"Retired and moved to Texas. We had never lived in a manufactured home before but wanted to live at the lake and found a great deal. The home had an add-on that wasn't hooked into the central air and heat. I had to have this since the hot weather was coming. I had contacted two companies and they sent out their "salesmen" instead of the contractors who do the install. Both salesmen were in a hurry for us to sign the bottom line. Every question we had they just told us whatever they thought we wanted to hear. We won't deal with those types of businesses. I found 3 C's reviews and was blown away. Daniel and NIck came out, they explained everything and assured us everything would work great., We hired them right away and their work ethic and professionalism blew us away. Stop right now looking for a company, you will NEVER find a company like this, or another Daniel and Nick. I wish we had more for them to do. Thanks again for being the kind of company other companies want to be. Bev and Wayne Smith"

"Had them replace my air conditioning unit, they did a good job and completed the installation quickly. Everyone was very patient with my questions and additional requests. But Mark has fallen short on following through with providing me with requested warranty certificates or bill of sale, after asking twice. There is a fine line between exceptional and mediocre - and that line falls on completing paperwork and promise follow-through."

"They took pictures of the burned coils etc., and the next morning they were here exactly when they said they would be. They had a new system replaced and installed in 1/2 a day, no mess left, no incidents during or after the repair or in the last year. They even made a make shift door to replace the wall they took out. The air works "SO GOOD" I have to turn the air up because it gets so cold. Or is it down? Regardless, they did an Excellent AAA***** job. Thanks guys. Well worth the money spent."

"Jim was very helpful and personable to work with.  I had recently moved to the Huntsville area and was unable to connect my wireless printer.   There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer.  Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS.  He was able to get the wireless connection to work as well.  He took the computer on a Friday evening and returned it Sunday evening in prime condition. 
A few weeks later I  got an error message while reinstalling my accounting software so I called Jim.  He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable.  I will definitely use his services again.

FAQs for air conditioning projects in Mexia, 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.
