"They replaced my central air conditioning and hot water heater. Great process, good people. Very patient, answered all my questions (I was an engineer, so you know there were a lot of specific and obscure questions). Not the lowest price, but when it comes to making sure that the job was done correctly (and excellently) the first time, they were very well worth it!"

Small jobs welcome

Hello everyone I'm Nick, Im a 37 yr old with 20+ years of working with my hands on all sorts of jobs. From framing houses in my younger days to running small crews doing HVAC. I've also done full hard scapes both installing and repairing/ reviving along with your normal small home repairs. I'm very knowledgeable and take pride in my work. I have most tools to do any job but depending on the job I may have to rent or purchase that tool required to complete the job. I am goal oriented and focused at doing the job right the first time. I have a sharp eye for detail and am not a lipstick artist if you know what I mean. The job will be completed correctly. If you hire me you can be certain to be treated with respect and honesty throughout the process along with a fair cost for the job. \n\nThank you for the opportunity and I look forward to hearing from you.

"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 decided to add central air to our house. I called sure-temp as they installed our furnace 4 years ago. Based on my furnace experience, I expected a quote from a polite, professional person and that is exactly what I got. Interestingly enough, I mentioned to the estimator that I felt that Sure Temp was very reasonable with their products and pricing. He said quite bluntly that they were not necessarily the cheapest but that they worked hard to support everything that they sell. To be safe, I had 2 other companies do an assessment. While a month and a half later I have yet to hear from one company, the second was $200.00 more for a similarly featured competitive model. Add the 36 month interest free financing and I am happy. To be honest, the estimators from all 3 companies were professional in their work.
Ok. Back to sure temp. The quote came to me within 2 days. After doing my due diligence, I contacted Sure Temp to confirm, got approved and within a week the install was completed. Talk about fast! The installers arrived early and were pleasant and professional. They cleaned up after themselves very well.
From the initial call through completion, everyone I came into contact with at this firm was never anything but polite, friendly and professional. I would recommend them highly.

FAQs for air conditioning projects in Waterloo, 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.
