"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."

"We recently had a new HVAC system installed by Webb Air and had a great experience. The technicians were professional, knowledgeable, and took the time to explain the system and answer our questions. The installation was smooth, the work area was kept clean, and everything works perfectly. It’s clear they take pride in their work. I would definitely recommend Webb Air to anyone needing HVAC service."

"????? Excellent furnace service ? highly recommend Caleb with Always There Air did an outstanding job servicing our furnace. He was punctual, professional, and extremely thorough in explaining what he was doing and what to watch for going forward. You can tell he genuinely cares about doing the job right, not just rushing through a service call. He took the time to answer all of my questions, made sure everything was running efficiently, and left the area clean when he was done. It?s rare to find a technician who combines strong technical knowledge with great customer service, but Caleb absolutely does. I wouldn?t hesitate to use Always There Air again and will specifically request Caleb for future HVAC needs. Highly recommend."

"My AC just stopped and the home was not cooling even when the AC was switched on. I approached Anji and I picked Prince technician from the Varsity Zone . In few minutes he came over the same day and fixed the issue. He even briefed me on all the work he was going to do. In less than 30 minutes my Air condition came back to life . The house was cooling back again. Thank you Varsity! Thank you Prince."

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.
