Why are the Rooms in my House Different Temperatures?

Why are the rooms in my house different temperatures?

It’s a strange and sometimes irritating phenomenon. One room of the house is the perfect temperature. Walk into the next room, however, and you find yourself sweating and hot. Move to another room still, and it’s like a trip to the Arctic. Every room of the house settles at a different temperature, and you can drive your energy bills too high trying to compensate. Temperature sensor can help find temperature imbalances between rooms.

Why does AC temperature imbalance happen?

A number of factors contribute to room temperature imbalance. A heating and cooling system with a single thermostat reads the temperature in only that one place in your home. When that area becomes too warm or cold, the thermostat tells the system to turn on.

Multi-level homes often promote these imbalances. Natural convection lets heat rise, and fill vaulted ceilings or upstairs areas. This leaves the lower areas of the home cooler. A heating and cooling system which monitors the area near the thermostat and no other can’t keep up with the demands of different levels.


The rooms nearest your furnace or cooling unit will get the most conditioned air. Rooms which sit further away, at the ends of the ducts, receive far less conditioned air. This may make them warmer than the areas at the heart of the house. HVAC professional can diagnose thermostat issues and ensure all rooms are at the thermostat temperature for an acceptable temperature difference.

Environmental factors also play a role. East-facing rooms may become very warm in the morning, when the sun first rises, then cool as the day progresses. A room with huge windows can draw heat into that area and keep it there. A north-facing room can have the heat drawn out of it by chilly winds, while the rest of the house stays warm. Temperature sensor can help to identify rooms with room temperature different from the thermostat set by HVAC system.

Individual preferences can be the greatest influence of them all. Everyone has different opinions on the proper temperature for a room. Where one person hunts for a blanket to curl up under, someone else wants to know why it’s so hot in here. At night, a family member might like to sleep cold. The thermostat set and temperature sensor must meet everyone’s demands.

What can be Done About AC Temperature Imbalances?

Adjusting the thermostat temperature to compensate for temperature imbalances in your home’s different zones can be an expensive proposition. You can set the room temperature lower to eradicate hot spots, but that means paying more to cool areas which don’t need it. Flipping the levers on the vents to control air flow into the room will help, but there is a better solution using temperature sensor.

Zoning systems allow for control over individual areas of your home. Dampers isolate each vent to provide conditioned air only to the areas which need it. Individual thermostats serve each zone of your home, sensing the thermostat temperature in that area only. These thermostats link to a control panel, which handles requests from each thermostat on a first-come, first-served basis. HVAC professionals can check for thermostat problem if there is a room temperature different than thermostat set.

With individual thermostats in your home’s unique zones, you have precise control over your room temperature. Upper-floor rooms can receive more cool air than lower ones, or the too-cold room which chills rapidly can have more heat. The acceptable temperature difference between rooms can be set and adjusted according to your preference by an HVAC technician. The HVAC technician will utilize a temperature sensor to adjust the heat pump since it’s an important factor to maintain the desired set temperature.

Programmable thermostats help to even out the temperature of your home. A programmable thermostat offers the ability to set your system to adjust to your desired set temperature at certain times of the day. If you want to keep your home warmer during the day while you are out, then cool down half an hour before you usually arrive home, a programmable thermostat can do this. If you have issues with your thermostat temperature sensor or notice a temperature difference between rooms, it may be time to call an HVAC professional, particularly an HVAC technician specialized in thermostat problem.

Zoning systems and programmable thermostats do more than eliminate hot and cold spots in your home. These home comfort solutions can save energy and money as well. A zoning system delivers conditioned air only to the places which need it, which means your HVAC system will run less, and for shorter periods of time. Programmable thermostats automatically adjust the temperature in your home, without you needing to remember to change the thermostat temperature. No more forgetting to turn your heater down before you leave, only to find you heated an empty home all day.

Would a zoning system, or programmable thermostat set, benefit you and your family? If you notice rooms in your home which always seem too hot or too cold, a zoning system or programmable thermostat may both save you money and increase your comfort. A chat with an HVAC technician can offer you answers and solutions to all your HVAC needs. A temperature sensor can also help regulate the set temperature in your home.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.
