AC Installation & Replacement in Garland TX & DFW

New AC Installation & System Replacement

Whether your current system has reached the end of its life or you're ready to upgrade to a more efficient unit, Expedition HVAC makes the process straightforward. We'll help you choose the right system for your home's square footage, your budget, and the Texas climate — without steering you toward a more expensive option than you need.

Our technicians are paid salary, not commission, so there's no financial incentive to oversell you on a system. We'll give you honest recommendations based on your home's actual needs.

What's Included in Every AC Installation

• Full load calculation to size your system correctly
• Removal and disposal of your old unit

When to Replace vs. Repair Your AC in DFW

Dallas-Fort Worth's climate is unusually demanding on residential AC systems. Because temperatures regularly climb above 100°F and cooling season runs from May well into October, DFW homeowners run their air conditioners 6 or more months per year — far more than in most other parts of the country. That extra annual runtime accumulates quickly, and even well-maintained systems typically reach the end of their useful life in 12–17 years here, compared to the 15–20 year lifespan manufacturers quote for cooler climates. Regular maintenance extends the window, but eventually the math shifts: repairs become more frequent, efficiency drops, and the cost to keep the old system going starts to approach — or exceed — what a new system would cost.

The clearest signs it's time to replace rather than repair: your system is 12 or more years old, a repair estimate exceeds roughly half the cost of a new system, your electricity bills have climbed noticeably without a change in usage, your system uses R-22 refrigerant (which is no longer manufactured and now expensive to source), or you're calling for repairs more than once a season. If you're not sure which way the math points, Expedition HVAC's salary-based technicians will lay out both options honestly — what a repair would cost, what a replacement would cost, and which makes more financial sense for your situation. There's no commission incentive pushing our techs toward the pricier path.

Choosing the Right AC System for Your DFW Home

Sizing is the most important — and most commonly mishandled — part of an AC installation. An oversized unit cools the home too quickly without running long enough to pull humidity out of the air, then short-cycles on and off repeatedly, wearing out components far ahead of schedule. An undersized unit runs constantly trying to keep up with Texas summer heat and never quite gets there, driving up energy bills and shortening its own lifespan. Expedition HVAC performs a Manual J load calculation on every installation, taking into account your home's square footage, insulation levels, ceiling height, window placement, and sun exposure to determine the correct system size — not just "the same size as what was there before."

On efficiency, Texas regulations require a minimum of 15 SEER2 for new installations — but for DFW homeowners who run their systems heavily from May through September, we generally recommend 17–20 SEER2. The energy savings over a cooling season often justify the modest upfront cost difference, and higher-efficiency systems typically run quieter and manage humidity better. For equipment, Expedition HVAC installs Carrier, Trane, and Amana systems — three brands with strong track records in hot, humid climates like North Texas. Each offers a range of efficiency tiers, and we'll match the right brand and model to your home's needs and budget rather than defaulting to whatever's easiest to install.
