By Keller Williams NYC
Energy efficiency in New York looks different depending on what kind of home you own, and we work with clients across the full range every day. Some of our clients own houses with full control over insulation, heating, and windows, while others own co-ops or condos where building rules shape what upgrades are possible. We want to help you understand what actually applies to your situation before you spend money on the wrong project. This guide walks through the upgrades worth prioritizing based on your property type, along with a few habits and programs that can help offset the cost.
Key Takeaways
- Energy efficiency upgrades differ significantly for houses versus co-ops and condos
- Homeowners have more flexibility than co-op or condo owners, who often need board approval for larger changes
- Utility and state programs can help offset the cost of certain upgrades
- Energy efficient improvements can make a real difference when it comes time to sell
Know Your Property Type Before You Start
New York includes a wide range of housing, from detached houses to co-ops and condos, and each comes with a different set of options. Owners of houses generally have the most flexibility since they control the full structure, from the roof down to the boiler. Co-op and condo owners work within building rules and often need approval before making changes that affect shared systems like heating, water, or windows.
Before spending money on any upgrade, it helps to understand exactly what you own and what you don't. A house owner can replace a boiler outright, while a condo owner may only be able to control what happens inside their own four walls. Taking the time to sort this out first can save you from proposing a change that a board will not approve, or from overlooking something you actually have full control over.

Questions To Ask Before Any Project
- Do you own the structure outright, or are shared systems like heating and windows managed by a building or board
- Does your building already have an energy efficiency initiative underway that you can join or benefit from
- Are you making changes to sell soon, or investing in long-term savings
Upgrades Worth Prioritizing If You Own a House
If you own a house, you have the most control over meaningful, whole-property upgrades. These tend to have the biggest impact on comfort and on your monthly energy bill, especially in older homes that were built before modern efficiency standards existed.
Many of the houses we work with have not been touched structurally in decades, which means there is often low-hanging fruit available before you get to anything expensive.

Where To Start
- Add insulation to the attic and basement, which is one of the most cost-effective ways to reduce heat loss in older homes
- Replace older single-pane windows with double-pane or triple-pane options
- Upgrade to a high-efficiency boiler or heat pump, especially if your current system runs on oil
- Seal air leaks around doors, pipes, and window frames, which is often overlooked but makes a real difference
- Have a professional energy audit done first, so you know which upgrades will actually pay off
Upgrades Worth Prioritizing If You Own a Co-op or Condo
If you own a co-op or condo, larger systems like heating and windows are usually managed at the building level. That still leaves meaningful changes you can make within your own unit, and many of them cost far less than a house-level renovation.
We often remind clients that small, unit-level changes add up over time, and they are worth making even if you plan to move again in a few years.

What You Can Control
- Install a smart thermostat, which can noticeably reduce heating and cooling costs even in a single unit
- Switch to LED lighting throughout the apartment
- Use thermal curtains or window inserts to reduce drafts without needing board approval
- Upgrade to ENERGY STAR certified appliances when it's time to replace a refrigerator, dishwasher, or washer and dryer
- Ask your board whether the building has any planned upgrades to boilers, windows, or common systems
Programs and Incentives That Help Offset the Cost
Several programs exist to help make efficiency upgrades more affordable, though which ones apply to you depends on your property type and utility provider. It's worth checking eligibility before assuming a program covers your specific situation.
NYSERDA, the New York State Energy Research and Development Authority, offers home energy assessments and rebates that individual homeowners across the state can apply for directly. Utility providers like Con Edison and National Grid also offer their own rebate programs for insulation, heating equipment, and appliances, though the specific offerings depend on which company services your area. Larger co-op and condo buildings may also be able to work with programs like NYC Accelerator, which is primarily geared toward helping bigger buildings identify efficiency upgrades and meet the city's emissions requirements, so this is more relevant to boards than individual unit owners.

A Few Places To Start Looking
- NYSERDA's home energy assessments and rebate programs
- Rebates through your utility provider, whether that's Con Edison, National Grid, or another company
- NYC Accelerator, if you sit on a co-op or condo board looking into building-wide upgrades
Simple Habits That Add Up
Not every improvement requires a renovation or a big purchase. Some of the most effective changes are habits you can start today, regardless of what kind of home you own.
Everyday Changes Worth Making
- Set your thermostat a few degrees lower in winter and higher in summer when you're not home
- Use ceiling fans or portable fans to reduce reliance on air conditioning during shoulder seasons
- Unplug electronics and chargers when they're not in use, since many devices draw power even when idle
- Wash clothes in cold water when possible, which reduces the energy your washer uses
How Energy Efficiency Affects Resale Value
We consistently see buyers respond well to homes with visible efficiency upgrades, whether that's a house with new insulation or a unit with updated appliances and smart home features. Lower utility costs are a real selling point, and they can help a property stand out in a competitive market.
Buyers today are more likely to ask about these details upfront than they were a few years ago, which means sellers who have already made improvements often have an easier time positioning their home. We recommend keeping records of any upgrades you make, including receipts and installation dates, since this information helps us tell a clear story to buyers when it comes time to list.

What Buyers Tend To Ask About Most
- Recent HVAC or boiler replacements, since these represent a significant future expense if not already addressed
- The age and condition of windows
- Whether appliances are ENERGY STAR rated, which buyers increasingly view as a baseline expectation
Frequently Asked Questions
Is it worth upgrading insulation in an older house?
Yes, insulation is often the most cost-effective improvement for older houses, since it reduces heat loss and lowers heating costs significantly. Many older houses were built before modern insulation standards existed. We often point clients to NYSERDA's home energy assessment as a starting point.
Can I make energy efficient upgrades if I live in a co-op?
Yes, though most upgrades happen at the unit level rather than affecting shared building systems. Smart thermostats, LED lighting, and ENERGY STAR appliances are all changes you can make on your own. Larger changes like window replacement usually require board approval.
Do energy efficient upgrades actually help when selling in New York?
We consistently see buyers respond positively to homes with visible efficiency improvements, whether that's a renovated heating system or updated appliances. These upgrades can shorten time on market and support a stronger asking price. It's one of the details we highlight when marketing a listing.
