When buying or selling a home, most people focus on location, layout, and curb appeal. But there’s another major factor that can impact comfort, costs, and even the sale price: the HVAC (Heating, Ventilation, and Air Conditioning) system.
For Buyers: What to Look For
1. Age and Condition – Ask how old the furnace, air conditioner, or heat pump is. Most systems last 15-25 years with proper maintenance, and older units may soon need replacement. Based on the unit(s) this could cost between $4000, up to $20,000 or more to replace.
2. Efficiency Ratings – Check for energy-efficient models (look for SEER or AFUE ratings). Higher efficiency means lower utility bills over time. This may not be a “game-changer” with regards to buying the home but should be a consideration for how much it will cost to heat and cool the home in the next few years.
3. Maintenance History – Request service records. A well-maintained system often indicates fewer surprises down the road. It’s easy to say, but a poorly maintained unit could reduce the life of the unit by as much as 50%, or more.
4. Comfort and Air Quality – During showings, notice if rooms heat and cool evenly. Poor airflow or humidity issues may signal underlying problems. Take a moment to look at the duct work in the basement. Is it original to the current furnace or did they replace the furnace but left the duct work as it was. Proper duct work not only improves the efficiencies of the HVAC system but can help to better balance the airflow throughout the home.
For Sellers: How to Prepare
1. Get a Tune-Up – A professional inspection and cleaning can reassure buyers and prevent issues from showing up on an inspection report. Make sure your HVAC company leaves a sticker on the unit showing the last inspection. This will catch a buyer’s eye to know the unit(s) were recently serviced.
2. Highlight Upgrades – If you’ve installed a high-efficiency system or added features like smart thermostats, make sure they’re mentioned in your listing.
3. Be Honest About Age – If your system is older but functional, be prepared to provide documentation of regular maintenance to show it’s been cared for.
4. Manuals – If you have the original manuals and warranty paperwork from the manufacturer, have them in a binder or folder to share with the new homeowners.
5. Referrals – This one may not be top of mind, but we would also encourage you to add your HVAC company’s contact information in the binder. This is the team that’s worked on these units and will have the best understanding of what’s needed to keep the equipment operating at its best. Often they have the warranty information on file and related paperwork.
Why It Matters
A reliable HVAC system is more than just a comfort feature—it can affect utility costs, long-term expenses, and even negotiations during the sale. Buyers gain peace of mind knowing they won’t face an unexpected replacement, and sellers can use a well-maintained system as a selling point.
