1.5 Ton

A 1.5-ton (approximately 18,000 BTU) heat pump split system is ideal for small homes, apartments, or dedicated zones. Homeowners, DIY capable homeowners, licensed contractors, and property managers choose these systems for whole-home heating and cooling, like-for-like replacements, and code-compliant upgrades. Professional installation is required for safety, warranty, and performance.

Our selection spans SEER2 14.3, 14.5, and 15.2 ratings to meet regional standards while keeping costs down. Models use modern refrigerants including R-32, R-410A, and R-454B, so you can align refrigerant strategy with your project. Outdoor units pair with properly sized indoor air handlers in 14", 17.5", and 18" cabinet widths to fit existing closets and duct openings. Most systems work with standard 24V heat pump thermostats. Expect budget-friendly pricing from $2,540 to $4,322.

When upgrading an older system, match tonnage, airflow, and refrigerant, and verify line set size and cleanliness; R-32 and R-454B conversions from R-410A often require component changes and a precise evacuation and charge. Most 1.5-ton systems run on 208/230V with dedicated breakers-always confirm MCA/MOP on the nameplate. Proper sizing (Manual J), duct verification, and pro startup ensure quiet, efficient operation.

Frequently Asked Questions

  • What size home or square footage is a 1.5-ton heat pump system suitable for?

    Typically 600-900 sq ft in average climates with good insulation. Always confirm with a Manual J load calculation.

  • What is the difference between R-32, R-410A, and R-454B refrigerants for these systems?

    R-32 and R-454B offer lower GWP than R-410A. Components and oils are different-do not mix. Use equipment matched to the refrigerant.

  • Are these 14.3-15.2 SEER2 systems compliant with current efficiency standards in my region?

    Yes. 14.3 SEER2 meets the federal minimum for heat pumps. Check local or utility program requirements for any higher targets.

  • Do these split heat pump systems require a licensed contractor for installation and warranty coverage?

    Yes. Professional installation is required for refrigerant handling, code compliance, proper startup, and to maintain warranties.

  • How do I match the correct air handler (cabinet width 14-18 inches) with a 1.5-ton outdoor unit?

    Select a 1.5-ton, same-refrigerant air handler/coil. Choose 14", 17.5", or 18" cabinet width to fit the space and duct, and verify airflow ~600 CFM.

  • What thermostat or controls are compatible with these 1.5-ton split heat pump systems?

    Most use standard 24V heat pump thermostats (O/B reversing valve, aux heat if used). Avoid brand-specific communicating stats unless required.

  • Can I replace an older R-410A system with an R-32 or R-454B unit without changing lineset or components?

    Sometimes the lineset can be reused if correctly sized and clean, but coils/valves and filter-driers must match. Follow manufacturer guidance.

  • What are the electrical and breaker requirements for a 1.5-ton heat pump system?

    Commonly 208/230V single-phase. Size breakers per the unit’s MOP; air handler often needs a separate circuit. Verify on data plates.

  • Will a 1.5-ton heat pump provide heat in colder weather?

    Yes. Capacity declines as temperatures drop; auxiliary electric heat or another backup source may be needed in very cold climates.

  • What accessories should I plan for with a new installation?

    Equipment pad, disconnect, whip, properly sized lineset, filter-drier, thermostat, drain tubing, and optional heat strips for auxiliary heat.
