"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"We have used Sure-Temp over the years from 2007 through 2011. They have done lighting upgrades to installing new ductless- split Air Conditioning systems to repairing our Carrier systems. They have always tried to make the most energy Efficient choices and have led us in good directions each time we have used them. We have spent over $40,000 with them for work over the years.
There was some warranty work to do on the ductless-split systems and it was handled well by Sure-Temp.
We will continue to use them in the future."

"Murphy's Law said that as soon as I stacked the boxes of my wife's old but favorite art books, something would happen. I even asked her if we ever had more than a standing inch of water in the basement. That night, a discovered a growing puddle around the water heater, that was running down the side of the tank from a pool at the top. I called a local plumber who we had used before (and even texted photos of the water heater to them), but after two days of no call back even though I left a second message, I called Green Air Solutions. Jeff called me back immediately, and despite that it was dinner time, and I told him it wasn't a dire emergency), he was over at my house within a half hour. What I liked best was that he took time to figure out the problem and explain it to me. The previous owners had put in two water heaters (I assumed to fill the large jacuzzi upstairs), but only one was being used. Fortunately, we had a backup already in place, but it made for interesting puzzle. Jeff seemed to enjoy figuring it out, worked fast, and had it removed and the other one up and running in an hour. When I first realized that the heater was shot, I expected an expensive job. It was not. That's how a service vendor builds trust and clients. The other plumbing company? They still haven't called me back. Thanks Jeff!"

FAQs for air conditioning projects in Oneonta, NY

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.
