The hardest part of an HVAC problem is knowing when to call, and most people wait longer than they should. An AC that stopped cooling, a furnace that will not turn on, a heat pump that runs but puts out the wrong temperature, a central air system that trips off mid-afternoon in July. These are the calls we handle, and each one starts the same way: a conversation about what the system is doing, what it stopped doing, and what the visit will cover.
Pricing is given on the call before anything is scheduled. You know the rate before the visit starts, and you know what it covers. Call us and we'll walk you through your options.
No heat and no cool situations move to the front of the line. If a furnace goes out on a cold night or an AC fails when Converse hits triple digits, that is not a problem to sit on. We take emergency heating and cooling calls every day from 7:00 AM to 8:30 PM. When you call, describe what the system is doing and we will tell you what to expect from the visit.
Emergency furnace repair, emergency AC repair, and emergency heat pump service are all on the table.
Call (830) 590-9782 and we will get you on the schedule.
A diagnostic visit starts at the equipment. The technician who comes out checks what the system is actually doing: pressures, temperatures, electrical signals at the control board, airflow through the unit, and the condition of the components most likely to cause the fault. The reason for a fault explained, not just the fix. You find out what went wrong and why before any repair is agreed to.
The diagnostic fee is confirmed on the call. No part of the visit is a surprise.
A home that heats and cools right is a comfortable home, and getting there covers more ground than a single repair call. We handle the full menu of residential and commercial HVAC work, from a quick thermostat swap to a full system replacement, and everything in between.
An air conditioner that blows warm air or short-cycles through the afternoon is telling you something. The visit covers refrigerant pressure checks, condenser and compressor condition, evaporator coil inspection, and airflow through the system. Uneven temperatures from room to room often point to something specific, and the diagnostic narrows it down before parts are quoted.
A furnace that will not ignite, runs but blows cold air, or shuts down before the house reaches temperature needs a systematic check. The visit covers the ignition system, heat exchanger condition, blower motor, and airflow through the cabinet. We confirm what the system is doing before recommending a repair path.
Heat pumps fail in ways that look like other problems: a reversing valve stuck in one mode, a refrigerant charge that is off, a defrost cycle that will not complete, an air handler that runs without moving enough air. The visit covers the full refrigerant circuit and the control side. Whether the system is not heating or not cooling, we start at the unit.
Ductless mini-splits work well in additions, converted garages, and rooms that never got proper airflow from the central system. When one stops cooling or the air handler drips condensate, the visit covers the refrigerant line set, the drain, the indoor head, and the outdoor unit. We also install new ductless systems where adding duct runs does not make sense.
A thermostat that reads the wrong temperature or will not hold a schedule affects the whole system. We replace failed thermostats and install smart controls wired to the low-voltage terminals on the HVAC equipment. If you want a programmable or app-controlled setup, call and we will confirm what your system supports before the visit.
Leaking ducts push conditioned air into attic space or wall cavities instead of into the rooms you are trying to cool or heat. The result is uneven temperatures, higher energy use, and a system that runs longer than it should. Duct sealing and repair covers the accessible runs, the connections at the air handler, and the joints most likely to separate over time.
Whole-home filtration and air purifier installation work with the existing HVAC system to reduce airborne particulates and improve the air moving through the house. We install media filters, electronic air cleaners, and UV systems depending on what the home needs. If indoor air quality is a concern, the call is a good place to start.
A spring AC tune-up before the Converse heat season gets going covers refrigerant charge, coil condition, drain line, and electrical connections at the unit. A fall furnace tune-up covers ignition, heat exchanger, blower, and filter. Catching a worn part in October costs less than replacing a failed one in January. We'll handle the system so you don't have to.
South Texas puts specific demands on heating and cooling equipment. The summers are long and humid, the winters are mild but not absent, and the equipment that handles both needs to be sized and selected for this climate. Doing it properly the first time is the whole point.
When a system reaches end-of-life, replacement is a better call than another repair. In Converse, that usually means a paired furnace-and-AC setup sized for a home that runs cooling for eight or nine months and heating for the rest. The visit covers a load calculation for the space, equipment options that fit the existing infrastructure, and a quote before anything is scheduled. You know what the replacement involves before work starts.
Bexar County's mild winters and long cooling seasons make heat pumps a practical fit for many homes. A heat pump moves heat rather than generating it, which works efficiently when outdoor temperatures stay above freezing most of the winter. Installation covers equipment selection, refrigerant line set, air handler placement, and connection to the low-voltage control wiring at the thermostat. Sizing matters here: an undersized unit runs constantly in July, and an oversized one short-cycles and leaves humidity in the air. We confirm sizing on the call before the visit is scheduled.
Humidity is a persistent comfort problem in this part of Texas. An air conditioner removes some moisture as it runs, but a system that is oversized or one that short-cycles does not run long enough to pull the humidity down. A whole-home dehumidifier installs in line with the existing HVAC system and handles moisture independently of the cooling cycle. The result is a house that feels comfortable at a higher thermostat setting, which also reduces the load on the AC. If the air feels heavy even when the temperature is right, call and we will walk through what the system is doing.
Calling an HVAC company doesn't have to be stressful, and it starts the same way for every customer type. Homeowners, landlords managing rental properties, property managers running apartment complexes, small business owners with a rooftop unit, office buildings that need a commercial system serviced. The scope is confirmed on the call, the visit is scheduled, and the system tested before the visit ends.
We work across light commercial and residential accounts in Converse and the surrounding area. If you manage multiple properties or need ongoing service for a commercial space, call and we will talk through what that looks like.
Your time matters, so we keep the HVAC job moving from the first call. Pricing questions are common, and the honest answer is that the cost depends on what the diagnostic finds. AC repair, furnace repair, heat pump repair, and system replacement all carry different variables: the part, the refrigerant charge, the age of the equipment, the scope of the replacement.
What does not vary is the process. You get the rate on the phone before the visit is scheduled. The diagnostic fee is confirmed upfront. Once the technician identifies the fault, you get a clear explanation of what it is and what the repair involves before any work is agreed to. The HVAC work done properly, start to finish, begins with a price you understand before anyone shows up.
Call (830) 590-9782 and ask what the rate covers. That is where the job starts.
We serve Converse and the communities around it, including Schertz, Universal City, Selma, Live Oak, Kirby, Windcrest, Cibolo, and San Antonio. If you are in Bexar County or the northeast San Antonio metro and need heating or cooling work handled, call and we will confirm your area on the call.
A system that is completely down, no heat in January or no cool in the middle of a Converse summer, is an emergency. So is a furnace that shuts off in the middle of the night and will not restart, or an AC that fails when outdoor temperatures are at their peak. We take emergency calls every day from 7:00 AM to 8:30 PM.
Call (830) 590-9782 and describe what the system is doing.
Warm air from the vents when the thermostat is set to cool, a system that runs constantly without bringing the temperature down, ice forming on the refrigerant lines or evaporator coil, and water pooling near the air handler are all early warning signs. These symptoms usually point to a refrigerant issue, a failing component, or a clogged condensate drain. Catching them before the system shuts down completely is almost always less expensive than an emergency repair.
An AC that runs without cooling is usually dealing with a refrigerant charge that is low, a condenser that is not rejecting heat properly, or an evaporator coil that is frozen or blocked. Any of those can look like a minor issue but indicate a more significant fault underneath. The diagnostic visit checks pressures, temperatures, and airflow to identify where the failure is before a repair path is recommended.
A system that has needed repeated repairs, one that struggles to maintain temperature on hot days, one that makes grinding or rattling sounds from the outdoor unit, or one that runs on refrigerant no longer in production is showing signs of age. These are the situations where the diagnostic conversation moves to whether repair or replacement is the better call. The cost of both options is confirmed before any work is agreed to.
A furnace that will not ignite, one that cycles on and off without reaching the set temperature, one that blows cold air instead of warm, or one that makes a loud noise when it starts up is worth a diagnostic visit. In Converse, heating calls pick up during the cooler months, and a furnace that has not been serviced recently is more likely to develop a fault during a cold stretch. The visit covers the ignition system, heat exchanger, blower motor, and airflow through the cabinet.
Short cycling, where the furnace starts, runs briefly, and shuts off before the house reaches temperature, is usually caused by an overheating heat exchanger, a failing flame sensor, a clogged filter restricting airflow, or a control board fault. The technician checks each of these in sequence during the diagnostic visit. Leaving a short-cycling furnace running without a diagnosis can accelerate wear on the heat exchanger.
The visit covers both. If the equipment is operating correctly at the unit but rooms are uneven or the system runs longer than it should, the ductwork is the next place to look. Leaking ducts push conditioned air into unconditioned spaces before it reaches the rooms, which raises energy use and leaves the system running past the point it should shut off. The diagnostic narrows it down before any repair is recommended.
The outdoor unit inspection covers refrigerant pressures, condenser coil condition, the fan motor and blade, electrical connections at the contactor and capacitor, and airflow through the coil. For heat pumps, the reversing valve and defrost cycle are also checked. These components are common failure points, and checking them during a tune-up catches wear before it becomes a breakdown.
Refrigerant work and outdoor unit installation require conditions that allow the equipment to be properly charged and tested. Extreme heat, rain, or severe weather can affect the timing of outdoor work. If conditions affect the visit, we discuss the options on the call and confirm what the schedule allows. Installation work is scoped with the site conditions in mind.
A repair is the right call when the fault is isolated, the equipment is in reasonable condition, and the cost of the repair is proportionate to the remaining useful life of the system. Replacement becomes the better option when repair costs are stacking up, the refrigerant is no longer available, or the system is too old to be worth the investment. The diagnostic visit covers both options, and you get a straight answer before any work is agreed to.
Permit requirements for HVAC replacement depend on the jurisdiction, the scope of the work, and whether the installation involves changes to the existing setup. Requirements can differ between the city of Converse and the surrounding Bexar County area. We confirm what applies at your address before the work is scheduled, and any required permit is accounted for in the scope of the job.
Someone who can provide access to the equipment needs to be available at the start of the visit. The air handler, furnace, and outdoor unit all need to be accessible, and the technician will need to confirm what was found and what the repair involves before work begins. If your schedule is a concern, call and we will work through the access details when the appointment is booked.
Book the visit. Know the scope. Know the rate.

How often should I schedule a maintenance tune-up for my HVAC system?
For most homes in Converse, two tune-ups a year cover the equipment properly. A spring visit before the cooling season gets going checks refrigerant charge, coil condition, the condensate drain, and electrical connections at the outdoor unit. A fall visit before the heating season covers ignition, heat exchanger condition, blower motor, and filter. Catching a worn part in October costs less than replacing a failed one in January. If the system runs year-round, as most do in this climate, annual service at minimum keeps it from going into a heavy-use season with a problem already developing.
What does a dirty filter or coil actually do to system performance?
A clogged filter restricts airflow through the air handler, which forces the blower to work harder and reduces the volume of air moving across the evaporator coil. When airflow drops far enough, the coil can freeze, which stops cooling entirely and can put strain on the compressor. A dirty evaporator or condenser coil has the same effect from the other direction: the system cannot transfer heat efficiently, so it runs longer to reach the set temperature and uses more energy doing it. Both problems are checked during a tune-up visit.
What does a strange noise from the outdoor unit usually mean?
A grinding or rattling noise from the outdoor condenser usually points to the fan motor, the fan blade, or debris that has gotten into the cabinet. A hissing or bubbling sound often indicates a refrigerant issue. A loud bang or clunk at startup can be a failing capacitor or a compressor that is struggling to turn over. None of these are sounds to ignore, because a component that is failing under load tends to fail completely when the system is working hardest. Call and describe what you are hearing, and we will tell you what the diagnostic visit covers.
Diagnosis Explained Before Any Repair
When the diagnostic visit identifies a fault, we explain what went wrong and why before any repair is agreed to. You know what the problem is, not just what the fix costs.
Why is one room in my house always hotter or colder than the rest?
Uneven temperatures from room to room usually come from one of three places: the equipment, the ductwork, or the layout of the system. A duct run that has separated or is leaking pushes conditioned air into an attic or wall cavity before it reaches the room. A damper that is stuck or missing means one branch of the duct system gets more airflow than another. If the equipment is operating correctly at the unit but rooms are still uneven, the ductwork is the next place to look. The diagnostic visit covers both sides before any repair is recommended.
What does a thermostat or smart-control upgrade actually involve?
A thermostat replacement starts with confirming that the new control is compatible with the low-voltage wiring on the existing HVAC equipment. Most modern smart thermostats wire to a standard set of terminals, but some systems, particularly heat pumps and multi-stage equipment, need specific wiring configurations. We confirm compatibility on the call before the visit is scheduled. The installation covers removing the old unit, connecting the new control to the existing low-voltage terminals, and verifying that the system responds correctly to the new settings before the visit ends.
How do ductwork leaks raise energy bills, and how is the problem found?
When conditioned air escapes through gaps or separated joints in the duct system, the HVAC equipment has to run longer to bring the house to the set temperature. The air that leaked out did not reach the living space, so the system compensates by running additional cycles. Over a long cooling season in Converse, that extra runtime adds up on the energy bill. Finding the problem starts at the air handler connections and the accessible duct runs, where joints are most likely to separate over time. Sealing those points reduces the loss and brings runtime back down.
Emergency No-Heat and No-Cool Calls Handled
A system that is completely down does not wait for a convenient time. We take emergency heating and cooling calls every day from 7:00 AM to 8:30 PM, and we get the situation scoped on the call.
When does it make sense to choose a heat pump over a furnace for a new installation?
In Bexar County, the mild winters and long cooling seasons make heat pumps a practical fit for many homes. A heat pump moves heat rather than generating it, which works efficiently when outdoor temperatures stay above freezing most of the winter. For homes that already have a gas furnace and ductwork in place, a paired furnace-and-AC setup is often the straightforward replacement path. For homes without existing gas infrastructure, or for additions and spaces that need both heating and cooling without new duct runs, a heat pump or ductless mini-split is worth discussing. The right answer depends on the home, the existing equipment, and how the space is used, and we work through those details on the call.
What are the signs that a compressor or blower motor is starting to fail?
A failing compressor often shows up as an AC that runs but does not cool, a unit that trips the breaker repeatedly, or a loud clunking sound at startup. The compressor is the most expensive component in the outdoor unit, and a system with a failing compressor is often a candidate for replacement rather than repair, depending on the age of the equipment. A failing blower motor shows up as weak airflow from the vents, a system that runs but does not move enough air through the house, or a motor that hums but does not start. Both are identified during the diagnostic visit before a repair path is recommended.
System Checked Before Parts Are Quoted
We start at the equipment and confirm what the system is actually doing before recommending a repair path. That means the quote reflects the real fault, not an assumption.
How long does a full system replacement typically take?
A straightforward residential replacement, swapping out an existing furnace and AC or a heat pump for new equipment of the same configuration, usually takes most of a single day. Work that involves changes to the duct connections, line set, or drain routing takes longer, and that scope is confirmed before the visit is scheduled. Commercial replacements and installations with more complex configurations are scoped individually. You get a clear picture of what the job involves and how long it is expected to take before any work is agreed to.
When should I call a technician rather than trying to fix an HVAC problem myself?
Replacing a filter, clearing visible debris from around the outdoor unit, and resetting a tripped breaker are reasonable first steps a homeowner can take. Anything beyond that, including refrigerant handling, electrical work at the control board or capacitor, heat exchanger inspection, and any work that requires opening the refrigerant circuit, requires proper equipment and knowledge of the system. Attempting refrigerant work without the right tools can damage the compressor and create a safety hazard. If the system is not responding after a basic reset and filter check, the right call is a diagnostic visit.
How does humidity control work differently from standard air conditioning in a Texas climate?
An air conditioner removes moisture as a byproduct of the cooling process, but only while it is running long enough to do so. A system that is oversized for the space short-cycles, reaching the set temperature quickly and shutting off before it has run long enough to pull the humidity down. The result is a house that feels cool on the thermostat but damp and uncomfortable. A whole-home dehumidifier installed in line with the existing HVAC system handles moisture independently of the cooling cycle, running when humidity is high regardless of whether the AC is actively cooling. In a climate like Converse, where summer humidity is persistent, that separation makes a real difference in how the house feels.
