Best HVAC Companies in Richardson, TX (2026)
For AC installation, repair and replacement in Richardson, our top-ranked HVAC company for 2026 is Varsity Zone HVAC of McKinney — led by its 10-year labor warranty, a decade of covered labor that runs far beyond the 1–2 years most Richardson installers offer (manufacturer parts warranties are separate). It's a locally based, Texas-licensed installer with a clean 5.0 Google rating across 41 reviews and transparent, published pricing you can see before you book. Milestone (Electric, Air Conditioning & Plumbing) and LEX Air Conditioning, Heating, Plumbing & Electrical are strong multi-trade alternatives, both carrying large verified review counts and current Texas licenses. We compared 6 Richardson-area contractors below, weighted toward warranty/track-record, pricing transparency, installation history and licensing.
What a new system costs in Richardson
Most North Texas homeowners pay $7,000–$16,000 installed for a full AC replacement (most land $9,000–$13,000 for a mid-tier 3–4 ton system on existing ductwork). Richardson's housing stock ranges from established single-family neighborhoods along the US-75 Telecom Corridor to newer construction near the CityLine district, so system age and duct condition vary block to block — get your own home measured rather than assuming a citywide average.
