A heat pump that stopped heating overnight, a central air system that runs without cooling the house, a furnace that cycles on but never reaches temperature: these are the calls that come in most often from a city like Berkeley. Dense housing stock, a mix of older single-family homes and multi-unit buildings, and a growing number of properties adding cooling for the first time all feed into the same pattern. We handle the full range of heating and cooling work across Berkeley, from a single-room ductless installation to a full system replacement on a building that has been on the same equipment for years.
We cover Berkeley and the surrounding Alameda County area, working with homeowners, rental property owners, and commercial building managers on everything from urgent repair calls to planned system upgrades. Heat pumps, furnaces and mini-splits all within scope. The call starts with a conversation about what the system is doing, and the price is confirmed before anything is scheduled.
A system that goes down completely is the call that moves to the front of the schedule. No heat in the house, an air conditioner that has stopped responding, a heat pump that is running but pushing unconditioned air through the vents. These situations get scoped on the phone first, so you know what the visit covers before anyone arrives. We are available every day from 5:30 AM to 8:00 PM, and the diagnostic starts with the symptoms you describe on the call.
A property that cannot go without heating or cooling for long needs the appointment arranged around that reality. We work around tenant schedules and commercial spaces that need to stay operational. HVAC service booked around your schedule means the visit happens when it works for the property, not just when it works for us. The scope and the price are confirmed before the technician arrives, so there are no open questions on the day.
Not every call is an emergency, and not every visit needs to be. A system that is underperforming but still running, a thermostat that has started reading inconsistently, or a unit that is making a new noise are all worth a call before they become failures. Getting your comfort back is easier than you think when the problem is caught early.
Call (650) 879-8929 and we will work out what the schedule allows.
A full system replacement is a bigger decision than a repair, and the job is staged differently. Before anything is ordered, the existing equipment gets assessed: what the building actually needs in terms of capacity, whether the existing ductwork can support a new system, and whether the replacement is a straight swap or an opportunity to change how the property is conditioned. A home that has been running a gas furnace and a separate central air unit, for instance, may be a strong candidate for a single heat pump that handles both.
The property is without heating or cooling for part of the installation day, and sometimes longer if the job involves duct modifications or electrical work on the building's circuit side. We walk through the timeline on the call so you know what to expect. A written scope on installation work is provided before the job starts, covering what is being installed and what the visit includes. The price is agreed before anything is replaced.
Refrigerant leak diagnosis, evaporator coil cleaning and repair, condenser and compressor service: the cost of a repair depends on what the fault actually is and how much of the system has to be accessed to address it. A coil that is fouled from years of use costs less to clean than one that has been damaged and needs replacing. A refrigerant leak at an accessible fitting is a different job from one that requires recovering the charge and pressure-testing the whole circuit. None of that is knowable before the diagnostic, which is why the quote comes after the system has been looked at.
Where both options are genuinely on the table, we explain what each one covers and what it costs before any decision is made. An older system that needs a compressor may be worth replacing rather than repairing, depending on its age and condition. A newer system with an isolated fault is usually worth fixing. The diagnostic visit gives you the information to make that call, and the price is confirmed before any work begins.
The quote is arrived at on the call and confirmed on the visit. There is no charge discussed on this page, because the right number depends on what the system turns out to need. What you will get is a straight answer about what the visit covers and what it will cost, before anything is scheduled. One call is all it takes to get it looked at.
The evaporator coil sits inside the air handler and is responsible for pulling heat out of the air before it circulates through the building. When it gets coated in dust and debris, the system loses efficiency and the coil can eventually freeze over, stopping airflow entirely. A coil that has been neglected for several seasons often shows up as an air conditioner that runs constantly without cooling the space. Cleaning restores the heat transfer the coil was designed to handle. Where the coil is damaged rather than just dirty, repair or replacement is the next step.
A furnace that attempts to fire but does not stay lit, or one that goes through an ignition sequence and then shuts down before the burners establish a flame, is usually dealing with an ignition component or a flame sensor that has degraded. These are common faults in gas furnaces that have been in service for a number of years. The sensor reads the flame and tells the control board the burner is lit. When it cannot read cleanly, the board shuts the system down as a safety measure. Diagnosis identifies which component is responsible before anything is replaced.
Central air installation and heat pump electrification are among the most common planned jobs we handle in this area. A heat pump replaces both a heating unit and a cooling unit in a single system, which makes it a practical upgrade for properties that are moving away from gas or that need to add cooling without adding a second system. Installation involves removing the existing equipment, commissioning the new unit, and connecting it to the existing air distribution. The household electrical circuit and disconnect are handled by an electrician. We speak to the equipment and the air-side installation.
A system that runs for long stretches without reaching the thermostat set point is not always a sign that the equipment is failing. Zoning and comfort-control issues, duct leakage that bleeds conditioned air before it reaches the living space, or an air handler and blower that are moving less air than the system expects can all produce the same symptom. Refrigerant charge, coil condition, and duct integrity are all checked before a repair is quoted, because the fix depends on what is actually causing the system to fall short. If you want the longer version, it is on the heating and cooling services page.
When you call, the conversation covers the equipment type, the symptom, and roughly how old the system is if you know it. The make and model on the data plate helps, but it is not required to get a quote started. We will ask what the system is doing, when the problem started, and whether anything changed around the time it began.
From there, the scope is outlined and the rate is confirmed before anything is booked. Heating and cooling work gets explained in plain terms, and questions about what is included get straight answers on the call. No guesswork. No shortcuts. No rushed diagnosis.
We cover Berkeley and the surrounding Alameda County communities for both residential and commercial heating and cooling work. Nearby areas served include Emeryville, Albany, Kensington, El Cerrito, and Piedmont. If your property is in the area, call and we will confirm coverage when you reach out.
Property managers and landlords handling multiple units or multiple addresses are welcome to call with portfolio questions. The process is the same regardless of property type: the system gets scoped on the call, the price is confirmed, and the visit is booked.
It depends on the home. Properties with existing forced-air ductwork in reasonable condition are often candidates for central air installation, where a cooling coil and outdoor condenser are added to the existing air handler. Homes without usable ductwork are usually better served by a ductless mini-split, which requires only a small wall penetration rather than a full duct system. The visit determines which approach fits the building, and the scope is confirmed before anything is ordered.
If the properties are close together and the schedule allows, we can look at grouping them. Call and describe the locations and what each property needs. We will confirm whether the schedule supports combining them.
Yes. Minor symptoms are easier and less expensive to address than major ones. A small refrigerant leak, a capacitor that is starting to fail, or a drain line that is beginning to slow are all minor until they are not. Calling early keeps the repair in the straightforward category.
We scope each unit individually, because the condition and fault vary from one to the next even in buildings where the equipment is the same age and model. A landlord or property manager can call with a list of addresses or units and we will work through what each one needs, pricing each job on its own merits. The rate for each unit is confirmed before that unit's work is scheduled, so there are no open questions when the technician arrives.
Call as early as possible if you need to reschedule. We will look at what the schedule allows and find an alternative. The more notice you give, the easier it is to move the booking without losing the slot entirely.

We handle the full range of heating and cooling work in Berkeley and across Alameda County, from a single-room ductless install to a whole-system replacement on a commercial property. The table below covers every service we offer, who it fits best, and what is worth knowing before you call. If you have questions about a specific job, call us and we will talk through what the work involves before anything is scheduled.
| System Service | What the Service Includes | Best For | What to Keep in Mind |
|---|---|---|---|
| Full System Installation & ReplacementMost Popular |
| Homeowners whose system is aging, repeatedly failing, or unable to keep pace with the home's demands | An oversized unit short-cycles and wears out faster. An undersized one runs constantly. Correct sizing is confirmed before equipment is ordered. |
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want to catch a marginal component before it becomes an emergency call | A spring AC tune-up and a fall furnace tune-up are the two most common schedules. Either visit can surface a developing fault before the peak season puts the system under full demand. |
| Wildfire-Smoke Air Filtration (MERV-13+) |
| Bay Area households with respiratory concerns or homes that experienced smoke infiltration during fire events | Not every air handler can pull air through a denser filter without straining the blower. We check compatibility before upgrading the filtration media. |
