Full Heating and Cooling Services in Sunnyvale
Air Conditioning Repair in Sunnyvale
Air Conditioning Repair in Sunnyvale
When your AC isn’t cooling like it used to, it could be a simple fix—or a warning sign that a small problem is turning into a bigger one. If you’re dealing with warm air, weak airflow, strange noises, or leaking water, we can diagnose the issue and recommend the right repair.
Common air conditioner issues we fix:
AC blowing warm air
Weak airflow from vents
Frozen indoor coil (ice buildup)
Outdoor unit not turning on
Electrical problems (capacitor, contactor, wiring)
Thermostat errors or faulty sensors
Condensate drain clogs causing water leaks
What’s a contactor?
A contactor is an electrical switch that tells your outdoor AC unit to power on and off. If it fails, the system may not start or may run inconsistently.

Air Conditioning Installation and Replacement
If your system is older, inefficient, or constantly needing repairs, replacement can improve comfort and reduce stress—especially during Sunnyvale’s warmer days.
Our AC installation approach includes:
Correct sizing (so your system cools evenly and efficiently)
Duct and airflow evaluation (for central systems)
Thermostat setup and calibration
Full performance testing after install
Why sizing matters:
An oversized unit may cool too fast and shut off before removing enough humidity (and can cause short cycling). An undersized system may run nonstop and still struggle to keep up.

Furnace Repair and Heating Troubleshooting
Furnace Repair and Heating Troubleshooting
Even in the South Bay, you’ll feel winter cold snaps—especially early mornings and nights. If your furnace won’t start, keeps shutting off, or heats unevenly, our technicians can restore safe and reliable heating.
Common furnace problems:
No heat or furnace not turning on
Heater blowing cool air
Loud operation (rattling, banging, whistling)
Frequent cycling on/off
Ignition or pilot issues (depending on system type)
Thermostat and control board problems
What’s a control board?
The control board is like the “brain” of the furnace. It manages ignition, fan timing, safety sensors, and communication with the thermostat.
Furnace Installation and Replacement
You may want to replace your furnace if:
It’s older and repairs are becoming frequent
Heating is uneven or the system struggles to reach set temperature
You want better efficiency and comfort control
Your indoor air feels dusty or airflow is poor (often tied to duct or blower issues)
We can help you choose a system that fits your home and budget, and install it with a focus on safe operation and long-term performance.
Heat Pumps and Modern Energy-Efficient Options
Heat pumps are one of the most popular upgrades in Silicon Valley and the Bay Area because they can provide both heating and cooling with strong efficiency—especially in milder climates like Sunnyvale.
We offer:
Heat pump installation and replacement
Heat pump repair and maintenance
Ducted heat pump systems (central-style)
Ductless mini-split systems (great for additions and targeted comfort)
What’s a heat pump?
A heat pump moves heat rather than generating it by burning fuel. In summer it removes heat from your home (cooling). In winter it pulls heat from outdoor air and brings it inside (heating).
Ductwork Services and Airflow Improvements
If you have central heating and cooling, your ducts are the pathways that deliver comfort. Leaky, damaged, or poorly designed ductwork can cause:
Hot and cold spots
Rooms that never feel comfortable
A system that runs longer than it should
Higher energy bills
Ductwork services include:
Duct sealing to reduce leaks
Repairing torn or disconnected duct sections
Replacing damaged flex duct
Improving airflow to problem rooms
Duct insulation recommendations (where needed)
What’s duct leakage?
Duct leakage means treated air escapes before it reaches your rooms. Sealing ducts helps you actually feel the heating and cooling you’re paying for.
HVAC Maintenance and Tune-Ups in Sunnyvale
Preventive maintenance is one of the best ways to avoid breakdowns during peak demand. A well-maintained HVAC system typically lasts longer, runs more efficiently, and has fewer surprise failures.
A typical maintenance visit may include:
Electrical checks (tightening connections, testing components)
Outdoor coil cleaning (as needed)
Inspecting blower motor and airflow
Checking temperature split (performance check)
Inspecting and clearing drain lines
Verifying thermostat operation and cycling patterns
Reviewing overall system condition and safety
Temperature split explained simply:
It’s the difference between the air temperature going into your system and the air coming out. It helps show whether the system is doing its job properly.
Indoor Air Quality Support for Sunnyvale Homes
Indoor Air Quality Support for Sunnyvale Homes
Indoor air quality matters—especially if your household deals with allergies, dust, or seasonal smoke conditions. HVAC improvements can help your air feel cleaner and reduce buildup inside the system.
Options we can assist with:
Higher-quality air filter recommendations
Airflow balancing to reduce stuffy rooms
HVAC cleaning guidance and maintenance plans
System add-ons (only when they genuinely fit your needs)
Simple tip:
A better filter helps, but only if your system can handle it. Too restrictive of a filter can reduce airflow and strain the system—so it’s best to match filtration to your equipment.
