"The technician was very professional and respectful of my home by removing and/or covering his shoes as needed. He kept me informed about his progress and issues he found as he continued his work. The furnace is very old, so he conducted research, determined the problem, got the needed parts and completed the job for a reasonable cost. I would definitely use his services again. 5 stars!"

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."

"B&K were very reasonable on price for a pair of small projects while still providing a high quality of work. While their workers were here they did a great job of communicating and verifying exactly how I wanted things done rather than just guessing or doing the work the easiest way they could. I'll be calling again next time I need something similar done."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
