When You Need AC Installation

Replacement isn’t always obvious. Sometimes the unit still runs, but it’s costing you more than a new system would. Here’s when San Antonio homeowners call us for an AC Replacement or full install:

• Your system is 12 to 15 years old. Most AC units in San Antonio wear out faster than the national average because our cooling season runs from March through October. A 14-year-old unit has already given you its best years.
• Repair bills are stacking up. If you’ve spent $800 or more on repairs in the past two seasons, you’re funding a dying system. In neighborhoods like Alamo Heights and Stone Oak, we see this constantly, and the math rarely favors another patch job.
• Your energy bills keep climbing. A degrading compressor or leaking coil forces the system to run longer to hit the same temperature. That shows up on your CPS Energy bill month after month.
• The system uses R-22 refrigerant. R-22 was phased out years ago, and the remaining supply is expensive. If your unit needs a refrigerant recharge with R-22, you could be looking at $200 to $400 just for the coolant, and that’s before labor. Replacement starts making real sense.
• Uneven cooling between rooms. If your upstairs bedroom in Helotes is 10 degrees warmer than the living room, your system is struggling against aging ductwork or an undersized unit.
• Humidity problems indoors. San Antonio’s humidity is brutal from May through September. An older system that can’t pull moisture from the air leaves your house feeling sticky even when the temperature reads low.

If any of these sound familiar, home comfort for the next decade starts with a free assessment. We’ll tell you straight whether repair still makes sense or whether replacement is the better money move.

Our AC Installation Process

Here’s exactly how a full install works with Halden Heating and Air San Antonio. No surprises, no vague steps, no waiting around wondering what’s happening.

1. Free in-home assessment and load calculation. We measure your home’s square footage, window orientation, insulation levels, and existing ductwork. This Manual J load calculation determines the exact system size you need, not a guess based on what the old unit was.
2. Written quote with equipment options. You get a line-item price covering the unit, labor, any ductwork modifications, and disposal of the old system. We explain the difference between efficiency tiers in plain English, so you’re choosing based on real numbers, not marketing terms.
3. Schedule with a live arrival window. You pick the day, and we send a background-checked, uniformed technician with a live arrival time you can track from your phone. No four-hour window, no sitting around.
4. Full system installation. We remove the old equipment, install the new condenser and air handler, connect refrigerant lines, and test everything. Most residential installs take one full day from arrival to final walkthrough.
5. System startup and performance verification. We measure refrigerant pressures, check airflow at every vent, and confirm the thermostat is communicating correctly with the new system.
6. Final walkthrough and written guarantee. Before we leave, you’ll see the system running, we’ll walk you through the new thermostat, and you’ll have our 365-Day Done Right Promise in writing, covering the full year of accountability on the completed job.

AC Installation Pricing in San Antonio

You should know what a new system costs before you start calling around. Here are honest ranges for the San Antonio market based on what we install regularly across Bexar County:

System Type	Typical Installed Cost in San Antonio
Basic 14 SEER2 single-stage system (2-3 ton)	$6,500 – $8,500
Mid-range 16 SEER2 single-stage system (3-4 ton)	$8,500 – $11,000
High-efficiency 18-20 SEER2 two-stage system (3-5 ton)	$11,000 – $14,000
Variable-speed inverter system with full communicating thermostat	$13,000 – $18,000+

What moves the number? Three things: the size of your home, the efficiency tier you choose, and whether your existing ductwork needs work. A 1,400-square-foot home in Jefferson needs a smaller system than a 3,200-square-foot two-story in Dominion. Ductwork modifications add $1,500 to $4,000 depending on how much of the existing layout we’re reworking.

We install systems from Rheem, York, and Daikin, among others. Each brand has different price points, and we’ll walk you through what actually matters for a San Antonio climate: high SEER2 ratings for our long cooling season, and strong humidity control for our Gulf Coast summers.

The quote you get is the price you pay. Not a penny more. We put it in writing before any work begins, and that’s the Halden standard. Call (903) 623-6784 for your free estimate.

Benefits of Replacing Your AC

A new system isn’t just about cold air. Here’s what changes when you replace an aging unit in San Antonio:

• Lower monthly energy bills. A 16 SEER2 system uses roughly 30% less electricity than a 10 SEER unit from 15 years ago. With San Antonio’s seven-month cooling season, that adds up fast.
• Better humidity control. Newer systems run longer at lower speeds, which pulls more moisture from the air. You’ll feel comfortable at 76 degrees instead of needing to drop the thermostat to 72.
• Quieter operation. Modern condenser units run at 55 to 65 decibels. Older units often run at 75-plus. That’s the difference between a conversation on the patio and having to raise your voice.
• A written guarantee. Every Halden install includes our 365-Day Done Right Promise. If anything’s not right within that year, we come back and make it right without a fight.
• No more R-22 costs. New systems use R-410A or A2L refrigerants, which are more affordable and not being phased out. You’ll never pay $200-plus for obsolete coolant again.

FAQs – AC Installation

How much does AC installation cost in San Antonio?

AC installation in San Antonio typically costs between $6,500 and $14,000 for a complete system, with most mid-range installs landing around $9,000 to $11,000 for a 3-ton unit. Your exact price depends on home size, efficiency tier, and ductwork condition. Call (903) 623-6784 for a free written estimate.

How long does AC installation take?

Most residential AC installations take one full day, roughly 6 to 10 hours from arrival to final walkthrough. Larger jobs involving significant ductwork replacement can stretch to two days, and we’ll tell you upfront if yours falls into that category.

Is it better to repair or replace my AC in San Antonio?

If your system is over 12 years old and the repair costs more than $1,500, replacement is usually the smarter financial move. A good rule of thumb: multiply the repair cost by the age of the unit in years. If that number exceeds $5,000, put the money toward a new system instead.
