Precision Sizing for Peak Summer Demand. Lower Bills, Higher Comfort.
It’s a baseline requirement for a safe, habitable home. The Austin climate, famous for its relentless triple-digit “sweat-fests” and high humidity, demands more than just a quick fix; it requires precision and technical expertise.
At Service First HVAC & Electrical, we aren’t a faceless national chain. We are a local, veteran-owned AC company led by Rolando Tey, a Master Technician who has been performing HVAC installations since 1989. Rolando’s philosophy is the heartbeat of our company:
“There’s only one way to do it. It’s the right way. And if not, don’t do it at all.”
The most important day in the life of an air conditioner is the day it is installed. Even the most expensive, high-efficiency brand will fail prematurely if it is installed incorrectly. To ensure your home stays cool without wasting energy, our certified technicians consult with you, perform detailed Manual J load calculations, and ensure you have exactly what you need and nothing you don’t.
We don’t “guestimate” based on square footage. We determine the correct size based on your home’s insulation, orientation to the Texas sun, and total window area.
“Improper sizing can reduce efficiency by 30% and lead to short-cycling that kills the compressor”
Many homes have been remodeled, which often “robs Peter to pay Paul,” destroying the original airflow footprint. We identify leakage and sizing mismatches before the new is placed to ensure your repair isn’t pushing cooled air into an uninsulated attic.
Our master electricians won’t just swap the box. We handle the panel upgrades and new circuit installations required for high-efficiency air conditioning loads to ensure your whole-home ecosystem is safe.
Determining when to move on from your current setup is often a matter of safety and long-term value. Here are the signs that it’s time to stop patching up the old:
Most mechanical setups in Central Texas face extreme stress; if yours is over 10 to 12 years old, the internal components are likely reaching the end of their reliable lifespan.
If a single fix costs more than half the value of the entire setup, investing that money into a modern, high-efficiency setup is often the smarter financial move.
If you are calling for help multiple times a season, the compounding costs of small fixes will quickly outweigh the price of a more dependable new option.
Electrical faults or compromised internal parts can become hazards. Because we are led by a master electrician, we prioritize your home’s safety above all else.
Older systems work significantly harder to produce less cooling, leading to monthly costs that are far higher than a modern, correctly sized alternative.
We do the work right the first time to minimize disruption to your life. We won’t replace if a repair will do. We care about people and doing the right thing for our neighbors. Our replacement process is highly coordinated, often involving site assessment, permit procurement, and the removal of the old on a single day.
Our local team of certified technicians offers decades of combined experience and service. We believe that master-level expertise is the only way to ensure home comfort for everyone.
We ensure the capacity, indoor coil, and blower motor are optimized for maximum longevity.
We prefer using OEM parts specifically made for your brand rather than universal motors that force you to pay for features you don’t need.
We provide clear, upfront pricing so you know exactly what to expect throughout the AC replacement service. Everything you need, nothing you don’t.
Our commitment to you doesn’t end when the last screw is tightened. Because we believe in the “Right Way” of doing things, we provide a level of post-job support that most big-box chains simply won’t offer.
We believe honest air conditioning service should be accessible to every family.
We provide high-performance cooling solutions designed to endure the relentless Central Texas sun. With lead technician and owner Rolando serving the greater Austin community for decades, Rolando and the team bring the “Right Way” philosophy to every project, ensuring Austin’s historic Tarrytown estates and the newest builds in Cedar Park receive the same master-level precision. Our owner, an Austinite of 26 years, oversees our local operations to guarantee that every setup we install is battle-tested for the unique demands of our neighborhoods.

Precision Sizing
Every job begins with a detailed load calculation to ensure everything is perfectly matched to your home’s footprint and sun exposure.
Generally, if your HVAC is over 10–12 years old and the repair cost exceeds 50% of the unit’s value, replacement is smarter. However, we provide professional second opinions. Rolando won’t push a replacement if a “Right Way” repair can reliably restore your comfort.
This is usually an airflow footprint issue caused by remodeling or additions that “rob Peter to pay Paul.” Our technicians perform deep inspections to see if your ductwork needs rebalancing or if your unit is simply undersized for your home’s current footprint.
Consistent, professional maintenance is the secret to a 20-year system. Think of it like an oil change for your car—it prevents $1,500 compressor failures down the road. Our plans include pre-summer tune-ups addressing refrigerant levels, electrical connections, and coil cleanliness.
Be careful. We often see electrical faults caused by other contractors—like a sheetrocker accidentally driving a screw through a wire. Because we are led by a dual licensed master electrician and HVAC tech, we ensure your panel and wiring can safely handle the high-draw demands of your HVAC.
Many companies just blow out the line with air, but that doesn’t remove the “slime” or biological growth inside the pipe. The “Right Way” involves flushing the line thoroughly and treating it to prevent future clogs. We also ensure your float switches are wired correctly so that if a clog does happen, everything shuts down before water ruins your ceiling.
Universal parts are designed to work on many different machines, but they often require some less than standard rigging to fit where they need to fit. They may draw more power or fail sooner. OEM (Original Equipment Manufacturer) parts are built specifically for your unit, ensuring the exact performance and efficiency the manufacturer intended.
We highly recommend smart thermostats because they allow for precise calibration and remote monitoring, but we help you choose the one that fits your lifestyle. Proper calibration during installation is key—if a thermostat isn’t set correctly, it can cause the system to cycle too frequently, wearing out the components.
Our team arrives on time and works to minimize disruption. Because we handle the electrical and HVAC work simultaneously, you don’t have to wait for separate contractors to coordinate. We remove the old, install the new, and perform a rigorous commissioning process to verify everything is running perfectly before we leave.
