"Outstanding service from rescue air. I just got my AC serviced and Roman was extremely knowledgeable and helpful. Roman fixed my air conditioning issue with ease. I am very inquisitive and all of the questions I asked were answered professionally. Roman educated me on some aspects of my HVAC system. My wife will be please with me now that we have cold air blowing."

"Air conditioning stopped working on a Wednesday. David sent out a technician that afternoon to confirm the compressor was bad. The next day a crew of 3 came out in late afternoon and installed a new A/C unit (old one was 28 yo) and a new furnace (old one was 30 yo). I stuck with RUUD/Rheem due to good experiences. The crew was efficient (3 hours to do both installs), the A/C is working great with cooler air and more forceful blowing, and they briefly checked the furnace operation also. My old unit was a 10 SEER operating probably at a 7 efficiency lately and my new unit is a 14.3 SEER. I found everyone polite from the owner to the workers, addressed my needs, and answered my questions. I still use my old thermostat which is Honeywell programmable while the one they gave me was Honeywell non-programmable. And BTW, David said I probably would raise my thermostat a degree or so with the new unit, and I did without any loss of comfort. Finally, the price was the best I found."

"HVAC system went out and needed a new one on short notice. Team Enoch responded the same day and were out 2 days later to replace the HVAC system. Installation was done meticulously and with great care and the price was very fair. We paid about $6000 for a 4 ton American Standard (aka Trane) system. The first company that quoted me estimated $8900 for the exact same system and undoubtedly lower quality of work (Abundant Air Condition and Heating). Miles was my point of contact and did not try to push a sale and encouraged me to do some research for myself. Overall great experience, will definitely call again if anything else comes up with my electrical/plumbing. *This review was migrated from an affiliated account on Angi with an original submission date of 7/27/2019."

"Just got my entire AC system replaced and it was a really smooth experience. The team was easy to work with, showed up on time, and got everything done without any hassle. The 0% financing was a huge plus and made it way more manageable. Everything?s working great so far,definitely recommend!!!"
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.
