AC Installation in Houston, TX

AC Installation in Houston, TX

New AC installation in Houston runs roughly $3,750 to $9,800 for a complete system swap, with higher-end high-efficiency units and larger homes landing between $9,800 and $14,500. That range covers the condenser outside, the evaporator coil and air handler inside, the thermostat, new refrigerant linesets, and full-day labor from a two-person crew. Marco Benitez and the installation teams at Dalton Heating & Air Houston put the exact number in writing before any equipment is ordered or any work starts through our AC repair installation services.

If you’re weighing a repair versus a replacement, start with our AC Repair & Installation page for the full picture. This page is specifically about what happens when the old system is done and you’re putting in a new one.

Houston summers don’t negotiate. June through September, daytime highs sit above 92°F and evening lows rarely drop below 78°F, which means your AC compressor runs six to nine hours a day during peak season. A system installed wrong or sized on guesswork runs harder, breaks earlier, and costs more to operate every month. We replace systems in Katy, Cypress, Sugar Land, Pearland, The Woodlands, Kingwood, and everywhere inside Beltway 8 with AC Repair & Installation Near Me in Houston, TX.

When You Need AC Installation

Most Houston homeowners don’t plan for an AC Replacement; they’re told about it on the worst day of the year. These are the situations we see most often, and they’re all reasons to start planning a new installation rather than paying for another patch job.

• The system is over 15 years old. The average AC lifespan in the Houston area is 12 to 15 years because of how many hours the system runs each summer. Past that age, major components fail more often and efficiency falls off.
• The compressor failed and the unit is out of warranty. Replacing a compressor on a 12-year-old unit often costs $2,100 to $3,400, which puts you more than halfway to a full new system with a new warranty.
• You’re using R-22 refrigerant. Residential R-22 (what the trade calls the old Freon) was phased out of production in 2020. What’s left on the market is reclaimed and priced accordingly. A recharge on an R-22 system runs $150 to $300 per pound, and a system that takes 6 to 8 pounds gets expensive fast.
• Energy bills have climbed year over year. A 14-year-old SEER 12 system can use 38% more electricity than a modern SEER 16 or higher unit, and Houston’s electric rates make that a real monthly cost.
• Humidity stays high even when the house is cool. When a system can’t pull moisture out properly, most Houston homeowners notice mold-like smells, sticky-feeling rooms, and condensation on windows. An aging system with degraded evaporator coil performance is usually the cause.
• We’ve repaired the same problem twice in two seasons. Outside of capacitors and contactors (small jobs under $90), repeated failures are a pattern, not bad luck. At some point the math favors installing a new unit.

Our AC Installation Process

Every Dalton installation follows the same sequence. It’s written into The Garrison Code, which every Garrison Partners location operates under: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year.

Step 1: Free Load Calculation

Before any proposal, a Dalton technician measures your home’s conditioned square footage, window area, insulation level, and ceiling heights. Then we run a Manual J load calculation. This tells us exactly how many BTUs your house actually needs. Skip this step and the next install is a guess. We don’t guess on a $6,000 job.

Step 2: Written Quote, Zero Pressure

Based on the load calculation, we present a written quote with equipment options: good (base efficiency, lower upfront cost), better (mid-tier efficiency, best overall value), and best (highest efficiency, maximum monthly savings). You pick the tier. The price on the paper is the price you pay. No add-ons at the door.

Step 3: Equipment Order and Permit

For homes inside Houston city limits, a new AC installation requires a mechanical permit from the City of Houston Code Enforcement Office. Outside city limits in Harris County or Fort Bend County, requirements vary. We pull the correct permit for your property. Your quote includes the permit fee, which typically runs $80 to $250 depending on jurisdiction.

Step 4: Installation Day

Two technicians arrive in a marked Dalton van, in uniform, with background-checked credentials verified before dispatch. They lay down drop cloths and boot covers, disconnect and remove the old equipment, and set the new condenser on a new or existing pad. The full replacement takes one day in a standard home. Two-story homes or complex ductwork may take into a second day.

Step 5: System Startup and Verification

After the new unit is charged, we run a full startup sequence: check refrigerant pressures against the manufacturer’s spec, measure temperature differential across the coil, verify airflow at each supply register, and test the thermostat wiring. You get a written summary of those numbers before we leave.

Step 6: Your 365-Day Done Right Promise

Every Dalton installation includes a written 365-Day Done Right Promise. If anything about the installation does not hold up during that year, we return at no charge. Not a 30-day window, not a 90-day window. A full year.

AC Installation Pricing in Houston

Here’s the straightforward breakdown. These are real ranges for the Houston metro, based on what we install in Katy, Pearland, Cypress, and inside the Loop.

System Tier	Typical Efficiency (SEER2)	Price Range for a 2,000 sq ft Home
Base efficiency single-stage	14.3 to 15	$3,750 to $5,200
Mid-tier single or two-stage	15.2 to 17	$5,200 to $7,400
High efficiency two-stage or variable	17 to 20+	$7,400 to $12,500
Full high-efficiency system with ductwork modifications	16 to 19	$10,000 to $14,500

What moves the number: the size of your home (a 3,400 sq ft two-story in Sugar Land needs more tons than a 1,600 sq ft bungalow in the Heights), the efficiency tier you select, whether you need new ductwork or duct sealing, and whether the electrical panel needs a dedicated circuit upgrade (common in pre-1990 homes).

We install Carrier, Trane, Lennox, and Goodman equipment, and we service all nine major residential brands. Dalton technicians are factory-trained on these lines, which means we follow the manufacturer’s install manual to the letter. The trade will tell you that a correctly installed Goodman outlasts a sloppy Carrier install every time; installation quality is the whole game.

FAQs — AC Installation

How much does a new AC system cost in Houston?

A new central AC system in Houston typically costs $3,750 to $9,800, with higher-efficiency or larger-home installations running $9,800 to $14,500. The final number depends on home size, equipment tier, ductwork condition, and whether your electrical panel needs an upgrade. Call (903) 494-7686 and we’ll give you a free load calculation and a fixed written quote for your specific house.

How long does AC installation take?

A standard single-system replacement in a Houston home takes one day, roughly 6 to 9 hours from arrival to final system test. Two-story homes, complex duct runs, or installations requiring new electrical circuits can take into a second day. Your written quote will state exactly how long we expect the job to take.

Is it cheaper to repair or replace my AC in Houston?

If your system is under 10 years old and the repair is under $900, repair almost always makes sense. If the system is over 12 years old and the repair quote exceeds $2,000 (like a failed compressor), replacing the unit starts to pencil out, because a new system carries a new warranty and runs more efficiently in Houston’s heat. We’ll price both options for you in writing before you choose.

Can you install a new AC the same week I call?

We typically schedule installations within 3 to 7 days of your written quote, depending on equipment availability. During peak Houston summer demand, that window can stretch to 10 days for certain high-efficiency models. Same-week installation is often available for base and mid-tier systems. Call (903) 494-7686 to check current scheduling.

Do you pull permits for AC installation?

Yes, we pull mechanical permits for every installation where the local jurisdiction requires one. Inside Houston city limits, that’s the City of Houston Code Enforcement Office; in Harris County, Fort Bend County, Montgomery County, and Brazoria County, requirements differ, and we handle each accordingly. The permit fee is included in your written quote.

What does the 365-Day Done Right Promise cover?

The 365-Day Done Right Promise covers the installation workmanship for a full year from the day we finish. If anything about the installation does not hold up, we return and fix it at no charge. That promise is in writing, along with the written guarantee on every repair and the free return visit if any repair we perform fails within the guarantee period.

Why Houston Homeowners Call Dalton

Most HVAC companies in Houston make the same three promises: we show up on time, we charge a fair price, we stand behind our work. Dalton Heating & Air writes those promises down and signs them. The Garrison Standard, which every Garrison Partners location has operated under since 2003, means: the price you approve is the price you pay. The guarantee is on paper, not in a sales script. If the work fails inside the guarantee window, we come back for free.

Marco Benitez runs Dalton Heating & Air Houston with a simple rule: every job gets a written quote before any equipment is ordered, every technician arrives background-checked and in uniform, and every phone call is answered by a live person. That last part matters more than it sounds, because Houston AC failures don’t respect a 9-to-5, and neither do we. Call (903) 494-7686 at 2 a.m. and a person picks up.
