"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.

"Working with James Martin and his staff at Air Advantage LLC has been an absolute pleasure. The work they did to my 1930's home is remarkable and was no easy feat. He designed and he and his staff completely installed a Heat Pump, all of the duct-work, venting, and return. The whole kit and kaboodle - I cannot be more thrilled with their work ethic, customer service, transparency, and the ability to take feedback. With my project they faced many challenges and rose to each of them without complaint. My crawlspace/hand-dug basement is particularly spider webbie and not an ideal space to spend several days. He was my advocate as a homeowner and offered the reassurance and guidance any homeowner should have. His "helpers," (as anyone knows, really the backbone) were kind, courteous, mannerly, and responsive - very warm individuals that convey trustworthiness as does James. James was very hands-on, fabricating all of of my custom duct work, and was communicative. His is also it seems a great boss - that is fantastic. I had a meltdown at 3:00 a.m. and James responded to an email before I could even wipe the sleep from my eyes. They were kind to my pets and tolerant - James saved my 15 year old dog's life, and his assistant was there in a flash during a totally freak incident. WOW! JUST WOW! I am a single woman with some background in the professional electrical industry and I can tell and will tell anyone, that this operation is a class act. I highly recommend them - I will be endeavoring in a large renovation project soon and will absolutely hire them for modifications and expansions. There are not enough positive adjectives to describe my experience with these guys. They were $4000 lower than one of the "Big Guys" in the Blue Ridge - and I know that my system is far superior, installed with care, and with honesty about what I did and did not need. Hire them! You will not regret it!"
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.
