Frequently Asked Questions

• How do I choose the right tonnage condenser to match my existing air handler?

  Match the condenser’s nominal tonnage to the air handler/coil rating. Verify an AHRI-matched pair, correct TXV/orifice, and airflow (~400 CFM per ton) with a qualified contractor.

• What SEER2 rating should I select for my climate and budget?

  14.3-16.2 SEER2 suits tighter budgets or mild climates; 17.2-19 maximizes savings in hot regions or for high runtime homes. Balance utility rates, upfront cost, and rebates.

• What is the difference between straight cool condensers and heat pump condensers?

  Straight cool handles cooling only, paired with electric heat strips or a furnace for heat. Heat pumps cool and heat via a reversing valve, reducing winter electric costs.

• Can I mix R-410A equipment with R-32 or R-454B systems?

  No. R-410A, R-32, and R-454B are not cross-compatible. If switching, replace or verify compatible indoor coil, metering device, and often the line set per manufacturer.

• Do these condensers require a licensed contractor for installation and charging?

  Yes. EPA 608 certification is required for refrigerant handling. Proper evacuation, charging by weight, and setup (subcooling/superheat) ensure performance and warranty compliance.

• Are these units suitable for light commercial applications?

  Yes, many 3-5 ton models serve small offices, retail, and multi-family common areas. Confirm load requirements, ventilation, and electrical specs for your site.

• How do I verify compatibility with my existing indoor coil and line set?

  Use the model numbers to find an AHRI match. Check refrigerant type, coil tonnage, TXV/orifice, and line set size/length; flush or replace lines as required.

• What are the pros and cons of switching from straight cool with electric heat to a heat pump?

  Pros: lower heating bills, steady comfort, rebates in many areas. Cons: needs a compatible thermostat/heat kit and has defrost cycles; add auxiliary heat for very cold climates.

• Can I reuse my existing thermostat and breaker?

  Often yes for straight cool. Heat pumps need a heat pump-capable thermostat (with O/B) and proper aux heat wiring. Size breaker/wiring to MCA/MOP on the nameplate.

• What maintenance helps a condenser last longer?

  Keep coil fins clean, maintain 18-24 inches of clearance, replace filters regularly, and schedule annual tune-ups to verify refrigerant charge and electrical components.
