"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."

Customers say: True professional
"Based on the work that was done at my home between April 17, 2025 and April 21, 2025, I strongly recommend Jopat General Contracting (JPC) and in particular John Oke . JPC is based in Aubrey Texas (940–202–0103) and John is one of the three co-owners. I discovered JPC through a search on Angi. I wanted a recommendation for help in the next two days. John replaced three burned out LED light fixtures in our kitchen ceiling. Intricate wiring had to be sorted out and prepped before new LED light fixtures could be wired in. We also had multiple problems in our master bathroom requiring a diagnosis and replacement of a malfunctioning shower head and tub faucet. We also needed shelves for a corner of that bathroom. John showed up on time on three occasions and kept us informed with texts and verbal explanations. He had to make multiple trips to a Home Depot in Roanoke for needed supplies because of problems he discovered. There was no additional charge for those trips beyond the original estimate. I doubt he anticipated that multiple trips for supplies would be needed but he never tried to assess an additional charge. I've gone into this detail to explain why I feel like strongly recommending John and JPC. In short, I feel like the work was well done and reasonably priced and done efficiently with multiple problems diagnosed and fixed. Alan Laufman"

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.
