Takes about a minute. No obligation.
A contractor quoting a central AC install in Teller County has to ask what the system will actually be asked to do. Homes in Teller County, CO have essentially no cooling season — no month of the year is warm enough to call for it. The compressor, the condenser fan, and the contactor sit idle through the entire calendar. Long idle periods let refrigerant migrate, seals dry out, and electrical contacts corrode without the cycling that would surface those faults early. When a compressor fails here, the cause is rarely accumulated runtime. Proper installation and correct sizing still matter, because a poorly charged or undersized system will fail faster even on rare use.
Ductwork sized for an older heating setup carries different airflow requirements than a new central AC unit places on it. Half the homes in Teller County, Colorado were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in a house from that era has to assess what the existing duct runs can actually move before the equipment choice means anything. Panels from the same period are worth the same check: a modern central unit draws more than many of those service panels were wired to supply. The equipment selection comes after that groundwork, not before.
What a Central AC Installation Covers
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet and is the indoor half of what gets purchased and placed.
The refrigerant lines run between those two units through the wall or a chase, and the thermostat mounts on an interior wall where it reads the home's temperature and tells the system when to run. Each of these pieces is part of what a contractor sources, positions, and connects during the installation.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house.

What HVAC Installation Looks Like in Teller County
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
Severe Weather Events in Teller County
Weather puts a measurable load on cooling equipment, and that load varies by location. How hard the climate pushes here shapes what a central AC system needs to handle and how often it has to handle it.
