Tiger Air Conditioning is Cedar Hill's call for heating, cooling, and air quality service, whether you own a single-family home, manage a rental property, or run a commercial space in Dallas County. We handle the full range of HVAC work: repairs, installations, seasonal maintenance, and emergency calls around the clock, any day of the week. Same-day HVAC service is available, and we are reachable at any hour, nights, weekends, and holidays included. When your system goes down, you do not have to wait until Monday morning.
We check the furnace. We check the AC. We leave it running right.
This area runs every kind of furnace, AC, and heat pump, and we work on all of it. Whether you are dealing with a system that stopped overnight or one that has been limping along for months, here is what we handle on a daily basis.
When the AC stops cooling or starts blowing warm air, the cause could be a refrigerant leak, a failing compressor, a clogged evaporator coil, or a condenser issue. We diagnose it properly before recommending a repair, and we carry the parts to handle most central air repairs in a single visit. We'll find the fault and set it right.
Furnace problems show up fast, especially during a Texas cold snap. If your furnace is blowing cold air, cycling on and off, or not responding at all, we trace the fault to the source. Ignition issues, heat exchanger problems, and airflow failures are all work we handle on Cedar Hill heating calls every season.
Heat pumps and ductless mini-split systems need their own approach. If yours is not heating in winter or not cooling in summer, the issue is often refrigerant, a reversing valve, or a sensor fault. We service all major heat pump brands and handle ductless mini-split repairs for additions, garages, and spaces that do not connect to the main duct system.
A thermostat that is not reading correctly or not communicating with your equipment can make the whole system behave erratically. We install replacement thermostats and smart controls, including programmable and Wi-Fi models that give you better control over your comfort and energy use.
Leaky ductwork is one of the more common reasons a home has uneven temperatures or high utility bills. We inspect, repair, and seal ductwork so conditioned air reaches every room the way it should.
Indoor air quality is part of the job too. If your home feels stuffy, dusty, or your family is dealing with allergy-related issues, we install whole-house air filtration systems and air purifiers that work with your existing HVAC equipment. Estimates are explained up front with no pressure, so you know what the work covers before anything is scheduled.
North Texas does not give HVAC equipment an easy life. Cedar Hill summers run long and hot with sustained humidity, and winters bring brief but sharp cold snaps that can catch an aging system off guard. The equipment here has to perform at both ends of the range, and that kind of demand shortens the life of systems that are not properly maintained or sized. The three services below come up constantly in this area, and for good reason.
When a system has been repaired multiple times, is losing efficiency, or simply cannot keep up with a Texas summer anymore, replacement is often the smarter call. A full HVAC system replacement means pulling the old equipment and installing a matched furnace and central AC unit sized correctly for the home. In Cedar Hill, where systems work hard through months of heat and then pivot to handle winter cold, equipment wears faster than in more moderate climates. We assess the existing setup, recommend the right replacement equipment, and handle the full installation from start to finish.
Heat pumps are a strong fit for the North Texas climate. Mild winters mean the system runs efficiently in heating mode, and modern heat pumps deliver serious cooling capacity through the summer months. Installation covers equipment selection, proper sizing for the space, and full equipment connection on the HVAC side. For areas of a home or property without existing ductwork, ductless mini-split heat pumps are a practical option that avoids the cost and disruption of adding new ducts.
Dallas County summers bring humidity that makes indoor air feel significantly warmer than the thermostat reads, and that extra moisture puts added strain on your AC system as it tries to compensate. A whole-home dehumidifier works alongside your existing HVAC equipment to pull moisture out of the air at the source, rather than relying on a portable unit in one room. The result is air that feels more comfortable at a higher set point, which also takes load off the cooling system. This is an indoor air quality improvement as much as a comfort one, and it matters throughout the year in this part of Texas.
When the heat or the AC quits, the situation does not wait for a convenient time. A system down in July in Cedar Hill is not a minor inconvenience, and a furnace that stops working during a cold snap needs attention immediately. We take emergency calls at any hour, every day, including weekends and holidays. There is no "after hours" here because there are no closed hours.
Property managers and landlords know this problem well. A tenant without heat or cooling is a liability, and getting a qualified HVAC technician on site fast matters. We handle apartment HVAC repairs, rental property heating and cooling calls, and commercial emergency service across Cedar Hill and the surrounding area. Same-day HVAC service is available for urgent calls, and we prioritize no-heat and no-cool situations accordingly.
When you call, you reach someone who knows the trade and can scope the job before anything is scheduled.
One call. One technician. One fair price.
Whether this is your first HVAC repair or your tenth, the process is the same: we show up, diagnose the issue properly, and explain what the fix involves before any work begins. For homeowners, that means seasonal tune-ups, HVAC inspections, diagnostic calls, and system repairs handled by qualified HVAC technicians who know what they are looking at. A spring AC tune-up before the heat sets in and a fall furnace check before the first cold snap are the two maintenance calls that prevent most emergency situations.
For commercial customers, offices, multi-unit properties, and property managers, we handle commercial AC repair, commercial heating repair, and full commercial HVAC installation and replacement. The stakes are higher when multiple tenants or employees are affected, and we approach commercial calls with the same urgency as residential emergencies. Every job ends with the system tested and readings checked before sign-off, whether it is a residential tune-up or a commercial system replacement. We'll get your home comfortable again fast.
HVAC pricing depends on the job: a diagnostic call, a repair, a seasonal tune-up, and a full system replacement each involve different scopes. The way to get the right number is to call. We go over what the visit covers, what the diagnostic includes, and what any recommended repair or installation will cost before anything is put on the schedule. Pricing is straightforward and explained clearly, so you know what you are agreeing to before the work starts.
If you have questions about what a diagnostic fee covers or what a replacement estimate includes, ask on the call. You get a straight answer. We'll diagnose it, fix it, and test it before we leave.
Cedar Hill is our primary service area, and we cover the surrounding communities across Dallas County and beyond. If you are in one of the following areas, we can get to you:
Whether you are calling from Cedar Hill itself or from a neighboring city, the same service applies. Call and we will confirm coverage at your address.
An AC that runs without cooling is one of the more common summer calls we get in Cedar Hill. The most frequent causes are a refrigerant leak, a dirty or frozen evaporator coil, or a failing condenser. A proper diagnosis tells us which one is driving the problem, and in most cases we can complete the repair in the same visit once the fault is confirmed.
Unusual sounds from an HVAC unit almost always point to a mechanical issue that will get worse if the system keeps running. Banging often means a loose or broken component inside the blower or compressor. Squealing usually points to a belt or motor bearing issue, and rattling can indicate debris in the system or loose panel hardware. Call us and describe the sound so we can give you a sense of what is likely going on before the technician arrives.
Uneven temperatures room to room are usually a ductwork issue, a sizing problem, or both. Leaking ducts lose conditioned air before it reaches the room, and a duct that is undersized for the space it serves will never deliver enough airflow to balance the temperature. We inspect the duct system, check airflow at the registers, and identify where the imbalance is coming from before recommending a fix.
The decision comes down to the age of the equipment, the cost of the repair relative to the value of the system, and whether the system can realistically keep up with demand after the repair is done. An older system that has already been repaired multiple times and is losing efficiency is often better served by a replacement that brings reliability and performance back in line with what the home needs. We walk through both options clearly so you can make the call with good information.
Additional charges come from parts and labor for repairs beyond the initial diagnostic scope. If the technician finds a fault that requires a component replacement or additional work, the cost is explained and confirmed before anything is done. There are no charges added to the job without your knowledge and agreement first.
Same-day HVAC service is available, and we prioritize calls where the system is completely down. Because we are open at any hour, any day of the week, same-day scheduling applies around the clock, including nights, weekends, and holidays. Call (945) 356-6987 and describe the situation, and we will work to get a technician out as quickly as possible.
An aging system works harder to deliver the same amount of heating or cooling, which means longer run times and higher energy consumption. Worn compressors, low refrigerant, dirty coils, and leaking ducts all force the system to compensate, and that compensation shows up on the utility bill. A tune-up or targeted repair often brings efficiency back, but if the system is near the end of its useful life, a replacement is usually the more cost-effective path.
Leaky ducts lose conditioned air into unconditioned spaces like attics and wall cavities before it ever reaches the living area. Undersized ducts restrict airflow and force the system to run longer to reach the set temperature. Both problems raise energy costs and create the uneven temperatures that make certain rooms uncomfortable. Duct sealing and repair address the problem at the source rather than compensating for it with a bigger or newer unit.
Some basic steps are safe to try on your own, like checking that the thermostat is set correctly, replacing a dirty filter, or confirming the circuit breaker for the unit has not tripped. Beyond that, HVAC systems involve refrigerant, high-voltage components, and gas connections that require proper training and equipment to handle safely. Attempting a repair without that background can make the problem worse or create a safety hazard, so calling a qualified HVAC technician is the right move for anything beyond the basics.
For most diagnostic and repair work, the technician will shut off power to the equipment at the unit before working on internal components. This is standard procedure for safe HVAC service. The technician handles this as part of the visit, so you do not need to do anything in advance unless we ask you to when you call.
Older homes in Cedar Hill often have ductwork that was sized for smaller or less efficient equipment, which creates airflow imbalances and uneven temperatures throughout the house. Aging equipment loses efficiency over time and may struggle to keep up during peak summer heat or a sharp winter cold snap. In some cases, the system has been repaired enough times that a full replacement is the more practical path to reliable comfort.
Smart thermostat installation starts with checking that the existing wiring at the thermostat location is compatible with the new unit. Most modern smart thermostats work with standard HVAC wiring, though some older systems may need a small adapter to provide the common wire the thermostat needs to operate. We handle the installation and configuration so the thermostat is communicating correctly with the HVAC equipment before we leave.
Heat pump installation covers equipment selection, proper sizing for the space, and the full HVAC-side connection, including refrigerant line sets, electrical connections at the unit, and integration with the existing duct system or, for ductless mini-splits, the indoor air handler. North Texas winters are mild enough that a heat pump handles the heating season efficiently, and the same system delivers serious cooling capacity through the summer months. We confirm the system is running correctly and readings are checked before the job is signed off.
Dallas County summers bring sustained humidity that makes indoor air feel significantly warmer than the thermostat reads, and that extra moisture puts added strain on the AC system as it tries to compensate. A whole-home dehumidifier works alongside the existing HVAC equipment to pull moisture from the air across the entire house, rather than relying on a portable unit in one room. The result is more consistent comfort and less load on the cooling system through the long Texas summer.
For heating repair, AC repair, heat pump installation, system replacement, or an emergency call at any hour, we are ready to help. Tiger Air Conditioning covers Cedar Hill and the surrounding Dallas County area with the full range of residential and commercial HVAC service.
We check the furnace. We check the AC. We leave it running right.

How often should I schedule a tune-up or maintenance visit for my HVAC system?
Most HVAC equipment benefits from two maintenance visits per year, one in spring before the cooling season and one in fall before the heating season. In Cedar Hill, where systems work hard through long hot summers and then pivot to handle winter cold snaps, staying on that schedule helps catch worn components, refrigerant issues, and airflow problems before they turn into a no-heat or no-cool situation. We inspect, clean, and test the equipment on each visit and check readings before we leave.
What are the signs that my AC or furnace may need to be replaced rather than repaired?
Age, repair history, and performance are the three things we look at. A system that is well past its typical service life, has been repaired multiple times in recent seasons, or simply cannot keep up with a Texas summer or a winter cold snap is often better served by a replacement. If the cost of a repair approaches a significant portion of what a new system would cost, replacement usually makes more financial sense. We walk through both options clearly so you can decide with good information.
What does a seasonal tune-up actually cover?
A tune-up is a thorough inspection and cleaning of the HVAC equipment, not just a filter swap. We check refrigerant levels and pressures, inspect the heat exchanger or evaporator coil, test safety controls, clean components that accumulate dust or debris, and verify that the system is starting, running, and shutting down correctly. The system is tested and readings are checked before we sign off. The goal is to find anything that is wearing or out of spec before it causes a breakdown.
Same-Day and Emergency Availability
We take calls at any hour, every day of the week, including nights, weekends, and holidays. When the system is completely down, we prioritize getting a qualified HVAC technician out as quickly as possible.
What are common signs of a refrigerant or airflow problem?
A refrigerant issue often shows up as an AC that runs continuously but cannot bring the temperature down, ice forming on the evaporator coil, or a hissing or bubbling sound near the indoor unit. Airflow problems tend to produce weak output at the registers, uneven temperatures from room to room, or a system that short-cycles because it cannot move enough air to satisfy the thermostat. Both problems get worse the longer they run, so calling us early limits the damage.
How do I choose between a furnace and a heat pump for my Cedar Hill home?
The North Texas climate makes heat pumps a practical choice for most homes here. Mild winters mean a heat pump operates efficiently in heating mode without the efficiency drop that colder climates can cause, and the same system handles summer cooling. A gas furnace paired with a central AC unit is still a solid option, particularly in homes that already have gas service and existing ductwork sized for that setup. We assess what you have, what the space needs, and what makes the most sense for your situation before recommending equipment.
Do I need to be home while the HVAC work is being done?
For most HVAC repairs and installations, someone needs to be present to provide access to the equipment and to review the findings and pricing before work begins. If you have a situation where being home is difficult, call us and we can talk through the specifics. For some diagnostic calls, arrangements can sometimes be made, but the general expectation is that an adult is available at the property during the visit.
Diagnosis Explained Before Any Repair
We tell you what we found and what the fix involves before any work begins. You get a clear picture of the problem and the cost before anything is added to the job.
How does pricing work for an HVAC repair or installation call?
Pricing depends on the scope of the job. A diagnostic call, a repair, a tune-up, and a full system replacement each involve different work and different costs. The right way to get an accurate number is to call. We go over what the visit covers, what the diagnostic includes, and what any repair or installation will cost before anything is scheduled. Pricing is explained clearly up front, and no work is added to the job without your knowledge and agreement.
What causes a system to short-cycle, and is it a serious problem?
Short-cycling means the system starts, runs briefly, shuts off, and then starts again before completing a normal heating or cooling cycle. It is a sign that something is wrong, and it puts extra wear on the compressor and other components each time it happens. Common causes include a dirty filter restricting airflow, a refrigerant charge that is off, a thermostat reading incorrectly, or an oversized system that cools or heats the space too quickly. We diagnose the root cause rather than treating the symptom, because short-cycling that continues will shorten the life of the equipment.
Experienced With Older and Newer Systems
Cedar Hill homes run a wide range of equipment, from older gas furnaces to modern heat pump systems. We work on all of it and bring the same thorough approach regardless of the equipment age or brand.
Is older HVAC equipment worth repairing, or is replacement the smarter move?
It depends on what is wrong and how the rest of the system is holding up. A relatively inexpensive repair on a system that is otherwise in good shape can add useful years of service. A major component failure on aging equipment, like a compressor or heat exchanger, is a different calculation. At that point, the cost of the repair, the age of the system, and its overall efficiency all factor into whether repair or replacement makes more sense. We give you both options with honest numbers so you can make the call.
How does a dirty filter or coil affect HVAC performance?
A clogged filter restricts airflow through the system, which forces the blower to work harder and reduces the amount of conditioned air reaching the living space. Over time, restricted airflow causes the evaporator coil to freeze, which stops cooling entirely. A dirty coil, whether from a failed filter or just accumulated buildup, insulates the refrigerant from the air it is supposed to condition and drops efficiency significantly. Replacing the filter regularly and having the coil inspected during a tune-up prevents both problems.
How long does a full HVAC system replacement typically take?
Most residential system replacements are completed in a single day. The timeline depends on the equipment being installed, the condition of the existing ductwork and connections, and whether any additional work is needed to bring the installation up to current standards. We confirm the scope and the expected timeline before the job starts so you know what to plan for. The system is tested and performance is verified before we consider the job complete.
