"While having our air ducts cleaned, mildew was discovered on the inside the supply plenum on our A/C unit in the attic (possibly from all the moisture Harvey dumped on us for days). Although the unit was only four years old, we decided it was best to replace it before it got worse. To hopefully avoid this type of problem in the future, we wanted to install some form of UV light in the plenum after it's replacement, but we were very concerned about the ozone that's released into the home's air from some of these types of lights. Matthew from Air Specialist listened and addressed all of our concerns about UV lights, and gave us information about each type on the market and which ones would address our concerns. After research, we decided on one of the Lennox UV lights and Matthew installed it for us. So far we've had no problems with this UV light, and we continue to be happy with Air Specialist's work."

"Over the past nine years I had fifteen AC vendors with fancy advertising fail to fix condensation in the cramped attic and unbalanced air flow in the house. I spent lots of money on small fixes and one large - a brand new HVAC. Still, trouble continued with the dripping water, mildew, and mold. Punbar's team came here on the recommendation of a home inspector and studied the problem with technical measurements like no one else ever did before. Their complete renovation and reinstallation solution seems to be working very fine after six weeks. Thanks Punbar."

"Felipe was recommended to us by a member of our church. Our air conditioner compressor and coil needed to be replaced. From the beginning, Felipe and his crew were very professional, always on time or early, extremely easy to contact, and genuine. Felipe asked my husband to walk with him and stand next to him during the inspection and repairs so that we would know exactly what was being done. His price was very fair. As a Houston mom of three babies, I could not be more grateful to have our air conditioner back and running! We could not recommend him enough. Thank you so much, Felipe!!!"

"Andres was amazing. My father had a stroke in January and our a/c unit stopped blowing cold air completely. I was concerned for his health and needed someone immediately. Not only did Andres come out in less than 2 hours, but he drove from Katy to Rosenberg to do so. He went through and made sure to thoroughly check what the issue was. He gave me several options and a maintenance plan that will save us a great deal of money. He made sure to listen and to provide the best plan of action possible. This is my first time using HomeAdvisor and couldn’t have had a better experience."

"Excellent service from the start to the end of the project (replacing house AC/furnace unit). Great pricing! Good-quality products! The owner (Jose) was very responsive, gave free quote with several options tailored to the local conditions, happy to listen and discuss various aspects of the project. He quickly responded to my additional questions and requests and even gave me some upgrades for free. The crew was professional and completed the work as scheduled, including some additional work (fixing disconnected duct, improving AC drainage, etc.) and cleaning. Definitely recommend this company."

FAQs for air conditioning projects in Katy, 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.
