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."

Energy Efficiency Auditing questions, answered by experts

Yes, advising on models that save electricity and reduce utility bills.

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
