Most people focus on the HVAC unit for efficiently heating and cooling their homes.
They often consider its age, whether it’s due for maintenance, or whether it’s time for a replacement. However, your thermostat’s location is one frequently overlooked factor that can quietly impact your home’s comfort and energy bills.
At Thomas Hoffmann Air Conditioning & Heating, we’ve helped homeowners across St. Louis and the surrounding areas identify these hidden issues. If your home feels too hot, too cold, or inconsistent from room to room, your thermostat’s position could be part of the problem.
I’ve been using “THOMAS Hoffmann Airconditioning and Heating LLC” for years now. We have a 30 +\- year old system that works perfectly for us. Although we’ve not had to use it yet, it is comforting to know they offer a 24 hour on call service. I really appreciate that the technicians don’t try to upsell us on anything. They’re a very professional, knowledgeable, and courteous, local-family owned and operated business. I’ve also found their pricing to be very fair and by”fair” I don’t mean “cheap” but reasonable… especially for the quality of service provided by THOMAS Hoffmann HVAC. I love supporting smaller family owned business and this one is top-notch! Thank you guys!

0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.
Response from the owner:Hi there. I am unable to locate your customer profile. Please give our office a call at 314-471-7625 so we can get this figured out for you.

I will always call Hoffmans for my air and heat needs. They were out to my daughters house that day and fixed it. It was right before the weekend storm with below zero temps the next day. They saved my daughter and grandbabies. I could never thank them more.
Response from the owner:We are so happy to hear that we could help! Thank you for the kind review.
Snow and drifting snow covered intake and out take vents causing the furnace emergency to shut off furnace. Cleaned off the driftibg/ snow off roof and vents furnace works perfect now. Thank you and great job Nick.

Why Thermostat Placement Matters
Your thermostat monitors the temperature of the surrounding air and signals your HVAC system to heat or cool accordingly. But if it’s in the wrong spot, it may get a skewed reading, which leads to a chain reaction of inefficiency.
Here are a few key examples:
Too Close to Heat Sources: If your thermostat is near a window with direct sunlight, close to an oven, or located above a supply vent, it may read the room as warmer than it is. That means your AC might kick on more often than necessary, overcooling the rest of your home.
In a Drafty Hallway or Exterior Wall: A thermostat near doors or exterior-facing walls can register colder-than-average temperatures, causing your furnace to run longer.
Far From Main Living Areas: If your thermostat is in a guest room, hallway, or tucked away in a corner of the house, it may not reflect the temperature where your family spends time. That leads to hot and cold spots that are difficult to balance.
Signs Your Thermostat Might Be Poorly Positioned
Wondering if your thermostat is in the wrong place? Here are a few red flags:
One room always feels too warm or cold
Your HVAC system short cycles (turns on and off frequently)
Uneven temperatures throughout your home
Higher-than-normal utility bills
Constant thermostat adjustments with little result
These symptoms could also point to other HVAC issues, but thermostat location is a simple, low-cost factor worth evaluating early in the process.
Ideal Thermostat Placement
While every home layout is different, the general rule of thumb is to place your thermostat:
On an interior wall
In a central location, like a hallway near the main living areas
Away from windows, vents, kitchens, and other heat-producing appliances
About 52–60 inches from the floor (eye level)
This helps ensure the thermostat gets an average temperature reading from a well-used area of the home, not an outlier.
