SEER (Seasonal Energy Efficiency Ratio) measures how efficient an AC or heat pump is — higher is better. As of 2023, the DOE requires SEER2 (a tougher test). Minimum in Texas is 15 SEER2. Most Houston homeowners hit the best payback at 16–18 SEER2; anything higher rarely pays back through energy savings alone unless you plan to stay 10+ years.

Not a square-footage rule of thumb — that's how homes get oversized systems that short-cycle, run humid, and die early. We size based on your home's tonnage needs, ductwork, insulation, and how the existing system has performed, and we'll walk you through the recommendation before you commit.

A heat pump moves heat instead of generating it, so it heats and cools with one unit. In Houston's mild winters, heat pumps are extremely efficient and pair well with a gas or electric backup. They also qualify typically for the largest federal tax credits and utility rebates.

Yes — a mini split is a wall- or ceiling-mounted indoor unit paired to an outdoor condenser that both heats and cools. They're ideal for garage conversions, sunrooms, ADUs, and rooms that never got comfortable. We install and service LG and Ruud mini splits.
