Magnum Heating & A/C is a heating and cooling contractor serving Converse and the surrounding Bexar County area. Whether you own a home in Converse, manage a commercial property across the county, or just need someone who knows this area's climate and can get your system running again, we handle the full range of residential and commercial HVAC work. Local means we care what the neighbors think of our work. Call us for a quote on any heating or cooling job, and we will walk you through exactly what the work involves before anything gets scheduled.
We protect your home. We service your system. We earn the call.
We've handled everything from a quick tune-up to a full system swap, and the work covers both sides of the heating-and-cooling equation. For homeowners, that means AC repair, furnace repair, heat pump service, ductwork sealing, thermostat installation, and indoor air quality work. For commercial clients, it means the same range of services applied to office buildings, retail spaces, restaurants, and multi-unit properties throughout Bexar County.
Every job is carried out by qualified HVAC technicians who know how these systems are built, how they fail, and what it takes to bring them back to spec. Whether the call is about uneven temperatures room to room, an AC that stopped cooling, a furnace blowing cold air, or a system that simply will not turn on, we diagnose the problem and explain what the fix involves before any work begins.
Code-compliant HVAC work on every job is not a tagline. It is how the work gets done, because shortcuts in sizing, installation, or refrigerant handling create problems that show up later. We do it right the first time. Your system is in good hands with us.
Converse sits in Bexar County, where summer is the dominant season and the AC carries most of the load. Temperatures climb into the upper 90s and stay there for months, which means a system that is undersized, low on refrigerant, or overdue for service will struggle before August is over. Sizing matters here. An air conditioner that is too small for the square footage cannot keep up on the hottest days. One that is too large short-cycles, wears out faster, and leaves the air feeling clammy rather than comfortable.
Winter cold snaps do arrive in this part of Texas, and when the temperature drops unexpectedly, a furnace or heat pump that has not been serviced becomes a problem fast. We account for both seasons when we size, install, or service a system. The goal is a home or building that stays comfortable in July and in January, without the system working harder than it has to.
That understanding of the local climate shapes how we approach every job, from a seasonal tune-up to a full system replacement.
Air conditioning is the critical system in this part of Bexar County, and when it stops working, the call needs to happen quickly. We handle AC not working, AC blowing hot air, air conditioner not cooling, refrigerant leak diagnosis, condenser and compressor service, and evaporator coil cleaning. A service visit covers a full diagnostic so you know exactly what failed and what it takes to fix it.
We treat your home and its system the way we would our own. That means we do not recommend a replacement when a repair is the right answer, and we do not patch something that genuinely needs to be replaced. When a full AC replacement makes more sense, whether because of age, efficiency, or the cost of repeated repairs, we handle the installation from start to finish.
Same-day AC repair is often available, and we take emergency calls during our published hours. If the AC is out in the middle of summer, do not wait. Call for an AC repair estimate and we will get someone out.
Winters in Bexar County are mild compared to the rest of the country, but cold snaps arrive without much warning and a furnace that is not working becomes an urgent problem overnight. We handle furnace not working, furnace blowing cold air, no heat in the house, air handler and blower service, and full furnace diagnostics.
A furnace tune-up before the cold season is the most straightforward way to avoid a breakdown in the middle of a cold night. We clean the components, check the controls, confirm the system is firing correctly, and flag anything that looks like it could cause trouble before it does. When a furnace is past the point of repair, we handle furnace replacement and new furnace installation as well.
Code-compliant HVAC work on every job means the installation meets the manufacturer's specifications and the applicable codes for this area. Same-day furnace repair is often available during our business hours, and emergency heating calls are taken every day from 9:00 AM to 9:00 PM.
Heat pumps are a practical fit for the Bexar County climate. In a region where winters are mild and summers run long, a heat pump handles both heating and cooling efficiently without the fuel costs of a gas furnace. We handle heat pump repair, heat pump installation, heat pump replacement, and heat pump tune-ups for both residential and commercial properties.
Ductless mini-split systems are a strong option where adding ductwork is not practical, whether that is a room addition, a converted garage, a commercial space with unusual layout, or a home where the existing duct system does not reach. We handle mini-split installation, mini-split repair, and ductless heating and cooling for any size space. Zoning and comfort-control systems let different areas of a building run at different temperatures, which is useful for commercial clients managing large or unevenly loaded spaces. Call and we'll handle the furnace, the AC, and the ductwork.
Leaky ductwork is one of the most common reasons a system that tests fine on paper still fails to keep a home comfortable. When ducts are poorly sealed or damaged, conditioned air escapes before it reaches the rooms that need it. In a climate where the AC runs hard for months, that inefficiency adds up. We handle leaking ductwork repair, duct sealing, ductwork installation, and full ductwork replacement when the existing system is too far gone to seal effectively.
A thermostat that is not reading correctly, not communicating with the system, or simply too old to do what you need costs you comfort and efficiency. We handle thermostat installation, smart thermostat installation, programmable thermostat installation, and thermostat replacement. A smart thermostat that responds to your schedule and adjusts automatically is one of the more straightforward upgrades available, and we handle the installation and setup so it works correctly from day one.
In a region with high heat, seasonal dust, and extended periods when the windows stay closed, what circulates through the air system matters. We install air filtration systems, whole-home air purifiers, and whole-home humidifiers and dehumidifiers sized for the space. HVAC work sized and installed the way the manual calls for applies here as much as it does to the equipment itself. An undersized filtration system does not do the job. We confirm the right fit for your home or building before the install.
Calling an HVAC company doesn't have to be stressful, and a maintenance visit is the least stressful version of the call. We handle seasonal HVAC maintenance, spring AC tune-ups, fall furnace tune-ups, annual HVAC inspections, and preventive maintenance for both residential and commercial systems. A tune-up visit covers a check of the full system: cleaning components, confirming refrigerant levels, testing controls, inspecting the heat exchanger or coil, and identifying anything that is wearing down before it becomes a breakdown.
We check the furnace. We check the AC. We leave it running right.
Seasonal maintenance is the most straightforward way to avoid an emergency call in the middle of a Texas summer or a January cold snap. Call to schedule a tune-up and we will confirm what the visit covers and what it costs before you book.
Property managers trust us to keep their buildings comfortable, and that means being specific about what commercial HVAC work involves. We handle commercial HVAC repair, commercial HVAC service, commercial HVAC installation, commercial HVAC maintenance, and commercial HVAC replacement for office buildings, retail spaces, restaurants, and multi-unit residential properties throughout Bexar County.
Commercial clients need reliable scheduling and clear pricing, and we work to provide both. You get the rate on the call, before anything is scheduled, and the quote covers what the job involves. Qualified HVAC technicians handle the work, and zoning and comfort-control systems are part of what we install and service for larger commercial spaces. Let us handle the install and the permits.
When you call, the scope and the price are settled before anything is scheduled. We ask about the system, the symptoms, and the property, and we give you a clear number that covers what the job involves. There is nothing to figure out after the fact. The same number that books the job is the number to call if you have questions afterward.
We do not send someone out and then present a bill that looks different from what was discussed. The price is confirmed before we schedule, and you are told what it covers. If the scope changes once a technician is on site and finds something additional, that conversation happens before the additional work begins. Ask what the quote covers and you get a straight answer.
When the heat or the AC quits, the call should be easy to make. We handle emergency HVAC repair, emergency AC repair, emergency furnace repair, and same-day HVAC service for Converse and the surrounding Bexar County area. An AC that stops working in July or a furnace that goes out on a cold January night is not a situation to wait on.
We are available every day from 9:00 AM to 9:00 PM. Same-day service is often available, and emergency calls are answered during those hours. When your system is down and the house is not cooling or heating, call us and we will get a qualified technician out to diagnose and address the problem. We're one phone call from getting your comfort right.
HVAC repair cost, replacement cost, and installation cost are questions we answer on the call, not after the work is done. Whether the job is an AC repair, a furnace repair, a heat pump replacement, or a new HVAC system installation, you get a clear rate before anything is scheduled.
Pricing is explained up front and covers what the job involves. We do not quote one number and present another. If you want to know what AC repair costs in Converse, or what a new heat pump installation runs for a home your size, call and ask. The answer is a specific number, not a range designed to leave room for adjustment later.
We serve Converse and the wider Bexar County area, including Universal City, Schertz, Live Oak, Kirby, Selma, and San Antonio. If your home or commercial property sits in or around Converse, we can get a technician out to you.
The service area covers the full range of Bexar County communities, and we handle both residential and commercial calls across the region. Whether the property is in a newer subdivision on the edge of Converse or a commercial building closer to central San Antonio, the same qualified technicians and the same pricing process apply.
Converse sits in a climate where the cooling season runs long and hard, and the housing stock reflects that. We know that an undersized system in this part of Bexar County will struggle before August is over, and that a heat pump sized correctly for this area handles both heating and cooling without the fuel costs of a furnace-only setup. That understanding of the local climate shapes how we size, install, and service equipment, from a quick repair to a full system replacement.
If something does not feel right after the work is done, call us at (830) 590-9782 and describe what you are seeing. We will talk through the symptoms and determine whether a follow-up visit is needed. We do not consider the job finished until the system is doing what it is supposed to do.
Code-compliant HVAC work is the standard on every job, whether that is a repair, a replacement, or a new installation. Where permits are required for the work being done, we handle that process as part of the job. You do not need to manage the permitting side on your own.
We treat your home and its system the way we would our own, and that includes how we leave the space when the work is done. Technicians clean up after themselves and do not leave the property in worse shape than they found it. If the job involves ductwork, attic access, or equipment removal, we account for that in how we set up and wrap up the work.
When you book a call, we confirm what is available and give you a window for the visit. You are told what to expect before the technician arrives. We do not make promises about an exact arrival time, but we communicate clearly about the schedule and let you know if anything changes.
It starts with a clear quote on the call before anything is scheduled, and it carries through to the technician explaining what was found and what was done before leaving the property. If the scope changes once the technician is on site, that conversation happens before any additional work begins. The goal is that you know what happened and why, not just that the system is running again.
HVAC diagnostics and installation depend on accurate readings: refrigerant levels, airflow measurements, temperature differentials, and electrical controls all require the right instruments to assess correctly. A technician working with the proper tools identifies the actual problem rather than guessing at it. That is the difference between a repair that holds and one that comes back.
We schedule jobs in a sequence that allows adequate time for each one, so a job that runs long on one property does not leave the next customer waiting without communication. If something shifts during the day, we work to keep customers informed. The goal is that every job gets the attention it needs, not a rushed visit to stay on a tight clock.
Local means we care what the neighbors think of our work. When a technician services a home in Converse or a commercial property in Bexar County, the quality of that work reflects on every future call in the same area. That accountability shapes how the job gets done, from the diagnosis through the cleanup.
Magnum Heating & A/C handles the full range of heating and cooling work for Converse and Bexar County, from a seasonal tune-up to a full system replacement. When your AC stops cooling, your furnace stops heating, or you are ready to upgrade to a more efficient system, the call is straightforward.
