Overview Of Day & Night Heat Pumps
Day & Night is a subsidiary of International Comfort Products (ICP), itself owned by Carrier Global Corporation. Known for value and robust engineering, Day & Night offers a broad range of heat pump systems catering to different regions and climates across the U.S. Their equipment closely matches models from Carrier and Bryant, using proven designs and similar parts, but often at more attractive price points.
All Day & Night heat pumps are ENERGY STAR® certified, and many models qualify for federal, state, or local rebates—making them popular among budget-conscious Americans seeking energy savings.
Day & Night Heat Pump Series And Models
Day & Night offers three primary lines of heat pumps: the premium Ion™ Series, enhanced QuietComfort® Series, and economical Performance Series. Below is a breakdown of their core offerings as of 2025:
Series | Model Examples | SEER2 | HSPF2 | Compressor Type | Best For |
---|---|---|---|---|---|
Ion™ | HVA9, HVA7 | Up to 19 | 11 | Variable-speed, Two-stage | Maximum efficiency, comfort |
QuietComfort® | DLC6, DLCSHB | Up to 17 | Up to 9.5 | Two-stage | Quieter, consistent comfort |

Key Features And Technologies
Ion System Control: The Ion Series uses Day & Night’s smart communicating system, enabling advanced diagnostics, Wi-Fi control, and precise performance monitoring. This system supports zoning, easy troubleshooting, and integration with smart home platforms.
Variable-Speed Compressors: Premium models use inverter-driven compressors for modulating output. This results in lower energy bills, quieter operation, and more stable temperatures—ideal for year-round comfort.
Two-Stage Technology: Select units run most of the time at partial capacity, improving efficiency and humidity control. The system can shift to high-output mode only during temperature extremes.
Enhanced Dehumidification: Ion and QuietComfort series emphasize moisture removal for comfort in humid climates, reducing mold risk and improving indoor air quality.
WeatherArmor™ Protection: All outdoor units feature heavy-duty coil guards, baked-on powder-paint, and reinforced cabinets for rust resistance and longevity during harsh weather.
No Hassle Replacement Limited Warranty: Many Day & Night models are covered by a “No Hassle” replacement warranty, providing full-unit replacement if the compressor or coil fails within the early years of ownership.
Energy Efficiency: SEER2 & HSPF2 Ratings
Energy efficiency is a crucial selling point of Day & Night heat pumps. SEER2 (Seasonal Energy Efficiency Ratio 2) and HSPF2 (Heating Seasonal Performance Factor 2) measure cooling and heating efficiency using updated 2023 federal standards.
- Ion HVA9: Up to 19 SEER2, 11 HSPF2 (among highest for residential heat pumps)
- QuietComfort DLC6: Up to 17 SEER2, 9.5 HSPF2
- Performance N4H6: 15.2 SEER2, 8.1 HSPF2 (meets minimum federal guidelines in all climates)
Compared with standard air conditioners or older heat pumps, upgrading to a Day & Night unit can provide 20%–50% energy savings, depending on current equipment age and home insulation quality.
Noise Levels And Indoor Comfort
Homeowners appreciate quieter operation—especially in bedrooms or home offices. Day & Night’s advanced models use sound-absorbing cabinets, variable-speed fans, and two-stage compressors to minimize noise.
- Ion Series: As low as 56 dB, comparable to a quiet conversation
- QuietComfort Series: 66–69 dB (quieter than many competitors)
- Performance Series: 70+ dB (standard for mid-range units)
Outdoor noise impact is further reduced by WeatherArmor Ultra™ housing, allowing Day & Night to compete with premium brands on quietness.
Durability And Build Quality
Day & Night heat pumps are manufactured with galvanized steel construction, powder-coated finishes, and durable coil protection to prevent rust, damage, and wear—even in challenging climates subject to hail, salt air, or high UV exposure.
Because Day & Night shares engineering platforms with Carrier and Bryant, homeowners benefit from parts compatibility and access to a broad nationwide dealer network for service. This helps ensure long-term reliability and easier maintenance.
Installation And Sizing Considerations
Proper installation is essential for heat pump efficiency and lifespan. Day & Night’s dealer locator system connects users with licensed, factory-authorized contractors nationwide.
Heat pump sizing depends on climate, insulation, square footage, and ductwork. Oversized units cycle inefficiently; undersized systems struggle in winter. A professional “Manual J” load calculation helps determine the ideal model from the Ion, QuietComfort, or Performance line based on the home profile.
Warranty And Support
Day & Night stands out for robust warranty coverage on registered equipment:
- 10-Year Limited Parts Warranty on compressors, coil, and key moving parts
- No Hassle Replacement™ Limited Warranty (1–10 years, model-dependent) for full unit replacement on select failures
- Specific labor coverage offered by many authorized installers as an additional protection option
Timely online registration is required to receive full 10-year coverage. Otherwise, base warranties may only extend five years.
Pricing And Value Comparison
Day & Night heat pumps are competitively priced for Americans seeking value, with the following averages for full-fledged installation:
- Entry Level (Performance Series): $5,000–$7,000 installed
- Mid-Range (QuietComfort Series): $7,000–$8,500 installed
- Premium (Ion Series): $8,500–$10,000+ installed
Prices vary by region, model, unit size, ductwork needs, and any home electrical upgrades. Federal tax credits (up to $2,000) and state incentives may offset upfront investments.
Compared with Carrier, Lennox, Trane, or American Standard, Day & Night provides similar efficiency and warranty—in many cases, at $1,000–$2,500 less installed.

- Replace or clean air filters every 1–3 months
- Schedule professional tune-ups annually (including refrigerant checks and coil cleaning)
- Keep outdoor units free of debris, snow, and soil buildup
- Register equipment online soon after installation
- Monitor alerts and status through smart thermostats (Ion Series)
