Complete Comfort Care in San Antonio

Comfort in San Antonio shouldn't depend on the season. Conroe HVAC keeps local homes and businesses at the right temperature year-round with fast, professional heating and cooling service, from quick furnace repairs to properly sized new systems. Our technicians know the housing stock here, which means we've seen how these systems fail locally and we arrive prepared, with capacitors, contactors, igniters, and motors already on the truck. Call (936) 209-8779 and we'll get the fix started.

Complete Heating & Cooling Services for San Antonio Properties

Whether you own a single-family home, a small apartment building, or a commercial space in town, we have the expertise and equipment to handle the full range of heating and cooling work. Our technicians have spent years working on central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits across the region, and we understand the climate patterns, housing stock, and local code requirements that shape how systems perform here.

Most homeowners we work with need one of three things: a repair, a replacement, or regular maintenance. Repairs tend to be quick: a failed capacitor, a corroded flame sensor, a slow refrigerant leak, or a worn-out 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 equipment life.

Commercial service is a big part of what we do as well. We service rooftop units, split systems, and ventilation equipment for restaurant kitchens, retail stores, offices, and multi-unit properties, and we know that every hour of downtime hurts 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

Call us about a problem and a real person picks up, not a recording. The majority of service requests get scheduled within a day, and true emergencies, a dead air conditioner during a heat wave or a furnace that fails on a freezing night, jump to the top of the schedule. Scheduling stays flexible so nobody is left waiting for a callback.

The emergency calls we run tend to follow a pattern. On the cooling side, it's warm air from the vents, an outdoor unit that hums without starting, or an evaporator coil iced over. On the heating side, it's a furnace that lights and then shuts down. And any time of year, it's breakers that trip every cycle, clogged condensate drains overflowing into the furnace cabinet, and thermostats that stop responding. Since our trucks carry capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, the majority of these calls get fixed on the first trip, at a price you approve before we start.

If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and strain the compressor. If a furnace is short-cycling or you smell something burning, turn it off at the service switch and call (936) 209-8779. A few minutes of caution can head off a much larger repair.

Keeping Your San Antonio HVAC System Running Longer

Most mid-season breakdowns start with maintenance that never happened, and the habits that prevent them are simple. Swap your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and hose off the condenser coil once a year in spring. Then book a professional tune-up twice a year, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

The age of your equipment matters just as much. 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 showing warning signs, like rising energy bills, rooms that never reach the setpoint, or repeat service calls, it's time to plan a replacement. A planned replacement is cheaper and is far less stressful than an emergency swap during the first heat wave of summer.

The earlier you report a comfort problem, the cheaper it usually is. A capacitor that's starting to fail costs little to replace, yet that same capacitor, neglected for a season, can take out the compressor and turn a simple fix into a full system replacement. Save our number on your phone now so help is one call away the moment something seems off in your home. A quick call saves time, money, and miserable nights.

Typical Heating & Cooling Issues in San Antonio

Most local HVAC failures announce themselves before they happen. A breaker that trips every few days, a condenser that hums louder each month, rooms drifting further from the thermostat setting, a musty smell at startup. Those are early signs of failing capacitors, refrigerant leaks, dirty coils, and duct problems, and caught early they're an affordable repair. Left alone, they take out compressors and heat exchangers, the two most expensive parts in the system. We diagnose the cause, not just the symptom, so small problems stay small.

Why San Antonio Homeowners Trust Us

What homeowners here get with Conroe HVAC comes down to a few things: fast scheduling, honest diagnosis, and workmanship that holds up. We answer quickly, arrive prepared, and fix causes rather than symptoms, checking the airflow, charge, and electrical conditions that killed the failed part in the first place. The price is set before work starts, and it stays put. Whether it's a midnight furnace failure or a planned system upgrade, the job is done right on the first visit.

Your HVAC Questions Answered

All major brands, including Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can source brand-specific components quickly when a repair requires them.
Both. Most calls start as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from all the major manufacturers. When a system can't be saved, we take care of the full replacement, from sizing the new equipment and hauling off the old unit to installation and testing in every mode. Whichever way it goes, you'll see a written quote for each option before you decide.
Absolutely. Mini-splits are ideal 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 take care of the line set, condensate drainage, and electrical connections correctly. If central equipment is the better fit, we'll tell you that too.
It depends on the job. Most repairs come in between $150 and $650, depending on the part that failed and the type of system. A complete system replacement typically costs about $5,000 to $12,000 installed, with size and efficiency making the difference. Before we begin, we provide a written quote based on the diagnostic, and that number doesn't change.
Check the thermostat mode and batteries, the air filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has built up on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (936) 209-8779. We'll get a technician headed your way right away.
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 window when you call (936) 209-8779. Once our technician arrives, capacitors, contactors, igniters, and motors are already on board, so the majority of problems get fixed during that first visit.
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 peak of summer, and lower energy bills often cover the cost of the visit.
It depends on two things: the system's age and what actually broke. A system under about 10 years old is almost always worth repairing. Beyond about 15 years, or if the compressor or heat exchanger goes, a new system is usually the better use of your money, especially once you factor in the efficiency improvements of modern equipment. Our technicians lay out both numbers side by side and leave the decision to you.
