Reliable Heating for Texas Cold Snaps
Need a heating contractor in San Antonio when a cold front rolls through? We repair and install furnaces and heat pumps. Pick the service your home needs below.
Furnace
Repair
A furnace that clicks but won’t light usually points to a dirty flame sensor, worn ignitor, or gas fault. We diagnose the ignition safely, walk you through the fix, and back it with a 90-day warranty.
Furnace Installation & Replacement
Cracked heat exchanger or a unit that’s well past its prime? Abel sizes a right-fit furnace for mild local winters. No oversizing that short-cycles and burns fuel, just honest sizing, clear options.
Heating System
Maintenance
Sitting idle through the long cooling season, a furnace can’t be trusted on a cold night without a check. We inspect ignition, airflow, and the filter, then test for carbon monoxide on gas units.
Heat Pump Repair
Cold air in heating mode usually means a stuck reversing valve, a defrost fault, or low charge. We test the valve and defrost controls to pin the real cause, since the unit’s cycles share components.
Heat Pump Installation
Skip running two separate systems. One heat pump heats through every cold snap and cools all summer, so it’s efficient year-round. We size it to your winters and home, then explain the fit up front.
Smart Thermostat Installation
Through mild winters, a smart thermostat schedules heat around your day and keeps rooms even without overworking it. We wire it right, set each stage, and you’ll control your comfort from anywhere.

Heating Questions We Get a Lot
Real Questions. Real Answers.
Wondering whether you need a heating contractor in San Antonio with winters this mild? Plenty of homeowners do, and these answers cover repair, sizing, and safety. Take a look below, then call or text us if your system needs a closer look.
San Antonio winters are mild, so heating demand is low compared to cooling, but cold snaps still hit and most homes here need a working furnace or heat pump for those nights. A reliable heating system matters most during the short stretches when temperatures drop sharply. Aircules services furnaces and heat pumps so San Antonio homes stay safe and comfortable when the cold does arrive.
A furnace that clicks but will not light in San Antonio usually points to a dirty flame sensor, a worn ignitor, a gas-supply issue, or a tripped safety control. Because furnaces here sit idle for much of the year, that first cold-night start is often when a hidden fault shows up. Aircules diagnoses the ignition problem safely and explains the fix before any work begins.
Furnace repair pricing in San Antonio tracks the specific failed part, whether it is a gas or electric system, the age of the unit, and how easy the component is to reach. A flame sensor or ignitor is a smaller job than a gas valve or control board. Aircules diagnoses the real fault first and explains the number in plain English, backed by a 90-day repair warranty.
Because San Antonio winters are mild, a heat pump often handles the heating load efficiently while also serving as the home’s air conditioner, which makes it a practical single system. A gas furnace can still be the right call depending on your existing setup, ductwork, and preferences. Aircules sizes both options to your home and walks through which one fits your comfort and budget.
A quick fall check once a year is enough for most San Antonio homes, since the heating system sits unused through the long cooling season and benefits from a safety look before first use. The visit covers ignition, airflow, the filter, and a carbon monoxide safety check on gas equipment. Aircules uses the tune-up to catch a fault before it leaves you cold on the first chilly night.
A San Antonio furnace that has gone months without running can collect dust on the burners and develop a stuck or dirty ignitor, and gas equipment carries a small carbon monoxide risk if a heat exchanger has cracked. A fall safety check clears most of that before you rely on the system. Aircules inspects the unit and confirms it is safe before the first cold front.
A heat pump blowing cold air in heating mode in San Antonio often points to a stuck reversing valve, a defrost-cycle fault, low refrigerant, or auxiliary heat that is not engaging. These faults need a real diagnosis because the system is running its cooling and heating cycles through the same components. Aircules tests the reversing valve and defrost controls to find the actual cause before recommending a repair.
Furnace sizing in San Antonio should reflect the mild local winters rather than being oversized for a colder region, since an oversized unit short-cycles and wastes fuel. The right capacity comes from the home’s square footage, insulation, ductwork, and layout. Aircules sizes heating equipment to San Antonio’s actual climate so you are not paying for capacity the house will never use.
Warning signs in a San Antonio home include a furnace that will not light, weak or cold airflow, short-cycling, banging or rattling at startup, or a burning smell that lingers past the first run of the season. Because the system sits idle through the long cooling months, the first cold-night start is when most faults appear. Aircules tracks the symptom to its real cause and backs the fix with a 90-day repair warranty.
Replacement usually makes sense in San Antonio when the furnace is well past its expected life, the repair cost is climbing toward the value of the unit, or a gas heat exchanger has cracked and become a safety issue. Mild local winters mean furnaces here often age more slowly than the AC, so many still have life left. Aircules runs the honest repair-or-replace math and only recommends a new system when the numbers support it.
