Trusted San Antonio HVAC Service

For San Antonio 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. From emergency repairs to planned upgrades, all handled by experienced pros who know the area.

Heating and Air Conditioning Service Across San Antonio

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 single-family house, a condo, or a busy office. Our techs know the local climate, the way homes here were built, and the code requirements that apply to new installations, which pays off in every diagnosis.

On the residential side, we take care of everything from quick fixes, like a failed capacitor, a burned contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, complete system replacements, and ductless additions. Every new system we install is sized with a proper load calculation rather than guesswork, so you get even temperatures and sensible utility bills instead of a unit that short-cycles itself to an early death. Our seasonal tune-ups clean coils, verify refrigerant charge, test safety controls, and check static pressure, the single best way to extend equipment life.

Commercial work is a big part of what we do too. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurants, retail stores, offices, and multi-unit buildings, and we know that every hour of downtime costs your bottom line. To keep disruptions short, we carry common parts on every truck, diagnose quickly, and schedule repairs around your operating hours whenever possible.

Fast HVAC Response in San Antonio

Heating and cooling failures rarely wait for a convenient day, which is why we offer prompt, flexible scheduling for most situations. When you call, you'll reach a real person who will get a technician dispatched to your door without delay. Arrival in the area is typically within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is exactly the kind of call we move to the front of the line.

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 common situations call for a quick step from you before a technician arrives. The first is an iced-over air conditioner: switch the system off at the thermostat and set the fan to "on" so the moving air thaws the coil, because running it frozen can overflow the drain pan and hurt the compressor. The second is a furnace that keeps cycling on and off or gives off a burning smell. Shut it down at the switch and give us a call. That small step can save you from a far bigger repair.

How San Antonio Homeowners Can Extend HVAC Life

A little routine care is the difference between a system that runs for years and one that breaks down 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 gentle rinse each spring for the condenser coil, and two professional tune-ups a year, so small issues get caught early.

Equipment age plays a big role. With regular service, a central air conditioner usually runs 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts acting up, like rising energy bills, rooms that won't reach the setpoint, or one repair after another, it's smart to start planning a replacement. Replacing on your own schedule is cheaper and causes far less stress than an emergency swap during the worst heat wave of summer.

Small problems don't stay minor for long. Take a weak capacitor: swapping it out is a short, affordable repair, but if it's ignored for a season, it can take the compressor with it, and just like that a minor fix becomes a full system replacement. That's why we encourage homeowners to save our number in their phone and call at the first sign of trouble. Catching it early saves time and money and spares you a miserable night.

Comfort Challenges San Antonio Homeowners Face

The service calls we run around here tend to follow the calendar. In summer it's air conditioners humming but not cooling, weak capacitors that finally quit on the first hot week, and iced-over evaporator coils. In winter it's furnaces that short-cycle, dirty flame sensors, and igniters that fail on the first cold night. Year-round we see clogged filters choking airflow, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. Every one of these starts small, and every one is cheaper to fix early. If your system is showing symptoms, call (469) 423-7641 before the season turns it into an emergency.

Why San Antonio Residents Choose Us

Choosing an HVAC company comes down to trust, and trust is earned on the job. Lewisville HVAC earns it by fixing what's fixable instead of replacing what isn't, by sizing replacements with real load calculations instead of guesswork, and by standing behind every repair long after the visit ends. We keep response times short throughout the area, and each visit wraps up with the system tested and your questions answered.

Common Heating & Cooling Questions

There isn't one magic number, but a few rules of thumb help. Most part failures on systems under about 10 years old are worth the repair. Past the 15-year mark, or after a failed compressor or cracked heat exchanger at any age, replacing the system usually comes out ahead, and newer equipment brings real efficiency gains. We'll give you both numbers honestly and let you decide, because we'd rather earn your trust than sell you a system early.
Yes, and for most homeowners it's the smartest money you can spend on a system. Each spring and fall, a technician cleans the coils and burners, checks the refrigerant charge and combustion, tests capacitors and safety controls, and measures airflow from supply to return. Catching a weak part during a tune-up is far cheaper than a breakdown in the middle of summer, and lower energy bills often cover the cost of the visit.
It depends on the job. Most repairs come in between $150 and $650, based on the part that failed and the type of system. A complete system replacement typically costs around $5,000 to $12,000 installed, depending on size and efficiency rating. Before any work starts, we provide a clear quote based on the diagnostic, and that number doesn't change.
Yes, we do both. We fix air conditioners, furnaces, heat pumps, and mini-splits regardless of brand. If replacement is the better call, we handle everything: removing the old unit, a properly sized new system, careful installation, and a full test of every mode. You get a clear quote for each option before you commit.
We service nearly every brand installed in local homes, including Carrier, Trane, Lennox, Rheem, Goodman, and York, along with ductless systems from Mitsubishi, Fujitsu, and LG. The universal parts on our trucks fit most units, and when a repair needs a brand-specific component, we can source it quickly.
Start with the simple checks: confirm the thermostat is set to cool and has fresh batteries, pull the filter and check for a clog, and look for a tripped breaker on both the indoor and outdoor units. If none of that helps and the outdoor unit hums but won't start, or you see ice on the copper lines, turn the system off before the compressor is damaged. Then call (469) 423-7641 and we'll send a technician to your home as fast as we can.
Yes. Mini-splits are a great fit for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the room it serves, place the indoor and outdoor units thoughtfully, and handle the line set, condensate drainage, and electrical connections correctly. If a ducted system is the better fit, we'll say so.
Usually the same day. Emergencies like a dead AC or a furnace that won't light take priority over scheduled tune-ups, and we'll give you an honest arrival time as soon as you call (469) 423-7641. Once our technician arrives, capacitors, contactors, igniters, and motors are already on the truck, so the majority of problems are fixed without a second trip.
