"All of a suddenly we were in need of Central Air Conditioning replacement. I reached out to Angie/Home advisor for contractors serving my area and was given 4 contractors. All of them were very polite and knowledge but only one really stand out. David Coates from Hudson Valley Air Control was a pleasure to deal with; he is professional, knowledgeable, and courteous and gave a fair price for the work to be done. Unlike the other contractors, he didnâ t try to sell me anything that I didnâ t need. I checked his reviews and they were all excellent, so, I decided to go with him. I am so glad I did. He was punctual, did excellent job, installed top notch equipment (w/10 years warranty from manufacturer), cleaned up after himself (the only sign that he was here is a brand new Condenser unit on the side of the house) and all for a fair price. The contractor that gave me the next price up from him reached out to me to follow-up on his estimate, and told me that he would be curious to find out what the contractor was not giving me in order to give me such a low price, and my answer is this: what he didnâ t gave me was a RIDE TO THE CLEANERS. I highly recommend Hudson Valley Air Control, and I will definitely use this company again, when/if their services are needed in the future."

"Hands down recommend Sync Mechanical! They were able to repair my central air unit when 3 other companies told me the only option was to replace the entire system. They showed up time and were affordable. Saved me at least $3,000 by repairing the unit. I will definitely use them for all my heating and cooling needs. Thank you guys so much!"

"Hard to say since I need to see how the a/c performs over time but seemed to explain and fix my overflowing pan that shut down my system. Keith had to snake out the sediment to allow the pan to drain. Good, prompt service. Keith was a good guy!"

"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."

Customers say: Quick response

"The service person was courteous and knowledgeable. WE DID NOT EXPECT TO PAY $127.00 FOR THE ESTIMATE at the end of the visit!! Then he offered us a â planâ ( no pressure) for total service with Electrician for several hundred dollar . It included to charge for estimates. Seriously!! We had wanted to go with local company but no thanks!! In addition, he didnâ t mention ceiling issues with steam in bathroom nor mold or venting. VERY Disappointing!! Rip-off!! I politely wrote to them and never heard back.!"

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.
