Your System Works When You Need It Most

You’re not calling because everything’s fine. Something broke, the air quality’s terrible, or your energy bills are out of control. Maybe it’s all three.

Here’s what changes when your HVAC system actually works: your indoor air stays clean during wildfire season, your home stays comfortable when temperatures swing from chilly mornings to hot afternoons, and your utility bills drop because the system isn’t fighting itself. You stop worrying about whether the AC will quit on the hottest day or if smoke is getting inside.

As a residential HVAC contractor in Palo Alto, CA who knows the local climate, we understand that your system needs to handle more than just heating and cooling. It needs to filter out particulates during fire season, meet the city’s strict energy codes, and run efficiently enough that you’re not paying PG&E more than your mortgage. That’s the baseline.

We've Been Doing This Here for Years

All Fresh Temp is a family-owned company based right here in the Bay Area. We’re not a national franchise with a call center in another state. When you call, you’re talking to someone who knows Palo Alto’s building codes, understands the wildfire smoke problem, and has worked on hundreds of systems in homes just like yours.

We handle everything from emergency repairs to full heat pump installations. Our techs are licensed, our work is permitted, and we show up when we say we will. If your system needs a repair, we’ll tell you. If it needs a replacement, we’ll explain why and walk you through rebate options that can cover up to half the cost.

You’re dealing with enough. We keep it straightforward.

Here's What Happens When You Call

First, we listen. You tell us what’s going on—no cooling, weird noises, high bills, smoke smell, whatever it is. We ask a few questions to get a clear picture before we even leave the shop.

Then we come out and diagnose the problem. We’re not trying to upsell you on a new system if a $200 part fixes it. But if your 20-year-old unit is on its last leg and violates the new efficiency standards, we’ll walk you through what replacement looks like, what it costs, and what rebates you qualify for. Most Palo Alto residents can stack federal, state, and utility incentives to cut installation costs in half.

If it’s an install, we pull the permit, coordinate inspections, and make sure everything meets city code. If it’s a repair, we fix it with quality parts and explain what we did and why. Either way, you’re not left guessing what happened or what comes next.

Commercial HVAC Contractor Palo Alto, CA

What You Actually Get From Us

We install high-efficiency heat pumps that meet Palo Alto’s new AC2HP replacement policy. If your air conditioner dies, the city now encourages heat pump upgrades to hit their 2030 carbon neutrality goals. We handle the whole process—equipment selection, rebate paperwork, permits, and installation.

Indoor air quality is a big deal here. We install MERV 13 filtration systems and standalone HEPA units designed to handle wildfire smoke. When the AQI spikes, your indoor air doesn’t have to. We also integrate smart thermostats that learn your schedule and adjust automatically, so you’re not heating or cooling an empty house.

For commercial properties, we work on larger systems that need to keep employees and customers comfortable without blowing the operating budget. We handle routine maintenance, emergency repairs, and full replacements. Palo Alto’s business owners deal with the same air quality and efficiency challenges as homeowners—just on a bigger scale.

Emergency service is available when your system fails at the worst possible time. We dispatch fast, often same-day, because a broken AC in July or a dead furnace in January isn’t something you can wait three days to fix.

Do I need a permit to replace my HVAC system in Palo Alto?

Yes. Most HVAC installations and major replacements in Palo Alto require a city permit to meet safety and energy requirements. The city has strict building codes, especially around energy efficiency and emissions, and they want to make sure new systems comply.

Your HVAC installation contractor in Palo Alto, CA should handle the permit process for you. We pull permits, coordinate inspections, and make sure everything passes the first time. If a contractor tells you a permit isn’t necessary, that’s a red flag. Unpermitted work can cause problems when you sell your home or file an insurance claim.

The permit process adds a few days to the timeline, but it protects you. It ensures the system is installed correctly, meets code, and won’t cause issues down the road.

A lot. Bay Area residents can stack multiple rebate programs to cover 40-50% of installation costs. Here’s how it breaks down: federal tax credits cover up to 30% of the cost, California’s TECH Clean California program offers up to $3,000, the Bay Area Air Quality Management District provides $500-$1,500, and PG&E offers utility rebates between $500-$2,000.

If you’re income-eligible, some programs increase. For example, Palo Alto’s heat pump HVAC rebate offers up to $5,000 for qualifying households. The exact amount depends on your system type, household income, and which programs you qualify for.

We help you navigate the paperwork. Rebate applications can be confusing, and missing a step can delay your payment or disqualify you entirely. We’ll walk you through what’s available, what you’re eligible for, and how to apply correctly.

You need a system with high-efficiency filtration—MERV 13 or higher for whole-house protection, or a standalone HEPA unit for targeted coverage. Standard filters don’t catch the fine particulate matter (PM2.5) that makes wildfire smoke dangerous. During fire season, indoor air quality can match or exceed outdoor pollution levels without proper filtration.

A whole-house MERV 13 filter integrates with your existing HVAC system and filters air every time the system runs. It catches smoke, pollen, and other particulates before they circulate through your home. HEPA units are standalone devices that provide even finer filtration in specific rooms—bedrooms, home offices, wherever you spend the most time.

As your licensed HVAC contractor in Palo Alto, CA, we assess your current system and recommend the right filtration setup based on your home size, ductwork, and air quality concerns. Some older systems can’t handle high-efficiency filters without modifications, so it’s worth getting a professional evaluation before you buy anything.

Most residential installations take one to three days, depending on the complexity. A straightforward heat pump replacement where the ductwork is in good shape usually takes a full day. If we’re adding new ductwork, upgrading electrical panels, or installing a more complex system, it can take two to three days.

The permit and inspection process adds time on the front and back end. We submit permit applications as soon as you approve the project, and the city typically processes them within a few days. After installation, a city inspector needs to sign off before the system is officially approved. We schedule that inspection and make sure everything passes.

If you need emergency service and your system is completely down, we can often get a temporary solution running the same day while we line up the full replacement. Nobody should go without heating or cooling for days, especially during extreme weather.

A heat pump heats and cools. A traditional AC only cools. That’s the short answer. Heat pumps move heat instead of generating it, which makes them three to four times more efficient than conventional heaters and air conditioners. In winter, they pull heat from outside air and move it inside. In summer, they reverse the process and pull heat out of your home.

For Palo Alto’s mild winters and hot summers, heat pumps are ideal. You get year-round comfort from one system, and your energy bills drop because the system isn’t working as hard. Palo Alto’s new AC2HP policy encourages heat pump upgrades when air conditioners fail, and the rebates make them more affordable than ever.

The upfront cost is higher than a standard AC, but the efficiency savings and rebates close that gap fast. Most homeowners break even within a few years, and after that, it’s all savings. Plus, you’re meeting the city’s carbon neutrality goals and future-proofing your home against stricter regulations down the road.

Yes. We work on commercial systems for offices, retail spaces, restaurants, and other businesses throughout Palo Alto. Commercial HVAC is more complex than residential—larger equipment, more zones, higher usage demands—but the fundamentals are the same. Your system needs to keep people comfortable, maintain good air quality, and run efficiently.

We handle routine maintenance, emergency repairs, and full system replacements. Regular maintenance prevents expensive breakdowns and keeps your system running efficiently, which matters when you’re paying commercial utility rates. If something does break, we respond fast because downtime costs you money and frustrates customers or employees.

As a commercial HVAC contractor in Palo Alto, CA, we help businesses navigate the same air quality and efficiency challenges that homeowners face. Wildfire smoke affects your indoor environment, energy codes apply to commercial buildings, and rebates are available for qualifying upgrades. We’ll assess your current system, identify problems, and recommend solutions that make sense for your budget and operations.
