"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."

Vent Heating & Cooling service is a family owned and operated company that has been servicing the La Grange Park, Illinois area for over 30 years. We offer comprehensive heating and cooling services to residential areas and are experts in our field. We have always been the preferred choice over our competitors. We can keep your family home at consistent comfortable temperatures at affordable prices. For quickest response please give us a call.

"This is our second year in our home and we realized last winter that our backroom addition had little-to-no heat flow and was frigid cold. Our goal was to make that room usable year-round. We bid with two other HVAC contractors and we pulled the trigger with Jim and his team. What put them apart was that they took their time assessing our home and situation, walked through all possible options, and clearly communicated those options. They evaluated and wanted to find the most feasible option for us, with efficiency and cost in mind. The other contractors came through and kind of already had their minds set on what heating system to use. Jim is also very personable, knowledgeable, and easy to communicate with. Jim and Carlton's proposal was the most cost effective overall - the unit/system itself and our personal ROI. It was gas as opposed to electric, the job was the least complex in terms of labor and construction, and it's functionality was worth the price."

TR Miller Heating, Cooling, Plumbing and Electrical has provided the Plainfield, IL area with excellent HVAC, plumbing and electrical services since 2008. Offering straightforward pricing, emergency services and the latest technology, they will help with all of your home service needs. Call today to schedule your appointment!

"TR Miller Heating, Cooling & Plumbing I think an obvious first step for the company is to be more upfront with pricing. By offering an upfront cost of $79 to assess a plumbing issue seems reasonable. To then have a minimal price that starts at $494 for something as simple as a 45 minute repair seems very unfair. It is similar to a bait and switch--reasonable to ridiculous. I was very specific in my needs--which was to connect two 1" water pipes 4 3/8" apart. I even forwarded a pic before anyone from TR Miller came out to the residence. The explanation from the manager was inadequate and false. Manager stated pricing was based on 50% going to the technician, 40% for overhead, and 10% profit. While I have already gone through the manager's exaggerated pay rate for the technician repair at roughly $250 per hour, Glassdoor site shows a technician hourly salary ranging from $20-$33 per hour. Even at an hourly rate of $50 per hour, a 40 hour per week technician would be at an annual salary of $100k per year-- which is probably closer to reality for pricing. With inflated non-factual pricing to start for labor and then factoring your overhead and profit off of an inflated labor rate, you literally are overinflating pricing by a large margin. Very unfair for a homeowner enticed to use your service which supposedly starts at $79. Will continue to be dissatisfied with my experience with TR Miller. You are a predatory company taking advantage of people. Based on my math, you would have still had great and more fair margins for a 45 minute job charging $250 for the job."

FAQs for window a/c unit installation projects in Carol Stream, 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.
