Olive Branch HVAC Company handles heating and cooling for homes and businesses across Olive Branch and the wider DeSoto County area. Whether the furnace quit on a cold January morning or the AC stopped keeping up with a Mississippi summer, we scope the job on the phone, confirm pricing before anything is scheduled, and send someone who knows the work.
Reach us at (662) 879-5465, seven days a week from 7:30 AM to 8:30 PM. Residential HVAC. Commercial HVAC. One number for both.
Calling an HVAC company doesn't have to be stressful, and it doesn't have to start with a guessing game on price. When you call, we talk through what's happening with the system, get a clear picture of the job, and give you the rate before anything gets put on the calendar. That goes for a homeowner dealing with a broken AC, a landlord managing a rental with a heating problem, and a property manager keeping a commercial space comfortable through the summer.
We cover the full range: AC repair and service, furnace repair, heat pump work, full system replacement, seasonal maintenance, ductwork, thermostats, and indoor air quality. Call and we'll handle the furnace, the AC, and the ductwork.
Most HVAC calls fall into a handful of categories: something stopped working, something isn't working right, or a system needs a check before the season turns. Here's what each of those visits actually involves.
When an air conditioner stops working or starts blowing warm air, the cause is usually somewhere in the refrigerant circuit, the condenser, or the evaporator coil. The visit starts with a full system check: refrigerant pressure, condenser and compressor function, and an evaporator coil inspection for ice buildup or fouling. A system that's short on refrigerant almost always has a leak, and we find it before quoting any parts. Central AC repair, whether it's a refrigerant issue or a failed component, gets diagnosed before any repair is proposed.
Before a small issue turns into a full breakdown, a furnace will usually give you a signal: cold air from the vents, short cycling, or a unit that runs but can't hold temperature. The visit covers the heat exchanger, blower motor and airflow, and thermostat signal verification to find where the system is losing performance. We take pride in the HVAC work we leave behind, which means the diagnosis is explained clearly and the repair is scoped before any work is authorized. Emergency heating repair is available within our posted hours if the system goes down hard.
Heat pumps handle both heating and cooling, which makes a malfunction a year-round problem in DeSoto County's mixed climate. A system stuck in one mode, one that's lost efficiency, or one that simply won't run gets a full diagnostic covering refrigerant charge, reversing valve operation, and airflow through the air handler. Heat pump repair and service covers both sides of the system, because a problem in heating mode often points to the same component that affects cooling performance.
A thermostat that isn't reading correctly, cycling at the wrong time, or simply failing to communicate with the equipment can make a perfectly functional HVAC system behave like a broken one. Thermostat installation and smart thermostat replacement involves wiring verification, compatibility checks against the existing equipment, and calibration after the install. We'll explain the diagnosis before any work is authorized, so you know exactly what's being changed and why.
Rooms that won't cool down, uneven temperatures from one end of the house to the other, and a system that runs constantly without hitting the set point are all common signs of leaking ductwork. Older housing stock in DeSoto County often has duct connections that have loosened over time or were never sealed well to begin with. Duct sealing and ductwork repair address those losses directly, and most rooms feel the difference as soon as the system cycles through after the work is done.
Whole-home air filtration works alongside the existing HVAC equipment to pull dust, allergens, and particulates out of the air before they circulate through the house. The job involves sizing the filter system to the equipment and the square footage, then integrating it with what's already installed. Call and we'll get the air running right.
DeSoto County sits in a humid subtropical zone. Summers are long and intensely hot, winters are short but can arrive hard, and humidity is a factor in every season. The services below come up regularly here for reasons specific to this climate.
An aging system that struggles through a long Olive Branch summer and then gets pushed hard again in January is one that's likely to fail at the worst time. Full HVAC system replacement starts with a load calculation to size the equipment correctly for the home, then moves to removing the old unit, installing the new system, and commissioning it with airflow and refrigerant verification before the job is signed off. Careful HVAC work that respects your home means the installation site is left clean and the system is tested before we leave. A second opinion on a replacement quote is a fair thing to ask for.
DeSoto County's winters are mild enough that a heat pump handles heating efficiently for most of the season, while the same equipment carries the full cooling load through the summer. Heat pump installation covers site assessment, equipment selection, installation, refrigerant charge verification, and airflow testing. For additions, garages, or spaces without existing ductwork, mini-split and ductless options are available and get the same installation process. We'll find the fault and set it right on any heat pump job, whether it's a new install or a replacement of an older unit.
Humidity in this part of Mississippi doesn't go away when summer ends. Excess moisture in the home affects comfort, contributes to air quality problems, and puts stress on building materials year-round. A whole-home dehumidifier integrates directly with the existing HVAC equipment and is sized to the home's square footage and typical moisture load. Humidity-level calibration is part of the install, and readings shared at the end of a maintenance visit give you a clear picture of how the system is performing.
Getting your comfort problem handled starts with a quick call, but the best time to catch a problem is before it becomes one. A seasonal HVAC tune-up covers filter condition, coil cleaning, refrigerant level check, electrical connection inspection on the unit, thermostat calibration, and airflow readings. Pre-season service on the AC before summer or the furnace before winter is the most reliable way to avoid an emergency call when the system is working hardest. We find it. We fix it. We test the airflow.
Choosing the right HVAC fix is easier than it sounds when you have someone on the phone who can talk through the symptoms and scope the job before anything is scheduled.
When the heat goes out or the AC stops in the middle of a Mississippi summer, call (662) 879-5465.
We're available every day from 7:30 AM to 8:30 PM for short-notice and emergency calls, including no-heat and no-cool situations. The job is scoped on the call, the price is confirmed before we schedule, and the diagnostic covers the full system before any parts are quoted.
Homeowners, landlords, property managers, and business owners all call for different reasons, but the process is the same: the job is understood before anyone is scheduled. For a homeowner it might be a furnace repair or a system replacement. For a landlord managing a rental property, it's a quick diagnosis and a price confirmed on the call so the tenant isn't waiting. For a property manager overseeing office or retail space, it's commercial HVAC service that gets the building back to a comfortable temperature without a drawn-out back-and-forth.
We handle light commercial HVAC work across DeSoto County: offices, retail spaces, and multi-unit properties. The same approach applies whether the call comes from a homeowner or a facilities contact.
Before a small issue turns into a full breakdown, it's worth knowing what a service call actually involves. When you call, we ask about the system, the symptoms, and the property. From there the job gets scoped on the phone and the service call cost is explained before anything is put on the schedule. There's no commitment required to get that information. If the visit leads to a repair, the diagnostic findings are explained and the repair cost is confirmed before any work is authorized. Local service. Reliable systems. Costs set out on the call.
We serve Olive Branch and the communities around it across DeSoto County and into the greater Memphis metro. If you're nearby, we cover your area.
Common signs include the furnace cycling on and off before the house reaches temperature, cold air coming from the vents during a heating cycle, and rooms that stay cold even when the system is running. Unusual sounds from the blower or a burning smell when the heat first comes on are also worth paying attention to. A diagnostic visit covers the heat exchanger, ignition system, and blower motor to find where the system is losing performance.
An AC that runs constantly but can't hold the set temperature, one that starts blowing warm air, or one that short-cycles and shuts off before the house cools are all signs something is wrong. Unusual sounds from the condenser or ice forming on the refrigerant lines are also common indicators. The diagnostic covers refrigerant pressure, coil condition, and compressor function before any repair is proposed.
A frozen evaporator coil blocks airflow through the system, which means the air conditioner runs but very little conditioned air reaches the living space. Weak airflow from the vents, ice visible on the refrigerant lines near the air handler, or water pooling near the indoor unit are all signs of this problem. The fix usually involves letting the coil thaw, finding the cause of the freeze, and addressing the underlying refrigerant or airflow issue.
The outdoor unit inspection covers refrigerant pressure, condenser coil condition, compressor operation, and the electrical components on the unit including the capacitor and contactor. For a heat pump, the reversing valve and defrost cycle are also checked. The condition of the outdoor coil matters too, because a fouled coil reduces heat transfer and makes the whole system work harder.
Uneven temperatures across a home usually point to ductwork losses, a sizing mismatch between the equipment and the space, or an airflow imbalance in the distribution system. Leaky ducts pull conditioned air into unconditioned spaces before it reaches the room it was meant for, and the system runs longer trying to compensate. A duct inspection identifies where the losses are happening, and sealing or replacing the affected runs typically brings the airflow back into balance.
A burning smell when the heat first comes on at the start of the season is often dust burning off the heat exchanger and is usually harmless, but a persistent burning smell during normal operation can indicate a motor or electrical component issue on the equipment. A musty smell from the vents typically points to moisture in the ductwork or on the evaporator coil, which can develop into a mold or mildew problem if it is not addressed. Either situation is worth a diagnostic visit to find the source before it gets worse.
If the heat is out, keep interior doors closed to retain warmth in the rooms you are using, and avoid running space heaters unattended. If the AC is down during a Mississippi heat wave, close blinds on sun-facing windows and move to the coolest part of the house. Do not attempt to reset the system repeatedly if it is tripping a safety switch, as that can point to a condition that needs a proper diagnosis rather than a restart.
A heat pump moves heat rather than generating it. In cooling mode it pulls heat out of the indoor air and releases it outside, the same way a central air conditioner works. In heating mode the process reverses, and the system pulls heat from the outdoor air and moves it inside. In DeSoto County's climate, a heat pump handles most of the heating load efficiently through a Mississippi winter, and the same equipment carries the full cooling load through the summer.
A repair makes sense when the system is relatively young, the failed component is straightforward, and the repair cost is a small fraction of what a replacement would run. When a system has needed multiple repairs in a single season, is old enough that efficiency has dropped significantly, or when the repair cost approaches a meaningful share of replacement cost, the math shifts toward replacement. We walk through both options and give you the information you need to make that decision for your specific situation.
Adding refrigerant without finding the leak, replacing a failed capacitor without checking why it failed, or sealing ductwork without inspecting the full run are all examples of fixes that address the symptom rather than the cause. The problem returns, often faster than the first time, and the cost of the second call is added to the first. The diagnostic is where the repair starts, and skipping it saves time on the visit while setting up the next one.
The diagnostic starts with what the system is doing and works back to the cause. Refrigerant pressure readings, airflow measurements, electrical component checks, and a visual inspection of the heat exchanger or coil give a clear picture of where the system is losing performance. The repair is scoped from those findings, and the cost is explained before any work is authorized.
After a repair or installation, the system is run through a full cycle to confirm the fix is working as expected. For a cooling job that means checking supply air temperature, verifying the refrigerant charge is within spec, and confirming airflow at the registers. For a heating job it means verifying ignition, heat exchanger airflow, and blower motor operation under load. The visit does not end with the system untested.
When both the thermostat and the ductwork are part of the problem, the diagnostic covers both before any repair is proposed. A thermostat that is not reading accurately can mask how much of the issue is actually duct-related, so the two need to be evaluated together. We explain what each component is contributing to the problem and what addressing each one would involve before any work is authorized.
A system that is losing refrigerant charge, has a fouled coil, or is working against leaky ductwork runs longer to hit the same temperature, and that extra runtime shows up on the utility bill. A compressor that is struggling to maintain pressure draws more power than a healthy one. A tune-up that catches those conditions early is usually a smaller cost than the extra energy the failing system is already consuming.

We're available every day from 7:30 AM to 8:30 PM. Residential HVAC. Commercial HVAC. One number for both.
Every heating and cooling job we handle in Olive Branch starts the same way: a conversation on the phone, a clear scope of the work, and a price confirmed before anything is scheduled. The table below lays out what each service covers, who it fits best, and a practical note to help you decide what to ask for when you call. Whether the need is a quick repair or a full system replacement, the process is the same from the first call to the final test.
| System Service | What's Included | Best For | Things to Know |
|---|---|---|---|
| Full System Installation & Replacement |
| Homeowners whose system has aged past the point where repair is the better value | Correct sizing matters more than brand selection. An oversized or undersized system creates comfort and efficiency problems from day one. |
| Indoor Air Quality & Air Filtration |
| Households where dust, allergens, or air quality are a consistent concern | Whole-home filtration works with the existing equipment rather than replacing it. Sizing it correctly to the system matters for both air quality and equipment performance. |
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want to catch problems before the system is working hardest in peak season | Pre-season service on the AC before a Mississippi summer, or the furnace before winter, is the most reliable way to avoid an emergency call at the worst time. |
| Heating & Furnace Repair |
| Any home or rental where the heat is running but not holding temperature, or not running at all | Short cycling and cold air from the vents are early signals. Catching them before a full breakdown usually means a smaller repair. |
| Thermostat Installation & Smart Controls |
| Homeowners whose thermostat is misreading, cycling incorrectly, or failing to communicate with the equipment | A faulty thermostat can make a fully functional HVAC system behave like a broken one. The diagnostic confirms which is the cause before anything is replaced. |
| Emergency HVAC Service |
| Any home or property where the heating or cooling system has gone down and comfort or safety is at stake | We are available every day from 7:30 AM to 8:30 PM for emergency calls. The job is scoped on the phone before anyone is dispatched. |
| Ductwork Repair & Sealing |
| Homes with uneven temperatures, rooms that won't cool, or a system that runs constantly without hitting the set point | Older housing stock in DeSoto County often has duct connections that loosened over time. The airflow improvement from sealing is usually noticeable within a short time after the work is complete. |
| AC Repair & Service |
| Homeowners or tenants with a system blowing warm air or not cooling to temperature | A system short on refrigerant almost always has a leak. We find it before quoting any parts. |
| Whole-Home Dehumidification & Humidity Control |
| Olive Branch homeowners dealing with persistent indoor humidity issues outside of summer | Humidity in this part of Mississippi is a year-round factor, not just a summer one. A whole-home unit addresses moisture load in every season. |
| Heat Pump Repair & Service |
| DeSoto County homes where the heat pump handles both heating and cooling year-round | A problem in heating mode often points to the same component that affects cooling. Both sides get checked in the same visit. |
| Heat Pump Installation |
| DeSoto County homes where mild winters make a heat pump an efficient choice for both seasons | The same equipment that handles the full Mississippi summer cooling load also covers most of the winter heating load efficiently. |
How often should HVAC maintenance be scheduled?
Most systems benefit from a tune-up twice a year: once before the cooling season starts and once before the heating season. In a climate like Olive Branch's, where the AC runs hard through a long summer and the furnace or heat pump picks up in winter, pre-season service catches worn components and airflow problems before they turn into emergency calls. A single annual visit is better than none, but two gives the system a check at each seasonal transition.
What causes a system to short-cycle?
Short-cycling, where the system turns on and off before the space reaches the set temperature, usually points to one of a few causes: an oversized system that cools or heats the area near the thermostat too quickly, a refrigerant charge problem, a dirty coil restricting airflow, or a thermostat that is not reading the space accurately. The diagnostic covers all of those possibilities before a repair is proposed, because the fix depends on which one is actually driving the behavior.
What do strange noises from the HVAC unit usually mean?
A rattling sound often points to a loose panel or debris in the blower housing. A grinding or squealing noise from the air handler typically indicates a blower motor bearing that is wearing out. A clicking sound that continues after startup can point to a failing relay or capacitor on the outdoor unit. Banging from the furnace at startup or shutdown is sometimes a duct expansion issue and sometimes a delayed ignition problem. Any noise that is new or getting worse is worth a diagnostic visit before it leads to a component failure.
System Checked Before Parts Are Quoted
We run a full diagnostic before any repair is proposed. Refrigerant pressure, airflow, and electrical components all get checked so the repair addresses the actual cause, not just the symptom.
How does a dirty filter or coil hurt system performance?
A clogged filter restricts the airflow the system needs to move conditioned air through the home, which makes the equipment run longer to hit the same temperature and puts extra strain on the blower motor. A fouled evaporator coil reduces the surface area available for heat transfer, which means the refrigerant circuit has to work harder for the same output. Either condition shows up as higher energy use, longer run times, and eventually as a comfort problem or a component failure. Coil cleaning and filter replacement are part of every tune-up we perform.
Do I need to be home when the HVAC work is done?
For most service calls and repairs, yes. The person doing the work needs access to the equipment, and the diagnostic findings and repair scope are explained directly to the homeowner or property contact before any work is authorized. For rental properties, a landlord or property manager can arrange access through a tenant, but someone with authority to approve the work needs to be reachable by phone during the visit so the scope and price can be confirmed before anything starts.
When is older equipment worth repairing rather than replacing?
The general guide is this: if the repair cost is a small fraction of what a replacement would run and the system is not yet approaching the end of its typical service life, a repair usually makes sense. When a system has needed multiple repairs in the same season, when efficiency has dropped enough that energy bills reflect it, or when the repair cost approaches a meaningful share of replacement cost, the math shifts toward replacement. We walk through both options and give you the information you need for your specific equipment and situation.
Diagnosis Explained Before Any Repair
The findings from the diagnostic are explained clearly before any work is authorized. You know what the system is doing, why it is doing it, and what the repair involves before anyone picks up a tool.
How do ductwork leaks affect energy bills?
Leaky ducts pull conditioned air into unconditioned spaces like attics, crawl spaces, or wall cavities before it reaches the rooms it was meant for. The system compensates by running longer, and that extra runtime shows up on the utility bill. In a home where a significant share of the duct run is losing air, the energy penalty can be substantial. Sealing those losses brings the airflow back into balance and typically reduces how long the system has to run to hit the set temperature.
What is involved in a smart thermostat upgrade?
A smart thermostat installation starts with a wiring check to confirm the existing low-voltage control wiring is compatible with the new unit. Some older systems or heat pumps require a common wire that was not part of the original install, and that gets addressed before the new thermostat goes in. After installation, the thermostat is calibrated against the equipment and tested through a full cycle to confirm it is communicating correctly with the heating and cooling system. We walk through the settings and scheduling features before we leave.
Emergency No-Heat and No-Cool Calls Handled
We take short-notice and emergency calls every day from 7:30 AM to 8:30 PM. The job is scoped on the phone and the price is confirmed before we schedule, even on an urgent call.
What are the signs of a failing compressor?
A compressor that is starting to fail often shows up as an AC that runs but cannot lower the indoor temperature, even on a mild day. Hard starting, where the outdoor unit struggles to turn on or trips a safety switch, is another common sign. A system that is drawing noticeably more power than usual, or one where the refrigerant pressure readings are outside the normal operating range, can also point to compressor wear. The diagnostic covers compressor operation along with the rest of the refrigerant circuit before any parts are quoted.
How does whole-home dehumidification work alongside the existing HVAC system?
A whole-home dehumidifier integrates directly with the existing air handler and ductwork, pulling return air through the dehumidifier before it circulates back through the home. It operates independently of the cooling cycle, which means it can reduce humidity even when the AC does not need to run for temperature. In a climate like DeSoto County's, where humidity stays elevated well into the fall and can be a factor in winter too, that independence from the cooling cycle is what makes a whole-home unit more effective than a portable one.
How long does a full system replacement typically take?
Most residential system replacements are completed in a single day. The timeline depends on the equipment being replaced, whether the ductwork and electrical connections are in good condition, and whether the new equipment requires any modifications to the existing installation. A load calculation is done before the job is scheduled to confirm the right equipment size, so the install day is not spent working out details that should have been settled on the call. We confirm the scope and the timeline before anything is put on the schedule.
