"We scheduled a 4 pm appointment. By 4:45, no one showed up or called to confirm their whereabouts. I had to call Metro Air and ask what was going on. The secretary said she will dispatch a technician to my house. The technician did not arrive until 5:30. He was kind and was able to fix the capacitor, which was causing the issue. About a week later, their office followed up. I told the lady that the a/c was on, but now there was another sound coming from the system. The secretary indicated that the technician would call me that day to discuss and set up a follow up visit to address the issue. No one ever called."

"This Guy is a real pro at what he does! I don't have enough words to express my appreciation with the Job he did in my attic with the air conditioning ducts. Besides being an excellent air conditioning pro he is pleasant and honest. I had interviewed 3 other companies for the Job and I decided to go with him. The minute He went in the attic he asked me all the right questions. Questions to better replace the ducts in my two story condominium. since the air condition unit is in the first floor he needed to find the ducts on the walls in the second floor and figure out where they where. There was a duct that went to my kitchen that has never worked. He figured out that the duct came up the wall trough one of the closets. He opened a small hole on the sheet rock and fished out the duct and connected it with the other one in the attic .My home is actually cool for the first time since I moved in and I have and air condition kitchen."

"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."

"He works on Sundays for no extra charge. When I did the request to be contacted by three companies, he called within 30 minutes and was at my house two hours later. Haven't heard from the other two. Very professional. The charge was $300 to unplug lines in air conditioning units (2) and install safety valves that will turn off A/C if leaks occur. I called because my house smelled like mothballs!"

FAQs for air conditioning projects in Duncanville, TX

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.
