"We moved into our house about 3 years ago and the first thing we wanted to was get a heat pump. They were very friendly. When we were about to have the heat pump installed our sewer pipes backed up we ended up having to replace our sewer pipes and the heat pump at the same time. right after we bought the house. Both companies worked with us on some payment options without financing.
about a year later we wanted to get our heat pump removed from our basement. So we asked them to come out again to see how much it would cost to have it removed. It was the same guy who came out the first time. He told us that to remove it he would have to charge us about $3800. He told us not to have them do it because he didn't want to charge us that much. He recommended an alternative for us which worked out and save us a lot of money. I will always use New River Heating and Air for my projects because I know that they will do what's best for me not just their bottom line.

"James is by far the best HVAC guy around! We are super pleased with his fast response and great work. We felt we were in good hands right from the beginning! He was very respectful of the house, extremely knowledgeable, explained things thoroughly, and the cost compared to others that I have hired in the past was very reasonable. I appreciate that he isn’t one of those guys who will immediately try and get you to get a new unit; he will track down and fix problems that others have found difficult, which is the case for us. Thanks for saving us $4500 dollars James! Without a doubt we would recommend Air Advantage to all our friends and family! You won’t need a second opinion if you call Air Advantage first! Trust me, You won’t be disappointed."

"These folks went out of their way to get air conditioning in my home , They were very professional and thorough. I would not hesitate to hire them again."
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.
