"Ali's, (the owner) men showed up when they said they would. This was my daughter's condo. I got there a half hour before the men came. I found that my daughter didn't take the cover off the compressor. I called Ali to tell him what I found. He said his men were 5 minutes away and let them look at it. If that is all it is he would wave the service charge. After checking out the unit thoroughly they determined that the cover was the problem. The air was blowing cold. As Ali promised there was no service charge. It is refreshing to do business with a man of integrity. Not only will I call him for my daughter's unit but he gained a customer in me. His reviews are outstanding and now I know why."

"Anthony and his crew did a great job in providing and installing the exact system that I had requested.  
They were thorough, professional and very neat and very easy to work with.  The installation was completed in one day.
The pricing was more than fair.  I couldn't be happier with the new A/C system.  I highly recommend APV to anyone in need of a new central A/C system.

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"When the unit was returned and the timer no longer worked, Mike's A/C replaced the part with a fully functioning used one
and did not charge for it. I could not have asked for a better response or better service.

"Appointment next week but I've been a customer since 1983 and have never had a bad experience. They are a top notch co. They might not be the cheapest but they're truly worth it. My experience has been in the heating category so can't comment on their other services."

FAQs for window a/c unit service or relocation projects in Greenport, NY

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
