Understanding Raised Ranch Homes in the Lower Hudson Valley
Raised ranch homes are among the most common house styles in the lower Hudson Valley and Westchester area. These popular homes typically feature:
- A garage on the lower level with a finished basement
- Bedrooms on one side of the upper level
- An open-plan living room and kitchen on the other side
Common Challenges with Raised Ranch Homes
These homes present unique HVAC challenges:
Limited Ductwork Options
The finished lower level leaves little room to run ductwork, making traditional HVAC upgrades difficult.
Uncomfortable Living Spaces
Living areas above unconditioned garages often experience temperature discomfort. In many older homes, the space between the garage and living areas lacks proper insulation.
Poor Insulation
Older raised ranch homes frequently have inadequate attic insulation, and we’ve even found uninsulated ductwork running through garages.
Oversized & Problematic AC Systems
Many homes have been retrofitted with oversized air conditioning systems in the attic. When we perform proper load calculations, we often discover:
- Significantly oversized air conditioners
- Biological growth and mold in existing ductwork
- Inefficient hydronic baseboard heating systems
Our Recommended Approach
First Steps: Insulation Upgrades
Before any HVAC work begins, we recommend:
- Upgrading attic insulation
- Improving insulation between the garage and living spaces
- Insulating any exposed ductwork
The Optimal Heat Pump Solution
For raised ranch homes, we recommend a hybrid approach:
Upper Level: Ducted System
A ducted heat pump system in the attic serves:
- Three bedrooms
- Bathrooms
- Living room
- Kitchen
- Dining area
We install individual returns in each bedroom for better balance, especially when doors remain closed. This is more effective than a single central return in the hallway. I did this in my own home and immediately noticed a difference in my kid’s rooms. – When paired with other IAQ upgrades like ERV’s and Ionizers, it really goes a long way.
Lower Level: Mini-Split Heads
Since ductwork can’t be installed in the finished lower level, we use ductless mini-split heads for the two or three rooms typically found there.
Bonus Spaces
Enclosed porches, sun rooms, or converted deck spaces require their own dedicated systems, as they’ll never match the thermal performance of the main house.
Key System Features
Media Filtration
All our systems include media filters, allowing for smaller, multiple returns instead of one large return with a basic 1-inch filter.
Zoning for Comfort
We strongly recommend zoning for raised ranch homes. Living spaces over unconditioned garages have completely different heating and cooling needs than spaces over conditioned basements. Without zoning, you’ll never achieve balanced comfort throughout the house.
What We Don’t Recommend
Individual Mini-Splits in Every Bedroom
This approach is inefficient and provides poor dehumidification during summer months.Mixed Systems
Some contractors suggest mini-split heads in main living spaces with ducted systems only in bedrooms. However, if you have accessible attic space, installing ductwork throughout the upper level is the more sensible solution.
Investment Range
The cost to upgrade a raised ranch home to an efficient heat pump system typically ranges from $28,000 to $36,000, depending on your home’s specific needs and existing conditions.
This investment includes proper insulation upgrades, a ducted system for the upper level with new ductwork, mini-split heads for the lower level, media filtration, and zoning controls for optimal comfort and efficiency.
Keep in mind that NYSERDA rebates may be available to help offset your investment.
