When the heat breaks in July or the furnace quits in January, Converse homeowners and business owners need a straightforward answer: who shows up, what does it cost, and when can they get here. Magnum Heating & A/C handles the full range of residential and commercial HVAC work across Converse and Bexar County, from a quick repair call to a full system replacement. We protect your home. We service your system. We earn the call.
Whether you manage a single-family home, a rental property, or a commercial building, we handle the heating and cooling work from start to finish. Call (830) 590-9782 for a quote and we will confirm pricing before anything is scheduled.
We've handled everything from a quick tune-up to a full system swap, and the work is always the same: show up, diagnose it right, and fix what needs fixing. We cover AC repair and service, furnace repair and service, heat pump repair and installation, full system installation and replacement, thermostat and smart-control installation, ductwork repair and sealing, indoor air quality and air filtration, and seasonal maintenance.
We treat your home and its system the way we would our own. That means we look at the whole picture, not just the part that called for attention, and we tell you what we find before we do anything.
Your system is in good hands with us.
A central air system that stops cooling or starts blowing warm air usually has a diagnosable cause. We check refrigerant levels and look for leaks, inspect the condenser and compressor, clean the evaporator coil, and test the air handler and blower to make sure airflow is moving the way it should. Uneven temperatures from room to room are often a sign that something upstream needs attention, and we trace those problems back to the source.
Same-day service is often available for AC repairs in Converse, particularly during the stretch of summer when a broken system is not a minor inconvenience. When you call, we confirm the rate before anything is scheduled so you know what you are looking at.
For a full central air installation or replacement, we size the equipment to the home, handle the installation, and walk you through what was done. Call and we'll handle the furnace, the AC, and the ductwork.
Calling an HVAC company doesn't have to be stressful, even when the furnace quits on a cold morning. We handle furnace repair when the system will not turn on, when it runs but blows cold air, or when it cycles on and off without heating the space. We also perform seasonal furnace tune-ups and inspections before the cold months arrive, which is the best time to catch a problem before it becomes an urgent one.
We perform code-compliant HVAC work on every job, whether that is a repair call or a full furnace replacement. When a heating system has reached the point where repair no longer makes sense, we walk through the replacement options, size the new unit correctly, and handle the installation.
Pricing is explained on the call. We give you the estimate before we schedule, not after. We're one phone call from getting your comfort right.
Heat pumps handle both heating and cooling from a single system, which makes them a practical fit for the South Texas climate where winters are mild and the cooling load carries most of the year. We service heat pumps that are not heating or not cooling, perform heat pump tune-ups and maintenance, and handle heat pump installation and replacement when it is time to upgrade.
Mini-split and ductless systems fall under the same umbrella. Whether you are adding a zone to a room that does not connect to the central duct system or replacing an older unit, we handle the installation and the ongoing service. Zoning and comfort-control upgrades are a natural extension of this work, and we can walk through the energy-efficiency side of the conversation when you call.
Let us handle the install and the permits.
Converse sits in a climate that asks a lot from HVAC equipment. Summers in Bexar County run long and hot, humidity builds through the warmer months, and while winters are mild compared to most of the country, the cold snaps that do arrive still require a reliable heating system. The work that comes up most in this area reflects that combination: aging systems pushed hard through summer heat, a growing shift toward heat pumps, and humidity that creates comfort problems even when the thermostat reads correctly.
A repair makes sense when the equipment is relatively new and the cost is reasonable. When a system is running old, losing efficiency, and breaking down during the hottest weeks of the year, replacement is usually the better answer. We assess the equipment, size the replacement correctly for the home or building, and handle the installation with HVAC work sized and installed the way the manual calls for. On the day of installation, we walk through what was done and what to expect going forward.
South Texas winters rarely push a heat pump to its limits, which means the heating side of the equation is almost never the bottleneck. The real case for a heat pump here is the cooling efficiency it delivers across the long summer. We assess the home, confirm the right equipment for the load, and handle the installation from site visit through startup. When you call for a quote, we explain what the process involves and what you can expect on installation day.
Bexar County humidity creates a specific kind of discomfort: the thermostat says 75 degrees but the air feels heavier than it should. A portable dehumidifier handles one room. A whole-home dehumidifier integrates with the existing HVAC system and controls moisture across the entire house, running automatically without requiring the air conditioner to do all the work. We handle humidifier and dehumidifier installation as part of a broader indoor air quality conversation, and we can walk through the options when you call.
Property managers trust us to keep their buildings comfortable, and a big part of that comes down to the controls and the delivery system. Smart thermostat installation, whether that is a Nest, an Ecobee, or a comparable programmable control, is a straightforward upgrade that gives you better visibility into how the system is running. When an existing thermostat stops responding or starts behaving erratically, we replace it and confirm the new one is communicating correctly with the system.
Leaky ductwork is one of the more common reasons a system runs longer than it should without reaching the set temperature. We inspect ductwork, seal leaks, and repair sections that have come loose or deteriorated. HVAC work sized and installed the way the manual calls for includes the delivery side, not just the equipment.
On the air quality side, we install air purifiers, UV air purifiers, air filtration systems, and air scrubbers that work alongside the existing system to reduce particulates, allergens, and airborne contaminants. Call and we'll handle the furnace, the AC, and the ductwork.
A maintenance visit before the summer peak or before the first cold snap is the most cost-effective HVAC call you can make. We check the furnace. We check the AC. We leave it running right.
During a tune-up, we inspect the heat exchanger, test ignition, check refrigerant levels, clean coils, test the blower and airflow, calibrate the thermostat, and flag anything that looks like it is heading toward a problem. We handle residential maintenance for single-family homes and commercial maintenance for larger buildings and multi-unit properties alike.
Pricing is confirmed on the call before anything is scheduled. We're one phone call from getting your comfort right.
Office managers, retail operators, apartment building owners, and property managers all have the same basic need: a heating and cooling system that works reliably and does not interrupt the business. We handle commercial AC repair, commercial heating repair, commercial HVAC installation and replacement, and ongoing commercial maintenance across Converse and the wider Bexar County area.
Work is performed by qualified HVAC technicians who understand commercial equipment and the expectations that come with a business environment. Local means we care what the neighbors think of our work, and that applies whether the job is a residential tune-up or a rooftop unit on a commercial building. Your system is in good hands with us.
When the heat or the AC quits, the urgency is real. A home without cooling in a Texas summer or without heat on a cold night is not a situation to leave until next week. We take emergency calls for no-heat and no-AC situations, urgent system failures, and breakdowns that cannot wait for a routine appointment.
Same-day service is available for emergency calls. We are available every day from 9:00 AM to 9:00 PM. When you call, we confirm pricing before we schedule and we tell you what to expect. We do not make promises about arrival windows, but we move emergency calls to the front of the line.

Call (830) 590-9782 and we will ask about the system, the symptoms, and the property. From there we give you a clear rate before anything is scheduled, so you know what the job covers before we send anyone out. There is nothing to figure out after the fact.
Same-day service is often available, particularly for urgent repairs during the summer cooling season or a cold-weather heating failure. When you call, we confirm what is available and let you know when someone can be out. Emergency calls are prioritized during our hours, every day from 9:00 AM to 9:00 PM.
Yes. We are available every day from 9:00 AM to 9:00 PM, including Saturday and Sunday. If the system goes down over the weekend, call (830) 590-9782 and we will work to get someone out the same day when appointments are available.
It helps to know the make and model of your system if that information is accessible, along with a description of the symptoms: what the system is doing, when it started, and whether it has happened before. If you have had recent service or repairs, that information helps us understand the full picture. None of it is required to get a quote started, but it speeds things up.
We confirm the pricing and the scope of the job before anything is scheduled, so you know exactly what the visit covers. A qualified HVAC technician comes to the property, diagnoses the problem, and explains what the fix involves before any work begins. If the scope changes once the technician is on site, that conversation happens before any additional work is done.
We work with your schedule when possible. When you call, let us know what windows work for you and we will confirm what is available. We are here every day from 9:00 AM to 9:00 PM, which gives us flexibility to find a time that does not require you to take an entire day off.
The scope of the job and the equipment involved do affect the quote. A repair on a small residential system is priced differently from a full replacement on a large commercial unit. When you call, we ask the right questions to give you a rate that reflects what the job actually involves, not a generic estimate.
Pricing is confirmed before we schedule, and payment is settled at the time of service. We do not present a bill that looks different from what was discussed on the call. If you have questions about what the quote covers, ask on the call and you will get a straight answer.
