Types of Thermostats We Install in Carol Stream

Older thermostats don’t provide homeowners with the flexibility and energy savings they’ve come to expect. Smart thermostats, on the other hand, offer complete environmental control, even when you’re away. If you’re ready to upgrade, Gray's is here to help. Below are a few types of thermostats we install in the Bloomingdale and Carol Stream area:

Programmable Thermostats

These thermostats can be set to various temperatures throughout the day. If you work 9-to-5, it can raise the temperature of your home to limit AC use, accordingly. For sleeping, the heat can be set to automatically turn down to promote better, deeper rest. With their wider feature availability, these units have almost completely replaced setback thermostats.

Non-Programmable Thermostats

If you don’t want to deal with the hassle of programming your thermostat, we have a number of simpler options to choose from. These allow for simple button control while still providing the comfort you’ve come to expect.

Wi-Fi Thermostats

Wi-Fi thermostats can be synced up to your phone via your home’s Internet connection. This allows you to update your home’s temperature anywhere in the world while also enabling easy, intuitive programming. We have both Android- and Apple-compatible models available.

Smart Thermostats

Smart thermostats integrate with other home automation tools, like smart speakers, to take the hassle out of comfort. They can recognize your lifestyle patterns and adjust your home’s temperature to match. These units are best suited to tech-savvy households looking to cut energy costs.

Easy-to-See Thermostats

Easy-to-see thermostats are the best idea in thermostats and few people know about them! They work the same as a standard thermostat and are as easy to use. An easy-to-see thermostat has very large raised numbers that people with impaired vision can easily read. An audible click sounds at each degree mark as you adjust the temperature by turning the dial. An optional large clear dial cover is available to assist those who are hindered by arthritis.

Why Smart Homeowners Install Digital Thermostats

Modern thermostats offer a number of advantages over conventional ones. Here are a few reasons you might want to call for a quote on thermostat replacement:

This means more money in your pocket for things you like and enjoy. You can also reduce heating and AC while you’re away, conserving energy while on business trips or vacations.
  • Precision Control: The use of electronic controls allows modern thermostats to more precisely meet your temperature needs.

What to Check Before Calling for Thermostat Repair in Carol Stream

If your thermostat isn’t working right, you might be wondering what to do next. Before you give (630) 283-7981 a jingle and tell us,"My thermostat isn't working, what should I do?" Here are a few things you should look into:

  1. Have you set your thermostat correctly? You’d be surprised how often we show up to a home and the fix is just a simple change of the selector switch from ‘heat’ to ‘cool’. Verify that your desired temperature is set correctly and that your unit isn’t trying to heat your home in the middle of August.
  2. Are you having power issues? If the digits being displayed aren’t showing properly or the text is dim, it can be a sign your unit isn’t receiving adequate power. To see if this is the problem, try replacing the thermostat’s battery.
  3. Is there a mounting issue? On an older thermostat that isn’t digital, if the readings are faulty, check that the unit hasn’t come loose from the wall. Use a level to see if it’s crooked or out of place. Try tightening the anchoring screws if you spot a problem.
  4. Is your thermostat improperly placed? Your unit will struggle to get a proper reading if it’s placed next to heat or cold sources like a vent, stove, window, or register. Try removing the source of temperature fluctuation and seeing if readings improve. If so, you’ll want to call us to move it to a more optimal location. It is also important to have your thermostat located in a room that has an outside wall so it responds quicker to changes of the outdoor temperature.

If none of these things work, then it's time to call a Carol Stream HVAC contractor. A heating and cooling professional has the skills needed to quickly find and fix the problem.

Excellent experience with Gray's.

The team was professional, efficient, and easy to work with throughout the process. Highly recommend Gray's for anyone looking for fast, reliable, and fairly priced HVAC service.
S.M Suhail
Excellent Residential and Commercial Furnace and AC Service
I’ve had the pleasure of working with Gray's both personally and professionally. They’ve handled my regular furnace and AC maintenance for many years, always to my satisfaction. When it came time to replace my furnace, their expertise with our complex setup made it an easy decision to trust them with such a significant investment. Professionally, the company I work for also relies on Gray's to provide reliable and cost-efficient service to nearly 200 condo associations across the Chicagoland area. Their staff is friendly, knowledgeable, helpful, and patient — truly a pleasure to work with.
Jacqulin Goodlove-Schroeder
World-Class Furnace and Heat Pump Installation
My experience with Gray's was world class. From the initial estimate walk through in my home, to the installation of my new heat pump and furnace, the experience was pleasant the whole way through. The entire process with Gray's was efficient and effective, just like our new HVAC system. They've found the perfect combination of new school technology and old school relationship building. I feel like I'm in the right hands going forward!
Drew Doster
Friendly Late-Night HVAC Service
Gray's, thank you for sending Anthony to us. It was a late night emergency call. He was very friendly, courteous, knowledgeable and extremely professional. We will definitely keep your company in mind should we need any additional service. Thank you!
Hector R O
Respectful, Informative, and Fast AC Repair
We had Gray's come out to see why our AC unit wasn’t cooling correctly. They were able to come out right away, then figured out we had a small leak. We were given options by the tech that made me feel like I wasn’t being forced into a decision I didn’t want to make like I’ve felt from other companies. I wasn’t being talked into buying a whole new system, which was very important to me. Kirby was able to fix everything up that day and we had cold AC in under 3 hours. The office staff were easy to deal with. I also spoke to the owner, Dan, when he followed up with me and he was super friendly and professional.
Jonelle Salinas
Efficient AC Repair and Helpful Maintenance Tips
I recently had Sergio and Eric come over to update our AC unit for the summer, and I couldn't be more pleased with their service. From the moment they arrived, their professionalism was evident. They thoroughly inspected our unit and quickly diagnosed the issue causing it to shut off unexpectedly. Not only did they fix the problem efficiently, but they also provided us with excellent recommendations to prevent future issues. Their expertise and friendly demeanor made the entire experience seamless. I highly recommend Sergio and Eric for anyone in need of AC maintenance or repairs.
Marcus Howard
Effective Heat Exchanger Cleaning Fixed Furnace Fast in Sub-Zero Weather
We were in desperate need of help. Our furnace had stopped working and the sub-freezing temps were expected to drop to zero. Panic was setting in. But, Gray's was able to send their skilled technician, Sergio, who arrived almost two hours ahead of schedule. Sergio, diligently and expertly examined the furnace. Eventually, he diagnosed that a very dirty heat exchanger was causing poor airflow causing the system to shut down. He then spent a considerable amount of time in a very cramped space cleaning the suspect part. Eventually, he emerged, dirt smudged on his face with a bag filled with dirt. The system restarted and we are not in danger of suffering from hypothermia.
