"First off, If this guy serves your area, you need to call him and give you a chance. After another nameless company came out and inspected the problem, gave me the price tag by giving me a range from 1500 up to 2500 and suggested i might need a whole new unit. I called Billy from Select Air because of Angies list reviews. The man answered his phone promptly and when a message was left, he called me back quickly. He was punctual. Never stood me up and never kept me waiting. He walked in the door and had this echo of trustworthiness reserved for superheroes. 
I had told him about the problem and the first company that came out, he tested what they thought was the problem and verified the evaporator coil was in need of repair. And he walked me through everything from pricing, to why and what to expect. Although he couldn't help me right away because a part was needed and I had to put some scratch together to pay him, he helped me mitigate the problem until we could schedule an appointment. He provided advice for how to set the thermostat so that the pipes outside wouldn't freeze over. (which is what was happening). We were lucky to have a week with highs in the 70's for a few days to keep the temp in the house down. 
Since it's been fixed, I finally understand how broke my system actually was. He definitely fixed the right part. I can't recommend this guy enough. I'll be purchasing his annual checkup program once I recover from the cost of this fix.

"Aire Serve Lake Worth TX did a phenomenal job servicing our gas furnace during the freeze 1/26/26. I called at 9am Monday and scheduled an appointment for between 10am and 2pm. They notified me when tech was in route and arrived at 10am. Tech Chandler Smith was professional, knowledgeable, and a pleasure to deal with. After some troubleshooting, he was able to restore the system and get us the much-needed heat turned back on. I absolutely recommend their service. From my initial call to their office to the closing of the service call was impressive."

"I had a terrible experience with a previous contractor who charged me $2,700 and didn’t even fix my AC. Luckily, Mr. David from Air Bear came out, located the issue immediately, and explained everything thoroughly. Air Bear is a very dependable and honest company. If you want to support a fantastic Veteran-owned business that does top-notch work, look no further. I cannot recommend them enough!"

"I hired Manny from Angi. He and his co-worker Abel came to my home last week to verify that my A/C needed replacing. Manny took the time to inspect my unit and found several mistakes the installer made 10 years ago. I got a quote that was several hundred dollars less than another A/C company. I scheduled Manny to come out today to do the job. I could tell from the beginning that Manny and Abel knew what they were doing. While Manny was disconnecting the condenser, Abel was in the attic tearing out the old unit and began putting in the new coils and return air duct work. The job took 6 hours. When they were finished, I inspected the completed job. It was an amazing transformation. The A/C was cooling the house until it became frigid. With the new thermostat everything was easy to program and use. I would recommend Manny and Son Air Conditioning and Heating to any one whom need any type of work done on their heating or A/C. They are trustworthy and dependable."

"Our 15 year old air conditioning system gave out and so we began to gather quotes. We requested several quotes from home advisor. Prime ac was the only company that showed up on time, performed a full evaluation and had the quotes ready same day. Install was done the next day and everything went great. Thank you for the wonderful experience and treating us like valued customers."

FAQs for air conditioning projects in Keller, 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.
