"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

"Joe responded to my online "request for quote" within an hour of me posting it. He offered to come the next morning and arrived exactly on time. He assessed within 10 minutes that a capacitor in one of our units had blown, probably due to a line surge from a lightning storm, and had a replacement capacitor in his truck. The capacitor was replaced and the repair completed in 30 minutes. He then a quick review of our entire system to assess its overall health. My experience with Joe was so good that I have asked him to send me a service contract to maintain my AC system going forward."

Met Anthony at the exact time he said he would be there. Friendly and personable. Not only did he do the service but he also took time to educate me. I have 2 AC units and only had him do the one with the issue. I am now calling him again as the other unit needs some work. I will update this afterwards but am very confidant that it will go as good as the first time.

my second ac unit stopped working and after a good experience with APV Mechanical (Anthony) I called him for this problem.
Anthony arrived and all the signs indicated a system low on freon. Anthony filled the system and when we went to test it, the pressure shot through the roof. He the spent 2 hours trying to figure out what was up. So 3 hours after he arrived of which 2 hours Anthony went through my system and tested every component it became clear that the blower was not coming on and that was causing the freeze up we had been experiencing. A Petro mechanic had been there the day before and worked on the electrical relay switch that is causing the problem. Thanks to Anthony's patience and knowledge ( He really knows his craft) I now have Petro coming back to put the relay switch back the way it was. I will use and recommend APV and Anthony to my friends and family."

"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.

They are the biggest on Long Island. It is free service every year. They clean if necessary or whatever they do. It did not need a cleaning this year. It is my second year and they did it last year. They are all over the island. I have one my research and they are in-line and a little bit better than others. They have been good to me so far and I sticking with them as long as it works that way. I have not had any bad experiences. They did bill me for a service call which was not billable, it was included. They quickly corrected it when they realized it, so no problem. I am under contract with them.

"William Sallee gave me a very competitive quote for a 4-ton AC high efficiency 16 seer unit. My attic is very small and the two installers had very little working room to put the air handler in, but amazingly they did it and so far the system is working great. They worked very clean, were nice to work with and answered all my questions."

FAQs for window a/c unit service or relocation projects in East Hampton, 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.
