"Tony Flowers from Cold Air Mechanical is a reliable A/C specialist/technician, who replaced/repaired my home A/C system which had a defect coil that leaked freon and a near burn-out compressor under the extreme hot summer, August 2025. Tony managed to have both the defect coil and the compressor replaced by the manufactory under the warranty – it saved me a lot of money. In addition, Tony had followed up the A/C supplier store to have the cost of new coil refunded to me as under warranty. Tony conducted phone calls with the supplier store in Austin, which drove him to the supplier’s corporation finance department to get the refund completed. I strongly recommend Tony Flowers from Cold Air Mechanical to anyone who needs A/C service. Thuy Nguyen Pflugerville, Texas"

"Mr. Justin Craig from Bob Jayâ s Heating and Air Conditioning installed a 4-ton 16 seer Daikin Fit Heat Pump system at our home. Along with the new air conditioner, Justin corrected an air flow deficiency by installing an additional air return and ductwork. He also brought the system up to code and replaced the thermostat. Daikin provides a 12 -year parts, 12-year unit replacement, and 2-year labor warranty. On our 16 seer unit I had the option to purchase a labor contract through Daikin which would extend my labor warranty to 12-years. The 12-year parts and unit replacement warranty is uncommon and very refreshing in the air conditioning industry. It must be noted that for the system to be eligible for replacement under the warranty provided by the manufacturer, Daikin requires proof of regular yearly maintenance. The excellent work done by Justin has solved our air conditioning needs. Customer service and timely responses to requests for information are the trademark of Justinâ s work. I would recommend Bob Jayâ s and Justin Craig for any air conditioning work you need done. Thank you Justin!"

"Excellent work. Arrives on time and very personable. Installation of ceiling fans was done professionally. Had ordered one fan that was too small for the room. Was advised what to order and what to order for another room with high ceilings. Sent back small fan ordered two new ones and Don from Enoch installed the new ones. Had trouble with air conditioner cutting out and noticed it was tripping the breaker switch. Don arrived again, diagnosed the situation. Breaker switch was too small for the air conditioner. Installed correct breaker switch and everything running smoothly. *This review was migrated from an affiliated account on Angi with an original submission date of 8/27/2016."

"My kitchen lights were not working and my property maintenance company sent Dean Electric to my home. John & John were efficient, communicated the time they were coming out, were on time, friendly, and explained the details of the problem. They resolved the issue quickly and I felt that comfortable with the job and that they were knowledgeable in the work/service that they performed. Customer service was awesome. Perfect gentleman! Thanks so much!"

"The reason for the 4 rating and not a 5 is the sales part of the experiences not the technicians and the work done. Larry was the technician for my water heater. I have previously written a review for the AC installment. Larry is amazing. He has a lot of experience but what impressed me more was the fact he was totally honest & cared about my experience as the consumer. I was actually told by one of the salesman that Daniel’s prices are higher than other companies. He was correct. They seem to want to immediately try to sell a new replacement without considering the customers situation. My water heater is only 15 months old but I clearly got a ‘lemon’ and it took 3 major parts to be replaced before it was fixed. The parts were still covered by the manufacturer warranty but the labor was not. After several trips it was fixed and from my conversations with the salesperson I felt he was pushing for me to purchase a new water heater and not really understanding of the fact that I had just replaced my AC and my water heater was only 15 months old. In the end, Larry, the technician, did the right thing. It has been a week now and my water heater is working fine. I appreciate honesty more than anything when dealing with these things. I feel like I got it but it took some extra pushing on my part and a technician who stood by what he said. The owner or rep of owner replied to my previous review on the Daniel’s site. I hope this review gives him the answer to why I have not given 5 stars for either review."

FAQs for air conditioning projects in Harker Heights, 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.
