"The techs were professional, friendly and knowledgeable. My boiler needed some work and Sync Mechanical was a God send. They kept my home nice and toasty. I've wanted central air installed in my home for quite sometime, and hiring Sync Mechanical was a no brainer. The process was explained to me in full detail and they answered every question I had. I'd recommend Sync Mechanical to anyone. Great work!"

"Very friendly, knowledgeable and professional salesperson. Price was right in comparison to other esitimates. Took time to explain the tax implications of the new, more efficient heating and AC equipment. Explained the available rebates from Central Hudson and from Carrier. Salesperson forgot, however, to mention to the service men that the humidifier we ordered had not arrived by the day they were installing the units. Salesperson admitted that he forgot to tell them. Media filter was not installed during the first installation visit."

"Sometimes you just get lucky. We got super lucky when we hired D. Rohde to fix our A/C. Our technician Mike A. showed up with a helper/trainee, explained the estimate fees and then went to work. In less than 10 minutes he was able to identify the defective part, return to the truck for a new replacement part, and then install the new item. In under 30 minutes our main central A/C was back up and running. The second (upstairs) central air unit took another 10 minutes to diagnose and then about 40 minutes of grueling work in a super-hot attic to drain out the overflow tray, cut, blow-out the drain line, and repair the drain. Once drained, the unit is again working perfectly. It is great when a technician shows up and really is an expert. Mike A. is such an expert and also extremely friendly. Brandon, the assistant/trainee was also great and someday will make a great technician using all the knowledge learned from Mike's expert tutelage. I will recommend these guys to everyone I meet."

Now, everything has been corrected and works great. The new boiler is smaller and quieter. Very professional and completely trustworthy."

FAQs for air conditioning projects in Marlboro, 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.
