"Great company! I met them at a home show and had them come out and give a bid on taking out my old heater and replacing with a heat pump and air handler. Jeremy came out and gave a very thorough bid with several options on compressor/air handler combo. We ended up choosing a middle of the line solution that was very competitively priced in comparison with the other bids we got. What sold me was their attention to customer service and the ratings they received. This was not a cheap system and I wanted someone who would stand by their work and work with us to our satisfaction. I am very pleased. The installer crew showed up on time and went right to work. They found some wiring issues and fixed them as well at no change to bid. They spent a long day but did it all as planned. They took the time to do a walkthrough on the electronic air cleaner and on setting up the new thermostat (it even has weather forecasts on it!) and operation of the system. Again, very happy with that touch. I am also planning on a yearly maintenance contract that extends the warranty of the system if I continue to use them (which I will) for up to ten years. Janice in the front office kept me well informed throughout the process as well, even scheduling inspections. This is a great company that listens to the consumer and does what they say they will. I Highly recommend them to anyone!!"

"Honest, competitively priced, close attention to detail and great customer service. After careful analysis of what my needs were and within my price range, a Ductless Heat pump was installed. This system has reduced my heating bill over $100 a month. I love it! I highly recommend this company."

"Nate, Jason and the electricians that worked with them were fantastic! I couldn’t be happier with their service. They installed a new heat pump and central A/C for me, and were punctual, professional and efficient. They explained the work they were doing so that I understood what was going on, and even identified some potential issues that I hadn’t noticed. I’m glad I went with Hunt’s, and they’ll definitely be my first choice for HVAC moving forward."

"We had central AC added to our home 5 years ago. We decided to get an AC and furnace tune up before the summer. Matt, the technician from One Hour Heating and Air, was on time and polite. He pointed out that our furnace filter had not been changed since 2022. Big oversight by me. Matt explained how the air flows through the furnace and the direction the filter needs to be placed. I marked with a sharpie on the furnace an arrow so I would remember next time. Positive experience."

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.
