Complete Guide to Heating Contractor Services
Professional Heating Contractor Expertise
A-OK Services employs certified heating technicians with extensive training on all major furnace brands and heating systems. Our Texas HVAC contractor license (TACLA29221C) demonstrates our commitment to professional standards and legal compliance. Every technician passes background checks, drug testing, and ongoing technical training to stay current with the latest heating equipment and diagnostic techniques. We invest in professional-grade tools, combustion analyzers, and leak detection equipment to ensure accurate diagnosis and quality repairs.
Residential Heating Services
Our residential heating services cover all aspects of home comfort. We repair and install gas furnaces (natural gas and propane), electric furnaces, heat pumps (ducted and ductless), dual-fuel systems, and package units. Services include emergency furnace repair (24/7 availability), annual maintenance tune-ups, complete heating system replacement, ductwork design and modification, thermostat upgrades (programmable and smart thermostats), indoor air quality improvements, and energy efficiency audits. We size heating equipment using Manual J load calculations to ensure proper capacity—neither oversized (which wastes energy and causes short-cycling) nor undersized (which can't maintain comfort during cold weather).
Commercial Heating Solutions
Our commercial heating contractor services support San Antonio businesses, restaurants, offices, retail stores, and industrial facilities. We service rooftop package units, commercial boilers, radiant heating systems, large-capacity furnaces, and specialized heating equipment. Commercial services include preventive maintenance contracts, emergency repair response, building automation integration, compliance inspections, and planned equipment replacement. We understand the critical nature of commercial heating—a breakdown during business hours means lost revenue, customer complaints, and employee discomfort. Our commercial clients receive priority emergency response and customized maintenance schedules to minimize downtime.
San Antonio Winter Heating Considerations
San Antonio's subtropical climate means heating systems operate less frequently than in northern regions, but they're still essential for comfort and safety during cold snaps. Average winter lows range from 40-50°F, but occasional hard freezes can drop temperatures into the 20s or teens. Because heating systems aren't used daily, homeowners sometimes neglect maintenance—then discover problems when they first turn on heat in late fall. Common San Antonio heating issues include: furnaces that won't ignite after months of inactivity, pilot lights that won't stay lit in wind or drafty conditions, ductwork air leaks that waste energy, and undersized heating equipment in older homes. We recommend annual pre-winter heating inspections in October/November to catch problems before you need heat.
Importance of Regular Heating Maintenance
Annual furnace maintenance is crucial for safety, efficiency, and reliability. Heating systems produce combustion byproducts (including carbon monoxide) that must be properly vented. Cracked heat exchangers, blocked flues, or backdrafting conditions can introduce dangerous gases into your home. Our maintenance inspections include carbon monoxide testing and heat exchanger inspection to protect your family. Maintenance also prevents expensive breakdowns—we routinely find worn blower motors, faulty limit switches, corroded flame sensors, and failing capacitors during tune-ups. Replacing these components proactively (during scheduled maintenance) costs far less than emergency repairs on a cold night. Additionally, clean burners, calibrated thermostats, and properly adjusted airflow improve efficiency by 10-15%, reducing heating costs.
24/7 Emergency Heating Service
Heating emergencies don't follow business hours. When your furnace fails at midnight during a January cold snap, you need immediate help. A-OK Services provides 24/7 emergency heating service for San Antonio and surrounding areas. Our emergency technicians arrive with fully stocked service vehicles containing common furnace parts, enabling most repairs to be completed the same visit. Emergency heating situations we handle include: no heat (furnace won't start), furnace cycles on and off constantly, strange noises from furnace (banging, squealing, rumbling), smell of gas near furnace (we shut off gas and identify leaks), and carbon monoxide detector alarming (we test for CO and locate source). We prioritize safety first—if we detect dangerous conditions, we'll explain the situation clearly and recommend the safest course of action.
Warranty Coverage & Quality Assurance
All heating equipment we install includes manufacturer's warranties—typically 5-10 years on parts and heat exchangers. Extended warranty options are available for additional protection. Our installation workmanship is guaranteed—if any issue arises from our installation work, we'll correct it at no charge. For repairs, we warranty parts and labor for 90 days to one year depending on the component. We only install quality heating equipment from reputable manufacturers with proven reliability and local parts availability. Our goal is heating systems that deliver years of trouble-free operation, not callbacks and repeat repairs.
Choosing the Right Heating Contractor
Selecting a heating contractor is an important decision. Look for: valid HVAC contractor license (Texas requires TACLA certification), liability insurance to protect your property, transparent pricing with written estimates, technicians who explain problems and solutions clearly, emergency service availability, positive customer reviews and references, and fair pricing without high-pressure sales tactics. A-OK Services meets all these criteria. Our license (TACLA29221C), insurance, 4.7-star rating, and commitment to honest service make us the heating contractor San Antonio residents trust. We never pressure customers into unnecessary equipment replacements—if your furnace can be repaired affordably and safely, we'll recommend repair. When replacement makes sense, we explain why and present options at different price points.

Heating Contractor FAQs
How much does furnace repair cost in San Antonio?
Furnace repair costs range from $150-$600 depending on the problem. Simple fixes like replacing a flame sensor or thermostat cost $150-$300. Blower motor replacement runs $300-$600. Heat exchanger replacement or complex repairs cost $500-$1,200. We provide upfront pricing before starting work—no surprise charges.
Should I repair or replace my furnace?
Generally, repair makes sense if: furnace is less than 10-12 years old, repair cost is less than half the replacement cost, and major components (heat exchanger, blower motor) are still in good condition. Replace if: furnace is 15+ years old, repair costs exceed $800-$1,000, heat exchanger is cracked, or you're experiencing frequent breakdowns. We'll provide honest recommendations based on your specific situation.
Why won't my furnace turn on?
Common causes include: thermostat set incorrectly or battery dead, circuit breaker tripped or furnace switch turned off, gas supply valve closed (gas furnaces), dirty flame sensor preventing ignition, failed ignitor or pilot light out, clogged air filter restricting airflow, and failed blower motor or control board. Our technicians diagnose the exact cause quickly and get your heat working again.
How often should I have furnace maintenance?
Annual furnace maintenance is recommended every fall before heating season (October or November). Regular maintenance prevents unexpected breakdowns, improves efficiency by 10-15%, extends equipment lifespan by years, maintains manufacturer warranty coverage, ensures safe operation and carbon monoxide testing, and costs far less than emergency repairs. Most furnace tune-ups take 1-2 hours.
Do you provide emergency heating service?
Yes! A-OK Services provides 24/7 emergency furnace repair service throughout San Antonio and surrounding areas. If your heating fails at night, on weekends, or during holidays, call (210) 501-9445 immediately.

What furnace brands do you service?
We service and repair all major furnace brands including Carrier, Trane, Lennox, Rheem, Goodman, American Standard, York, Heil, Amana, Payne, Bryant, Ruud, and more. Our technicians receive factory training on most brands and stock common parts for faster repairs. We can service your furnace regardless of who installed it originally.
How long does furnace installation take?
Standard furnace replacement (same location, existing ductwork): 4-6 hours. Complete heating system installation with ductwork modifications: 1-2 days. Heat pump installation: 1-2 days depending on system type. Installation includes removing old equipment, installing new furnace, connecting gas/electrical, installing/upgrading thermostat, testing system operation, and explaining operation.
