"I could not be happier with the service I received from Kyle and have already hired him for another project! After having my oil company tell me they could not fix my compressor and it would cost $12K to replace it, I went a year without AC in the main section of my house. Out of desperation because my mother was visiting, I reached out for a few more quotes. Kyle was able to fix the problem without having to replace the entire compressor for a fraction of the cost. In addition to that, I asked him to check the Freon levels on the other compressors, which he did and refilled. He was honest with me and did not need to fill one of them, which was great because it required a more expensive Freon. He could have taken advantage of me as a new homeowner like others companies have done, but he didn’t and gained a lifelong client in the process. If you need HVAC work done, give him a call!"

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.
