Hear from Our Customers
You’re not looking for someone to just patch things up. You want your HVAC system to work when you need it—cooling your house during those brutal Sunnyvale summers, heating it on the handful of cold mornings we actually get.
When your system’s running right, you’re not thinking about it. Your energy bills stay predictable. Your family’s comfortable. You’re not dealing with that one bedroom that’s always too hot or worrying whether the AC will quit the day you’re hosting people.
That’s what happens when a licensed HVAC contractor in Sunnyvale, CA actually knows what they’re doing. We’ve been doing this since 1985—40 years of service calls, system failures, and learning exactly what works in this climate. We’re not experimenting on your house.
All Fresh Temp started in 1985. Ramiro’s father founded the company, Ramiro took over in 2006, and we’re still here—family-owned, fully licensed and insured, and not going anywhere.
We’re local. We know Sunnyvale’s climate—mild most of the year, but summers that push aging air conditioners past their limits. We know the homes here, the systems people have, and the problems that come up when those systems aren’t maintained properly.
You’re busy. You don’t have time to deal with contractors who miss appointments or take days to call back. We get that, because we live here too. When you call, you’re getting someone who answers, shows up, and fixes the problem without dragging things out.
You call or fill out the form. We schedule a time that works for you—usually same day if it’s an emergency. No waiting around for a four-hour window.
Our technician shows up, looks at your system, and tells you what’s wrong. Not in technical jargon—in plain language. If it’s a simple fix, we handle it right there. If you need a part, we let you know what it costs before ordering anything.
For installations, we start with a full assessment of your home. Room sizes, insulation, ductwork, the whole picture. Then we recommend a system that actually fits your house—not the most expensive one we carry. We install it, test everything, and make sure you know how to use it.
After that, you’ve got our number. Something feels off six months later? Call us. We’ll come back and make sure it’s running right.

When you hire a local HVAC contractor in Sunnyvale, CA, you should know exactly what you’re paying for. We handle residential and commercial work—repairs, installations, maintenance, emergency calls, all of it.
Every service call includes a full diagnostic. We’re checking refrigerant levels, electrical components, airflow, ductwork—not just the obvious stuff. If your system’s inefficient, we’ll tell you why and what it’s costing you in energy bills.
Sunnyvale homeowners deal with specific challenges. Indoor air quality matters here—humidity swings, allergens, wildfire smoke some years. We address that with proper filtration and ventilation, not just cooling and heating. Energy efficiency matters too, especially with California’s utility rates. We install high-efficiency systems and make sure your existing equipment isn’t wasting power.
You’re also getting transparent pricing. We tell you the cost before we start. If something changes mid-job, we explain why and get your approval. No surprise charges when we hand you the bill.
If your system’s under 10 years old and the repair costs less than half of a new system, repair usually makes sense. You’re getting a few more good years without the upfront cost of replacement.
If it’s over 15 years old, breaking down frequently, or the repair costs are climbing, replacement is probably smarter. Older systems are less efficient—you’re paying more every month in energy costs, and parts get harder to find. A new system pays for itself over time through lower bills and fewer service calls.
We’ll be straight with you about which option makes financial sense. If a repair buys you two years but you’ll need a new system anyway, we’ll tell you that. If your system’s got plenty of life left, we’re not going to push a replacement you don’t need.
Residential installations typically run between $5,000 and $12,000, depending on the size of your home, the system you choose, and whether we’re replacing ductwork. A straightforward swap on a 1,500 square foot house with good existing ducts sits on the lower end. Larger homes or homes needing duct repairs cost more.
High-efficiency systems cost more upfront but save you money monthly. If your current energy bills are high, that efficiency pays back faster. We’ll show you the math so you can decide what fits your budget and goals.
We give you the full price before starting—labor, equipment, permits, everything. No hidden fees. And if you qualify, we’ll let you know about rebates or financing options that bring the cost down.
Twice a year is ideal—once before summer, once before winter. Even though Sunnyvale’s climate is mild, your AC works hard in summer, and your heater still needs to function when temperatures drop.
Spring maintenance catches problems before your air conditioner fails in July. We’re cleaning coils, checking refrigerant, testing electrical connections—stuff that prevents breakdowns when you actually need cooling. Fall maintenance makes sure your heater’s ready and your system’s circulating clean air as you close up the house more.
Regular maintenance extends your system’s life and keeps it efficient. Skipping it means higher energy bills, more frequent repairs, and a system that dies years earlier than it should. Most of our maintenance customers never deal with emergency breakdowns because we catch issues early.
Yes. We offer 24/7 emergency service because systems don’t just break during business hours. Your AC quits at 9 PM on a Saturday in July, your house heats up fast, and you need someone who actually answers the phone.
When you call for emergency service, you’re talking to us—not an answering service, not a voicemail. We’ll either walk you through a temporary fix or get someone out to you, usually within a few hours depending on where we are.
Emergency calls cost more than scheduled service—that’s standard across the industry. But we’re not gouging you. We’ll tell you the cost upfront, and if it’s something that can wait until morning to save you money, we’ll let you know that too.
It depends on your home’s square footage, insulation, window placement, and how much sun exposure you get. A 1,500 square foot home typically needs a 2.5 to 3-ton system, but that’s just a starting point.
Oversized systems cost more and cycle on and off too frequently, which wears them out faster and leaves your home humid. Undersized systems run constantly, never quite cooling or heating your space, and burn out early from overwork.
We do a proper load calculation before recommending a system. We’re measuring your space, checking insulation, looking at ductwork, and factoring in Sunnyvale’s climate. That’s how you get a system that actually matches your home—not a guess based on square footage alone.
Yes. We’re fully licensed and insured, which protects you if something goes wrong. If a technician gets hurt on your property or damages something during installation, our insurance covers it—you’re not liable.
Licensing means we’ve met California’s requirements for training, experience, and testing. It also means we pull proper permits for installations and follow code. That matters when you sell your home—unpermitted work can kill a sale or force you to rip out and redo the installation.
Some contractors skip licensing and insurance to undercut prices. That’s a risk you’re taking on. If they mess up your system or someone gets hurt, you’re the one dealing with the fallout. We’ve been doing this 40 years—we’re not cutting corners to save a few bucks.
