"Professional, knowledgable, and efficient service. Recommend A-Plus Air Conditioning & Home Solutions. Our new A/C was making a loud rattling/rumbling noise when we started it up this year, like a washing machine out of balance. I found A-Plus Air Conditioning based on reviews here and on the Lennox website. I called A-Plus and one other company on Thursday morning. The competitor was not able to fit me in the schedule until Monday. David at A-Plus called back within an hour and scheduled me for Friday morning. We had a mixup on the telephone number, but when I called Friday as my initial window was ending, David called back and placed me in the queue within an hour. Jeremy arrived with a smile and pleasant demeanor. He opened up the air handler and quickly found the cause of the rattling. A small plastic wrapper was the culprit. Jeremy tested the system with just the fan and then the A/C and the noise was gone. No muss, no fuss. Quality work! Will call A-Plus for future preventative maintenance. Thank you for your prompt help!"

"Well, I had 2 different contractors come out and tell me I need new units because they were undersize and the duct work was the wrong size. My house is a year and a half old. Petrocelli Services came out and added return air ducts and individual thermostats. It’s was an 1/8 of the price and it worked. They knew what I had been quoted. If they had said the same thing as the other two contractors, I would have been ripped off for several thousand dollars. I’ll never call anyone else for my AC needs."

"Excellent. We couldn't be happier with the work Legacy did. The people (Raymond and George) were punctual, friendly and very considerate of our home. They correctly resized and replaced our air ducts and installed a Reme Halo. I inspected the work they did and was very impressed with their work. Air circulation in the house is 100% better and stronger, a great improvement."

FAQs for air conditioning projects in San Marcos, 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.
