A failing AC in Daly City is more than an inconvenience -- during peak summer heat, it's a real safety concern, especially for older family members and young children. Our Daly City technicians diagnose the root cause quickly: whether it's a refrigerant leak, a failed capacitor, a faulty compressor, or a clogged drain line, we address it with the right repair the first time.

When your heat goes out in Daly City in the middle of winter, every hour without it matters. All Year HVAC provides emergency heating repair around the clock, covering furnaces, heat pumps, and boilers across all major brands. Our technicians inspect every critical component -- heat exchanger, ignition system, gas valve, flue, and safety controls -- and give you a clear picture of what's needed before any repair begins. We don't recommend replacements unless the numbers genuinely support it; our job is to keep your system running as long as it makes financial sense to do so.

When the time comes for a new system in your Daly City home or business, the quality of the installation matters just as much as the equipment itself. An undersized or oversized unit installed poorly will underperform and fail early regardless of brand. Our installation process starts with a proper load calculation for your specific building, followed by equipment selection that balances efficiency, budget, and long-term performance. We handle all ductwork assessment, permitting if required, and post-installation testing to confirm the system is operating to spec before we leave your property.

The single best thing Daly City homeowners can do for their HVAC systems is schedule regular maintenance before problems develop. Our annual maintenance plans cover bi-annual tune-ups, priority emergency scheduling, and discounts on parts and labor when repairs are needed. During each visit, our technicians perform a comprehensive inspection of every major component -- cleaning, lubricating, measuring, and calibrating to keep your system running at peak efficiency. Customers on our maintenance plans consistently see lower energy costs and avoid the unexpected repair bills that sideline unprepared homeowners every season.

The air quality inside your Daly City home has a direct impact on the health and comfort of everyone who lives there. Dust, allergens, mold spores, and humidity imbalances are common problems that your HVAC system can either control or contribute to depending on how it's maintained and configured. All Year HVAC provides air quality assessments, high-efficiency filtration upgrades, whole-home humidifiers and dehumidifiers, and UV air purification systems. If anyone in your household deals with allergies, asthma, or respiratory sensitivities, an air quality upgrade can make a meaningful difference in day-to-day wellbeing.

Leaky or dirty ductwork can account for significant energy loss and poor air distribution throughout your Daly City home. If certain rooms are consistently harder to heat or cool than others, or if you notice dust buildup accelerating near your vents, your ducts may need attention. Our duct inspection and sealing service identifies leaks and weak connections that force your HVAC system to work harder than necessary. Duct cleaning removes accumulated debris, allergens, and buildup that circulate through your living spaces with every heating or cooling cycle. Most Daly City homeowners are surprised at how much of a difference properly maintained ductwork makes to system performance and air quality.
Learn About Duct ServicesLet's be straightforward about something: in most areas, there's no shortage of HVAC companies willing to take your call. The real question isn't whether you can find someone to show up -- it's whether the company you call will actually solve your problem, charge you a fair price, and treat your home with respect. That's where All Year HVAC earns its reputation in Daly City, CA, and across the communities we serve.
All Year HVAC was built on a simple philosophy: HVAC service doesn't have to be a frustrating experience. Too many homeowners in Daly City have dealt with contractors who give vague estimates over the phone, arrive late with no explanation, diagnose problems incorrectly, and then present a bill that doesn't match what was discussed. We've heard these stories from our own customers before they found us, and we set out to build a company that operates completely differently.
Every technician who serves Daly City customers has been through a thorough vetting and training process before they ever step foot in a customer's home. We check certifications, confirm state licensing requirements are met, run background checks, and conduct ongoing skills evaluations to make sure our team stays current as HVAC technology evolves. We carry EPA 608 certification for refrigerant handling across our team, and our installation technicians are trained on the load calculation and commissioning standards that separate a properly sized system from one that will underperform from day one.
When you call us in Daly City, you'll speak to a real person -- not a voicemail box, not an automated system that will "call you back within 24 hours." Our dispatchers are trained to gather the right information about your situation so they can route the most appropriate technician to your location quickly. If your problem is an emergency -- no heat in January, no AC during a heat advisory -- we treat it accordingly. If it's a scheduled maintenance visit, we confirm the appointment clearly and show up when we say we will.
We've made a commitment to transparent pricing that we don't compromise on. Before a single repair is made or part is replaced, you'll have a written quote in front of you. That quote covers labor, parts, and any applicable fees -- there's nothing left out to surprise you on the invoice. We'd rather lose a job than win it by hiding charges. The customers who call All Year HVAC in Daly City a second time, and a third, and who refer their neighbors to us -- those relationships are built on trust, and trust starts with being honest about what something costs.
We're also deeply invested in the long-term performance of the systems we work on. A repair that holds for two months and then fails again isn't a repair -- it's a delay. We diagnose problems at their source, not just at the symptom. When we replace a part, we inspect the surrounding components to make sure the root cause isn't something else that will cause the same failure again in six weeks. When we install a new system in a Daly City home, we test it fully before leaving and schedule a follow-up to confirm it's performing as expected after the first full operating cycle.
Local service matters to us. The Daly City community is not an abstraction -- it's made up of real families dealing with real comfort problems, often at the worst possible times of year. We think about that when we respond to calls, when we train our technicians, and when we make decisions about how we operate. We want to be the HVAC company that Daly City homeowners and business owners can count on, not just the first available number on a search results page.

Real feedback from homeowners in Daly City and the surrounding area who've worked with All Year HVAC.
"I wasn't sure who to call when our AC died on a Sunday afternoon -- temps outside were brutal. Called All Year HVAC and was genuinely surprised when someone answered immediately. The technician arrived within a few hours, diagnosed a failed capacitor, had the part on his truck, and had us back up and running before it got dark. The price was fair and matched exactly what he told us upfront. Can't ask for more than that."
"We needed a full system replacement after our old unit finally gave out. Three companies gave us quotes -- All Year HVAC came in with a clear, detailed breakdown that was easy to understand, the right equipment for our home size, and a competitive price. They completed the install in one day, cleaned up the work area completely, and walked us through the new system thoroughly. Two months in, the house has never been more comfortable and our energy bill is noticeably lower."
"Signed up for a maintenance plan because I was tired of scrambling every time something went wrong. The technician who came for the fall tune-up was thorough and explained everything in a way that actually made sense. He found a minor issue with the igniter and fixed it on the spot -- said if left unchecked it would have failed mid-winter. That alone paid for the whole plan. I'll be renewing without hesitation."
