A thermostat is a simple device with a straightforward task: to tell your HVAC system what to do. It usually works unnoticed and does its job well. However, when it fails, everyone in your family will experience discomfort. If you’re dealing with a faulty thermostat, you may not have the peace and comfort you desire in your home.

Marsh Heating and Air Conditioning is your preferred HVAC company in Ramsey MN. We offer outstanding home comfort products, including smart thermostats.


Several indications are telling you that your existing thermostat is due for a replacement. Here are some of them:

The screen won’t turn on.

A thermostat screen that doesn’t turn on or is only displaying data part of the time can cause problems with your heating or cooling system. This problem can be fixed simply by resetting the thermostat (turning it off and back on).

Having said that, there are times when the thermostat needs to be replaced altogether, especially if there are electronic issues. Most of these issues are covered by the warranty, so check your warranty certificate to be sure.

Your HVAC system won’t turn on.

No matter what kind of HVAC system you have, you can detect a thermostat problem if the system fails to power on. It occurs when there is something wrong with the wiring that connects the HVAC systems, or maybe the thermostat is sending the wrong signals or commands. Also, it could be reading temperatures wrongly and as a result, it fails to turn the system on.

These types of issues require professional inspection, so it’s best to consult a qualified HVAC technician to assess whether a repair job is necessary or a replacement is a permanent solution.

Features of the Lennox ComfortSense 7500 Touch Screen Smart Thermostat

Customizable settings for every day of the week allow you to control your heating and cooling around your family’s schedule. And with just one touch, you can put the thermostat into an energy-saving Away Mode. 

When connected to a Lennox®heat pump and Lennox furnace, the ComfortSense®7500 will automatically switch between electric and gas operations to keep you warm, based on whichever is most cost-effective.

Like most thermostats, the ComfortSense® 7500 gives you the option of programming a setback temperature that allows you to save energy when you’re gone for the day. A key difference is that ComfortSense 7500 steps up performance before you step through the door upon your return home.

Energy Reports let you compare your monthly heating and cooling usage. Using this information, you can adjust your settings as needed to reduce energy consumption and utility bills.

The large touchscreen with adjustable brightness makes programming simple. An option for displaying outdoor temperature helps you keep tabs on what’s going on outside.

Its versatile programming options offer custom comfort and energy savings.

Smooth Setback Recovery senses extreme temperature changes and begins the temperature recovery process up to 2 hours before the programmed time.

One-Touch Away Mode overrides your regular programming schedule when you’re away and automatically turns down heating or cooling to save energy.
