"We recently moved into a new home and our air conditioning stopped working. The previous owners had left us a list of subcontractors they have used in the past and Select a/c was on the list. We looked them up on Angie's list and gave them a call. They were able to come out the same day and fix the problem. Oscar was our technician and he was friendly, professional and did a great job! He worked very quickly! Before entering the house he offered to cover his shoes to protect our carpet. He was the first repairman in all of my years of owning a home who has offered to do this. I was so impressed! 
Our unit is 16 years old and I have very basic knowledge of how it works. Someone could have easily walked in and told me we needed a new unit and I wouldn't have known any better. 
It is refreshing to do business with such an honest company. When this unit wears out, we will be giving them a call. 
I have programmed their number into my phone and will be referring them to all of my friends and family.

"AirCo has done work for me the last 2 years. Always done good work, and appear to be honest with their quotes. I will certainly hire them again! I paid for annual service, once in the spring, again in the fall. Last winter, they did my air duct cleaning."

"Just when I thought I had already received a train of perfection HVAC services from Rescue Air Heating Cooling (and Plumbing), yes they raised the bar even higher. Today, repair expert, consultant, and general impresario Mr. Roman Arnold diagnosed, repaired, and rescued my older but wiser and otherwise excellent HVAC system from a state of non-function and he did this in only a few minutes, getting right to the heart of the matter fast. This did not surprise me only because my experiences with TEAM Rescue Air consistently demonstrated highest technical expertise, experience, sound practical judgement, kindness, consideration, listening skill sets, and representing clientâ s best interests. Thank you so very much Rescue Air for sending Mr. Roman Arnold for todayâ s â Rescue.â He is so experienced and expert, it is like he invented air conditioning. It was a good thing for me when I selected my new HVAC company that I landed at Rescue Air Heating and Cooling. I am a client/customer situated in North Dallas."

"Our 15 year old air conditioning system gave out and so we began to gather quotes. We requested several quotes from home advisor. Prime ac was the only company that showed up on time, performed a full evaluation and had the quotes ready same day. Install was done the next day and everything went great. Thank you for the wonderful experience and treating us like valued customers."

"Air conditioning stopped working and I went to a couple of neighbors here and both of them have used this company before, so I called them and they came to check and he said that the compressor was not working and they gave us a couple of options to proceed, he thought that he could find another compressor but probably will not be new since next year companies will not sell these units anymore because of the cooling system so then he suggested to replace the entire system. The end result was amazing, this ac unit does not make a sound at all. They actually helped the neighbor and it was free of charge, he asked me to listen to that ac unit and he explained what was wrong with it and he suggested me to give them advice so they could fix their ac system too."

FAQs for air conditioning projects in Denton, 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.
