Memorial includes established homes, remodeled properties, townhomes, condominiums, and larger residences with multiple HVAC systems. Different construction periods, additions, attic layouts, duct systems, and comfort controls can create very different heating and cooling needs.
Modern Air of Katy is based nearby in Spring Branch. We evaluate the complete comfort system instead of assuming every problem requires a larger air conditioner or full equipment replacement.
Depending on what we find, the appropriate solution may involve repair, maintenance, equipment replacement, duct modification, airflow correction, zoning, thermostat controls, or another targeted improvement.
When an air conditioner stops cooling during a Houston summer, proper diagnosis matters. Similar symptoms can be caused by very different electrical, mechanical, drainage, airflow, or refrigerant problems.
Our technicians inspect and test the equipment to identify the likely cause. Depending on the symptoms, this may include checking temperatures, airflow, electrical components, motors, controls, drainage, coils, and the refrigerant circuit.
We repair most major brands of residential central air conditioners, heat pumps, and related cooling equipment.
If your system operates but the home remains warm, the cause may involve restricted airflow, a dirty or frozen evaporator coil, low refrigerant, failed outdoor equipment, or another condition preventing heat removal.
Learn why your AC is not cooling
Warm air from the vents may result from an incorrect thermostat setting, electrical failure, refrigerant problem, frozen coil, outdoor-unit malfunction, or compressor trouble.
Find out why your AC is blowing warm air
A system that will not start may have a thermostat problem, tripped breaker, clogged drain safety switch, failed capacitor, damaged contactor, loose connection, or control-board issue.
Troubleshoot an AC that will not turn on
Water near indoor equipment may come from a clogged condensate line, frozen evaporator coil, damaged drain pan, failed condensate pump, or improper drainage.
Learn why your AC is leaking water
Ice on the evaporator coil or refrigerant line commonly indicates restricted airflow, a blower problem, dirty filter, low refrigerant, or another heat-transfer problem. Turn cooling off and arrange an inspection instead of using tools or direct heat to remove the ice.

If the indoor blower operates but the outdoor equipment does not, the problem may involve a capacitor, contactor, condenser fan motor, electrical supply, safety control, or compressor.

Weak airflow and hot rooms can be connected to the filter, evaporator coil, blower, ductwork, return-air system, dampers, equipment settings, insulation, sun exposure, or zoning.
Long cycles can be normal during extreme Houston heat. Continuous operation combined with poor cooling may indicate dirty equipment, restricted airflow, low refrigerant, duct leakage, insufficient capacity, or declining system performance.
Not sure which problem you have? Tell us what the system is doing, and we will take it from there.
Capacitors help start and operate motors, while contactors control power to important outdoor components. Failed electrical parts can prevent startup, cause intermittent operation, or produce humming and clicking sounds.
The condenser fan removes heat from the outdoor unit. A failed motor can cause overheating, poor cooling, or a protective shutdown.
The indoor blower moves conditioned air through the ducts. Blower problems may cause weak airflow, uneven temperatures, noise, overheating, or a frozen coil.
Air conditioners do not normally consume refrigerant. A low level may indicate a leak that should be located and evaluated. Repeatedly adding refrigerant without investigating why it was lost does not correct the underlying problem.
Houston’s humidity causes AC systems to remove substantial moisture. Algae, dirt, and debris can restrict the drain, cause water leakage, or activate a safety switch that shuts down cooling.
Incorrect temperature readings, blank screens, short cycling, or systems that fail to respond may result from thermostat, sensor, wiring, transformer, or control problems.
Coils and compressors are major components. Before recommending a major repair, we consider the failed part, supporting components, refrigerant circuit, equipment age, warranty status, and overall system condition.
Poor airflow may originate in filters, coils, blowers, restrictive returns, damaged ducts, closed dampers, or incorrect settings.
Check the thermostat. Confirm it is set to “Cool” below the current room temperature.
Inspect the air filter. A severely restricted filter can reduce airflow and contribute to coil freezing.
Check the breaker once. If it trips again after one reset, leave it off and request service.
Look for ice or water. Turn cooling off when ice or potentially damaging water is present.
Listen for unusual sounds. Grinding, buzzing, or repeated clicking may indicate an electrical or component problem.
Do not open electrical panels. HVAC equipment contains high voltage and capacitors that may retain a charge.
If the system still does not operate normally, call for professional service.
Tell us what the system is doing, when the problem began, and whether you noticed water, ice, noise, or odors.
We evaluate the components and operating conditions related to the symptoms rather than replacing the first questionable part.
We look for what failed and whether another condition contributed to the problem.
You receive a straightforward explanation of what we found and can review the relevant repair options.
We explain the recommended repair and reasonable alternatives before approved work begins.
After completing the approved repair, we test the system and confirm its operation.
Repair cost depends on the failed component, diagnostic requirements, equipment accessibility, parts availability, refrigerant type, warranty coverage, and overall condition.
A straightforward electrical or drainage repair generally costs less than locating a refrigerant leak, replacing a motor, or addressing a major component failure. An on-site diagnosis is normally required to provide accurate repair options.

Diagnostic and repair visits do not involve a service charge. Contact Modern Air of Katy for current pricing and appointment details.
When an aging air conditioner becomes unreliable or expensive to repair, we help homeowners compare replacement options. We consider:
Appropriate equipment capacity
Single-stage, two-stage, or variable-capacity operation
Equipment efficiency
Air conditioner versus heat pump
Furnace or air-handler requirements
Existing ductwork and return airflow
Thermostat and controls
Humidity-control priorities
Electrical and drainage requirements
Installation accessibility
Manufacturer warranty coverage
Budget and expected ownership period
The best system is not automatically the largest or most expensive one. It should be selected and installed for the home’s actual cooling requirements.
A broken system does not automatically need replacement. Repair may be appropriate when the equipment is otherwise dependable, the failed component is replaceable, useful warranty coverage remains, and the cost is reasonable compared with its condition and remaining value.
Replacement may deserve consideration when:
The system is approximately 10–15 years old or older
Repairs are becoming increasingly frequent
A compressor, evaporator coil, or another major component has failed
Parts or refrigerant are difficult or expensive to obtain
Manufacturer warranty coverage has expired
The system struggles to cool or control humidity
The repair cost is high compared with the equipment’s remaining value
Additional major repairs appear likely
There is no single age or repair percentage that decides every situation.
Professional maintenance cannot prevent every failure, but it may identify developing electrical, drainage, airflow, safety, and performance concerns before they interrupt comfort.
Cooling-season maintenance may include inspecting accessible electrical components, drainage, coils, filters, airflow, motors, temperatures, and system operation.
Heating-season maintenance may include checking thermostat response, electrical components, ignition and burner operation when applicable, safety controls, airflow, and blower operation.

.
Some Memorial homes use separate systems for floors, wings, or living areas. Each system should be evaluated based on the space it serves while controls and airflow should work together across the home.
Room additions, remodeled kitchens, raised ceilings, converted spaces, and window or insulation changes can alter heating and cooling requirements. Existing equipment and ducts may not have been modified when the home changed.
Attic heat, damaged duct insulation, air leakage, disconnected sections, and restrictive transitions can reduce comfort and system performance.
Air conditioners must remove both heat and moisture. Oversized equipment, short cycling, airflow restrictions, duct leakage, and declining performance can contribute to uncomfortable humidity.
Temperature differences may result from sun exposure, windows, insulation, air leakage, duct design, return placement, equipment settings, or zoning. A larger system is not automatically the correct solution.
Our Spring Branch location gives Memorial homeowners a nearby option for residential heating and cooling service.
We identify the likely cause and explain our findings before recommending a solution.
We consider repair cost, system condition, history, warranty, comfort, and remaining value instead of recommending replacement based only on age.
When repair and replacement are both reasonable options, we explain the tradeoffs and let you decide.
We consider equipment, ductwork, airflow, controls, humidity, and the home rather than assuming every comfort problem has the same cause.
