Whether your heater won’t turn on, your home has cold spots, or you want a modern, efficient upgrade, our technicians focus on long-term comfort and reliable performance.

Complete Heating and Cooling Services in Daly City

Heating Repair and Furnace Service in Daly City

Because Daly City runs cooler most of the year, heating reliability matters. If your furnace is struggling, you may notice uneven temperatures, short cycling, or a system that runs but doesn’t actually feel warm.

Common heating problems we repair:

Furnace won’t turn on / no heat
Heater blowing cool air
Weak airflow and cold rooms
Frequent cycling on/off
Loud noises (rattling, banging, squealing)
Burning smell that doesn’t fade quickly
Thermostat problems or wiring issues
Ignition and safety sensor failures

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

Our HVAC Services

Furnace Installation and Replacement

If your furnace is older, inefficient, or needs frequent repairs, replacement can improve comfort and reduce energy waste—especially in a climate where heating runs often.

A new furnace can help when:

You’re paying for repeated repairs
Your system heats unevenly
Your home feels drafty even with the heat running
You want quieter operation and better temperature control

We install properly sized heating systems and make sure airflow and thermostat control are set up correctly for your home.

Heat Pumps in Daly City

Heat pumps are a popular option in Daly City because they provide both heating and cooling while operating efficiently in mild-to-cool coastal climates. For many homeowners, a heat pump can be a smart modern upgrade—especially when paired with good airflow and insulation.

We provide:

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

What’s a ductless mini-split?
A mini-split is a ductless heating and cooling system with an outdoor unit connected to one or more indoor units. It’s great for additions, upstairs rooms, or parts of the home that never stay comfortable.

Air Conditioning Services in Daly City

Even if you don’t use AC every day in Daly City, you still want it ready when the weather warms up. If your AC is blowing warm air, leaking water, or not turning on, we can diagnose the problem and restore reliable operation.

Common AC problems we repair:

AC blowing warm air or weak airflow
Frozen evaporator coil (ice buildup)
Outdoor condenser not turning on
Electrical issues (capacitors, contactors, relays)
Thermostat issues and sensor problems
Water leaks from clogged condensate drain lines

What’s a capacitor?
A capacitor helps your AC motor(s) start and run. If it fails, the system may buzz, click, or struggle to turn on.

AC Installation and Replacement

If you want stronger cooling performance during warm spells, or your older unit is unreliable, replacement may be the best option. We install systems sized for your space and your real comfort needs—without oversizing.

What is short cycling?

Short cycling is when the AC turns on and off too frequently. It can be caused by an oversized unit, restricted airflow, thermostat placement issues, or failing parts. It reduces efficiency and wears out equipment faster.

Ductwork Services and Airflow Improvements in Daly City

Coastal homes often deal with drafts, cold spots, and humidity. Ductwork condition plays a big role in how comfortable your home feels, especially when heating runs frequently.

Ductwork services include:

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

Why duct sealing matters:
Leaky ducts can dump heated air into the attic or crawlspace instead of delivering it to your rooms. Sealing improves comfort and helps your system run more efficiently.

HVAC Maintenance and Tune-Ups in Daly City

Routine maintenance helps prevent breakdowns and keeps your system efficient—especially important when heating is used often.

A typical HVAC tune-up may include:

Electrical inspections and tightening connections
Testing capacitors, contactors, and safety controls
Inspecting blower motor and airflow
Checking thermostat operation and cycling behavior
Cleaning/rinsing outdoor coil (as needed)
Inspecting drain line and clearing clogs
Temperature split measurement (performance check)

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

Indoor Air Quality for Daly City Homes

In a cooler, coastal environment, indoor air can feel damp or stale if airflow and filtration aren’t right. Many homeowners also deal with dust, allergies, or irritation from poor ventilation.

We can help with:

Filter recommendations matched to your HVAC system
Airflow balancing to reduce stuffy areas
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, they can reduce HVAC performance. The right filter balances filtration and airflow.
