Ever set your thermostat to 22°C and still feel like you’re freezing? Or maybe your home is sweltering even though it reads 20°C? You’re not imagining things — sometimes thermostats really do lie. Small issues with placement, calibration, or environmental factors can make your home feel less comfortable than your thermostat indicates.
In this post, we’ll show why this happens and how to fix it — including when to call in Econoair’s HVAC heating and cooling services for professional help.

Econoair’s HVAC heating and cooling services offer 24/7 emergency support and trusted solutions for over 20,000 Toronto customers.
Your thermostat is the command center for your home’s comfort, but it only measures the temperature where it sits — not everywhere in your house. That means the reading can be skewed by sunlight, drafts, poor placement, or even the type of thermostat you have.
Many homeowners blame their furnace or air conditioner for uneven heating or cooling, when in fact the thermostat is the real culprit. Misreading temperatures can cause your HVAC system to overwork, wasting energy, increasing bills, and creating hot or cold spots in your home.
With Econoair’s professional HVAC heating and cooling services, you don’t have to guess what’s going wrong. Our licensed technicians diagnose thermostat issues, ensure your system is properly calibrated, and check that your heating or cooling system is balanced for optimal comfort. With over 20,000 satisfied customers, we’re trusted for fast, reliable service across Toronto and the GTA — including emergency repairs 24/7.
Where your thermostat is installed can have a huge impact on how accurately it measures your home’s temperature — and, by extension, how efficiently your HVAC system operates. Many homeowners unknowingly place their thermostat in locations that give misleading readings, like near windows, doors, drafts, vents, or heat-producing appliances. For example, if a thermostat is directly exposed to sunlight in the afternoon, it may think your home is much warmer than it actually is, causing your furnace to stay off when you really need heat. Conversely, if it’s in a drafty hallway or near an exterior door, your system may run constantly, thinking the house is colder than it is — which increases energy bills and wears out the furnace faster.
✅ Fix: The ideal thermostat location is on an interior wall, away from direct sunlight, vents, and major heat sources. Our Econoair HVAC technicians can perform a full home evaluation to determine the best placement for your thermostat, ensuring your heating and cooling system responds accurately to the actual temperature of your living spaces. Proper placement not only improves comfort but also reduces energy consumption, helping you save money while keeping your family cozy. And if anything ever goes wrong, Econoair offers 24/7 emergency service, trusted by over 20,000 customers across Toronto and the GTA.
Even the most carefully placed thermostat can give inaccurate readings if it isn’t properly calibrated. Over time, thermostats — especially older analog or mechanical models — can drift, meaning the temperature they display doesn’t match the actual room temperature. A difference of just 2–3°C can make a room feel noticeably colder or warmer than expected, leaving you frustrated and unsure if your furnace or AC is functioning correctly. Miscalibration can also cause your HVAC system to cycle inefficiently, turning on and off too frequently, which puts unnecessary strain on the equipment and can shorten its lifespan.
✅ Fix: While some digital thermostats allow for manual recalibration, it’s often best to have a licensed HVAC professional handle the process. Econoair’s technicians have the tools and experience to calibrate your thermostat precisely, ensuring your heating and cooling system operates as intended. Accurate calibration improves comfort, reduces energy usage, and prevents costly wear and tear on your furnace or AC. And if your system ever malfunctions or fails completely, Econoair’s 24/7 emergency service ensures that help is always just a phone call away.
Your thermostat measures the temperature where it sits, but it can’t distinguish between actual room temperature and heat generated by environmental factors. Direct sunlight, heat from electronics, nearby kitchen appliances, or even a fireplace can all trick your thermostat into thinking the room is warmer than it is. On the flip side, cold drafts near windows or exterior doors can make a thermostat think the house is colder, triggering the furnace unnecessarily. These environmental influences can cause uneven heating or cooling, making some areas of your home uncomfortable while others are over-conditioned.
✅ Fix: Simple adjustments like closing blinds, moving heat-generating devices away from the thermostat, or installing draft blockers can help reduce these distortions. For more precise results, Econoair’s HVAC technicians can recommend or install advanced smart thermostats that account for environmental factors and communicate directly with your heating and cooling system to maintain even temperatures throughout your home. This ensures your home stays consistently comfortable while improving energy efficiency — and with 24/7 emergency support, you’re never left in the cold (or heat) when unexpected HVAC issues arise.
Sometimes the thermostat isn’t lying — the problem may be uneven airflow or improper system balance. Poor ductwork design, blocked vents, or leaking ducts can create hot and cold spots in your home, making one room sweltering while another feels freezing. Even if your thermostat is perfectly placed and calibrated, these airflow problems can prevent your furnace or AC from distributing air evenly, leaving your home uncomfortable. Over time, this can force your HVAC system to work harder than necessary, increasing wear and energy costs.
✅ Fix: The solution is a comprehensive assessment of your home’s HVAC system. Econoair’s licensed technicians inspect ductwork, check for blockages, balance airflow, and ensure your heating and cooling system operates efficiently throughout every room. With our professional adjustments, your home will maintain a consistent temperature, improving comfort and energy efficiency. And because problems can happen at any time, Econoair offers 24/7 emergency services, so if your furnace fails on a freezing night or your AC goes out during a heatwave, we’ll get your system back up and running fast.
Sometimes the thermostat itself is simply outdated. Older models, especially mechanical ones, are less accurate, slower to respond, and lack features that optimize efficiency. Modern smart thermostats, on the other hand, can learn your schedule, detect temperature trends, and communicate with your HVAC system to save energy while maintaining comfort. They can even be controlled remotely, allowing you to adjust your home’s temperature from anywhere.
✅ Fix: Upgrading to a modern thermostat can make a noticeable difference in comfort and energy savings. Econoair’s HVAC experts can assess your system, recommend the best smart thermostat for your home, and handle the installation so it works seamlessly with your heating and cooling equipment. Whether you’re trying to reduce energy bills, improve comfort, or add convenience to your daily routine, this upgrade ensures your home environment is precisely controlled. And, of course, if you ever experience a malfunction, Econoair provides 24/7 emergency service, trusted by over 20,000 customers, keeping your home safe and comfortable no matter the season.
Your thermostat only measures the temperature at its location, not in every room. Factors like sunlight, drafts, nearby heat sources, or poor airflow can make your home feel warmer or colder than the reading. Older thermostats may also be miscalibrated, giving inaccurate readings.
✅ Solution: Have a licensed Econoair HVAC technician check your thermostat placement, calibration, and system balance. We ensure your heating or cooling system responds accurately to real conditions, keeping your home comfortable. And with 24/7 emergency service, we’re always ready if your HVAC system needs immediate attention.

Absolutely. Direct sunlight can make a thermostat think your home is warmer than it is, while drafts from doors or windows can make it seem colder. Both situations can cause your HVAC system to run unnecessarily, wasting energy and creating hot or cold spots.
✅ Solution: Adjust thermostat placement or install smart thermostats that account for environmental factors. Econoair’s HVAC heating and cooling experts can recommend the best setup for your home, optimizing comfort and efficiency while reducing energy costs.
Mechanical thermostats can last 10–15 years, but older models are less precise and lack energy-saving features. Digital or smart thermostats often last longer and provide better efficiency, remote control, and scheduling options.
