Air Conditioning Repair in San Leandro

If your AC is blowing warm air, cooling unevenly, or running nonstop, it’s time for a professional diagnosis. Many AC problems start small—like a worn capacitor, clogged drain, or airflow restriction—and become expensive if the system keeps running under stress.

Common AC issues we repair:

AC blowing warm air or not cooling enough
Weak airflow from vents
Uneven cooling (hot rooms / cold rooms)
Frozen evaporator coil (ice buildup on the indoor unit)
Outdoor condenser not turning on or shutting off
Electrical issues (capacitors, contactors, relays, wiring)
Thermostat and sensor problems
Water leaks from clogged condensate drain lines

What’s an evaporator coil?

The evaporator coil is the indoor coil that absorbs heat from your home. If it’s dirty or frozen, cooling performance drops and leaks can happen when ice melts.

What’s a capacitor?

A capacitor helps the compressor and fan motor start and run. If it fails, the system may buzz, click repeatedly, or struggle to start.

Our HVAC Services

AC Installation and Replacement

In warmer East Bay conditions, older AC systems often struggle during peak heat. If your unit is inefficient, noisy, or frequently breaking down, replacement can improve comfort and reduce long-term operating costs.

Our AC installation process typically includes:

Proper sizing (to avoid short cycling and uneven comfort)
Ductwork and airflow evaluation for central systems
Thermostat setup and calibration
Full performance testing after installation

What is short cycling?

Short cycling is when the AC turns on and off too frequently. It can be caused by improper sizing, restricted airflow, thermostat placement issues, or failing components. It reduces efficiency and increases equipment wear.

Heating Services in San Leandro

San Leandro evenings can get chilly, and a furnace that struggles can leave parts of your home uncomfortable. If your furnace won’t turn on, blows cool air, or shuts off early, we can diagnose the issue and restore safe, reliable heat.

Common furnace problems:

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

What’s a flame sensor?

A flame sensor confirms the burner flame is present. If it’s dirty or failing, the furnace may ignite briefly and then shut down as a safety response.

Furnace Installation and Replacement

A furnace replacement may make sense if:

Repairs are becoming frequent and costly
The furnace is older and less efficient
Heating is uneven from room to room
You want quieter operation and better comfort control

We help you choose the right system size and install it for safe, dependable operation.

Heat Pumps and Energy-Efficient HVAC Options in San Leandro

Heat pumps are increasingly popular across the East Bay because they provide both heating and cooling in one efficient system. Many homeowners choose heat pumps for improved efficiency, modern comfort control, and all-electric goals.

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 home offices, additions, converted garages, and rooms that need separate temperature control.

Ductwork Services and Airflow Improvements in San Leandro

Airflow problems can make even a good HVAC system feel weak. Leaky ducts, disconnected runs, or poor distribution can cause hot/cold spots and higher bills because your system works harder than it should.

Duct services include:

Duct sealing to reduce air leaks
Repairing disconnected or damaged duct runs
Replacing collapsed or deteriorated flex duct
Improving airflow to stubborn rooms
Duct insulation recommendations (as needed)

Why duct sealing matters:

Leaky ducts can dump conditioned air into the attic or crawlspace instead of delivering it into your rooms. Sealing helps improve comfort and reduces strain on your HVAC equipment.

What’s a return vent?

A return vent pulls indoor air back into the HVAC system to be heated or cooled again. If returns are blocked or undersized, airflow suffers and comfort becomes uneven.

HVAC Maintenance and Tune-Ups in San Leandro

Preventive maintenance helps reduce breakdowns, improves efficiency, and extends the life of your equipment—especially before peak summer cooling and winter heating seasons.

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:

This is the difference between the air temperature entering your system and the air temperature coming out through your vents. It helps confirm whether your HVAC system is performing properly.

Indoor Air Quality for San Leandro Homes

Indoor air quality can be affected by dust, pollen, pets, and seasonal air conditions. Better filtration and healthy airflow can make your home feel cleaner and more comfortable—especially during warm months when the AC runs more often.

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 improvements when appropriate

Filter tip:

Higher-rated filters can improve air quality, but if they restrict airflow too much, it can reduce HVAC performance. The best filter balances filtration and airflow for your system.
