(281) 270-9551Houston’s Gulf Coast heat and thick humidity put real stress on home comfort, especially during long cooling seasons that seem to stretch on forever. When a summer heat wave hits Harris County, an AC failure can turn a normal afternoon into a sweltering one, while a winter cold snap can strain a heating system just enough to leave rooms chilly overnight. That kind of breakdown does more than make people uncomfortable, since it can drive up energy bills, leave upstairs rooms damp and stuffy, and make sleep hard when the air stops moving right. Cold Air Heating & AC helps by finding the real cause fast, whether that means a clogged condensate drain, a weak blower, a bad capacitor, or a refrigerant problem, so your home gets back to steady cooling and dependable indoor comfort.
What Makes Us Better
Fast response, honest diagnosis, upfront pricing - every job.
We trace every failure to the actual source before quoting a repair. You do not pay to replace components that are not the cause of the problem.
We service every component of your heating and cooling system - from the outdoor unit to the air handler to the ductwork - so every room stays comfortable.
Every technician is licensed and certified. We work on all major brands and explain every step before starting any repair or replacement.
We focus on residential heating and cooling systems. Your home's comfort is the job, and our technicians know the equipment installed in local homes.
When heating or cooling fails, our technicians respond quickly, run a full diagnostic, and explain exactly what they found. Written pricing before any repair begins - no pressure, no surprises.
When your air conditioner stops cooling, our licensed technicians arrive prepared to diagnose every component - compressor, refrigerant charge, capacitors, electrical - and explain what they find before any repair starts.
Our technicians diagnose heating failures accurately, checking refrigerant, electrical faults, compressor condition, and heat pump controls, then give a written repair price before any work begins.
New AC installation is a long-term investment. Our technicians help you choose the right equipment for your home, provide a written price before ordering anything, and test the full system after installation.
When a heat pump needs replacement, our technicians assess your home, explain the equipment options, provide a written price, and complete a full test run after installation.
Preventive maintenance is the most cost-effective HVAC service you can schedule. Our technicians inspect, clean, and tune your system and document everything found so you always know the state of your equipment.
Air duct cleaning is most valuable after home renovations, long periods without service, or when occupants notice increased dust or reduced airflow. We inspect, clean, and test every accessible duct run before the job is done.
Heat pumps provide both heating and cooling but require specialized diagnosis when they fail to switch modes, lose efficiency, or stop producing heat in cold weather. We service all major heat pump brands, troubleshooting reversing valves, refrigerant charge, defrost cycles, and compressor issues, and restore full heating and cooling function.
A smart thermostat gives you precise control over your home's temperature from any device. We install and configure all major brands - Nest, Ecobee, Honeywell, and more - so your system runs efficiently and you only heat or cool when you need to.
Whole-home air purifiers and advanced filtration systems remove allergens, dust, pet dander, mold spores, and airborne bacteria from the air your family breathes. We install units that integrate directly with your existing HVAC system for continuous, low-maintenance air quality improvement.
Too much or too little humidity causes comfort problems, damages wood floors and furniture, and strains your HVAC system. We install whole-home humidifiers and dehumidifiers that automatically maintain the right balance year-round without portable units or constant adjustment.
Leaky ductwork forces your HVAC system to work harder, raises energy bills, and pushes conditioned air into unconditioned spaces like attics and crawlspaces. We locate and seal leaks using professional-grade mastic or aeroseal methods to restore airflow efficiency and improve system performance.
Damaged, collapsed, or poorly designed ductwork causes uneven temperatures, reduced airflow, and increased wear on your equipment. We repair failing duct sections or design and install new duct systems that deliver balanced airflow to every room in the home.
Boilers provide reliable radiant heat but require specialized diagnosis and repair when problems arise. We service all major boiler brands, troubleshoot pressure, circulation, and ignition issues, and install new high-efficiency boiler systems when replacement is the right call.
UV air sanitizers use ultraviolet light to neutralize mold, bacteria, and viruses as air circulates through your HVAC system. We install UV systems directly in the air handler or ductwork for continuous, chemical-free air sanitation that runs quietly in the background.
Commercial HVAC systems run harder and require faster response when equipment fails. We service rooftop units, split systems, and packaged equipment for small offices, retail spaces, and light commercial properties - with the same diagnostic-first approach we apply to every job.
We do not touch your system until you approve the price.
We start with a full system inspection before recommending anything. No repair is scoped until we understand what actually failed.
You see a written quote before any repair begins. The number you approve is the number on the invoice.
We repair the root cause using quality parts matched to your equipment. No unnecessary replacements.
We run the full system before leaving to confirm the repair is holding and performance is restored.
