Not sure which service you need? Tell us what your system is doing, and we will help you determine the right next step.
From failed capacitors and clogged drain lines to refrigerant leaks and electrical problems, we diagnose and repair most central air-conditioning system issues.
When an aging air conditioner becomes unreliable or expensive to repair, we can help you compare replacement options before recommending equipment.
Routine system maintenance can uncover developing problems, improve system operation and reliability, and to reduce the risk of preventable breakdowns.
When cold weather reaches Houston, we provide furnace and heating repair, maintenance, and replacement services to restore safe, dependable heat.
We install residential heating systems selected for the home’s needs. We will explain the proposed equipment and installation scope before work begins.
Seasonal heating maintenance helps identify ignition, airflow, electrical, safety, and performance concerns before colder weather arrives.
Leaking, damaged, or poorly designed ductwork can contribute to uneven temperatures. We evaluate the duct system.
An HVAC Zoning system may be useful for multi-story homes, large floor plans, seldom-used rooms, or areas with different heating and cooling loads.
Ductless mini-splits can provide targeted heating and cooling without practical access to central ductwork.
Air filtration, air purification, ventilation, and duct improvements may help address indoor air concerns.
Several AC problems can create similar symptoms. These resources explain common causes, safe steps you can take, and when to request professional service.
Is your air conditioner running without cooling the house? The problem could involve restricted airflow, low refrigerant, a dirty evaporator coil, or a failing system component.
Learn About an AC That Isn’t Cooling
Warm air coming from the vents may be caused by a thermostat setting, electrical failure, refrigerant problem, frozen coil, or outdoor unit malfunction.
Find Out Why Your AC Is Blowing Warm Air
Ice on the refrigerant lines or indoor coil usually indicates restricted airflow, low refrigerant, or another condition that requires professional diagnosis.
Get Help With a Frozen AC Unit
If your system will not start, the cause may be a tripped breaker, thermostat problem, clogged safety switch, failed capacitor, or electrical component.
Troubleshoot an AC That Won’t Turn On
Water around the indoor equipment can result from a clogged condensate drain, damaged drain pan, frozen evaporator coil, or condensate pump failure.
Learn Why Your AC Is Leaking Water
If the indoor fan runs but the outdoor unit does not, your air conditioner may have a failed capacitor, contactor, fan motor, electrical connection, or compressor.
Get Help With an Outside Unit That Isn’t Running
You do not need to diagnose the equipment yourself. If the system is not operating normally, call Modern Air of Katy and tell us what you are experiencing.
We base our recommendations on the condition of your equipment, the results of our testing, your comfort concerns, and the value of the available options.
A repairable system does not automatically need to be replaced because it is older. When both repair and replacement are reasonable options, we explain the factors that can help you decide.
We explain the diagnosis and recommended work before beginning an approved repair or installation.
Comfort problems do not always originate with the most obvious component. Depending on the symptoms, we may evaluate equipment operation, electrical components, refrigerant performance, drainage, ductwork, airflow, thermostats, and controls.

Let us know what the system is doing, when the problem began, and whether you need repair, maintenance, or an installation estimate.
Our technician inspects and tests the components and operating conditions related to your concern. For installation projects, we also evaluate the home, existing system, airflow, and comfort priorities.
You receive a straightforward explanation of the system’s condition and the reason for our recommendation. We answer your questions without relying on confusing technical language.
We explain the recommended work and practical alternatives before approved work begins. If you are facing a major repair, we can help you compare repair and replacement without pressure.
After completing the approved service, we test the applicable equipment and confirm that it is operating properly.
A broken air conditioner does not automatically require replacement. Repair is often appropriate when the failed component is replaceable, the equipment has otherwise been dependable, and the repair cost is reasonable compared with the system’s condition and remaining value.
Replacement may deserve consideration when the equipment is approximately 10–15 years old, repairs are becoming frequent, a major component has failed, comfort has declined, or the current repair represents a poor investment in an aging system.
Important factors include:
Equipment age and overall condition
Type and cost of the current repair
Previous repair history
Refrigerant type and parts availability
Warranty coverage
Cooling and humidity performance
Energy consumption
Likelihood of additional repairs
We will explain what we find and help you evaluate the options.
Houston’s long cooling season places considerable demand on capacitors, condenser fan motors, compressors, drain systems, and evaporator coils. High humidity can also contribute to condensate drainage problems, biological buildup, and comfort issues.
Homes in established West Houston neighborhoods may have additional challenges, including aging ductwork, equipment additions, insulation deficiencies, airflow restrictions, or rooms that are consistently warmer than the rest of the house.
We evaluate the complete comfort system instead of assuming every cooling problem requires a larger air conditioner. Depending on the home, the right solution may involve repairing the existing equipment, correcting airflow, sealing ductwork, improving filtration, or replacing an aging system.
Preventive maintenance cannot eliminate every breakdown, but it can identify many developing problems before they interrupt your comfort. Regular service is particularly valuable in Houston because cooling equipment operates for much of the year.
Maintenance may help uncover:
Weak electrical components
Loose or damaged wiring
Restricted airflow
Dirty coils
Condensate drainage problems
Abnormal motor operation
Heating safety concerns
Temperature and performance issues

Same-day appointments are frequently available depending on your location, the time you call, technician availability, and current demand. Availability may be limited during extreme heat, so calling earlier is recommended.
We serve Spring Branch, Memorial, Briar Forest, the Energy Corridor, Westchase, the Memorial Villages, Katy, and surrounding communities. Contact us if you are unsure whether your home is within our current service area.
We service most major brands of residential central air conditioners, heat pumps, furnaces, and related HVAC equipment. Contact us with your system information if you have questions about a particular brand or equipment type.
The answer depends on the system’s age and condition, the repair cost, previous breakdowns, warranty coverage, refrigerant type, efficiency, and comfort performance. We recommend repair when it represents a sensible investment and discuss replacement when the equipment’s condition and costs justify it.
Most Houston systems should receive professional maintenance twice per year: once before the primary cooling season and once before heating season. The appropriate schedule can also depend on the equipment, household conditions, and manufacturer requirements.
We provide estimates for qualifying HVAC installation and replacement projects. Contact Modern Air of Katy to confirm current estimate terms and schedule an evaluation.
Possible causes include restricted airflow, a dirty or frozen evaporator coil, low refrigerant, an electrical problem, or an outdoor-unit failure. Because several problems can produce the same symptom, the system should be tested before parts are replaced.
Whether you need urgent AC repair, preventive maintenance, heating service, ductwork help, or a replacement estimate, Modern Air of Katy is ready to help.
