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

Let us know what your air conditioner is doing, when the problem began, and whether the system is still operating. This information helps us prepare for the service call.
Our technician inspects the system and tests the appropriate components. We look beyond the first visible symptom to determine what failed and whether another condition contributed to the problem.
You receive a straightforward explanation of the diagnosis. We will show you the problem when practical and answer your questions without confusing technical language.
We explain the recommended repair and available alternatives before beginning the work. If the system is aging or the repair is unusually expensive, we can also help you compare repair and replacement.
After completing an approved repair, we test system operation and confirm that the equipment is cooling and operating properly.
We identify the actual cause of the problem and explain our findings before recommending a solution.

Schedule AC Maintenance
Repair is often the sensible choice when the air conditioner is otherwise dependable, the failed part is replaceable, and the repair cost is reasonable compared with the system’s value.
Replacement may deserve consideration when the equipment is approximately 10–15 years old, requires increasingly frequent repairs, has a major refrigerant or compressor problem, or no longer keeps the home comfortable.
We consider several factors before making a recommendation:
Age and overall condition of the system
Cost and type of the current repair
Previous repair history
Energy efficiency and operating costs
Comfort and humidity control
Equipment and parts warranty coverage
Likelihood of additional repairs
Modern Air of Katy will explain the condition of your existing equipment and provide the information you need to decide without sales pressure.
Read Our Repair vs. Replace Your Air Conditioner Guide
Planning for a new system? Review the factors that affect AC replacement costs in Houston before requesting estimates.
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.
Houston air conditioners operate for much of the year. Regular professional maintenance helps identify worn components, drainage problems, airflow restrictions, and other conditions before they cause an unexpected breakdown.

An air conditioner can run without cooling because of restricted airflow, a dirty evaporator or condenser coil, low refrigerant, a frozen coil, an outdoor-unit failure, or another mechanical or electrical problem. Proper testing is needed to identify the cause.
Yes. Continuing to operate a frozen air conditioner can prevent the ice from melting and may place additional strain on the system. Turn cooling off at the thermostat and leave the fan set to “On” if it is still moving air. Do not attempt to remove ice with tools or heat.
Yes. We diagnose refrigerant-related problems and determine whether the system has a repairable leak. Adding refrigerant without investigating why it was lost does not correct the underlying problem.
We service and repair most major residential HVAC brands and system types, including central air conditioners, heat pumps, gas furnaces, and ductless mini-split systems.
Most Houston HVAC systems should receive professional maintenance twice per year: once before the primary cooling season and once before heating season. Regular maintenance is particularly important because Houston air conditioners operate heavily for much of the year.
Possibly. Age alone does not determine whether replacement is necessary. The repair cost, system condition, refrigerant type, warranty status, efficiency, and previous repair history should all be considered.
We provide estimates for qualifying HVAC installation and replacement projects. Diagnostic or repair service calls may involve a service or diagnostic charge. Contact us for current details.
