The real payoff of a new system is years of lower bills. Moving from an aging, low-efficiency unit to a modern high-efficiency one can trim a few hundred dollars a year off heating and cooling across a long season.
Spot a fair quote in Evans
A typical system replacement here runs $7,900–$12,800. A fair quote starts with a Manual J load calculation. Be wary of anyone who sizes a system off square footage alone or pushes a same-day signature.
- Ask for the Manual J load calc, not a rule-of-thumb size.
- Confirm the SEER2/AFUE rating and that it's A2L-compliant.
- Get the labor warranty and rebate paperwork in writing.
What changes your price
- System type & efficiency. Heat pump vs dual-fuel and the SEER2/HSPF2 tier move the price the most.
- Ductwork condition. Leaky or undersized ducts may need sealing or replacement to hit rated performance.
- 2025 refrigerant change. New systems use A2L refrigerant (R-454B/R-32) and run 10–20% higher than pre-2025 equipment.
- Proper sizing (Manual J). A load calculation prevents the costly mistake of oversizing or undersizing the system.

Why it matters
Why it pays to do it right
Comfort in the toughest weather
An undersized or failing system can't keep up when the weather turns extreme, in deep cold or relentless heat. Right-sized equipment holds temperature without short-cycling.
The repair-vs-replace tipping point
Once a system is 12+ years old and out of warranty, a major repair often costs more than it buys, especially with old-refrigerant prices climbing.
Lower, steadier energy bills
Jumping from an aging unit to a high-efficiency one can cut heating and cooling costs meaningfully over a long season.
Cleaner, healthier air
New systems filter and dehumidify better, which matters when homes are sealed up for months of winter.
Local conditions
HVAC in Greeley
Heating and cooling both matter in Evans: cold northeastern Colorado winters with design lows near -10°F demand a reliable heating system, and summer highs in the mid-to-upper 90s on the exposed high plains put a real load on central AC from June through August. Wind amplifies both the heating and cooling demand.
Design winter low
~-10°F
Cold northeastern Colorado winters demand a properly rated heating system; dual-fuel setups pairing a cold-climate heat pump with gas backup are common across Greeley.
Design summer high
~96°F
Hot, dry, and exposed high-plains summers put a significant load on AC; a properly sized system is essential for comfort and efficiency.
High-wind exposure
Frequent
Northeastern Colorado plains wind increases infiltration and heating load; a tight home envelope and well-sealed ductwork reduce energy waste substantially.
Incentives & rebates
Xcel Energy offers efficiency rebates on qualifying heat pumps and high-efficiency central AC through its Colorado energy-efficiency programs. The federal 25C heat-pump tax credit expired at the end of 2025, so for 2026 those Xcel rebates plus efficient-equipment financing carry the upfront savings in Evans, and request a Manual J load calculation before any system is sized, Greeley's wide temperature swings, altitude, and exposed plains location all affect proper equipment selection.
Permits
Mechanical permits are required for full HVAC changeouts in Evans.
FAQ
HVAC questions, answered for Evans
Does a heat pump work in Evans's cold winters?
Yes, with the right equipment. A cold-climate heat pump handles most Evans heating days efficiently, but because lows can reach -10°F on the northeastern Colorado plains, a dual-fuel setup with gas backup is the most common and reliable approach.
Are there rebates for HVAC in Greeley?
Yes. Xcel Energy offers efficiency rebates on qualifying heat pumps and high-efficiency central AC. The federal 25C credit expired at the end of 2025, so for 2026 those Xcel rebates carry the savings on a qualifying changeout in Evans.
How often should I service my HVAC in Evans?
Annual tune-ups are recommended, a spring check on the cooling system before summer and a fall check on heating before winter. After any hail event, inspect the outdoor condenser unit for fin damage that can cut efficiency.
Do I need a permit for a new HVAC system in Evans?
Yes, mechanical permits are required for full system changeouts in Evans. A licensed installer typically pulls the permit and schedules the required inspection.
