"I might be getting tricked by this place and they are playing an elaborate prank on me. I am a VIP member of their service, so quarterly I get some free services done. Been with them for more than 5 years. It all starts with a technician doing a routine service on my furnace. The say the drip plate needs replacing. Ok, so they say they will order the parts. Months go by, I hear nothing. I email asking to do the work. Again nothing. I move on. Fast forward to new quarterly service. New tech says "oh no the drip plate doesn't need service, you need a deep clean." Ok $500 later I have a clean furnace. Summer comes around. Record heat. The furnace makes a jet engine noise, super loud! The fan in the furnace is obviously wrong. I make an appointment. Wait around all day. They call, "Oh sorry we can't actually make it today." Great, ok, well then come tomorrow. They do. They say that some belt was off or something. They fix it, under warranty of course, so no cost to me. But still Two weeks go by, now its RECORD heat mid-June 2022. We start to hear a GRINDING like a jack hammer from the furnace. We turn off the AC. So we have no AC mid-summer. They come by. The tech says another screw was loose and caused the blower wheel to grind and get stuck, thus blowing the blower motor. Ok...so they have to order the parts on Friday. "They'll be in early next week." Monday....Tuesday....Wednesday....oh the parts are in! Yay!! Appointment gets booked for the morning. I stay home from work......annnnd they come at 5:30 pm. Great. Two techs this time. They come by look around for a while, take things apart. Then they ask me, who came and fixed it last time, what did he look like. So now I am trying to describe a 20-something guy with a star wars tattoo that was in my 100 degree house last Friday. Long story short, the tech says that t he first tech did not say the motor was blown! I said "well I kind of remember him saying that." So new-tech looks up the notes. He reads his ipad and lo and behold, the first tech DID say the motor was blown, but new-tech FORGOT TO GRAB THE PART FROM THE OFFICE. He apologizes, says he'll get me on the schedule for tomorrow. Great. Ok. I get a call from their office saying "Your on for tomorrow." Cool. I take ANOTHER day off work. I call 8 am the next day to ask where I am in the schedule so I can, ya know, do things. I AM NOT ON THE SCHEDULE!! Well now this is getting a little irritating. So I kind of yell at them. They say ok, we will get you on the schedule for today. They call and let me know that the tech will be there between 10 - 11 am today. I am not hopeful."

FAQs for window a/c unit installation projects in Crystal Lake, IL

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.
