"Outstanding!! Called on a Sunday, when they are not open and left a message. Received a call back the same day and they sent a technician out the same day as well! They confirmed what we already knew, that we needed a new unit. Ours was 25 years old and quit running in 104* weather! They gave estimates and were very prompt and helpful on the same day, (Sunday.) We were able to choose a unit best suited for us and they answered any questions we had all within hours of us calling them. The next day on Monday they came to our house and started work when they left Monday, they were practically done! Had the unit there and running and had enough vents hooked up to keep us cool and comfortable until they could come back the next day. They had also enlarged our return air duct and filter which we had wanted and needed done because ours was too small to cool the house correctly. And installed a new smart thermostat that needed additional wiring at no charge that we had bought. They did a duct pressure test, removed all the air supply registers sealed them with insulation tape and replaced the registers, fuel gas piping and condensate piping, and removed old unit. They arrived early the next day (Tuesday) and in about 2 1/2 hours they were completely done. Everyone of the employees deserves a huge THANK YOU! They were so friendly, informative, knowledgeable, professional, and hardworking. We can't say enough good things about our experience with them. We will use them for all our needs from now on! Thanks guys, you were absolutely GREAT! Job well done, over and beyond. If we could give more than an A we would..."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Thomas was on time, checked the unit, repaired it after giving me a quote.Replaced my air filter cleaned up & was done."
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.
