"Andres was amazing. My father had a stroke in January and our a/c unit stopped blowing cold air completely. I was concerned for his health and needed someone immediately. Not only did Andres come out in less than 2 hours, but he drove from Katy to Rosenberg to do so. He went through and made sure to thoroughly check what the issue was. He gave me several options and a maintenance plan that will save us a great deal of money. He made sure to listen and to provide the best plan of action possible. This is my first time using HomeAdvisor and couldn’t have had a better experience."

"TeamEnoch replaced my old air conditioning and heating systems, and the work they did was so good it borders on the unbelievable. Two very professional technicians showed up exactly on time, worked for 11 hours straight in really horrible conditions (a cramped attic in 95-degree heat) and did the whole job in one day! To top it off, their company’s price for all this was significantly lower than other estimates I had. This is a great company. I can see why they have won so many awards. *This review was migrated from an affiliated account on Angi with an original submission date of 10/4/2021"

"They check my air conditioning and heating systems every 3 months"
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.
