Air Conditioning Repair in Cupertino
Air Conditioning Repair in Cupertino
When your air conditioner isn’t doing its job, you’ll usually notice it right away: warm air from vents, weak airflow, rooms that cool unevenly, or a system that runs constantly but never seems to catch up. We diagnose the cause and repair the system properly—so you don’t keep paying for the same problem.
Common AC issues we repair:
AC blowing warm air
Weak airflow and uneven cooling
Frozen indoor coil (ice on the evaporator coil)
Outdoor condenser not turning on
Electrical problems (capacitors, contactors, relays, wiring)
Thermostat and sensor issues
Water leaks caused by clogged drain lines
What’s a capacitor?
A capacitor is an electrical component that helps motors start and run (like the fan motor and compressor). When it fails, the unit may struggle to start, shut off unexpectedly, or make buzzing/clicking sounds.

AC Installation and Replacement
If your AC is older, inefficient, or frequently breaking down, a new system can improve comfort and reduce long-term operating costs—especially during warmer Cupertino days.
Our AC installation process typically includes:
Proper system sizing for your home and layout
Airflow and duct evaluation (for central systems)
Thermostat setup and calibration
Complete testing to confirm performance
What is short cycling?
Short cycling means the AC turns on and off too frequently. This can be caused by incorrect sizing, restricted airflow, thermostat issues, or failing components. It increases wear and can raise your energy bills.
Heating Services in Cupertino
Cupertino winter nights can still feel cold—especially in homes with uneven airflow or rooms that run cooler than others. If your furnace won’t start, keeps shutting off, or doesn’t heat consistently, we can diagnose and fix the issue safely.
Common furnace problems:
Furnace not turning on
Heater blowing cool air
Loud noises (rattling, banging, squealing)
Frequent on/off cycling
Ignition or pilot issues (depending on model)
Thermostat communication problems
Safety sensor and control issues
What’s a flame sensor?
A flame sensor confirms the burner flame is present. If it gets dirty, the furnace may ignite briefly and then shut off as a safety response.
Furnace Installation and Replacement
A furnace replacement may be the best option when:
Repairs are becoming frequent and expensive
The furnace is older and efficiency is low
Your home heats unevenly
You want quieter operation and improved comfort control
We help you compare options and choose the right fit—without oversizing or unnecessary upsells.
Heat Pumps and High-Efficiency HVAC Upgrades
Heat pumps are increasingly popular throughout Cupertino because they provide both heating and cooling using one system and can be very efficient in the Bay Area’s mild climate. Many homeowners also choose them to move toward an all-electric home.
We provide:
Heat pump installation and replacement
Heat pump repairs and maintenance
Ducted heat pumps (central HVAC style)
Ductless mini-split systems for zoned comfort
What’s a ductless mini-split?
A mini-split is a ductless system that uses an outdoor unit connected to one or more indoor units. It’s perfect for home offices, additions, guest suites, and rooms that need their own temperature control.
Ductwork Services and Airflow Improvements
Your HVAC system can only perform as well as the airflow allows. Even a great unit will struggle if ducts leak, are disconnected, or aren’t balanced properly. Duct problems often show up as hot/cold spots, weak airflow, or higher utility bills.
Ductwork services include:
Duct sealing to reduce leaks
Repairing torn or disconnected duct runs
Replacing damaged flex duct sections
Improving airflow to problem rooms
Duct insulation recommendations (as needed)
Why duct sealing matters:
Leaky ducts can dump conditioned air into an attic or crawlspace instead of delivering it to your living areas. Sealing helps improve comfort and reduces strain on the system.
HVAC Maintenance and Tune-Ups in Cupertino
Preventive maintenance is one of the smartest ways to avoid mid-season breakdowns and keep your system running efficiently. A tune-up can also reveal small issues before they become expensive repairs.
A typical maintenance visit may include:
Electrical inspections and tightening connections
Testing capacitors, contactors, and safety controls
Cleaning/rinsing the outdoor coil (as appropriate)
Inspecting blower motor and airflow performance
Checking temperature split (heating/cooling performance)
Clearing drain lines to prevent water leaks
Thermostat testing and cycle evaluation
Temperature split explained simply:
It’s the difference between the air temperature entering your system and the air temperature coming out of your vents. It helps confirm whether your system is working properly.
Indoor Air Quality for Cupertino Homes
Indoor Air Quality for Cupertino Homes
Indoor air quality can be affected by dust, pollen, pets, and seasonal air issues. The right filtration and airflow can help your home feel cleaner and more comfortable—especially for families with allergies.
We can help with:
Filter recommendations matched to your system
Airflow balancing to reduce stuffy rooms
Maintenance plans to keep internal components cleaner
Optional IAQ upgrades when appropriate for your home
Filter tip:
A higher-rated filter can improve air quality, but if it restricts airflow too much, it can reduce HVAC performance. We’ll help you find the right balance.
