"The fix was straightforward, had to replace the AC blower unit motor. Garmer handled the task expertly and with great customer service, despite them discovering an unusual screw installation from the prior owner which caused the housing removal to take a bit longer than they initially anticipated and first quoted (which, if you've owned a home, tends to happen somewhat often as equipment of this magnitude usually can be more complex than they first look). The only thing I would suggest is that they re-address their pricing. This job ended up costing around $1,200 to change a blower motor where the part itself probably was no more than a few hundred (final bill was delivered upon completion) - was estimating maximum $1,000 given their guidance throughout the job. At a certain point, it may make sense to give the customer a flat project fee as opposed to remain on hourly labor billing as the crew is trying to re-assess to avoid customer sticker shock and alienating future work. I respect the crew, the work they did, and value their labor, but believe the pricing is high. I would like to stress that I would recommend and would consider using them again simply because of their expertise, customer service, and responsiveness as they do great work, but would be more critical of the price ahead of time."

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.
