When a system stops working in Pacifica, the call we get is almost always the same: the house is too cold, the house is too hot, or something is running but not doing anything useful. We handle the full range of heating and cooling work for homes and rental properties in this city, from a single-room ductless install to a complete system replacement. Questions about the equipment get answered before anything is booked.
We work with homeowners dealing with a system that has finally given out, and with landlords managing a repair at a property where a tenant is waiting. Whether the call is for a furnace that won't fire, an air conditioner pushing warm air, or a heat pump that has stopped responding to the thermostat, the first step is the same: scope the problem on the phone, confirm the price, and get someone out.
Call (650) 879-8929 to get started. We are available every day from 5:30 AM to 8:00 PM.
Uneven temperatures are one of the most common complaints we hear, and the answer is rarely the one a homeowner expects. A room that never cools down in summer or never warms up in winter usually points to something upstream of the room itself.
Older homes in this city often have duct systems that were sized for a smaller footprint. When a room was added or a layout changed, the ducting sometimes followed and sometimes did not. A register that delivers half the airflow it should, a duct run with a sharp bend that kills pressure, or a section that has pulled apart in a crawl space can all produce the same symptom: one room that the system simply cannot reach.
A system that is oversized for the space it conditions short-cycles. It hits the thermostat set point in the main area, shuts off, and never finishes moving air to the far end of the house. An undersized system runs constantly and still falls short. Neither is a duct problem. Both feel like one. The diagnostic visit separates them.
Getting an appointment arranged is straightforward. Call, describe what the system is doing, and we confirm the scope and the price before anything is booked. HVAC service booked around your schedule means we work around the times that suit the property, whether that is early morning before a business opens or a window that works around a tenant's schedule.
When there is no heat or no cooling at all, the call is treated accordingly. A system that has gone down entirely gets scoped on the phone the same way a routine repair does, and the visit is arranged as quickly as the schedule allows. For properties where a tenant or a business has to stay operational, that context is part of the conversation when the appointment is set. We will look at the system and tell you what it needs.
From aging systems to brand-new installs, the job type shapes how the visit goes. Below are the situations that lead to each kind of work we handle.
An air conditioner or heat pump that runs for long stretches without reaching temperature, or one that develops ice on the lines, is often losing refrigerant. The leak has to be found before anything is added back, because topping up a system that is still leaking solves nothing. We locate the fault, repair it, and restore the charge to the correct level for the equipment.
A hydronic heating system circulates hot water through the building to heat the living space. When a zone stops heating, a pump fails, or pressure drops without explanation, the system needs to be diagnosed the same way any other heating equipment does. We service boilers and hydronic systems for space heating, and the work stays on the heating side of the equipment.
When a system has reached the point where repair costs are stacking up against a unit that is already well past its useful life, replacement is usually the clearer path. A full replacement covers removing the old equipment, installing the new system, and testing it through a complete cycle before the visit ends. A written scope on installation work is provided before anything starts, so the job is defined before anyone picks up a tool.
Leaking ducts bleed conditioned air into attic space or crawl spaces before it reaches the room it was meant for. The result is higher energy use and a system that runs longer than it should to hit a set point it can never quite reach. Duct sealing addresses the loss directly. Where ducts have pulled apart or were never properly connected, duct repair brings the distribution system back to what the equipment was designed to work with.
Indoor air quality is shaped by more than temperature. A home that is too dry in winter stresses woodwork and makes the air feel colder than it is. A space that holds too much moisture encourages mold and makes cooling less effective. Whole-home humidifier and dehumidifier systems connect to the existing HVAC equipment and manage humidity automatically. The right choice depends on the climate the building sits in and how the existing system is set up.
Pacifica has a housing stock that skews older, and older properties come with their own set of complications. A system that was installed decades ago may use refrigerants that are no longer manufactured, or rely on components that take time to source. That is not a reason to avoid the repair, but it is a reason to scope the job carefully before committing to one path.
Ductwork is the other place where age shows up. A duct system that was designed for a smaller home, or that was extended informally when a room was added, rarely performs the way the equipment expects it to. The blower pushes against restrictions it was never designed for, and the result is uneven airflow across the property. Assessing the duct system alongside the equipment is part of how we approach older homes.
Additions are their own category. A room built onto the back of a house, a converted garage, or a finished basement often sits at the end of a duct run that was never meant to carry the load. A mini-split or ductless system handles these spaces cleanly, without touching the existing distribution system at all. One call is all it takes to get it looked at.
Pricing on a heating or cooling job depends on what the fault turns out to be, where it sits in the system, and whether a repair or a replacement is the right answer once the equipment has been assessed. None of those questions can be answered before someone has looked at the system, which is why the price is confirmed after the diagnostic rather than before it.
What does not change is how the conversation goes. When you call, the situation gets discussed, the scope is outlined, and the rate is confirmed before anything is scheduled. On installation work, the written scope is the reference point for the invoice. On a repair call, the repair is agreed before work begins. Ask what is covered and you get a straight answer.

If your property is nearby and you are not sure whether it falls within our coverage, call and we will confirm when you reach out. The area served is the whole stretch of communities along this part of the county, residential and commercial alike.
It is one of the more common installs we handle in homes like these. A ductless system does not require existing ductwork, which makes it a practical fit for older construction where running new ducts through finished walls and ceilings would be disruptive. The visit covers the layout of the space and confirms what the installation involves before anything is quoted.
Salt air and coastal moisture can accelerate corrosion on outdoor condenser coils and electrical connections over time. A maintenance visit that includes cleaning the coil surfaces and checking the condition of exposed components is worth doing on a regular schedule for equipment that sits outside in this environment. The technician will note anything that looks like it is getting ahead of itself and walk you through the options.
A property with no heat is one of the calls we respond to as quickly as the schedule allows. When you call, tell us the property has no heat and describe the equipment and the symptom. We will scope the situation on the phone and tell you what the schedule can support.
Yes. A fault that appears after the system has been running for a period points toward components that fail under heat or load rather than at startup. Knowing that narrows the diagnostic focus. Tell us on the call whether the symptom appears immediately or only after the system has been running, because that detail changes where we look first.
Yes, and the shoulder seasons are the best time to book. Scheduling a furnace tune-up in early fall or an AC tune-up in early spring means the system is looked at before it is under full demand. Faults found then are easier to address than faults found when the system fails during a heat event or a cold snap.
The clearest answer to that question comes after someone has actually looked at the equipment. A system that seems beyond saving sometimes has an isolated fault. One that seems repairable sometimes has enough accumulated wear that a replacement is the better investment. Neither answer is available until the diagnostic happens.
We are available every day from 5:30 AM to 8:00 PM.

| System Service | What the Service Includes | Best For | What to Keep in Mind |
|---|---|---|---|
| AC Repair & Service |
| Homeowners or property managers with a system that has stopped cooling or is underperforming | A system that runs but does not cool often has a refrigerant, coil, or compressor issue rather than a simple part failure. Diagnosis comes before any repair quote. |
| Heat Pump Repair & Service |
| Homes in Pacifica already running a heat pump that is not reaching temperature or switching modes incorrectly | Pacifica's mild winters are well suited to heat pump operation. A system that blows cool air in heating mode often has a reversing valve or refrigerant fault. |
| 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. |
