"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.

"Jim was very helpful and personable to work with.  I had recently moved to the Huntsville area and was unable to connect my wireless printer.   There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer.  Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS.  He was able to get the wireless connection to work as well.  He took the computer on a Friday evening and returned it Sunday evening in prime condition. 
A few weeks later I  got an error message while reinstalling my accounting software so I called Jim.  He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable.  I will definitely use his services again.

"During the massive December 2022 blizzard in Western New York, my house lost power for three consecutive days. I'd just switched to an all electric HVAC system weeks before, and none of it was connected to the small electrical panel that my gas generator could power. We were facing no heat, in a blizzard, for three days. I called Connor who, despite the weather conditions, came out to the house that evening. He opened my generator panel and rewired it so it would get heat to my kids' rooms. Without asking, he then found a great price on a Generac whole house generator and passed the information along to me. Long story short, I hired Enchanted Mountain to purchase and install the generator. They did that and more. My family now has no worries when the next blizzard hits. The care, knowledge, and attention to detail that go into Enchanted Mountain work are unmatched. I've since hired them for everything from roof repairs to insulation and weatherization jobs. They can do it all, and you won't find a nicer, more helpful and caring crew anywhere in the region. Hire them once, and, like me, you'll plan to hire them for life."

FAQs for air conditioning projects in Jamestown, 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.
