Call with a description of what the system is doing, answer a few questions about the equipment and the property, and we take it from there. Tiger Air Conditioning covers Mesquite and the surrounding Dallas County area with the full range of residential and commercial heating-and-cooling work: AC repair, furnace repair, heat pump service, full system replacement, ductwork, and more. Same-day HVAC service is available, and we are reachable at any hour, any day of the week, including nights, weekends, and holidays.
Mesquite is a large city with a wide mix of housing stock and commercial properties, and the calls we get here reflect that variety. Apartment managers dealing with a tenant who has no cooling, property owners weighing a repair against a full replacement on aging equipment, and business operators who cannot afford to shut down while a rooftop unit gets sorted are all situations we handle regularly. The process is the same for all of them: describe the problem, get a price, and we schedule from there.
An old thermostat does one thing: it reads the temperature at the wall and tells the system to run until it hits a number. A modern programmable or smart control does considerably more. It adjusts run schedules based on occupancy, communicates with the equipment directly to catch performance issues early, and lets you set different conditions for different times of day without touching a dial.
Replacing a thermostat on its own is often worth doing even when the rest of the system is running fine. If the control is misreading the temperature, cycling the equipment on and off too frequently, or simply not responding reliably, the rest of the system pays for it in wear and energy use. We install and configure thermostats and smart-control systems for both residential and commercial properties, and we set them up correctly for the equipment they are connected to before we leave.
Whether this is your first HVAC repair or your tenth, a system that stops working entirely is a different situation from one that is running poorly. We treat no-heat and no-cool calls as urgent, and same-day service is available for both. There is no after-hours distinction here because there are no closed hours. Call at any point in the day or night, on a weekend or a holiday, and someone picks up.
Properties in Mesquite often have people in them who cannot simply leave while the work is done. Tenants, employees, and customers all factor into how a job gets arranged. When you call, let us know what the situation is on the property and we will work through the scheduling accordingly. The goal is to get the system running again with as little disruption as possible.
The technician diagnoses the fault before recommending any repair. That means checking the equipment properly rather than guessing at a cause. Once the fault is identified, the scope and cost of the fix are explained before any work begins. The system is tested and readings checked before sign-off, so you know it is working correctly before we leave. We'll diagnose it, fix it, and test it before we leave.
Rooftop HVAC units serve a lot of the commercial space in a city this size, from retail strips to light industrial. When a rooftop unit fails, it affects the whole floor below it, and a business that has to stay open needs a fast diagnosis and a clear answer about what the repair involves. We handle rooftop unit repair and replacement, and we work through the diagnostic the same way we would on any residential call: find the fault, explain the fix, confirm the price before anything is done.
When a system has been repaired enough times that the math stops making sense, or when it simply cannot keep up with demand anymore, a full replacement is the right answer. We handle complete HVAC system replacement for homes and commercial properties throughout Mesquite, including central air and furnace pairings, heat pump systems, and ductless mini-split setups for spaces without existing ductwork. Equipment is selected and sized for the property, not chosen off a shelf and dropped in.
An AC that does not respond when the thermostat calls for cooling could be a failed capacitor, a tripped safety switch, a refrigerant pressure fault, or a compressor issue. The cause matters, because the repair and the cost differ significantly between them. We run a proper diagnostic before drawing any conclusion, and we explain what we found and what it costs to address before touching anything.
A furnace that stops producing heat is one of the more common calls we get during cold stretches in the region. Ignition failures, limit switch faults, pressure switch problems, and heat exchanger issues all present differently, and the right repair depends on which one is actually driving the problem. We carry parts for the most common furnace repairs and complete most of them in a single visit. We'll find the fault and set it right.
When a home or commercial space adds square footage, the existing duct system rarely extends to it cleanly. A room addition that shares a duct run with the rest of the house often ends up too warm in summer and too cold in winter because the airflow was never balanced for the new layout. We design and install ductwork for additions, making sure the new space connects to the system properly rather than just borrowing from whatever duct happens to be nearby.
Your time matters, so we keep the HVAC job moving from the first call through the final test. Pricing on an HVAC call depends on what the job actually turns out to involve. A straightforward repair on accessible equipment is a different scope from a fault buried in a difficult location, or a situation where the diagnosis reveals that replacement makes more sense than repair. We do not invent a number before we know what we are dealing with.
When you call, we go over what the system is doing and give you a price based on that description. The price is confirmed on site once the technician has diagnosed the fault, and any change to the scope is explained before additional work is authorized. No-pressure estimates, priced up front, so you know what the visit covers before you commit.
If the question is whether to repair or replace, we walk through both options with the numbers attached so you can make the call with clear information. The service page carries the full breakdown of what each type of job covers.
Most homeowners can't tell a minor HVAC issue from a serious one, and that is exactly why a proper diagnosis comes first. A system that is running but not performing correctly could have a refrigerant issue, an airflow restriction, a failing component, or a control fault. Each of those leads to a different repair, and a misdiagnosis means fixing the wrong thing. We work through the problem methodically and explain what we found before recommending anything.
A system that is running fine today can fail in the middle of a Texas summer if it has not been looked at in years. Seasonal maintenance catches the small things before they become urgent ones: dirty coils, low refrigerant, worn electrical contacts, and restricted airflow all show up on a tune-up before they cause a breakdown. We handle spring AC tune-ups and fall furnace checks, and we can also install whole-home humidifiers and dehumidifiers as part of a broader indoor air quality plan.
The region's four-season demand is hard on HVAC equipment, and a system that has been running for many years in this climate has worked for it. When replacement is the right answer, we handle the full job: removing the old equipment, installing the new system, and confirming everything is operating correctly before we leave. Heat pump installation is increasingly common here, and we install both ducted heat pumps and ductless mini-split systems depending on what the property needs. We'll get your home comfortable again fast.
We cover Mesquite and extend into the surrounding communities throughout this part of Dallas County. If your property is in any of the following areas, we can get to you:
Call and we will confirm coverage at your address. The person who answers the phone already knows the area and can give you useful information before the visit is scheduled.
the heating and cooling page describes what happens once the work starts.
Call us at (945) 356-6987 and describe what the system is doing. If the system has stopped working again after a recent service visit, we want to know about it and will come back to look at it. A return visit starts with understanding whether the original issue has returned or whether something different is causing the new problem. We do not close out a job and walk away from a system that is not performing correctly.
In most cases, yes. Duct sealing is typically done from the inside using mastic sealant or metal tape applied at the joints and connections, which does not require opening finished walls. Where the ducts are accessible through an attic, crawl space, or mechanical room, we can reach the problem areas directly. We assess the duct system first and let you know what the repair will involve before any work begins.
Yes. When we replace a system, we remove the old equipment as part of the job. You do not need to arrange separate disposal. If you have questions about what the removal covers, ask when you call for a quote and we will confirm what is included.
We need safe and reasonable access to the outdoor unit to perform any service or installation work. If access is limited by a shared driveway, a gate, or equipment placement close to a property boundary, let us know when you call. We can discuss the access situation before scheduling so the technician arrives prepared and the visit is not delayed by a problem that could have been worked out in advance.
Yes. A property manager can call to schedule service, provide access information, and receive the quote on behalf of the owner. We work with property managers across the area on both routine maintenance and emergency calls. If there are specific instructions about how the job should be handled or who needs to be contacted, let us know when you call.
Someone with access to the property and the equipment needs to be available when the technician arrives. That can be the tenant, the property owner, or a property manager, as long as they can provide access to the system and answer questions about what it has been doing. If you manage the property and cannot be there yourself, arranging for the tenant to be present is a workable alternative. Call us to discuss the setup before scheduling.
If the system is making an unusual noise, producing a burning smell, or showing signs of ice buildup, switch it off and leave it off. Running equipment that is actively failing can cause further damage or create a safety issue. If the system is simply underperforming without any of those warning signs, leaving it running is generally fine. When you call, describe what you are seeing and we can advise on the right call for your specific situation.
For most properties in this part of North Texas, yes. Humid summers put extra load on the cooling system because the equipment has to work harder to remove moisture from the air before it can lower the temperature. A whole-home dehumidifier handles that moisture separately, which reduces the demand on the AC and makes the indoor air feel more comfortable at a higher thermostat setting. We install dehumidification systems that connect to the existing HVAC equipment and cover the whole house rather than a single room.
Yes. A proper HVAC diagnosis covers both units because the indoor and outdoor components work as a connected system. A problem that shows up at the indoor air handler may be caused by a fault at the outdoor condenser, or vice versa. We check both sides as part of any diagnostic or maintenance visit so nothing is missed.
It can, because a fault in one part of a multi-zone system may affect how the rest of it performs. When you call, let us know how the property is set up and which areas are affected, and we will work through the diagnostic with that layout in mind. Properties with multiple zones or commercial setups sometimes need more time to trace a fault than a single-unit residential call, and we factor that in from the start.
One call. One technician. One fair price.
Dealing with an HVAC system before it fails is always easier than scrambling after it does. A spring tune-up before the heat builds, or a furnace check before the first real cold snap, is a much easier call to make than an emergency in the middle of the night. Tiger Air Conditioning is available around the clock, every day of the year, for both planned maintenance and urgent repairs.
