Multiple Story Home

Heat tends to rise, so it's not uncommon to feel warmer when you're on the second floor of your home. If there are any inefficiencies in your HVAC system or even insulation issues in your home, you'll probably notice the difference in the upper level before it becomes a problem on the ground floor. This only accounts for some of the extra heat, however. The most common culprit is a lack of insulation. Since your roof is exposed to the sun all day, the insulation in your attic is meant to prevent that heat from transferring into your second-story rooms. If the insulation is insufficient, hot days will result in warmer temperatures at the top of your stairs.

Accidentally Closed Supply Vents

Supply vents could be one simple culprit to variable temperatures in your rooms. Cool air is blown through your supply ducts to distribute it through your home and enters the rooms of your house through the supply vents. If one or more of the vents in a room are closed or obstructed, this prevents the cold air from getting in. If this is the issue, clear or open the vents and give the room a few AC cycles to reach the desired temperature. It's also a good idea to make it a habit to check your vents occasionally when you're in the room to ensure your AC isn't working cold air through your system without providing the cooling you need.

Inadequate Number of Return Vents

Return vents are used to suck the warm air from each room so it can be cooled before being redistributed. This keeps your air flowing in a cycle through the system and levels out the room's air pressure while the AC or heater is in operation. If a room in your home tends to be warmer than the others despite your AC performing well, you could need additional return vents in that room. Old HVAC systems used to rely on a single return vent in a central location in the home, but modern systems generally have at least one in each room but work more efficiently with two or three. An HVAC professional can tell you whether additional return vents are needed for an area of your home.

Poor Insulation

Just like the impact on the upper floor of a home, poor insulation in other areas can also ensure some rooms are hotter than others on the ground level. Homes that lack insulated walls or windows often suffer from hotter rooms on the sunny side of the home, especially when the sun is positioned to hit the house directly. This can be somewhat mitigated with HVAC zone control if it is a feature on your system. What is the zone control system? It allows dampers within the ductwork to be open and shut to support varied temperature settings from multiple thermostats. Each zone in your home gets its thermostat so you can control the temperature independently of the rest of the house. However, a better solution to poor insulation might be improving the situation to give your home an energy efficiency makeover.

Duct Leaks

If the previous issues don't fit your situation, the problem could be leaky ducts. If you have leaks in your ductwork, cool air escapes before it reaches your supply vents. This reduces the amount of cold air being pumped into the room, making it harder for the HVAC system to maintain the temperature you want. Duct leaks cause some rooms to be uncomfortable and force your AC to work harder to lower the temperature in your home. This can reduce the lifespan of your AC unit and dramatically increase your energy bill as the AC kicks on more frequently in an attempt to do its job properly. Fixing leaky ducts should be a high priority to maximize your investment in your HVAC system and prevent unnecessary wear and tear on the AC unit.

Improperly Sized AC System

If none of the above provide solutions to your inconsistent room temperatures, it's possible that the AC system you have installed isn't the correct size for your home. An AC system that is too small will still manage to keep some areas of your house cool but won't have the power to maintain even temperatures throughout the entire area. Generally, vents closer to the AC unit blow the coldest, while those in rooms furthest away only get whatever cool air is left over. If you have a zone control system, this can be slightly mitigated by opening and closing the zones to maximize cooling in the areas you need most. However, forcing an AC system to cool a home beyond its abilities will reduce the years you get out of it.
