Air Conditioning Repair in San Carlos
Air Conditioning Repair in San Carlos
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 an electrical part wearing out, a dirty coil, or a clogged drain line—and become bigger if ignored.
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 issues (capacitors, contactors, relays, wiring)
Thermostat and sensor problems
Water leaks from clogged condensate drains
What’s a contactor?
A contactor is an electrical switch that sends power to the outdoor AC unit when the thermostat calls for cooling. If it fails, your system may not turn on—or may run inconsistently.

Our HVAC Services
AC Installation and Replacement
If your air conditioner is older, inefficient, or frequently breaking down, replacement can improve comfort and reduce long-term operating costs. Newer systems often run quieter, maintain steadier temperatures, and waste less energy.
Our AC installation process typically includes:
Proper sizing (to avoid short cycling and uneven comfort)
Duct and airflow evaluation for central systems
Thermostat setup and calibration
Full system 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 issues, or failing parts. It reduces efficiency and increases equipment wear.
Heating Services in San Carlos
San Carlos evenings can cool down fast, especially in winter. If your furnace won’t start, keeps shutting off, or heats unevenly, we can diagnose the issue and restore safe, dependable heat.
Common furnace issues:
Furnace not turning on / no heat
Heater blowing cool air
Weak airflow and cold spots
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 measure.
Furnace Installation and Replacement
A furnace replacement may make sense if:
Repairs are becoming frequent and costly
The system is older and less efficient
Heating is uneven from room to room
You want quieter operation and improved comfort control
We help you choose the right system size and install it for safe, reliable performance.
Heat Pumps and High-Efficiency HVAC Options
Heat pumps are increasingly popular in San Carlos and across the Peninsula because they provide both heating and cooling in one efficient system—often a great match for the Bay Area climate.
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 air handlers. It’s ideal for additions, home offices, upstairs rooms, and spaces that need separate temperature control.
Ductwork Services and Airflow Improvements in San Carlos
Comfort problems are often airflow problems. If ductwork leaks, is damaged, or isn’t balanced properly, your system may run longer while your rooms still feel uneven.
Duct services include:
Duct sealing to reduce air leakage
Repairing disconnected or damaged duct runs
Replacing collapsed or deteriorated flex duct
Improving airflow to problem rooms
Duct insulation recommendations (as needed)
Why duct sealing matters:
Leaky ducts can dump conditioned air into attic or crawlspace areas instead of delivering it into your living space. Sealing improves comfort and helps your system run more efficiently.
HVAC Maintenance and Tune-Ups in San Carlos
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 inspection 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 the HVAC system is heating/cooling properly.
Indoor Air Quality for San Carlos Homes
Indoor Air Quality for San Carlos Homes
Indoor air quality can be affected by dust, pollen, pets, and seasonal air concerns. Better filtration and proper airflow can help your home feel cleaner and more comfortable.
We can help with:
Filter recommendations matched to your system
Airflow balancing to reduce stuffy rooms
Maintenance plans that keep components cleaner
Optional IAQ upgrades when appropriate
Filter tip:
Higher-rated filters can improve air quality, but if they restrict airflow too much, it can reduce HVAC performance. The right filter balances filtration and airflow.
