Why Are There Hot And Cold Spots In My House?

Having areas of uneven temperature in the homes can be a source of discomfort. The problem can be caused by something as simple as a blocked air vent or a more serious problem with their HVAC system. When it’s the former, a simple DIY solution can come in handy. But when it is the latter, you will need to contact a reputable HVAC contractor.

There are several reasons for uneven temperature across different areas of your home. We have listed some of the possible reasons for this below. 

HVAC Equipment Is The Wrong Size 

When getting an HVAC system, you should go for one that has the capacity to meet the cooling and heating needs of your home. Undersized or oversized systems would result in difficulties in regulating your home’s temperature. If the system is low capacity, it will struggle to warm or cool your home. If the capacity is too large, it will cause the system to short-cycle. That means it would only run for a short period before shutting off without cooling or heating your home properly. The best way to fix this is to get an HVAC with the appropriate capacity for your home.

Air Duct Leaks 

Air is circulated to different parts of your home through ductwork. A tear or gap in the ductwork would cut off or reduce the flow of cold or hot air to the affected area. To fix the problem, you may need to hire an HVAC technician. The technician would locate not only the area of the leak but also determine the best option between a repair and total replacement.

Blocked Or Closed Air Vents 

An uneven temperature in your home could be a sign of blocked air vents. If the vents in some parts of your room are blocked, there won’t be proper circulation of air in your home, hence the reason for the cold or hot spots. To solve this problem, check the vents in your home and make sure they are open and also not covered by pieces of furniture or rugs.

The landscape Of Your Home

The location of your house can affect the temperature in your home. For instance, if trees shade some parts of your room while other parts are exposed to sunlight, the area shaded by trees would naturally be colder, while the area receiving the heat from the sun would be warmer, especially during the summer. To control this, you can invest in energy-efficient windows such as cellular shades or thermal drapes. If this does provide much help during the summer, then you should go for a window film that can reduce solar heat gain.

Unsealed Windows And Doors 

Unsealed windows and doors are one of the common factors that contribute to the cold and hot spots in your home. The small gaps in your windows and doors cause air to leak into and out of your home, leading to fluctuations in your home’s temperature and also increasing your energy bills. Energy experts estimate that one-third of heat loss in the home happens through windows and doors.

Dirty Air Filter 

A dirty air filter also accounts for one of the most common airflow issues. When the filter is clogged with dirt, the HVAC system works harder to get the air through it. This puts a strain on the HVAC system and also reduces airflow to your home. The reduced airflow increases the time it takes to regulate your home’s temperature. Before suspecting if there’s a serious problem with your HVAC system, be sure to check for dirty air filters first. It is generally recommended to clean your filter every three months, or you can opt for a disposable filter.

Bad Thermostat Location

Your HVAC thermostat shouldn’t be placed in an area with exposure to direct sunlight or any other heat source. This is to prevent it from taking a wrong reading and adjusting your home temperature according to the readings. So you should check your thermostat location once the temperature doesn’t feel right. 

Having cold or hot spots in your room could be a result of some or all of these factors. While you may not be able to fix some of the problems yourself, an HVAC contractor would be able to handle all the problems with no difficulties. A stabilized temperature all year round would not only keep you comfortable but also save you from the cost of high energy bills. So, do not hesitate to hire a technician if you notice a fault with your HVAC system.
