"I hired Triad Mechanical to replace two heating and air conditioning systems. In general, I am happy with the work that was performed. However, there are two issues that would make me think twice before hiring them again. First, the work took longer to perform than I was anticipating. This was an issue for me because the air-conditioning was out on my upper level, and I have three young children at home. Second, the technicians did not do a great job of cleaning up after themselves. Among other things, I found screws and cigarette butts in the driveway that I had to clean up. This does not detract from the quality of the work, but it does make me question the professionalism of this company."

"We just had a full HVAC system installed by Ace & A, and couldn't be happier. Every step of the process was excellent from the initial repair call and scheduling, working with sales on a new system consult and the system installation experience. Because we were without air conditioning, they worked hard to get us in and scheduled a Saturday. We appreciated the professionalism, courteousness and, the number of years' experience -knowledge all of the people we encountered. We highly recommend Ace & A."

"I selected having my new HVAC (heatpump) system installed by Ragsdale based on the qualified sales consultation, the use of Carrier products made in the USA, and Ragsdale being a local certified family run business. My new unit was installed this morning by two technicians who worked efficiently and who kept me in the loop about the new equipment, thermostat, warranty, and FAQs. They were polite, neat & tidy. Well recommended."

"Le's heating an air conditioner an refrigeration are very professional gets the job done an really se of tje best workers i seen in a long time"
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.
