"Beware of Brian Hoffman, DBA “Premier Services”. I agree with all the negative reviews here - I had the same experience. He did a bathroom project for me October ‘24. He did a poor job, including an improperly installed toilet that was leaking under the floor. He agreed by text message to a $300 refund in Nov. ’24, but still hasn’t paid as of the end of July ’25, even after losing in Small Claims Court. He uses multiple addresses in various LI towns and won’t tell you his actual current address. The one listed on Angi is a street that does not even exist. Now he won’t respond to texts or phone calls."

"Very pleased with this company. Professional, timely. Our home, porch, shed, and stairwell are sparkling. The two workers were polite and efficient and when I questioned why my office window looked like the soap was not rinsed he advised that they rinsed it twice (2nd story) and offered to clean it again. It is now perfect. This is a difficult window for us to access."

FAQs for window a/c unit installation projects in Mastic, NY

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
