Upgrade Your Comfort With a Smart Thermostat
A smart thermostat does more than adjust the temperature. It learns your schedule, connects to your phone, and helps your HVAC system run more efficiently without you having to think about it. If you are still using a manual or basic programmable thermostat, a smart thermostat upgrade is one of the easiest ways to improve comfort and lower your energy bills.
Girdner Heat and Air provides smart thermostat installation, configuration, and repair for homeowners across Eastern Oklahoma and Northwest Arkansas. We work with all major smart thermostat brands, including Google Nest, ecobee, Honeywell Home, and Carrier Cor. Proper installation and setup are critical because a smart thermostat that is not wired correctly or configured for your system type will not perform the way it should. According to ENERGY STAR, a properly installed and used smart thermostat can save homeowners approximately 8% on heating and cooling bills annually.
Smart Thermostat Options We Install
Different households have different needs. Here are the most common smart thermostat types we install and what they are best suited for.
- Learning Thermostats (Nest, ecobee)
Learning thermostats study your daily patterns and automatically adjust the temperature based on when you are home, away, or sleeping. They also use sensors to detect occupancy and adjust room by room. These are ideal for families with consistent routines who want a hands-off experience. Nest and ecobee both include remote sensors that help manage hot and cold spots throughout the house.
- Wi-Fi Programmable Thermostats (Honeywell Home, Carrier)
Wi-Fi programmable thermostats let you set schedules and make changes from your phone without the learning features. They are a great option if you prefer to set your own schedule and want remote access without the automated adjustments. These are compatible with most HVAC systems and are often the most straightforward upgrade from a basic programmable thermostat.
- Zoning Thermostats
If your home has a zoned HVAC system with multiple zones controlled by dampers, you need a thermostat designed for zoning. We install and configure zoning thermostats that communicate with your damper controls to maintain different temperatures in different areas of your home, reducing energy waste in rooms that are not in use.
Why Choose Girdner Heat and Air for Smart Thermostat Installation?
Installing a smart thermostat is more than swapping one device for another on the wall. Your thermostat communicates with your HVAC system through specific wiring, and not every thermostat is compatible with every system. Our technicians verify compatibility, handle the wiring, configure the device for your system type, and test everything before we leave.
- Certified installation for Nest, ecobee, Honeywell, and other leading brands
- Compatibility check with your existing HVAC system before installation
- Licensed and insured technicians with EPA certification
- Over 205 five-star Google reviews
- Free smart thermostat included with qualifying full system installs
We also help you connect your new thermostat to your Wi-Fi network, set up the companion app on your phone, and walk you through the features so you know how to use it from day one. If your home has an older system with limited wiring (like a system without a C-wire), we can add the necessary wiring or recommend a compatible thermostat that works with your setup.
Flexible Financing Options
If your smart thermostat installation is part of a larger HVAC upgrade, we make the full project affordable. We partner with FTL Finance and Wisetack to offer payment plans starting at $118 a month with approved credit. Wisetack also offers 0% interest rate options on qualifying purchases. We also include a free smart thermostat with every qualifying full system installation.

Whitney M. Warrior-Deerinwater
Had a great experience, especially the consultation! The information was as they presented, no hidden extras, it was a successful home project and the boys were so great to talk to and ask questions. All were knowledgeable and all worked efficiently. They also seemed to enjoy their work and how they happily carried one with each other. They needed to take more of the snacks but they were such a great representative of Girdners to have on our home projects! Highly recommended. Owner is also great to work with. Looking forward to working with the company again!!

They gave us an excellent deal and were really helpful when replacing our whole heating and air system! A big thanks to Joe, Wyatt and Garrett; they did an amazing job and worked an extra long day trying to get our AC working for us!
Definitely a great job and highly recommend them!
Deborah White
We had our HVAC system replaced in August 2024, and the experience was excellent from start to finish. The team completed the installation in a very timely manner and has been a pleasure to work with ever since. The system has worked perfectly, and anytime we’ve had a question, they’ve responded quickly and professionally. We are very, very happy with both the product and the service—highly recommend!

Frequently Asked Questions
About Smart Thermostats
Will a smart thermostat work with my current HVAC system?
Most smart thermostats are compatible with standard central air, heat pump, and furnace systems. However, some older systems, multi-stage systems, or systems without a common wire (C-wire) may require additional wiring or a specific thermostat model. We check compatibility before installation so there are no surprises.
How much can I save with a smart thermostat?
ENERGY STAR estimates that a properly installed smart thermostat can save approximately 8% on annual heating and cooling costs. The actual savings depend on your home’s insulation, system efficiency, and how you use the thermostat. Most homeowners see the investment pay for itself within one to two years through lower energy bills.
Do you repair smart thermostats?
Yes. If your smart thermostat is not responding, losing its Wi-Fi connection, reading the wrong temperature, or not communicating with your HVAC system, we can diagnose and fix the issue. Common problems include wiring issues, firmware conflicts, and sensor placement.
Can I keep my smart thermostat if I get a new HVAC system?
In most cases, yes. If your current smart thermostat is compatible with the new system, we can reuse it. If you are getting a full system installation from us, we also include a free smart thermostat as part of our current promotion, so you may want to upgrade.
Do you set up the app and walk me through how it works?
Yes. We do not just install the hardware and leave. We connect your thermostat to your Wi-Fi, help you download and set up the companion app, and walk you through the key features so you are comfortable using it from day one.
