Is your living room an icebox while your upstairs bedroom feels like a sauna? You are not alone. Hot and cold spots are one of the most common complaints homeowners face, particularly in multi-story homes, homes with open floor plans, or houses with sunrooms.
At Lakeside Heating, Cooling & Plumbing, we believe your home should be comfortable in every room, not just next to the thermostat. Here is our guide to understanding why this happens and how to fix it, from simple fixes to permanent solutions.
Why Do I Have Hot or Cold Spots?
Before diving into repairs, it helps to understand the culprits. Often, uneven temperatures are caused by:
- airPoorly Designed Ductwork: Kinks, undersized ducts, or too many bends.
- homeInsulation Issues: Poorly insulated attics or walls letting in heat.
- blockBlocked Vents: Furniture, curtains, or rugs obstructing airflow.
- speedSystem Overwork: An undersized or oversized HVAC unit.
Simple, No-Cost Solutions (Try These First)
- check_circleOpen All Vents: Contrary to popular belief, closing vents in unused rooms strains your system and creates uneven pressure.
- check_circleClean/Replace Air Filters: A dirty filter restricts airflow, usually affecting rooms furthest from the unit first.
- check_circleCheck Ceiling Fan Directions: In summer, fans should run counter-clockwise to pull hot air up. In winter, clockwise to push warm air down.
- check_circleUse Curtains: Close blinds or curtains on south- and west-facing windows to block solar heat gain.
Duct Modification: Balancing Your Airflow
If the simple fixes don't work, your system might need an air-balancing session, or the ductwork may need adjustments.
Adjusting Dampers: Most HVAC systems have manual dampers in the ductwork near the unit that can be adjusted to direct more air to specific rooms.
Sealing Leaky Ducts: Leaky ducts are a major cause of energy loss. Using mastic sealant or metal-backed tape can ensure the air reaches its destination.
Adding Return Air Vents: If a room has plenty of supply air but still feels uncomfortable, it might lack a proper return path. Adding a return duct or a "jumper duct" allows air to circulate properly.
Adding a New Supply Duct: In extreme cases, our team can add a new duct run to deliver more conditioned air to an uncomfortably hot or cold room.
