It’s not uncommon to have hot and cold spots in your home, especially if your HVAC system is aging or if it is not properly balanced. If you’re uncomfortable in your own home, it’s time to take action and find out what’s causing the issue.
1. Temperature Difference In The Home
A temperature difference of 5-10 degrees is a good starting point for a thermostat setpoint, but some homes have a larger variation in temperature throughout. If you have areas, specifically rooms, that are much hotter or colder than this range, it’s time to call your local technician for a tune-up.
2. Age Of The HVAC System
If your system is more than 10 years old, it might be time for an upgrade. An aging system will not work as efficiently as a newer one, meaning you could be losing money on your energy bills. It’s also likely that your system is not operating with the same balance it once did.
3. Location Of The Furnace Or Air Conditioner
Furnaces and air conditioners need to be installed in an area of the home where they can do their job with ease, so if yours is located in a spot that’s easily obstructed by furniture or other household items, it may not be able to run with optimum efficiency.
4. Insufficient Air Flow
If you have registers or cold air returns connected directly to your furnace or air conditioner that are covered or restricted in any way, then it will significantly affect the performance of the system. Take a look at them and make sure they’re clear of anything that could prevent proper airflow.
5. Not Enough Or Too Many Vents In Your Home
Your HVAC system is designed to optimize the temperature throughout your home based on how it calculates heat loss from each room. If you do not have enough vents for proper airflow, then either your home isn’t properly cooled or heated based on who many rooms you have, or your system is working extra hard to provide enough heating or cooling. If you have too many vents and a significant temperature struggle a common solution might be to plug some of the vents in your home so that not as much airflow reaches each room.
6. Cold And Hot Spots In Your Home Might Be Related To Windows And Doors
If there’s a window or door that lets cool air escape from your home during the summer, then it will remain hot. You will constantly feel warm because this opening allows heat from inside the house to escape without being replaced by cool air from outside of the home. For winter months, if cold drafts enter your home from an exterior door or window, this can cause a room to be much colder than the other rooms in your home. You can address this issue by installing weatherstripping or caulking around doors and windows, or by using a door sweep on exterior doors.
7. Electrical Appliances
Large appliances, like refrigerators and washing machines, generate heat that can warm up an entire room. If you have several appliances running in one area of your home, it’s likely that this is contributing to the hot and cold spots you’re experiencing. Try to avoid placing electronics and appliances near vents or areas where people spend a lot of time.
8. Orientation Of Your Home
If your home isn’t oriented correctly, it could be causing problems with your HVAC system. Homes that have rooms facing direct sunlight in the summer can become extremely warm, and homes with windows that face north can be difficult to heat in the winter. If you’re uncomfortable in your home, take a look at its orientation and see if there’s anything you can do to make it more comfortable.
While it’s not always easy to diagnose the cause of temperature inconsistencies in your home, it’s important to take action if you’re uncomfortable. By addressing some of these common issues, you can help your HVAC system run more efficiently and help to create a more balanced environment in your home.
