"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."

"Chris was great. He gave an estimated arrival time and kept me posted about when he would arrive. Once he arrived, he was very professional and respectful of my home; he didn't even mind my nosy cat. He gave me an assessment of possible repairs needed on my portable AC, gave me an estimate for possible costs and provided an invoice on the spot. He made the whole process very easy, and I appreciate the time he took to explain everything. I would definitely hire DG HVAC & Home Services again for my appliance repair."

"Anthony and his crew were awesome! Always available, punctual and professional. Nice clean work and fast. They're pricing was better than most and am very happy with the service. They installed a ductless ac unit with 2 heads in my basement. From start to finish they were great. I would recommend them to anyone."

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