Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
When your AC hums but won't cool, blows warm air, or keeps tripping the breaker, the fix is usually a single worn component. We test the system, find it, and replace it, often the same day. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.
If something seems off with your comfort system, it usually comes down to one of these. Here are the problems we get called about most across Berkeley, and how we put a stop to each.
A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.
AC repairIf the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.
Furnace repairEnergy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementDust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationA house at 90 degrees is an every-hour problem, so we treat it like one. Same-day appointments across Berkeley, with evenings and weekends available.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
We treat your budget like our own: fix what's fixable, replace what isn't, and size every new system to your home instead of the biggest thing on the truck.
We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.
For over 12 years, Berkeley HVAC has been a leading provider for HVAC service in this part of CA. Our hometown technicians understand the unique challenges that affect systems in this area, from the age of local housing stock and its ductwork quirks to the code requirements local inspectors actually check.
Knowing Berkeley is half the job. We've learned which neighborhoods run undersized ducts, how the local climate loads systems season to season, and what inspectors here look for on permits, and we put that knowledge to work on every job so it's done right the first time.
Talk to someone who actually knows heating and cooling. Honest, no-pressure pricing over the phone.
We follow a proven, systematic approach to diagnose the problem, fix it right, and keep your home comfortable.
Call (510) 201-4758 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
A technician evaluates the unit on-site, confirms exactly what's wrong, and lays out a plan and a price before any work begins.
Whether it's a ten-minute capacitor swap or a full system changeout, the work is done carefully, tested thoroughly, and left cleaner than we found it.
The job isn't done until conditioned air is flowing and verified. We'll also show you the simple habits, and offer the maintenance schedule, that add years to the system's life.

Acting quickly keeps a small failure from becoming a big one. Here's exactly what happens when you call Berkeley HVAC for emergency HVAC service.
Our team answers your call promptly, gathers key details, cooling or heating, running or dead, any error codes on the thermostat, and gets you on the schedule, often same-day. We'll walk you through the quick checks worth trying first in the meantime.
Our experienced technician arrives at your property with diagnostic tools and the common replacement parts ready to get started right away. Capacitors, contactors, igniters, and motors are already on board.
This is where the problem actually gets solved. We repair what's repairable immediately, and when replacement is the honest answer, we handle removal, disposal, and a code-compliant install without drama.
Lasting comfort is the whole point. We verify the repair, note the system's age and condition, and offer a simple seasonal plan that keeps efficiency up, breakdowns down, and miserable nights off your calendar.
"Another company quoted us a full system replacement. Berkeley HVAC found a bad blower motor in twenty minutes and repaired it on the spot. The tech said the rest of the system had years left in it. You remember honesty like that."
"From the estimate to the final walkthrough, the whole install was smooth and organized. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote to the penny. The new system is so quiet we barely notice it running. Highly recommend."
"Half our house was always five degrees warmer than the thermostat said. The tech found crushed flex duct and a dampener stuck half-closed, then set up a new smart thermostat and actually taught us how to use it. The whole house is finally even."
We do more than patch the symptom. We make sure the job is done right. Every visit is backed by our experience, honest recommendations, and thorough work you can count on.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
We match every replacement to an actual load calculation rather than defaulting to whatever's on the truck. Installations get done to code: correct gas and electrical work, balanced airflow, and full commissioning. Most installs are completed in a single day with minimal disruption.
Our team focuses on keeping systems alive with simple, scheduled care. If you want to avoid the emergency replacement, our spring and fall maintenance visits clean coils, verify the charge, and test every safety control. No surprises, no hidden fees. This approach is one reason we maintain a 4.8-star rating across hundreds of reviews.
