Signs It’s Time to Replace Your Thermostat

A thermostat does not have to stop working completely before it starts affecting your comfort. If it is reading temperatures incorrectly, causing your system to cycle at the wrong times, or no longer giving you the control you want, replacement may be the right solution.

  • Temperatures Don’t Match the Setting: If your home feels warmer or cooler than the thermostat display shows, the thermostat may not be sensing indoor temperatures accurately.
  • Heating or Cooling Runs Longer Than It Should: A faulty thermostat can cause your HVAC system to run too long, shut off too soon, or cycle more often than necessary.
  • Your Thermostat Is Outdated: Older manual thermostats do not offer the scheduling, efficiency, and convenience available with modern programmable and smart models.
  • The Display or Controls Are Unresponsive: If the screen is blank, buttons do not respond, or settings do not save correctly, the thermostat may need to be replaced.
  • Rooms Feel Uneven or Uncomfortable: Thermostat issues can contribute to temperature swings, especially if the device is installed in a poor location or no longer communicates properly with the system.
  • You Want Better Energy Control: Smart thermostats make it easier to adjust temperatures, create schedules, monitor usage, and manage comfort from your phone.

Thermostat Replacement

If your current thermostat is outdated, inaccurate, or no longer functioning properly, we’ll recommend a replacement that works with your HVAC equipment and install it correctly.

Hybrid heat systems require thermostats designed to switch efficiently between a heat pump and furnace. We install compatible controls that help your system maximize comfort and energy efficiency throughout Minnesota’s changing seasons.

For homes with zoning systems, we install thermostats that allow independent temperature control in different areas of the home. Proper setup helps improve comfort, reduce hot and cold spots, and use energy more efficiently.

Every installation includes verifying compatibility with your furnace, air conditioner, heat pump, hybrid heat system, or zoning equipment. Once installed, we test the thermostat, configure the settings, connect smart features when applicable, and show you how to get the most from your new thermostat.

Smart Thermostat Benefits

Modern smart thermostats offer more than simple temperature control. They make it easier to manage your home’s comfort, improve energy efficiency, and get the most from your HVAC system. With features like smartphone access, customizable schedules, and automatic temperature adjustments based on your routine, you can maintain a comfortable home while reducing unnecessary energy use. Many models also provide maintenance reminders, system alerts, energy usage insights, and support for zoning systems and multi-stage equipment, giving you greater control over your comfort whether you’re at home or away.

Our AC died during the hottest week in Summer of 2022. I called CenterPoint for service and they said they'll get to me in two weeks. I called Genz-Ryan on a recommendation from my in-laws and they had someone out the next morning helping me sort out what to do next. They are extremely prompt and professional. Every tech I worked with explained what they were doing and kept me informed on every step of the process. They might not be the cheapest company to go with, but if you want something done right, they seem like the correct company :)

Update for 2024- Had some extensive plumbing work done to fix some incredibly wild decisions the prior owner had made. Also replaced the water heater and softener. This was a multi-day project, but the crew was incredibly friendly and considerate. Everything has been running smoothly since!

Update for 2026- Had some plumbing work done this week and Jacob was phenomenal. Both with answering all my questions and explaining every step of the way. He was very considerate to keep certain doors closed as to not let cats in the basement or out of the house and his persistence to get everything done on the same day and not stretch the project into the weekend (probably for both our sakes :).

Genz remains to be a fantastic company to work with. Again, their prices are a big higher, but the quality they provide and commitment they have to maintaining that quality if something goes wrong is second to none.

Ryan L assisted with cleaning out our vents Nov 2026, he was super helpful and patient. Kept me informed every step of the way and also allowed us to move the cats between rooms. Thanks Ryan!

Great job! Excellent professional team who made certain everything worked to our satisfaction. The work required a followup visit which was completed with priority (next morning service). Jeremy and Kurtis are top notch skilled tradesmen, and kind and considerate guests in our home.
Highly recommended!

Ryan A. arrived to issue the quote that we requested to have our water heater replaced along with a non-functional water softener. Although it was not "cheap" by some standards, the service and overall quality of product, workmanship, and installation were top-tier. We are replacing previous owners quick fixes. When we do, it's to the highest level. Ryan covered everything that we had questions on, and was great to work with.

Shea (our installation technician) was awesome. He arrived early, and had a new water heater and softener completely replaced, and various other mechanical room adjustments done by 3:00 PM. Outstanding service without a doubt - especially because the mechanical room in our home is packed tight like a sardine can !

I have used Genz Ryan four times and have always had a good experience. Pricing is always fair. I like that I can text to set up appointments and check on when a technician will arrive.
Ryan did an amazing job. Great communication.

Levi stopped over this weekend to diagnose an issue with our furnace. He was able to quickly diagnose a faulty modulating gas valve. Unfortunately, he had to order the part, but clearly communicated the issue and scheduled the replacement within 2 days. Levi provided outstanding service and I trust the new valve will last considerably longer. Thanks, Levi! I appreciate you helping keep our house warm as the Minnesota season turns colder.
