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."

Handyman doing light plumbing, electrical, moving, assembly, and general home repair. No remodeling or construction. I've been doing many types of repairs for over 30 years. Prompt response and on time to job sites.

"Mike has been an excellent friend and worker for me. I'm so thankful to have found him to take charge of returning a rental house into a prospective home to list on the market. He does great work, responds and communicates well. He's surprised me on a couple of occasions by taking care of some items I thought would require many more dollars to hire a contractor. I didn't mention I live 2,000 miles away from the rental, so it's been a godsend to have Mike onboard. Great guy, does great work."

Heating and Air Conditioning questions, answered by experts

You should have your HVAC serviced at least once per year. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between $100 and $550 for HVAC maintenance, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services.

There are a few factors to consider if you’re deciding between repairing and replacing your air conditioner. It’s probably worth fixing the AC unit if it’s less than 10 years old, you’re dealing with a one-off issue, and your warranty or maintenance plan will cover the repairs. On the other hand, if your air conditioner is dated, inefficient, out of warranty, and experiencing multiple problems, consider replacing it.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
