Complete Heating and Cooling Services in San Mateo
Even in cooler coastal areas, AC problems show up at the worst times—especially when the temperature spikes. If your air conditioner is blowing warm air, cooling unevenly, or leaking water, we’ll diagnose the issue and get your system running efficiently again.
Common AC issues we repair:
AC blowing warm air or not cooling enough
Weak airflow or uneven cooling between rooms
Frozen evaporator coil (ice buildup on indoor unit)
Outdoor condenser not turning on or shutting off
Electrical failures (capacitors, contactors, relays, wiring)
Thermostat and sensor problems
Water leaks from clogged condensate drains
What’s a capacitor?
A capacitor helps your AC motors start and run (like the compressor and fan motor). When it fails, the system may click, buzz, struggle to start, or shut off unexpectedly.
AC Installation and Replacement
If your AC is older, inefficient, or needs frequent repairs, replacement can improve comfort and reduce energy waste. Newer systems are often quieter, more efficient, and better at maintaining consistent indoor temperatures.
Our AC installation process typically includes:
Proper sizing (to avoid comfort issues and short cycling)
Duct and airflow evaluation for central systems
Thermostat setup and calibration
Full performance testing after installation
What is short cycling?
Short cycling means your AC turns on and off too frequently. It can happen due to improper sizing, airflow restrictions, thermostat issues, or failing components. It increases wear and reduces efficiency.
Heating Services in San Mateo
San Mateo’s evenings can get chilly—especially with moisture in the air. If your furnace won’t turn on, heats unevenly, or keeps shutting off, we can diagnose the issue and restore safe, dependable heat.
Common furnace problems:
Furnace not turning on / no heat
Heater blowing cool air
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 be the right option if:
Repairs are frequent and expensive
The unit is older and less efficient
Heating is uneven between rooms
You want improved comfort control and quieter operation
We help you choose a properly sized system that fits your home—without oversizing or unnecessary upgrades.
Heat Pumps and Energy-Efficient Options in San Mateo
Heat pumps are increasingly popular on the Peninsula because they provide both heating and cooling in one efficient system—often a great match for San Mateo’s climate.
We offer:
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 that uses an outdoor unit connected to indoor air handlers. It’s ideal for additions, home offices, and rooms that need separate temperature control—especially when ductwork is limited.
Ductwork Services and Airflow Improvements
Comfort issues often come down to airflow. If your ductwork leaks, is damaged, or isn’t balanced, you may experience hot/cold spots, weak airflow, and higher energy bills.
Duct services include:
Duct sealing to reduce air leakage
Repairing disconnected or torn duct runs
Replacing collapsed or deteriorated flex duct
Improving airflow to rooms that don’t heat/cool well
Duct insulation recommendations (as needed)
Why duct sealing matters:
Leaky ducts can send conditioned air into an attic or crawlspace instead of delivering it to your living space. Sealing improves comfort and helps your HVAC system run more efficiently.
HVAC Maintenance and Tune-Ups in San Mateo
Preventive maintenance helps reduce breakdowns, improve efficiency, and extend equipment life—especially before summer cooling demand and winter heating season.
A typical maintenance visit may include:
Electrical inspection and tightening connections
Testing capacitors, contactors, and safety controls
Outdoor coil inspection and cleaning (as appropriate)
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 coming out of your vents. It helps confirm whether your HVAC system is performing properly.
Coastal air, seasonal allergies, dust, and indoor humidity can all affect comfort. Improving filtration and maintaining proper airflow can help your indoor air feel cleaner and reduce system strain.
We can help with:
Filter recommendations matched to your 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 high-rated filter can improve air quality, but if it restricts airflow too much, it can reduce HVAC performance. The best filter balances filtration and airflow.
Call for service if you notice:
Uneven temperatures between rooms
Weak airflow from vents
AC blowing warm air or freezing up
Furnace blowing cool air or failing to start
Strange noises (buzzing, grinding, banging, squealing)
