"I’ve been an Alpine customer since 1975. Alpine is a remarkable example of a small business model (regardless of industry) that other businesses would be smart to emulate. It’s astounding, how they continue to flourish given accelerated market threats, market opportunities and government regulations. They also figured out how to stay more than relevant even with rapidly changing technologies, suppliers and price, along with the active consolidation of small companies by the behemoths (e.g. public utilities, big-box). Their secret sauce is their founding principles of authentic commitment to customer perceived value and continuing to grow/train their exceptional technical service folks. Congratulations on achieving and sustaining your founding vision. Well done! --------------------------My Alpine History------------------------------------------------ I moved to NJ in 1975 and began an immediate search for the best services providers (e.g. MDs, HVACs, Auto Mechanics). I have extremely high standards in terms of quality, price, customer focus and ethics. Furthermore, because of my professional background as a senior consultant for IBM, I am very detailed and fact oriented. All houses in my development had been built 15 years earlier with ducts for forced-air heating only. I brought 3 specialist contractors to evaluate installing AC using the existing ducts. Art Staloff (the owner of Alpine Refrigeration, founded 1972) was the only contractor whose assessment seemed credible and reasonably priced and then proved to be absolutely true. Over a 44 span, I’ve exclusively used Alpine for all my HVAC needs and most recently a whole-house generator. I’ve also taken advantage of their well-priced and high-value pre-season service agreements Paul Raskas East Brunswick, NJ"

Window a/c unit installations FAQs

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

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.
