AC Replacement in Austin, TX
Expert Installation from Air Runs Services
We make replacing your AC transparent, straightforward, and easy to understand.
Why Buying an AC Is Different Than Buying Other Appliances
Most people assume buying a new AC is like buying a new refrigerator: you pick a size, plug it in, and it works. But an air conditioner relies heavily on how your specific home is built.
Traditional HVAC companies often guess what size system you need based purely on square footage. The problem? Two homes with the exact same square footage can hold heat completely differently depending on their windows, shade, insulation, and attic ductwork.
If a company installs a unit that is too big, it turns on full blast, cools the air too quickly, and shuts off before it can remove humidity — leaving your home feeling cold and damp. If it’s too small, it will run constantly and struggle to keep up.
Our leadership combines deep technical expertise with whole-home knowledge. Air Runs co-founder Aaron DeKing brings more than 30 years of hands-on HVAC experience, while Doug Warriner and Phil Perry add over two decades of custom homebuilding expertise. Because of this combined background, we look at your entire house — not just the metal box outside — to ensure your new system is sized perfectly for your home’s actual needs. Learn more about our background and leadership on our About Air Runs Services page.
The Air Runs Zero-Commission Guarantee
In the HVAC industry, many technicians earn commission on what they sell. That means the person inspecting your broken AC might get a direct cash bonus if they convince you to buy a brand-new $15,000 system.
We do things differently. Air Runs technicians earn an hourly rate with zero commission. Their job is simply to give you clear, accurate advice.
If your current unit can be fixed safely and affordably, we will tell you. If replacing it makes better financial sense, we will give you clear, easy-to-understand options with zero high-pressure sales pitches. We even offer free second opinions if another company gave you a replacement quote and you want to double-check their recommendations.
Our Straightforward 4-Step AC Replacement Process
We take the confusion out of getting a new AC by walking you through four clear steps.
Step One: Tailor-Fitting Your System
When dirt accumulates on your coils or filters clog, your system draws more power to move air. Professional tuning restores original operating efficiency, keeping your money where it belongs—in your bank account.Instead of guessing, we measure your home’s actual heat load using official ACCA Residential Load Calculation Standards. We check your insulation, window directions, and ductwork to find and fix any hidden hot spots before we install anything.
Step Two: Clear Options and Upfront Pricing
We present clear, customized choices designed around your budget and comfort goals. We lay out standard upgrades alongside ultra-efficient models, highlighting expected energy savings and any local Austin energy rebates you can claim.
Step Three: Professional Installation by Local Experts
Our installation teams treat your house like a custom-built home. We seal air leaks, level outdoor equipment, and tune the system for maximum airflow. Because our team handles HVAC, electrical, and plumbing work, any necessary electrical upgrades are done in-house without the hassle of hiring outside contractors.

Modern “Cruise Control” Cooling: Mitsubishi Electric Diamond Contractor
As a certified Mitsubishi Electric Diamond Contractor, we offer modern, ultra-quiet heat pump systems that act like cruise control for your home’s temperature.
Older AC systems operate like a basic light switch — they run at 100% full blast or turn completely off. Modern variable-speed systems adjust gently in real time. They run quietly in the background at lower speeds, keeping your temperature steady and removing humidity while using far less electricity.
Our Diamond Contractor certification means our team has undergone specialized factory training, allowing us to offer extended warranty protection that standard installers cannot match.

Frequently Asked Questions About Austin AC Replacement
How do I know if I should repair or replace my AC unit?
If your air conditioner is over 10 to 12 years old, requires frequent repairs, uses obsolete R-22 refrigerant, or causes your summer electric bills to spike, replacement is usually the smarter long-term investment. A good general rule is the “Rule of 5,000”: multiply the age of your system by the estimated repair cost. If the total exceeds $5,000, replacement makes more financial sense. At Air Runs Services, our zero-commission technicians provide honest diagnostics and free second opinions so you can make the right decision without sales pressure.
How do you determine what size AC replacement my Austin home needs?
We never guess system sizing based on square footage alone. Air Runs Services performs detailed home heat-load calculations that account for your home’s specific orientation, window placement, insulation quality, ductwork condition, and ceiling height. Sizing your system accurately prevents short-cycling, balances humidity levels, and eliminates stubborn hot spots.
How much can I save on electric bills with a new high-efficiency AC?
Upgrading from an older 10 to 12 SEER system to a modern 16+ SEER or variable-speed heat pump can reduce your cooling energy consumption by 20% to 40%. Variable-speed inverter systems adjust their output in real time to run quietly at lower speeds, maintaining steady indoor temperatures while using significantly less power than older on/off units.
How long does an AC replacement take?
A standard residential AC replacement is typically completed in a single day, usually taking between 4 to 8 hours. If your project involves custom duct modification, new electrical panel work, or multi-zone ductless installations, our team will provide a clear project timeline before work begins.
What warranties come with a new AC installation from Air Runs Services?
Every new system we install includes up to 10 years of manufacturer parts warranty coverage paired with 2 years of extended labor coverage from our team. As a certified Mitsubishi Electric Diamond Contractor, we can also offer extended manufacturer protection on select high-efficiency systems.
