Something stops working and the house tells you immediately. The air feels wrong, a room that should be comfortable is not, or the system runs and runs without making any difference. Most of the time there is a diagnosable reason, and finding it is where the job starts. Magnum Heating & A/C handles that work for Timberwood Park homes and properties, from the first call through to a running system.
We cover the full range of heating and cooling work: repairs, replacements, maintenance, and upgrades. Whether the call comes from a homeowner whose furnace has not fired up, a landlord dealing with a unit that has no cooling, or a property manager keeping a building comfortable through a long South Texas summer, we handle it the same way. Call (830) 590-9782 and we will confirm pricing before anything is scheduled.
The rate depends on what the job actually turns out to be. A straightforward repair on an accessible component lands differently than a full system replacement, and the quote reflects the real scope once we know what we are dealing with. What moves a number is the nature of the fault, how much of the system has to be reached to address it, and whether repair is the right call or whether the equipment has reached the point where replacement makes more sense.
When you call, we ask about the system and the symptoms. From there we give you the rate before we schedule, so you know what the visit covers and what it costs. There are no figures that appear after the fact. The price is confirmed on the phone, and the technician explains the scope in full before any work begins.
Calling an HVAC company doesn't have to be stressful, and the pricing conversation is a good example of why. You get a straight answer on the call, and you decide from there.
Same-day service is often available for urgent situations. A home with no cooling during a stretch of intense summer heat, or no heat when temperatures drop, is not a situation to leave for a routine appointment slot. We take those calls every day from 9:00 AM to 9:00 PM and move them to the front of the line when same-day appointments are open.
For properties with tenants or a business that has to stay open, we work around the situation. We confirm what is available when you call, and we communicate clearly about timing so the people on site know what to expect. We do not make promises about arrival windows, but we tell you what we know and we keep you updated.
Affordable rates. Flexible timing. Reliable comfort.
For what the job actually entails, the page covering HVAC work lays it out.
When a system reaches the end of its life, the natural instinct is to replace it with something the same size. That instinct is wrong more often than it is right. A system installed years ago may have been oversized or undersized from the start, or the property may have changed since then. Additions, insulation upgrades, window replacements, and changes in how the space is used all affect what the new equipment needs to do.
We size replacements to match the actual load the property puts on the system, not the nameplate on the old unit. HVAC work sized and installed the way the manual calls for means the new system runs efficiently, reaches the set temperature without short-cycling, and does not wear itself out by fighting a load it was never designed for.
This matters more in a climate that demands real cooling for months on end. A system that is too large for the space cools quickly but does not run long enough to pull humidity out of the air, and in this region that is a comfort problem even when the thermostat reads correctly.
Timberwood Park is a city with a mix of established homes and newer construction, and the HVAC work those properties generate is not all the same. A well-maintained newer home with a properly sized system calls for something different than a home where the original equipment has been running hard for years without a thorough inspection. Understanding the difference shapes how we approach the job.
Poor airflow is one of the more common complaints we hear, and the cause is rarely just a dirty filter. Collapsed duct sections, a failing blower motor, a blocked evaporator coil, or an air handler that has never been properly serviced can all produce the same symptom. We trace the problem back through the system rather than treating the vent as the issue.
A cracked or compromised heat exchanger is a safety concern, not just a performance one. We inspect heat exchangers as part of furnace service and flag anything that warrants attention before the heating season puts the system under full load. This is the kind of check that matters most on older equipment that has not been regularly maintained.
Heat pumps can develop faults on either the heating or the cooling side, and defrost cycle problems are a specific failure mode that affects performance when outdoor temperatures drop. We diagnose heat pump faults across both modes and address defrost control issues, refrigerant problems, and reversing valve failures that cause the system to underperform or stop working entirely.
Uneven temperatures from room to room are often a duct and register problem rather than an equipment problem. We assess airflow distribution, adjust dampers and registers, and identify sections of the duct system that are delivering too much or too little to the spaces they serve. Paired with air handler and blower service, rebalancing can make a significant difference in how evenly a home holds temperature.
A system that simply will not turn on can point to a failed capacitor, a tripped safety switch, a thermostat that has lost communication with the unit, a contactor fault, or a compressor that has failed. We work through the diagnostic systematically so the repair addresses the actual cause. A system that will not start in the middle of summer is an urgent call, and we treat it as one.
A location page cannot carry the full detail of every job type. The service page holds that breakdown. What it can do is describe the situations that lead to a call, because those are what a homeowner or property manager actually experiences.
The call that comes in most often is a system that has stopped doing what it should. It may have quit entirely, or it may be running without producing the result it used to. Diagnosis is where the job starts: finding the fault, explaining what it means, and confirming the repair before anything is touched. We treat your home and its system the way we would our own, which means we do not skip the diagnostic to get to the invoice faster.
A seasonal tune-up is the call that prevents the urgent one. We inspect, clean, test, and calibrate across both the heating and cooling sides of the system, and we flag anything that is heading toward a problem before it becomes a breakdown. For properties with tenants, a working system that has been properly maintained is worth considerably more than one that fails during a heat wave. We check the furnace. We check the AC. We leave it running right.
When repair costs stack up or the system can no longer hold the temperature the property needs, replacement is the right conversation to have. We walk through the options, size the new equipment correctly, and handle the installation. Where permits apply to the work, we handle that process as part of the job. The service page carries the full breakdown of what installation involves and what to expect on the day.
The technician arrives, reviews what was reported, and begins a full assessment of the system before recommending anything. That means checking the components most likely to produce the reported symptoms and working outward from there, not starting with the most expensive repair and working backward.
Before any work is agreed to, the technician explains what the diagnostic found, what the recommended repair or replacement involves, and what it will cost. You decide from there. Code-compliant HVAC work on every job means the repair meets the applicable requirements, and nothing is done without your agreement on the scope.
Nothing is rushed. Local means we care what the neighbors think of our work, and that shows up most clearly in the conversation before the work begins.
We handle HVAC calls throughout Timberwood Park and the surrounding communities in Bexar County. That includes Bulverde, Hollywood Park, Hill Country Village, Shavano Park, and Fair Oaks Ranch. If your property is in the area and you are not sure whether we reach your address, call and we will confirm.
We serve residential homeowners, landlords, and commercial properties across the area. The same approach applies regardless of the size of the job or the type of property.
Established homes in this part of Bexar County tend to generate calls around aging equipment running past its useful life, ductwork that was never properly sealed or balanced, and systems that have not had a thorough inspection in years. Heat pump faults and humidity-related comfort problems are also common in this region, particularly during the long cooling season. A diagnostic call is the fastest way to find out what is actually going on with your specific system.
A system in a vacant property still benefits from a check before it is needed again. Equipment that has been sitting idle can develop issues that are not obvious until the system is asked to run. A pre-occupancy tune-up is a practical step before the property is used again, particularly after an extended vacancy.
We can discuss how to structure service across multiple addresses when you call. Whether that means scheduling the visits together or consolidating the paperwork is something we work out based on the properties involved and what is practical for the day.
We work with the schedule that fits the property. When you book, let us know the access situation and any constraints around the tenant's availability. We are available every day from 9:00 AM to 9:00 PM, which gives us flexibility to find a window that works.
It depends on the job and the time of year. A repair call is usually completed quickly enough that comfort is not significantly affected. A full system replacement takes longer, and on a hot day the interior will warm up while the equipment is disconnected. We work efficiently to minimize the time the system is out, and we let you know what to expect before the job starts.
We walk through both options clearly when the diagnostic points to a decision between repair and replacement. We explain what the repair involves, what it costs, and what the remaining life of the equipment looks like so you have what you need to make an informed call. If you need that in writing for a property file or an owner approval, let us know.
A smart thermostat can usually be installed on an existing system as long as the wiring supports it. Most modern HVAC systems are compatible with current smart controls. We check compatibility before installation and confirm the new control is communicating correctly with the system before we leave.
The scope of the job and the equipment involved both affect the quote, and property size is part of that picture. A larger home with more conditioned space requires equipment sized to match, and a replacement quote for a larger property will reflect that. When you call, we ask the right questions about the property and the system so the estimate we give you is based on what your job actually involves, not a generic figure.
Turn the system off and call us. A brief burning smell when the heat first comes on in fall can be dust burning off the heat exchanger, and it often clears on its own. A persistent burning smell, or one that appears unexpectedly, points to something that should be inspected before the system runs again.
