"Tech came out and informed me my old unit (21 yrs old) was leaking freon which was why the a/c wasn't cooling the house. I would need to have the leak fixed and the system recharged, which would have been expensive. Since the unit was so old, I decided to get a quote for a new system. I received the quote the following day and installation was scheduled for the following day. Crew arrived on time at 8am and proceeded to remove/replace my old unit. There was some additional duct work that was needed which was done at no charge since it wasn't included in the original quote. The crew completed the work same day. The supervisor inspected the work, installed the new wi-fi thermostat, and showed me how to use it. It's been about a month since installation and I have had no issues whatsoever. Highly recommend!"

"Butch called back right away. Came out in a timely fashion. Got one unit working. Then he said the main board was malfunctioning on the downstairs unit and would have to be replaced. It would cost 1200 or 1300. But if we spent a little extra on a service contract he would wave the trip fee and it would be 1100 something. Okay. We did that. It was too late for him to get the board that day so he came out the next day to install the board. But the unit still didn't come on. He said the thermostat was bad and it would we 300 to 500 to replace the thermostat depending on what we wanted. My husband told him we could do that ourselves. Just by pass it and get the unit working. Then he came down and said that the blower motor was out and it would be 1800 to replace the blower motor or 2400 to just replace the whole unit and then we'd be under warranty again. I told them I wanted a second opinion before we did that. I called Ed & Sons they came out, confirmed that we did need a new thermostat. And said they could rebuild the blower motor for around 100$. I ordered two new thermostats for 300 for both of them and my husband installed the thermostats. The work they did was fine. But I felt like they were more of the school of let's just replace parts until it works or we can sell them a new unit. Rather than what can we fix."

"I have nothing but good things to say about this company. My old Ac unit died on a Friday eve (Labor Day weekend) so I put in a service request. I was called near immediately and they came out the next morning to evaluate. By the end of the day the following Tuesday I had a brand new central air system at what I thought was a very fair price. The company owner JR came out several times to check progress. His installers were polite and professional and I was kept up to date on the arrival times and completion time estimate. Highly recommended."

"Booked a same day appointment because my A/C wouldn’t come on and I’d already tried what I could on my own. Mordi and Sean got to us in about 30 minutes, which is honestly impressive considering traffic these days. They were courteous, quick, and mindful of the noise since my toddler was napping just down the hall — one less thing I had to worry about. They had the system up and running quickly and charged a fair price. They even swept the area before leaving and went out of their way to respect the house. Really appreciated the quality of the work and how personable they were. Way better experience than I’ve had with other companies.​​​​​​​​​​​​​​​​"

FAQs for air conditioning projects in Cedar Park, 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.
