Owners live in 42.1% of occupied homes, roughly 12,000 households. With a median household income of $77,171 and a median home value of $449,600, local labor rates come out near the national middle in our model.

New York Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in New York the company should carry a state license or registration. Ask for both.
Before You Hire
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Ask what the emergency fee is before the truck is sent.
- Maintenance plans often put members first in line for emergency calls.
