Outdated thermostats can lead to more than just discomfort – they can contribute to issues within your HVAC system. Are you experiencing frequent on-and-off cycles from your heating or cooling system?

Does the displayed temperature seem inaccurate compared to the actual feel, forcing you to constantly adjust the thermostat but never achieve the right level of comfort? These could be signs of a malfunctioning thermostat.

A failing thermostat can confuse your HVAC system, causing it to short cycle in an attempt to maintain the desired temperature. This not only leads to uneven heating and cooling, but it also puts unnecessary strain on your HVAC equipment.

Prolonged wear and tear like this increases the chance of a premature breakdown. New thermostats offer precision temperature control to avoid the issue of cycling on and off, and more advanced smart thermostats are often equipped with self-diagnostic features.

There are many benefits to having a new thermostat installed:

  • Greater comfort
  • Remote temperature control
  • Smart technology
  • Quick and easy installation
  • Reduced energy bills

A modern thermostat is a powerful tool for managing your home’s comfort and potentially avoiding future HVAC issues. Instead of wrestling with the thermostat, let the smart thermostat adjust the temperature to your pre-programmed preference. But what if something seems off?

Modern thermostats can provide valuable insights. Let’s say your system is short cycling, rapidly turning on and off. An older thermostat wouldn’t offer any explanation, but a smart one might display an error code or send you an app notification, indicating a potential sensor issue.

This early warning allows you to address the problem before it spirals into a major repair, saving you time, money and frustration. Environmental Heating & Air Solutions‘s experts can assess your current thermostat and recommend the perfect upgrade for your needs and budget.

Our technicians will professionally install it, walk you through its features and answer any questions you may have.
