Complete Heating and Cooling Services in Berkeley
Even in a generally mild climate, AC issues can feel urgent when the temperature rises—especially in upper floors, sun-facing rooms, or homes with limited airflow. If your AC is blowing warm air, cooling unevenly, leaking water, or not turning on, we’ll diagnose the problem and restore dependable cooling.
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 drain lines
What’s an evaporator coil?
The evaporator coil is the indoor coil that absorbs heat from your home. If it gets dirty or freezes, cooling drops and leaks can occur when ice melts.
What’s a capacitor?
A capacitor helps the compressor and fan motor start and run. When it fails, your system may buzz, click repeatedly, or struggle to start.
AC Installation and Replacement
If your AC is older, inefficient, or frequently breaking down, replacement can improve comfort and reduce energy waste. In Berkeley homes, proper sizing and airflow planning matter a lot—especially in multi-level homes where upstairs areas warm up faster.
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 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 wear.
Heating Services in Berkeley
Berkeley evenings and winter mornings can feel cold—especially in homes with drafts, older windows, or uneven airflow. If your furnace won’t start, keeps shutting off, or doesn’t heat consistently, we can diagnose the issue and restore safe, dependable heat.
Common furnace problems:
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 or 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 be a good option if:
Repairs are becoming frequent and costly
The unit 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 Energy-Efficient HVAC Options in Berkeley
Heat pumps are increasingly popular in Berkeley because they provide both heating and cooling in one system and can be very efficient in a Bay Area climate. Many homeowners also choose heat pumps for modern comfort control and electrification 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 heating and cooling system with an outdoor unit connected to one or more indoor units. It’s ideal for additions, home offices, upstairs rooms, and spaces where ductwork is limited or comfort varies.
Ductwork Services and Airflow Improvements in Berkeley
In older Berkeley homes, ductwork can be a major source of comfort problems. Leaks, disconnected runs, and poor airflow distribution can cause cold rooms, hot rooms, and a system that runs longer than necessary.
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 heated or cooled air into the attic or crawlspace instead of delivering it into your rooms. Sealing improves comfort and reduces strain on your HVAC system.
What’s a return vent?
A return vent pulls air back into the HVAC system to be heated or cooled again. If returns are blocked or undersized, airflow suffers and the system can feel weak or uneven.
HVAC Maintenance and Tune-Ups in Berkeley
Preventive maintenance helps reduce breakdowns, improves efficiency, and extends equipment life—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 heating/cooling properly.
Indoor air quality can be affected by dust, pollen, pets, and seasonal air conditions. In older homes, duct condition and filtration choices can also impact how clean your indoor air feels.
We can help with:
Filter recommendations matched to your HVAC system
Airflow balancing to reduce stuffy rooms
Maintenance plans that keep 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.
