Austin HVAC Repair, Installation & Maintenance
For Austin residents, Lewisville HVAC is the way around every bad HVAC experience you've heard about: the no-show appointment windows, the mystery invoices, the replacement pitch for a system that needed a $40 part. We do it differently. A real person answers, a technician shows up on time, the diagnosis is explained clearly, and the price is agreed before any work begins. Repairs, installations, duct cleaning, and seasonal maintenance, all handled by experienced pros who know the area.

Complete Heating & Cooling Services for Austin Properties
We service every type of heating and cooling equipment you'll find in local homes and businesses, from central air conditioners and gas furnaces to heat pumps and ductless mini-splits. It makes no difference whether the building is a starter home, a townhome, or a storefront. Our technicians understand the local weather, the age and construction of local homes, and the code requirements that apply to new installations, and that knowledge shows up in the quality of every repair.
Most homeowners we work with need one of three things: a repair, a replacement, or a seasonal tune-up. Repairs are usually quick: a failed capacitor, a corroded flame sensor, a refrigerant leak, or a seized blower motor. Replacements get a proper load calculation, not a guess based on the old unit's tonnage, which keeps temperatures even and stops the new equipment from short-cycling its way to an early failure. Tune-ups cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, which does more than anything else to extend the life of your system.
Commercial work makes up a large share of our work too. We service rooftop units, split systems, and ventilation equipment for restaurants, shops, offices, and multi-unit properties, and we know that every hour of downtime costs the business. To keep disruptions short, we carry common parts on every truck, diagnose quickly, and plan larger jobs around your operating hours whenever possible.
Quick Heating and Cooling Help in Austin
Call us with a problem and a real person answers, not a phone tree. Most calls get scheduled the same day or the next, and urgent calls, a dead air conditioner during a heat wave or a furnace that goes out on a freezing night, jump to the top of the schedule. We keep the process simple so nobody is stuck waiting for a callback.
Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip whenever the system starts, iced-over evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have simply given up. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to complete most repairs in a single visit. Pricing is always upfront, so you know exactly what the work will cost before we begin.
Two situations call for a quick step from you before a technician arrives. The first is an iced-over air conditioner: turn the system off at the thermostat and set the fan to "on" so the moving air thaws the coil, because continuing to run it can overflow the drain pan and damage the compressor. The second is a furnace that short-cycles or produces a burning smell. Turn it off at the service switch and give us a call. That small step can prevent a far bigger repair.
Keeping Your Austin HVAC System Running Longer
A little routine care makes all the difference between a system that runs for years and one that quits in the middle of a heat wave. Our advice for homeowners is a short list: fresh filters every one to three months, two feet of clearance around the outdoor condenser, a spring rinse of the condenser coil, and a professional tune-up every spring and fall, so small issues get caught early.
Equipment age plays a big role. With regular service, central air typically lasts 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts showing warning signs, like higher energy bills, rooms that never reach the setpoint, or one repair after another, it's smart to start planning a replacement. A planned replacement costs less and is far less stressful than an emergency swap during the worst heat wave of the year.
Minor issues rarely stay small when they're ignored. Take a weak capacitor: swapping it out is a quick, affordable repair, but left alone for a season, it can take the compressor with it, and suddenly a minor fix becomes a full system replacement. That's why we ask homeowners to save our number in their phone and reach out at the first sign of trouble. Catching it early saves money and spares you a miserable night.
Typical Heating & Cooling Issues in Austin
HVAC systems in this area face a familiar set of problems. Long cooling seasons push compressors and capacitors to their limits, and humidity and airborne grit slowly foul outdoor condenser coils, cutting efficiency years before the equipment should show its age. Clogged filters quietly choke off airflow, freezing evaporator coils in summer and overheating furnace heat exchangers in winter, a slow kind of damage most homeowners never see coming.
Our technicians also run into the full range of component failures in local homes: weak capacitors that leave the condenser humming without starting, contactors with pitted points, cracked igniters and dirty flame sensors that lock furnaces out on cold mornings, slow refrigerant leaks that leave the house lukewarm by afternoon, and blower motors worn down by years of restricted airflow. The area's mix of older homes brings undersized returns, leaky duct runs, and rooms the original system was never designed to condition.
Every one of these problems is fixable, and most are much less expensive when caught early. If your system is doing anything unusual, strange noises, weak airflow, rooms that won't hold temperature, bills creeping upward, a quick diagnostic visit from our team catches the small problem before it becomes an expensive one.
