Fort Worth HVAC Repair, Installation & Maintenance

Fort Worth homeowners don't call an HVAC company on a good day. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays ice cold no matter what the thermostat says. San Marcos HVAC built its local reputation on those calls: picking up the phone, arriving with stocked trucks, and fixing the actual fault instead of selling a new system. From quick capacitor swaps to full heat pump installations, our technicians handle every job with straight answers and honest numbers, and we treat your home like it belongs to a neighbor, because around here, it does.

Full-Service HVAC Care for Fort Worth Homes and Businesses

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 doesn't matter whether the building is a single-family house, a condo, or a busy office. Our technicians know the local climate, the age and construction of local homes, and the code requirements inspectors enforce, which pays off in the quality of every repair.

A typical week for our residential technicians includes capacitor and contactor replacements, flame sensor cleanings, refrigerant leak searches, blower motor swaps, and at least one full system replacement or ductless install. When we do replace equipment, we size it with a room-by-room load calculation rather than matching the old unit. Right-sized equipment holds even temperatures, keeps utility bills reasonable, and steers clear of the short-cycling that wears out compressors early. Beyond repairs and replacements, we recommend seasonal tune-ups that clean coils, confirm the refrigerant charge, test safety controls, and measure static pressure, the most effective thing you can do for a longer-lasting system.

Commercial service is a big part of what we do as well. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurants, shops, offices, and multi-unit buildings, and we know that a day without cooling hurts your bottom line. To keep disruptions short, we keep common commercial parts stocked, diagnose quickly, and schedule repairs around your operating hours whenever possible.

When Your System Fails in Fort Worth

Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll reach a real person who will get a technician headed to your property quickly. Arrival in the area is usually 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.

The emergency calls we answer tend to follow a pattern. On the cooling side, it's an AC blowing warm air, an outdoor unit that hums without starting, or an evaporator coil frozen solid. On the heating side, it's a furnace that lights and then shuts down. And any time of year, it's breakers that trip whenever the system starts, plugged condensate drains overflowing into the furnace cabinet, and thermostats that have quit. Since our trucks carry capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, most of these get fixed in one visit, with the price agreed before any work begins.

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, shut it down at the switch and call (737) 344-9567. A few minutes of caution can head off a much larger repair.

Keeping Your Fort Worth HVAC System Running Longer

The best way to avoid a mid-season breakdown is simple maintenance. We recommend that homeowners replace filters every one to three months, keep shrubs and grass trimmed two feet back from the outdoor condenser, rinse the condenser coil each spring, and have a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still cheap.

How old is your system? Its age tells you a lot. With regular service, most air conditioners reach 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is past that point and is also showing rising bills, rooms that never quite reach temperature, or repeated repairs, it's usually due for a planned replacement, which is almost always cheaper and less stressful than a rushed emergency install in peak season.

If comfort problems do show up, acting quickly keeps them small. A weak capacitor is a quick fix. The same capacitor left alone for a season can take the compressor with it and turn a minor repair into a full system replacement. It's smart to keep our number saved on your phone so you can reach us at the first sign of trouble. Early intervention saves time, money, and sleepless nights.

Common HVAC Problems in Fort Worth

The service calls we run around here follow familiar patterns. In summer it's warm air from the vents, weak capacitors that finally quit on the first hot week, and condensate drains backing up into the furnace cabinet. 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 (737) 344-9567 before the season turns it into an emergency.

Your HVAC Questions Answered

We work on nearly every brand installed in local homes, from Carrier, Trane, and Lennox to Rheem, Goodman, and York, along with ductless systems from Mitsubishi, Fujitsu, and LG. Universal parts on the truck cover most units, and if a job needs a factory part, we can source it quickly.
First, rule out the easy stuff. Make sure the thermostat is in cooling mode and the batteries aren't dead, swap the filter if it's dirty, and check the breakers for the indoor and outdoor units. Ice on the copper lines or an outdoor unit that hums but never starts means it's time to shut the system off, because running it can damage the compressor. Call us at (737) 344-9567 and we'll get someone moving your way without delay.
It depends on two things: the system's age and which part failed. Equipment younger than about 10 years is usually worth repairing. Once it's past 15 years, or if the compressor or heat exchanger is the part that failed, replacement usually makes more financial sense, especially once you factor in the efficiency gains of new equipment. Our technicians lay out both numbers honestly and let you choose.
Most calls are scheduled the same day, and a home with no heat or no cooling moves to the top of our list. When you call at (737) 344-9567, we'll give you a realistic arrival window, and because the technician arrives with capacitors, contactors, igniters, and motors already on board, the job usually wraps up in one trip.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit covers cooling: coil cleaning, a refrigerant charge check, capacitor testing, and airflow readings. The fall visit covers heating: burner cleaning, a combustion check, and safety control testing. Staying on that schedule adds years to your equipment, heads off breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in energy savings.
Yes, and they're often the best answer for additions, garages, sunrooms, and older homes that were never ducted. Every zone is sized to the actual load of its room. We map out where the indoor and outdoor units go and install the line set, condensate drain, and electrical work with care. And we'll be upfront if central equipment makes more sense for your home.
It depends on what's wrong. Most repairs come in between $150 and $650, depending on the part that failed and the type of system. A complete system replacement generally runs around $5,000 to $12,000 installed, with size and efficiency making the difference. Before we begin, you'll get a written quote based on the diagnostic, and that price holds.
Yes. We repair every major brand of air conditioners, furnaces, heat pumps, and ductless mini-splits. When a system is beyond saving, we handle the complete replacement: hauling away the old equipment, installing a properly sized new system, and testing it in every mode. You get a clear quote for each option before you decide.
