Frequently Asked Questions & Expert Guidance

Q: Do heat pumps work in freezing temperatures?

A: Modern cold-climate inverter heat pumps maintain up to 100% heating capacity down to 5°F and operate efficiently down to -15°F outdoor ambient temperatures.

Q: What is the difference between SEER2 and HSPF2?

A: SEER2 measures summer cooling efficiency, while HSPF2 measures winter heating efficiency. Higher numbers indicate lower monthly electrical power consumption.

Mini Split Selection Realities: Sizing & Refrigerant Changes

Choosing the right mini split system requires looking past generic "square footage" guidelines. Standard internet sizing charts fail to account for regional insulation values and extreme low-ambient conditions.

The Refrigerant Transition: As of 2025–2026 EPA mandates, older R-410A systems are being phased out in favor of low-GWP alternatives like R-454B and R-32. MSSD strictly catalogs equipment compliance status across every tier to safeguard your long-term parts availability.
The Real Cost of Shipping: Unlike standard e-commerce checkouts, comprehensive mini split systems involve line sets, brackets, and line covers that require secure freight delivery. Every MSSD price reflects our complete wholesale kit distribution framework with liftgate delivery options accounted for transparently.
