AC Installation & Replacement in Mission, TX and the Rio Grande Valley
Next-Day AC Installs Often Available
AC installation & replacement is a bigger call than a repair, and nobody should have to make it on a 100-degree afternoon with the house sitting at 88. Frontier Cooling & Heating has been putting new systems into Valley homes since 2006, working out of our office on Griffin Parkway in Mission.
We're family-owned and Latino-owned, licensed and insured, and we have earned the Carrier President's Award five years running. Mr. Joe Villegas built this company on one rule that still holds: treat every customer like family, because this is our community too.

What AC Installation & Replacement Includes
A new system is more than a box on a pad. A proper AC replacement covers the outdoor condenser, the indoor evaporator coil and air handler or furnace, the refrigerant line set, the thermostat, and the drain. Swap only the outside half and you can end up with mismatched equipment that never reaches its rated efficiency.
It starts with an onsite evaluation. We look at the size of the house, the attic, the ductwork, and the electrical service, then recommend equipment that fits. That usually means central air installation, sometimes a package unit where everything sits in one cabinet outside, and sometimes replacing the whole system when the heating side is worn out too.

Signs Your AC Is Ready for Replacement
Nobody wants to shop for a new AC unit. But a few signs say the money is better spent on AC installation & replacement than on another service call.
The system is 12 to 15 years old or more. Repairs come every summer. The power bill keeps climbing while your habits stay the same. Some rooms never cool down. Or the unit runs on an older refrigerant that keeps getting harder and pricier to find.
The best time to plan an air conditioner installation is March or April, after the winter Texans head north and before the first week over 100. Waiting for a July breakdown means making a big decision in a hurry.


AC Replacement After a Major Part Fails
Sometimes the decision gets made for you. A compressor dies. An evaporator coil leaks for the third time. The outdoor coil is corroded through.
When the rest of the system is young, one part can make sense: a condenser replacement or an evaporator coil replacement keeps a newer system running for years. When the system is older, a new compressor in a 14-year-old unit is usually money you will not get back, and AC unit replacement wins the math.
If repair is the better move, we will say so and point you to our AC repair service instead. Our job is to give you honest numbers both ways.
Central AC and Split System Installs
Most Valley homes run a split system: a condenser outside and an air handler or furnace in the attic or a closet.
Central AC installation replaces both halves together, so they are matched and rated as a set.
Package Unit Installation
Some homes, including many older houses and manufactured homes, keep everything in one cabinet outside.
Package unit installation keeps that layout, with the new unit set level and tied into the existing ducts.
High-SEER2 Efficiency Upgrades
Our cooling season runs most of the year, which is exactly where high-efficiency (high-SEER2) AC upgrades pay off.
We show you the equipment options side by side so you can weigh the price against the monthly savings.
Full HVAC System Replacement
When the AC and the heating side are both near the end, a full HVAC system replacement handles everything in one job.
Rooms with no ductwork are often a better fit for ductless mini-split installation, and some homes do better on a heat pump.
How Frontier Installs a New AC System Right
A new system only performs as well as it is installed. These are the parts of the job we never rush.
Equipment Sized to Your Home
Bigger is not better. An oversized unit cools fast, shuts off, and leaves the house clammy, and you feel that in Valley humidity. We size the system to the house, its insulation, its windows, and its ductwork.
A Clean Vacuum and a Correct Charge
We pull a deep vacuum on the line set before releasing refrigerant, then check the charge with the system running. Skipping that step is where a lot of new systems start failing early.
Ductwork Checked Before It Is Reused
A new unit on leaky ducts wastes part of what you paid for. If the ducts are damaged or undersized, we will show you, and our air duct replacement crew can fix them during the same project.
Backed by a 100% Money-Back Guarantee
Every system installation is covered by our 100% money-back guarantee. We would not offer it if we were not confident in the work.


What Installation Day Looks Like With Frontier
An Onsite Evaluation and Clear Options
We start at the house, not on the phone. After the evaluation you get equipment options and pricing before anything is ordered.
Next-Day Installation in Many Cases
In many cases we can install the next day, sometimes sooner, depending on equipment availability and permitting. We confirm the timeline once the evaluation is done.
Startup, Testing and a Walkthrough
Once everything is in, we start the system, test it, and walk you through the controls. If you want an upgrade, we can add a smart thermostat while we are there.
Care Plans That Protect a New System
A new system still needs yearly care. Our Cowboy Kool Club membership covers routine tune-ups and priority scheduling.
New AC Unit Cost and Financing Options
Central AC installation cost depends on the size of the house, the efficiency of the equipment, the ductwork, and what the install requires, so we do not quote exact prices sight-unseen. We can give you a rough range over the phone, then exact pricing after the onsite visit.
Financing is available on HVAC replacement and new system installs, subject to approval. See our financing options, and check our current installation specials before you buy.

AC Installation & Replacement FAQs
Should I repair or replace my air conditioner?
It depends on the age of the system, the part that failed, and what the repair costs next to a new system. We lay out both options with prices so you can decide.
How much does AC installation & replacement cost in Mission?
Exact pricing needs an onsite visit, since the house, the ductwork, and the equipment you choose all change the number. We give a rough range over the phone and firm options with pricing before any work starts.
What should I do before installation day?
Make sure we can reach the thermostat, the indoor unit in the closet, attic, or garage, and the outdoor unit. Clear a path to each one and put pets up for the day.
Do you install mini-splits and heat pumps too?
Yes. We handle mini split installation for rooms without ductwork, ductless AC installation for additions and garages, and heat pump installation for homes that want heating and cooling from one system.
Is financing available for a new AC in the Rio Grande Valley?
Yes. Financing is available for system replacements and certain larger repairs, subject to approval. We also accept card, cash, Apple Pay, and other standard payment methods.
