What Homebuyers Should Know About HVAC Before Closing

Buying a home in Boone or the High Country? The HVAC system is one of the most expensive components you'll inherit — a new heat pump or furnace can cost $5,000-$12,000+. Before you close, here's what every homebuyers should know about the HVAC system.

Check the Age of the Equipment

HVAC equipment has a finite lifespan:

• Heat pumps: 10-15 years
• Furnaces: 15-20 years
• Air conditioners: 10-15 years
• Ductless mini-splits: 12-15 years

Ask the seller for installation records or check the manufacturer's data plate on the unit — it usually has a manufacture date. If the system is near the end of its life, budget for replacement or negotiate the price.

Look for Efficiency Ratings

Check the SEER (cooling) and HSPF (heating) ratings on the equipment. Higher is better:

• SEER 16+: Good efficiency
• SEER 20+: High efficiency
• HSPF 9+: Good heating efficiency for heat pumps

Older, low-efficiency systems will cost significantly more to operate. In Boone's climate, where your HVAC runs year-round, efficiency matters — a SEER 13 system vs. SEER 20 can mean hundreds of dollars difference annually.

Inspect the Outdoor Unit

Walk outside and examine the heat pump or AC condenser:

• Is it level on its pad? A tilted unit strains the compressor
• Are the fins damaged or bent? This reduces airflow and efficiency
• Is there rust or corrosion? Signs of neglected maintenance
• Is it clear of vegetation and debris? Should have 2+ feet of clearance
• Is it elevated above snow line? Critical for mountain homes

Test Both Heating and Cooling

During your inspection period, test both modes:

• Set the thermostat to cooling and wait 10 minutes — does cool air come from all vents?
• Set it to heating and verify warm air reaches every room
• Listen for unusual noises — grinding, squealing, or banging indicate problems
• Check that the thermostat is responsive and programmable

In Boone's climate, you need both heating and cooling to work reliably. A system that cools fine but struggles in heating mode is a red flag for heat pump issues.

Ask About Maintenance History

A well-maintained system lasts longer and performs better. Ask the seller:

• When was the last professional maintenance?
• Are there records of repairs or replacements?
• Has the system had any refrigerant leaks or compressor issues?
• What size filter does it use, and where are they changed?

No maintenance history is a warning sign — the system may have hidden issues.

Homebuyers: Get a Professional HVAC Inspection

Home inspectors check whether the HVAC turns on, but they typically don't evaluate refrigerant levels, coil condition, ductwork integrity, or heating capacity. For a home purchase in Boone, we recommend a dedicated HVAC inspection by a licensed professional. Our team will assess the system's condition, estimate remaining life, and flag any issues — so you can negotiate repairs or budget for replacement before you move in.
