"My air conditioning condenser went out the fan stoped blowing on the hottest night of the year. He contacted me right away the next morning at 9 am and we made an appointment for that afternoon a Saturday that was forecast to be over 100 degrees . I was expecting to be told I needed to buy a whole new condenser unit and I wouldn t have air conditioning until Monday. Crossing my fingers that it wouldn t cost more than my credit card limit. He came and gave me a fair quote for a new unit and also quoted me for a repair he said should keep the unit running for three or four more years. He showed me the most cost effective solution to my problem. He explained the pros and cons to each scenario. What I thought was going to be a financial crisis in the thousands of dollars and a weekend of sweaty misery. Ended up in the hundreds and I m sitting in my living room enjoying the air conditioning all before 3pm. Best service I ve ever had !!!"

"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."

"Chad arrived on time. He and his crew were very courteous and professional. He and I had both initially thought that I had a slab leak based on the symptoms. But once Chad got an air compressor hooked up to the water line to blow the water out, he found the leak to be in the yard where a landscaping crew had capped off the old sprinkler system with the incorrect fitting. He and his crew got the problem solved in just a few hours. The price was considerably less than what we talked about if it had been a slab leak, so I was very pleased about that also. I would definitely recommend Chad and Priority Plumbing."

"The lady that answered the phone was very polite and scheduled the appointment to my convenience. The tech. Arrived 10 mins early and presented himself very professionally also his van looked very nice. Upon diagnosing the problem he explained all my options and gave me his recommendation as to what my next step should be. I decided to replace bad part and get the air conditioner tuned up. I'm was extremely satisfied with the level of service I received from mechanical comfort systems, and will use the company again for future repairs and maintenance.

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.
