We are a full service Cooling, Heating & Electrical company. We employ Nate Certified Technicians, EPA CertifiedTechnicians. Our Home improvement License # is 19HC00144800. We also are a Lead Certified Contractor. Our Electrical Division License # is 11850B. Award winning.

"Ever since Bloomfield Cooling, Heating & Electric replaced a 5-year-old furnace that had been improperly installed by another contractor, we have relied on this North Jersey HVAC contractor for all our heating & cooling maintenance needs. Not only is the team responsive, polite, and professional, they have a great understanding of the latest HVAC technology and always recommend the best equipment. I recently had the company replace my downstairs HVAC system under the Carrier Cool Cash and PSEG Instant Rebates programs. The work was done efficiently, cleanly, and I am enjoying greater energy efficiency in my home. Next year I will have them replace my upstairs system under the same program. I cannot recommend Bloomfield Cooling, Heating & Electric enough."

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.
