"My wife and I were throughly impressed with the professionalism of the company and their installation crew. They were meticulous in their work practices and went out of their way to keep us informed of the status of our air conditioning project from planning to completion. It was truly a pleasure dealing with such an honest and ethical HVAC contractor. Michael Santana, along with his talented team of Enrique and Raul more than exceeded our expectations with their outstanding work and customer service. We solicited quotes from numerous contractors and Aire Care Heating and Air Conditioning hands down provided the best cost and installation proposal. If you are looking to replace your HVAC system, I highly recommend that you contact them."

"The technician - Kade - was very nice and we could tell he was having a really bad day. It would have been nice to know all costs upfront. Called later and complained to the receptionist/dispatcher who was also really nice. She gave me the owners phone number. Spoke to him. He was also very nice. Told me to send him a picture of my shower fixture and he could tell me the brand name and even walk me through replacing it. Photo and phone message sent later,..... no response. Thank God for YouTube. Watched a video and replaced it myself!"

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

"My ac wasnâ t working anymore, Tommy came out and was able to find several issues with the unit. He quoted me on a new ac and coil, after comparing prices with other companies I called him right away. Tommy and his crew replaced the ac and coil that same week. They were very courteous and respectful of my home. I highly recommend Tommy for your hvac needs."

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.
