Residential HVAC Buyer's Guide
Current 2026 market prices and honest ratings to help you choose the right system for your Texas home.
Replacing or installing a new HVAC system is one of the biggest home investments you'll make. In Texas, where summers routinely hit 105°F, choosing the right system — and the right installer — directly impacts your comfort and your electric bill for the next 15–20 years.
SEER2 Rating: Look for at least 15 SEER2. Texas homes often benefit from 18+ SEER2 given our long cooling seasons.
Variable Speed: Variable-speed compressors cost more upfront but reduce humidity far better — critical in Central Texas.
Sizing matters: An oversized unit won't dehumidify properly. Insist on a Manual J load calculation before any system is sized.
