Thermostat Upgrades and Replacement in Columbia, SC

Your thermostat is the part of your heating and cooling system you deal with the most. A quick adjustment on the wall tells the whole system what to do. But when the thermostat is outdated or unresponsive, it shows up in uneven temperatures, higher bills, and a lot of frustration. That’s when it makes sense to look at a thermostat upgrade.

Cassell Brothers Home Services installs new thermostats for homeowners across Columbia, Lexington, Irmo, Chapin, and West Columbia. Whether you need a simple programmable model or you’re ready for a multi zone smart thermostat, we’ll help you choose the right fit and install it the right way. Our service professionals will work closely with you to ensure your home always has ample, steady heating and cooling.

Benefits of Installing a New Thermostat in the Midlands

Homes in the SC Midlands deal with hot summers, damp springs, and the occasional cold snap. Having a thermostat that can handle those swings makes daily life easier. Upgrading your thermostat gives you:

  • More consistent heating and cooling
  • Custom schedules that match your family’s routine
  • Energy savings that show up on your monthly bill
  • Remote access with Wi-Fi enabled smart thermostats
  • Zoned temperature control for larger homes or multi-level spaces
  • Less wear and tear on your furnace or AC

A thermostat may look like a small device, but it has a big impact. Installing a new thermostat keeps your system running efficiently and makes your home more comfortable year-round.

Regardless of the features you are interested in, the first thing you should consider is the accuracy of your thermostat. Older, mechanical thermostats are only accurate within a few degrees of the temperature setting you choose. Newer, digital thermostats, however, can be made accurate within 0.5 degrees depending on the HVAC system and air handler you have installed. Many new thermostats are also wireless as well as battery-operated, allowing you to move the thermostat to whichever room you are in in your home.

Programmable Thermostats vs Smart Thermostats

When you install a new thermostat, you’ll often choose between programmable and smart models. Both can improve comfort and efficiency, but they work a little differently.

Programmable Thermostats

  • Let you set daily or weekly schedules
  • Simple, reliable, and affordable
  • Good option if you want better control without added technology

Smart Thermostats

  • Wi-Fi enabled for adjustments from your phone
  • Learn your patterns and adjust automatically
  • Provide energy use reports and reminders
  • Integrate with other smart home devices
  • Can control multiple zones in larger homes

If you’re not sure which type is best for your household, Cassell Brothers Home Services can walk you through the options and help you install a new thermostat that fits your needs.

Best Thermostat Settings for Winter and Summer

Every home is different, but there are general settings that balance comfort and efficiency. Sticking close to these ranges helps reduce energy costs without sacrificing comfort:

Best Thermostat Settings for Winter

  • Around 68F during the day when you’re home
  • A few degrees lower at night or when you’re away

Best Thermostat Settings for Summer

  • Around 78F during the day when you’re home
  • Higher settings when the house is empty to save energy

Extra Tips

  • Avoid extreme temperature swings
  • Use ceiling fans to help circulate air
  • Consider zoning if your home has rooms that always feel warmer or cooler than the rest

We’ll be sharing more detailed thermostat setting tips in our blog, but these guidelines are a good starting point for the best thermostat settings for Midlands homeowners.

What Kind of Thermostat Do I Need for Zone Control?

Larger homes, multi-level houses, or families with different comfort preferences often benefit from zoning. A zoning climate control system lets you heat or cool different parts of the home separately, which saves energy and keeps everyone comfortable.

Thermostats designed for zone control include:

  • Multi Zone Smart Thermostats: Control different areas of the home from one app or interface
  • Programmable Zone Thermostats: Set unique schedules for each zone
  • Hybrid Options: Combine smart features with basic zone controls

Cassell Brothers can evaluate your home and recommend the thermostat that works best for your zoning setup. Whether you need a single replacement or an AC system designed to handle multiple areas, we’ll make sure your upgrade gives you reliable results.

Maintenance of Your Existing Thermostat

It’s important that homes in Columbia, Irmo, Lexington, and Chapin have their existing thermostats serviced on a regular basis. This can be done during a routine heating or cooling maintenance visit, or it can be done as a standalone maintenance call. Either way, thermostat service should be completed every year to test the accuracy of each thermostat in your home.

We recommend you check your thermostats periodically for accuracy as thermostat issues aren’t just issues of comfort, but of energy efficiency. If your thermostat is malfunctioning, thermostat repairs are available so long as the problem is small and the issue can be fixed in a single visit. Sometimes they can be recalibrated. Other times, it is best to replace the thermostat with a newer, more efficient model that matches the specific needs of your home.

If your thermostats are significantly inaccurate, malfunctioning or appear to not be working at all, call Cassell Brothers for service and one of our HVAC experts will check for problems.
