Air Conditioning Repair in San Bruno

Even if you don’t run AC daily in San Bruno, you still want it working perfectly when temperatures rise. If your AC is blowing warm air, not starting, leaking water, or cooling unevenly, we can diagnose the issue and restore proper performance.

Common AC issues we repair:

AC blowing warm air or not cooling enough
Weak airflow from vents
Uneven cooling between rooms
Frozen evaporator coil (ice buildup indoors)
Outdoor condenser not turning on or shutting off
Electrical problems (capacitors, contactors, relays, wiring)
Thermostat issues and inaccurate readings
Water leaks from clogged condensate drains

What’s a capacitor?
A capacitor helps your compressor and fan motor start and run. When it fails, your AC may click repeatedly, buzz, struggle to start, or shut off unexpectedly.

Our HVAC Services

AC Installation and Replacement

If your air conditioner is older, inefficient, or needing frequent repairs, replacement can improve comfort and reduce energy waste. Newer systems often run quieter and maintain more consistent temperatures.

Our AC installation process typically includes:

Proper sizing (comfort + efficiency, without oversizing)
Duct and airflow evaluation (for central systems)
Thermostat setup and calibration
Complete testing to confirm performance

What is short cycling?
Short cycling means your AC turns on and off too frequently. It can be caused by improper sizing, airflow restrictions, thermostat issues, or failing parts. It reduces efficiency and increases wear.

Heating Services in San Bruno

San Bruno’s cool evenings and damp air can make heating reliability essential. If your furnace won’t start, keeps shutting off, or heats unevenly, we’ll find the cause and restore safe, dependable heat.

Common furnace issues:

Furnace not turning on / no heat
Heater blowing cool air
Weak airflow and cold spots in certain rooms
Loud noises (rattling, banging, squealing)
Burning smell that doesn’t fade quickly
Frequent cycling or shutting off early
Thermostat and control board issues
Ignition or safety sensor problems

What’s a flame sensor?
A flame sensor verifies that the burner flame is present. If it’s dirty or failing, the furnace may ignite briefly and then shut down as a safety measure.

Furnace Installation and Replacement

A new furnace may be the right option if:

Repairs are happening more often
The unit is older and less efficient
Heating is uneven from room to room
You want quieter operation and better temperature control

We help you choose a properly sized heating system for your home and install it with a focus on safety and long-term reliability.

Heat Pumps and Energy-Efficient HVAC Options

Heat pumps are increasingly popular in coastal Bay Area cities because they provide both heating and cooling with strong efficiency in mild climates. For many San Bruno homeowners, a heat pump can be a modern upgrade that improves comfort while keeping energy use reasonable.

We provide:

Heat pump installation and replacement
Heat pump repair and maintenance
Ducted heat pump systems (central HVAC style)
Ductless mini-split systems for zoned comfort

What’s a ductless mini-split?
A mini-split is a ductless system with an outdoor unit connected to one or more indoor units. It’s ideal for additions, upstairs rooms, home offices, or spaces that never feel comfortable with central ducts.

Ductwork Services and Airflow Improvements in San Bruno

Comfort problems often come down to airflow. If ductwork leaks or is damaged, your system may run longer while rooms still feel uneven—especially in homes with older ducts or additions.

Ductwork services include:

Duct sealing to reduce air leakage
Repairing disconnected or damaged duct runs
Replacing collapsed or deteriorated flex duct
Improving airflow to stubborn cold or hot 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 into the rooms you live in. Sealing ducts improves comfort and reduces HVAC strain.

HVAC Maintenance and Tune-Ups in San Bruno

Preventive maintenance helps reduce breakdowns, improves efficiency, and extends equipment life—especially before the heating season and before warmer weather returns.

A typical HVAC tune-up may include:

Electrical inspections and tightening connections
Testing capacitors, contactors, and safety controls
Outdoor coil inspection/cleaning (as needed)
Blower motor inspection and airflow checks
Drain line inspection and clearing to prevent leaks
Temperature split measurement (performance check)
Thermostat testing and cycle evaluation

Temperature split explained simply:
It’s the difference between the air temperature entering your system and the air temperature leaving through the vents. It helps confirm whether your HVAC system is heating/cooling properly.

Indoor Air Quality for San Bruno Homes

Coastal air and indoor humidity can make a home feel stuffy if filtration and airflow aren’t right. Dust, pollen, and seasonal air issues can also affect comfort.

We can help with:

Filter recommendations matched to your HVAC system
Airflow balancing to reduce stuffy rooms
Maintenance plans that 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. The right filter balances filtration and airflow.
