Heating and Air Conditioning Service Across San Antonio

Heating and cooling around here covers a lot of ground: aging furnaces on the older streets, high-efficiency heat pumps in recent construction, ductless mini-splits in additions and converted garages, and rooftop units on commercial buildings. Our team works on every one of those systems. Our technicians have years in the field, and we've learned how the weather here, the housing stock, and local code affect the way a system performs over time.

Most homeowners we meet need one of three things: a repair, a replacement, or regular maintenance. Repairs tend to be straightforward: a burned contactor, a dirty flame sensor, a refrigerant leak, or a seized blower motor. When we replace a system, it gets 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, and nothing does more to extend the life of your system.

Local businesses get the same attention. An overheated storefront or a freezing office drives customers and staff away, so our commercial technicians focus on fast diagnosis and keep high-failure parts on board for rooftop units, split systems, and ventilation equipment. Restaurants, retail shops, offices, and multi-unit buildings can count on us to work around their operating hours whenever possible.

When Your System Fails in San Antonio

Call us with a problem and a real person picks up, not a recording. Most calls are scheduled within a day, and true emergencies, an AC that quits in a heat wave or a furnace that fails on a bitter night, jump to the top of the schedule. Scheduling stays flexible so you're not 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 every time the system runs, 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 finish most repairs in a single visit. We provide upfront pricing every time, so you know exactly what the work will cost before we begin.

If your AC has iced over, the best 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 (469) 423-7181. A few minutes of caution can prevent a much larger repair.

Getting More Years From Your HVAC System in San Antonio

Most mid-season breakdowns trace back to maintenance that never happened, and the habits that prevent them are easy. Swap your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and rinse 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.

Age matters too. Most central air conditioners run 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15 with regular service. If your system is past that window and showing symptoms, such as rising energy bills, rooms that never feel comfortable, or repairs stacking up season after season, a planned replacement is nearly always less expensive and much easier on you than an emergency one during the first heat wave of summer.

The sooner you call about a comfort problem, the smaller the repair tends to be. A weak capacitor is an easy, low-cost part 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 in your contacts today so help is one call away as soon as something sounds or feels wrong in your home. A quick call saves time, money, and sleepless nights.

Common HVAC Problems in San Antonio

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 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. All of them start small, and all of them cost less to fix early. If your system is acting up, call (469) 423-7181 before the season turns it into an emergency.

The Reason San Antonio Keeps Calling Us

Plenty of companies will sell you a new HVAC system. Dallas HVAC earns trust around here by fixing the ones that don't need replacing and being honest about the ones that do. We find the actual fault before we quote a dollar, explain your options in plain language with real numbers, and leave the decision to you. When replacement is the right call, we size the new system with a proper load calculation for your home's genuine demand, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's on the truck.

The workmanship holds up because we sweat the details: correct refrigerant charge weighed in rather than guessed, sealed duct connections, proper condensate drainage, verified combustion and airflow on heating equipment, and clean electrical work that passes inspection without drama. We arrive when we said we would, protect your floors, haul away the old equipment, and test the full system in every mode before we pack up. It's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.

Your HVAC Questions Answered

In many cases, yes. Ductless mini-splits shine in additions, garages, sunrooms, and older homes that were built without ducts. Our approach starts with sizing each zone to the actual room, followed by careful placement of the indoor and outdoor units and a proper install of the line set, condensate drainage, and electrical connections. If central equipment is the better fit for your layout, we'll let you know.
Most repairs fall between $150 and $650 depending on the part and system type, while full system replacements usually run from around $5,000 to $12,000 installed, depending on size and efficiency. Every job starts with a diagnostic and a written, upfront quote. The price you approve is the price you pay, with no surprise line items.
First, rule out the simple causes. Confirm 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 without running means it's time to shut the system off, since continuing to run it can damage the compressor. Call us at (469) 423-7181 and we'll send a technician your way right away.
Yes. We repair all major brands of air conditioners, furnaces, heat pumps, and ductless mini-splits. When a system is past repair, 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 deciding.
Usually the same day. No-heat and no-cooling calls jump ahead of routine maintenance, and we'll tell you an honest arrival time as soon as you call (469) 423-7181. Once our technician arrives, the common failure parts are already on board, so most problems are fixed during that first visit.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit focuses on cooling: cleaning the coils, verifying the refrigerant charge, testing the capacitor, and measuring airflow. The fall visit covers heating: burner cleaning, a combustion check, and safety control testing. Keeping up with both visits extends equipment life, helps prevent breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in energy savings.
We work on nearly every brand installed in local homes, from Carrier, Trane, and Lennox to Rheem, Goodman, and York, as well as ductless systems from Mitsubishi, Fujitsu, and LG. Universal parts on the truck cover most units, and when a repair needs a brand-specific component, we can source it quickly.
There isn't one magic number, but some guidelines help. Most part failures on systems under about 10 years old are worth repairing. After roughly 15 years, or after a failed compressor or cracked heat exchanger at any age, a replacement usually comes out ahead, and newer equipment brings real efficiency gains. We'll give you both numbers up front and let you decide, because we'd rather earn your trust than sell you a system early.
