Frequently Asked Questions

How do I choose between the new SEER2 ratings?

As of 2023 and updated through 2026, the industry has shifted from SEER to SEER2 (Seasonal Energy Efficiency Ratio 2). This newer testing standard more accurately reflects real-world “static pressure” (how hard the unit has to push air through your vents). While a higher SEER2 rating—like a 18 or 20—costs more upfront, these units often feature Inverter Technology, allowing the compressor to run at variable speeds rather than just “on” or “off.” This results in significantly better humidity control and lower monthly electricity bills.

Should I replace my indoor evaporator coil at the same time as the outdoor condenser?

Yes, this is highly recommended for a “matched system.” Modern air conditioners use R-454B or R-32 refrigerants, which operate at different pressures than the older R-410A systems. If you try to pair a new high-efficiency outdoor unit with an old, dirty indoor coil, the system will not reach its rated efficiency and will likely suffer from premature compressor failure. Furthermore, a new indoor coil features a Thermal Expansion Valve (TXV) specifically calibrated to the new outdoor unit’s refrigerant flow, ensuring optimal cooling and dehumidification.

Why is a "Manual J" load calculation better than using my old AC’s size?

Technology and home insulation have improved over the decades. If your home has new windows or better attic insulation, your old 3-ton unit might now be oversized. An oversized AC is actually worse than an undersized one; it will “short-cycle,” cooling the air so fast that it never has time to remove the humidity, leaving your home feeling “cold and clammy.” A Manual J calculation takes into account your home’s orientation to the sun, wall thickness, and window types to determine the exact BTU capacity required for a comfortable, dry environment.
