"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 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."

"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!"

"Amazing, helpful, and caring. We had been working with another person for our ac work. Long story short, we started getting the run around. We started searching for another contractor, lo and behold, we came across Mr. Furnace. Before he even got completely in the attic, he knew what had happened. Let’s just say, the prior contractor left us in a mess. We had no clue the carelessness and danger the other contractor had put us in. Our gas lines were just dangling, the water line was shut off, instillation was coming out, and they had stepped on ducts and they were caved in. We were told if the gas lines would have hit a copper line, we would have all been in serious danger. Before they started the job they were hired for, they corrected what they could to ensure our families safety. They were very professional, friendly, and caring. We still have work to be done to get it all back correctly and will only be working with them from now on. Pricing is exceptionally reasonable for the job."

"Central arrived to help install a brand new AC system for my new home. The installers were very professional and cautious during the time of the install and they did a great job with the whole install! The end product was very clean and I will be reaching back out with any more HVAC needs!"

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.
