Full Heating and Cooling Services in Milpitas
If your air conditioner is running but not cooling, blowing warm air, or leaking water, it’s time to get it checked. Many AC issues start small (like a weak capacitor or clogged drain line) and grow into expensive repairs if ignored.
Common AC problems we fix:
AC blowing warm air
Weak airflow or uneven cooling
Frozen evaporator coil (ice on indoor unit)
Outdoor condenser not starting or shutting off
Electrical issues (capacitor, contactor, relay, wiring)
Thermostat problems and sensor failures
Water leaks from clogged condensate drains
What’s a condensate drain?
Your AC removes humidity from the air, and that moisture drains out through a condensate drain line. If it clogs, water can back up and leak around the indoor unit.
AC Installation and Replacement
Older systems may still run, but they often work harder than they should—leading to higher bills, noisier operation, and uneven comfort. Replacing your AC can mean better efficiency and better temperature control throughout the home.
Our installation process typically includes:
Proper sizing (to avoid comfort problems and short cycling)
Duct and airflow evaluation (for central systems)
Thermostat setup and calibration
System testing to confirm performance
What is short cycling?
Short cycling happens when the AC turns on and off too frequently. This can be caused by improper sizing, restricted airflow, thermostat problems, or failing components. It wastes energy and increases wear on your system.
Heating and Furnace Services in Milpitas
Milpitas winters can still bring chilly nights, and a heater that’s unreliable makes the whole home feel uncomfortable. If your furnace won’t start, blows cool air, or cycles on and off too often, we’ll find the cause and fix it safely.
Common furnace issues:
No heat / furnace won’t turn on
Heater blowing cool air
Rattling, banging, or squealing noises
Burning smell that doesn’t go away
System shuts off shortly after starting
Thermostat and control issues
Ignition problems (depending on furnace type)
What’s a flame sensor?
A flame sensor is a safety device that confirms the burners are lit. If it’s dirty or failing, the furnace may ignite briefly and then shut off.
Furnace Installation and Replacement
A furnace replacement may make sense if:
You’re paying for frequent repairs
The unit is older and struggling to keep up
Heating is uneven from room to room
You want improved efficiency and quieter operation
We help you choose a system that fits your home—without overselling equipment you don’t need.
Heat Pumps and High-Efficiency Upgrades
Heat pumps are becoming more common across the Bay Area because they provide heating and cooling in one system and can offer excellent efficiency in milder climates like Milpitas.
We provide:
Heat pump installation and replacement
Heat pump repairs and maintenance
Ducted heat pump systems (central HVAC style)
Ductless mini-split systems (room-by-room zoning)
What’s a ductless mini-split?
A ductless mini-split uses an outdoor unit connected to indoor air handlers, allowing targeted comfort in specific areas like bedrooms, home offices, additions, and converted garages—without relying on ductwork.
Ductwork Services and Airflow Improvements
If your home has central HVAC, your ducts play a huge role in comfort. Duct issues can cause:
Hot rooms and cold rooms
Weak airflow in certain areas
A system that runs longer than necessary
Dustier air and higher energy use
Ductwork services include:
Duct sealing to reduce air loss
Repairing disconnected or torn duct runs
Replacing collapsed or deteriorated flex ducts
Improving airflow to problem rooms
Duct insulation recommendations (as needed)
Why duct sealing matters:
Leaky ducts can dump conditioned air into the attic or crawlspace. Sealing ducts helps you feel more comfort in your living space and reduces strain on the HVAC system.
HVAC Maintenance and Tune-Ups in Milpitas
Routine maintenance keeps your system efficient, helps reduce breakdowns, and extends equipment life—especially before peak summer heat and winter cold snaps.
A typical maintenance visit may include:
Electrical component inspection and tightening connections
Outdoor coil cleaning/rinsing (as appropriate)
Blower motor inspection and airflow checks
Thermostat testing and cycle evaluation
Drain line inspection and clearing
Temperature split measurement (performance check)
Safety checks for heating operation
Temperature split (simple explanation):
This is the difference between the air temperature entering your system and the air coming out of your vents. It helps confirm whether your HVAC system is cooling or heating properly.
Indoor air quality can be affected by dust, pollen, pets, and seasonal air issues. Better filtration and proper airflow can make a noticeable difference—especially for families with allergies or sensitive breathing.
We can assist with:
Filter recommendations (matched to your system)
Airflow improvements to reduce stuffy areas
Maintenance plans that keep components cleaner
Optional IAQ upgrades when appropriate
Important note about filters:
A higher-rated filter isn’t always better if it restricts airflow too much. The best filter is one that improves air quality while still allowing healthy airflow.
Call for HVAC service if you notice:
Uneven temperatures between rooms
Weak airflow from vents
AC blowing warm air or freezing up
Heater blowing cool air or failing to start
Strange noises (buzzing, grinding, banging, squealing)
Water leaks around the indoor unit
Frequent cycling or nonstop operation
Rising energy bills without a clear reason
Thermostat settings don’t match comfort
Honest diagnostics and practical recommendations
Repair vs. replace guidance (no pressure)
Focus on comfort + efficiency, not just quick fixes
