getting started. He also made recommendations for maintenance but wasn't pushy in trying to make me buy anything extra. I HIGHLY recommend this company and will not only utilize T.Byrd's Heating and Air again, but I will refer them to my friends! Keep up the good work guys!"

"Accu-rite replaced my Lennox airconditioning unit with a new and more efficient unit.  I am completely satisfied with their work and how professional they were.  Again, I highly recommend using this company.  In fact, my son is building a new home, and Accu-rite will be installing 3 air conditioning units and  furnaces in his new home."

FAQs for air conditioning projects in Dallas, 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.
