cold spots in house

Have you ever wondered why some rooms in your house feel like a sauna while others resemble a freezer, even with the AC running?

We even have a new service dedicated to fixing your hot and cold spots – introducing our Sunny Room Comfort Service! It’s the perfect solution for an easy, cost-effective way to make sure your home is more energy-efficient and temperature-controlled.

Common Causes of Hot and Cold Spots in a Home

Ductwork Issues

Uneven Air Distribution: In your house, clogged or obstructed ductwork may cause problems with air balance. To prevent problems, it’s critical to get duct cleaning done regularly. Your HVAC system may run longer and more frequently if there are blocked ducts, which might prevent certain rooms from receiving hot or cold air.

Duct Sizing Problems: Inconsistent sizing of ducts can lead to temperature imbalances in your home. Check if air is flowing through the ducts during the system’s operation. If there’s no airflow, it could be due to leaky or damaged ducts. Ducts should be sealed to prevent air from escaping into attics, basements, or crawl spaces. If there are holes or faulty connections, some air may escape.

Insulation Problems

Insufficient Insulation: Poor insulation can have an impact on the energy efficiency and air balance of your house. In the winter and summer, a home with insufficient insulation will require extra heating and cooling. 

Gaps in Insulation: Gaps in insulation or poor installation can cause uneven heating or cooling. This is especially evident near walls, attics, or basements.

Thermostat Placement and Functionality

Poor Thermostat Placement: Direct sunlight can cause false readings, leading to premature heater shut-offs and air conditioners running. Placement too close to heat sources can also cause higher temperatures. Dirt accumulation on the inside of the thermostat can cause inaccurate readings. Old, inaccurate, or broken thermostats may require replacement. For optimal comfort, consider zoning your home and consider upgrading to a more accurate digital model.

Outdated Thermostats: If you have uneven temperatures in your home, you might want to consider updating your thermostat. For example, many newer thermostats include modern features like remote sensors for better temperature control. They are almost always programmable as well, meaning they can automate your home’s heating and cooling based on your patterns, saving energy and creating a balanced indoor climate.

Air Balancing Issues

Inadequate Return-Air: An uneven distribution of air could be the result of a lack of return-air vents.

Blocked or Closed Vents: An easy possible way to fix your hot or cold spots is to check the vents in every room in the house. There may be hot or cold areas in a room due to blocked or closed vents.

External Factors

Sun Exposure: Rooms with excessive sun exposure can become uncomfortably hot, especially in the summer.

Structural Variations: Uneven temperatures in your home could be due to variations in room size, the height of your ceiling, or the size of your windows.

How to Identify Hot and Cold Spots

Signs to Look For

Temperature Differences: Check all air vents and remove any obstructions. Keep HVAC vents open and reposition items for free airflow. Check for drafts in windows, doors, and joints and repair them if necessary. Inspect outdated insulation or older homes for temperature fluctuations. 

Uneven Heating/Cooling: Consider using good thermostats and zoning to create a balanced environment in each room.

Tools and Techniques

Temperature Recording: Use tools like thermometers or infrared thermometers to detect hot and cold spots around your home.

Professional Assessments: The most comprehensive way to fix the uneven heating in your home is to put your trust in the experts who put comfort first. The Sunny Room Comfort Service by Sunny Service provides a thorough assessment, including accurate recorded temperatures in each room and an insulation assessment.

Effective Solutions for Fixing Hot and Cold Spots

Improving Ductwork

Duct Sealing and Insulation: Sealing and insulating ducts can improve air distribution.

Damper Adjustments: Adjusting dampers can help balance airflow to different rooms in your house.

Enhancing Insulation

Adding or Upgrading Insulation: A properly insulated ductwork system is essential to sustaining stable temperatures. When there are leaks, air cannot properly enter your home through the HVAC system.

Sealing Gaps: Sealing gaps in insulation prevents temperature fluctuations which helps your home maintain the desired temperature.

Optimizing Thermostat Use

Install Remote Sensor Thermostats: For a more accurate way to control the temperature throughout your home, we recommend you upgrade to a thermostat with remote sensors.

Proper Thermostat Placement: The optimal thermostat location in your home is in the center, away from hot appliances or sunlight. This ensures accurate temperature readings and prevents skewed readings, as the thermostat’s placement helps regulate the overall temperature accurately.

Air Balancing Techniques

Vent Adjustments: Proper airflow is crucial for maintaining even temperatures. Heavy drapes or large furniture in front of vents can hinder natural airflow, causing temperature variations. To improve airflow, rearrange your furniture and test if it improves room temperature.

Installing Additional Return-Air Vents: Adding return-air vents can help balance airflow.
