ONE CALL CAN SOLVE ALL YOUR HOUSE PROBLEMS Professional Handyman Services, Kitchen & Bath Remodeling, Plumbing, Electrical, Carpentry, Tiling, Flooring Insured Bonded Guaranteed LIVE PHONE HELP Mon-Fri 8-5 email chat after hours... Chicago Home Repair License #2209943

"Gary did a thorough of replacing my dead sump pump and removing the back-up sump pump, also dead. He had to reconfigure the discharge pipe since there is no longer the back-up. There was an added charge of $20 for the additional parts, but no added charge for the labor involved. He even examined the third sump pump in the well at the other end of the basement. He pointed out that one was dead too. After watching him replace the main sump pump one, I feel confident enough to replace this one by myself. I would have given Handyman Pros a excellent rating for professionalism, but they did not inform Gary of the amount of water collected near the sump pump. Boots were necessary, but he only had gym shoes. I laid some spare boards that were available to keep his feet dry. Beware: Handyman Pros does not provide sump pumps. They only install what you secure on your own."

For more than 50 years Cahill has provided customers with quality heating, cooling, electric, plumbing and sewer services.

"I had some backup into the basement, they came to rod it out and told me I needed to check the line going to the street and they could come back for a video check. Well they said they came back and took the video and I needed some expensive work to clear the line. I called to ask them for the video, they said that they'd have someone call me back. They called me back and said that there was no video, their worker didn't put in a USB drive and besides they said I didn't ask for one. What did they expect I was asking for??? I said I expected and wanted a video, how do I know they even really performed the work. They said they would call me back. THEY DIDN'T. I called them back, they again said they'd call me. Again no call. The last time they told me, the owner was on another call but would definitely call me back. One week later NO CALLBACK. I firmly believe they didn't do a video, charged me for one and took me for a sucker. I will NEVER use this company again. I think they are crooks. P.S. Ever since they rodded the drain one of my toilets started have trouble flushing. I won't doubt they messed it up so they could come back again for more money. DO NOT USE. P.P.S. I wonder if they will contact me on this posting, I doubt it."

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

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.
