"Courteous, Professional, and Knowledgeable HVAC Installer - Needed to replace a 25+ year old HVAC system in the coldest months of the year and SwiftPro was the right choice. I live in a condo with a tricky indoor/outdoor HVAC set-up. Tyler worked with me to ensure I had the right system that 'fit' in the area left after removing the old system. Workers were completely professional and knowledgeable during installation and dare I say - courteous. Installation was supposed to be same-day, but one part was unavailable at the time. Tyler and his staff hunted across the local area for the part and even sent an employee out to buy a space heater to spare me from the below-20 degree night. Part came in next day and installation was complete. Very satisfied with the outcome of the project."

"Ruben and the team did such a great job on the first project (2-3yrs ago) that I asked them to come back and finish my condo's water heater closet, which showed wear and tear from past water damage. They did a fantastic job in repairing the closet and adjacent living room's dry walls that it looked seamless to the rest of the unit. The team was always conscious of keeping the work area clean as they closed the area off with tarp and placed drop cloths down. I greatly appreciate the amount of high-quality work done in a short time span, especially when asked within two weeks of the project starting. I've recommended the team to my family and friends if they ever need a job done right by a team who is professional, courteous, and knowledgeable."

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.
