CareersIt is common for homeowners living in two-story houses to grapple with the puzzle of a sweltering upstairs and a chilly downstairs during summer. You might consider the installation of a new air conditioning unit to rectify this, or this could simply mark the beginning of your quest for a solution. Understanding the airflow within your house and determining the areas where the balance of temperature is compromised might hold the key. Let’s find out why.
Reasons for Temperature Variances
Adjusting your thermostat in an attempt to rectify this problem only makes your downstairs freezing cold, escalating the already burgeoning issue. Here are 2 factors that might lead to temperature imbalance between your upstairs and downstairs and how you could address them to fix your heating and cooling problem.
1. Your Heating and Cooling System Can’t Serve Both Floors
When your house’s HVAC system fails to maintain identical temperatures upstairs and downstairs, you grapple with these inconsistencies in different areas of your house. Utilizing a zoned heating or cooling system in your house can be an effective solution for such issues.
A zoned heating or cooling system partitions your house into distinct zones, like the upstairs and downstairs, to enable you to cool the hot upstairs and heat the cold downstairs. This radiant solution is often complemented with strategically placed registers and carefully sealed doors and windows to prevent any drafts that might disrupt the balance.
How a Zoning System Works to Solve Uneven Heating and Cooling in a Two-Story Home
Zoning systems can be implemented in two ways:
Multiple Thermostats
A thermostat is installed in each of the two zones in your house (upstairs and downstairs), most commonly near windows or doors to aid homeowners to control the airflow through the electronic dampers in your air ducts. Paired with suitable weatherstripping, this adjustable setup ensures that you can recalibrate your upstairs thermostat to lower the excessive heat and adjust the one downstairs to warm up the zone.
Electronic-Based Dampers in the Ducts
The second approach is to install electronic dampers in your house’s ductwork. These devices act like valves, opening and closing to regulate the airflow of your house’s heated or cooled air.
2. You Have Poor Attic Insulation, Leaking Air Ducts or Blocked Soffit Vents.
Poor attic insulation, leaks in air ducts, blocked soffit vents, and a neglected basement can also contribute to the problem of a hot upstairs and a cold downstairs challenge in your home.
Poor Attic Insulation
To check if your attic is sufficiently insulated or not, look out for attic floor joists. If you can see any joist then your attic is not adequately insulated. Call a professional heating and cooling company for assistance or follow this guide to fix the issue DIY style.
Leaking Air Ducts
If the HVAC’s air ducts connected to your upstairs are leaking, it means their function is impaired, making the upstairs overheated. Engage services to repair these ducts to halt the leakage or opt for a replacement.
Blocked Soffit Vents
Soffit vents are located at the lowest points of the roof. They allow free airflow into the attic from the outside environment. When your soffit vents become obstructed, no air circulates into the attic. Poor insulation of the attic could be the reason the vents are impeded, causing your upstairs to heat up. Unclog your vents to allow the free flow of air.
Other Common HVAC Problems
Other common problems your heating and cooling system might experience include: contamination, scaling, corrosion, and a lack of ceiling fans. These complications can reduce the efficiency of cooling systems and should be addressed promptly when detected. As you tackle your heating issues, get your system inspected for these other potential challenges as well.
Remember, The Cooling Company is at your service for all your zoning needs if your house has a hot upstairs and a cold downstairs, or you could use the HVAC installation online estimator form for determining various costs. Be it basement issues or the need for installing roof or ceiling fans, holistic solutions can ensure a balanced, comfortable room temperature within your home.
