Troy Weather and HVAC Load
NOAA's 1991-2020 climate normals put Troy at 6,006 heating degree days and 895 cooling degree days per year. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. Count on roughly 131 nights below 32°F and 13 afternoons past 90°F in a typical year. Snowfall averages about 59 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.
| Heating degree days / year | 6,006 |
|---|---|
| Cooling degree days / year | 895 |
| Nights at or below 32°F | 131 |
| Days above 90°F | 13 |
| Average low / high | 40.8°F / 61°F |
Troy Housing Stock
Census figures put the median build year in Troy at 1938, so a typical house here has about 88 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 36.8% of occupied homes, roughly 7,800 households. The median home value is $192,500, and median household income is $57,688. We use both figures to adjust labor and pricing for this page.
Rensselaer County had 4 hail days and 43 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.
When It Makes Sense
- The AC is 12 to 15 years old or more
- Summer electric bills keep going up
- It has had more than one refrigerant leak
- It still runs on R-22 refrigerant
What Moves the Price
- Tonnage, based on house size and local climate
- Whether the coil and line set also need replacing
- SEER2 rating and whether the compressor is single-stage or variable-speed
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- Electrical work such as a new disconnect, breaker or wiring
We lowered the national figures about 17% for Troy using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Removing the old condenser and coil
- The new condenser, coil and, if needed, line set
- Refrigerant charge and a leak test
- The electrical disconnect and wiring
- Startup, an airflow check and warranty registration
New York Permits, Efficiency Rules and Rebates
New York falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Plan on a mechanical permit for most replacements in Troy; the contractor normally pulls it. Before you sign, ask each bidder for their New York license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Fall and early spring installs often come with better pricing and shorter waits.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.

Between late spring and early fall. Troy averages 131 freezing nights a year, and heating calls spike from November through February.
What size AC do I need?
