"Bill and Derrick worked hard to install attic fans and fixed the 3 ducts that were leaking from my air handler. Fixed batted insulation that was installed incorrectly and installed new baffles and insulation into my attic. They added insulation to the rear if the house as well. They took pictures of before and after. It was well worth the Money and it should pay for itself by lowering my electric and heating bill."

"Had service star Air & heating replace a 5 ton and 2.5 ton and two air handlers that had gone bad. Louis Ratti told me it would take his crew about 8 hours to completed the job from 9:am to 5pm. The crew got there on time and started to work right away. They were professional, courteous and proficient. There was no guessing to what they had to. They were good I say better than good. By 2:30pm they had both systems up and running and the work area clean and spotless. Not only that, I asked if they would connect my phone to both thermostat and with out hesitation they did it. I was very highly impressed. Thank you Louis for sending the right crew"

"Carl called and asked if he could come earlier than scheduled which was great. He removed all vent covers and cleaned them. While the vent covers were drying, Carl cleaned all of the ducts and the two return areas. Then he replaced all the vents. He was very careful and cleaned up as he went. I think I can already tell a difference in how the air flows in the clean ducts. I definitely would recommend Carl and Iron Air to anyone considering having their air ducts cleaned. Thanks Iron Air."

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.
