AC Installation in
Lewisville, TX

When to Replace Your Lewisville AC

Most Lewisville AC systems installed before 2010 are 13 SEER R-22 units approaching or past end of service life. Replace if your system is 12+ years old, uses R-22 refrigerant (production phased out in 2020), has had two or more major repairs in a season, or your energy bills have climbed without usage changes. See our blog post on repair vs. replacement for the full decision framework.

Manual J Load Calculation - No Square-Footage Guesses

Lewisville housing stock spans 1970s ranches in Old Town, 1990s subdivisions in Vista Ridge, and 2010s-2020s tract construction in Garden Ridge and Hebron-side neighborhoods. Each era has different ductwork sizing, insulation levels, and window-to-floor-area ratios. We run an ACCA Manual J load calculation on every install to size the system correctly. Oversizing leads to short-cycling, poor humidity control, and premature compressor wear. Undersizing means the system runs constantly and cannot keep up.

Armstrong Air Systems We Install

As an Armstrong Air ProTeam dealer (see our ProTeam page), we install the full Pro Series lineup:

• Pro Series 4SCU13LE / 4SCU16LE - Single-stage AC at 13 SEER2 and 16 SEER2. Budget-tier replacements.
• Pro Series 4SCU18TE - Two-stage AC. Better humidity control on 3-ton+ systems.
• Pro Series 4SCU20LX - Variable-speed at 20+ SEER2. Best for two-story Lewisville homes with temperature differential issues.

Daikin Systems for Lewisville Lakeside Homes

For homes around Lake Lewisville and Garden Ridge - where humidity stays elevated and shoulder-season operation matters - Daikin Fit and Atmosphera inverter systems deliver tighter humidity control than single-stage units. We install the full Daikin residential split-system lineup.

Samsung Mini-Split for Additions, Garages, and Detached Studios

Lewisville's older Old Town neighborhoods have add-on rooms and converted garages that never tied into the central duct system. Samsung WindFree mini-split is the typical fix. See our mini-split installation page for single-zone and multi-zone configurations.
