One of the worst things that you can have in a house is cold spots. Even worse though, is several cold spots at once! Cold spots in your home are often from issues with the duct system to a full malfunction of the whole HVAC system.

If parts of your house are icy cold, don’t blame the poltergeist. Instead, examine some of the most important causes of cold spots, or call a professional for an inspection of the house.

What Causes Cold Spots in a House?

1. Duct Issues

Most traditional HVAC systems use a vent/duct system that runs throughout a house. All the channels connect to the main air conditioning system. Ducts are one of the most common components that can cause an issue, from a common blockage to leaking air vents. The first thing you will want to do is take a closer look at what’s going on in the air ducts.

2. Any Unsealed Structural Leaks

Air leaks can happen anywhere in the home, especially where the house connects to the outdoors. If you have any doorframes or windows that are not sealed properly, then you should have them inspected. Cold spots are inevitable if your house is allowing any cold air in.

If you suspect an air leak, check for cold spots and try to track them down to any small drafts coming through the cracks of your windows and doors. In some cases, small beams of light can reveal the site of air leaks.

3. Lack of Insulation

Insulation is one of the most important things for the structural integrity and comfort of your home. While insulation is installed during the building phase, it can need upkeep throughout the lifespan of a house. This is important to control the temperature in your home. You may have to deal with cold spots from room to room if your home lacks sufficient insulation levels or has undergone damage over time.

Proper insulation of the home can take care of hot and cold spots and help you save money by lowering your heating and cooling bills.

4. Zoning Systems

Modern and more advanced HVAC systems are designed to allow users to set the individual indoor temperatures of each room or area in the house. Of course, some older HVAC units don’t have this benefit. What’s called “zoning” can have a huge impact on the heat of the rest of the house.

If you are reliant on an old HC or HVAC system in the home, consider upgrading your HVAC system to one of the newer models that allows for individual hot or cold settings. This is called “zoning” and can have a huge impact on the heat of the rest of the house. Poorly designed zoning setup can affect both warm and cool air in areas of your home.

5. HVAC Malfunctions

Another common cause of hot and cold spots in your home can be the malfunctioning of your entire HVAC system. HVAC problems can include anything from a short circuit to residual dust.

If the house doesn’t appear to be what the thermostat claims or some of the house has suddenly gone cold, then you should have the system looked at by a professional.

An HVAC inspection is what you need if you suspect that there’s a larger problem that could have shut down most of your AC system. If there are big cold areas in your house, it’s more likely that this is the issue.

6. Thermostat Issues

If the thermostat temperature doesn’t match the rest of the house, it’s likely the thermostat’s fault.

Thermostat issues are usually minor, but the issues can have a big impact on the temperature control in our home. Uneven temperatures and cold spots are common indications of this issue.

Check the temperature on the thermostat against the cold spots in the house to help spot the issue.
