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."

"We have a very old furnace and AC unit and had been told after a maintenance appointment that we needed to replace the furnace. We had a few companies out to give us quotes and Ryan was the only one who suggested something other than simply replacing the units with high end, expensive units to get the cooling and heating that we wanted. He came out and did vent work to improve air flow and installed cold air returns in bedrooms that did not have them and was honest about the fact that our units did not need to be replaced yet. It was more a venting issue. After having him do the work, Our bedrooms are heating evenly and we are seeing all the results we wanted without having to replace a furnace that is still working. We will definitely reach back out to him when it comes time to replace the units! Very impressed with his honesty and willingness to investigate the problem instead of just sell us new equipment."

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.
