Here’s what happens after you replace your air conditioner in Southgate with a system that actually fits your home. Your energy bills drop—sometimes by half if you’re coming off an old unit that’s been limping along for years. You’re not calling for repairs every summer because the system is new, efficient, and sized correctly from the start.
Your house cools evenly. No more rooms that feel like saunas while others freeze. That’s what proper load calculations and quality installation get you.
And if you’re upgrading to a SEER2-compliant system in 2025, you’re also setting yourself up for rebates that can cover a serious chunk of the install cost. California’s expanded its rebate programs this year, and if your old unit qualifies, you could recoup 30 to 50 percent within the first year. That’s not a maybe—that’s how the math works when you go from an inefficient system to something modern.
All Fresh Temp has been handling AC unit replacement in Southgate and across Santa Clara County for over 40 years. We’re family-owned, and we’ve seen every kind of system, every kind of home, and every kind of summer this area throws at people.
Southgate’s Mediterranean climate means hot, dry summers and mild winters. Your AC works hard here, and when it’s time to replace it, you need someone who knows how these systems hold up in real conditions—not just what the manual says.
We don’t oversell. We don’t push unnecessary upgrades. We assess your home, calculate the load, recommend what actually fits, and install it correctly the first time.
First, we come out and assess your home. That means looking at square footage, insulation, ductwork, and how your current system was performing. We run a load calculation to figure out what size and type of unit you actually need—not what someone can sell you the fastest.
Once we know what fits, we walk you through your options. That includes SEER2 ratings, rebate eligibility, whether a heat pump makes sense for your setup, and what the install cost looks like upfront. No surprises later.
Installation day, we pull the old unit, prep the area, and install the new system using quality materials and correct techniques. That means proper refrigerant charging, sealed connections, and making sure your ductwork is ready to handle the new equipment. We test everything before we leave, and we don’t call it done until your house is cooling the way it should.
You’ll also get a walkthrough of your new system—how it works, what to expect, and when to schedule maintenance. Then we’re available if anything comes up.

When you get a home AC replacement in Southgate through All Fresh Temp, you’re getting a full system install—not just a box swap. That includes removing your old unit, disposing of it properly, and prepping your space for the new equipment.
We install systems that meet California’s 2025 SEER2 standards, which means better energy performance and compliance with updated efficiency baselines. If you’re upgrading from an older unit, that’s a noticeable difference on your electric bill—especially during summer when your AC is running daily.
You’ll also get refrigerant that’s compliant with new environmental regulations. Starting this year, systems use R-454B or R-32 instead of R-410A, which has a lower global warming potential. It’s not just about following the rules—it’s about installing equipment that won’t be obsolete in two years.
And if your ductwork needs attention, we’ll let you know. A new AC won’t perform right if it’s pushing air through leaky or undersized ducts. We handle that too, so your system works as efficiently as it’s designed to.
For a standard home AC replacement in Southgate, you’re looking at somewhere between $5,000 and $8,000 installed. That range depends on the size of your home, the SEER2 rating you choose, and whether your ductwork needs any work.
Installation costs went up about 20 to 25 percent in 2025 because of new refrigerant requirements and updated efficiency standards. But that upfront cost gets offset pretty quickly if you’re replacing an old, inefficient unit. You could save $80 to $100 a month on cooling costs, which adds up to $400 to $500 a year.
California also expanded its rebate programs this year, so depending on your system and income level, you might qualify for rebates that cover a significant portion of the install. We’ll walk you through what’s available when we assess your home.
If your AC is over 10 to 15 years old and you’re calling for repairs more than once a year, replacement usually makes more sense than another fix. Air conditioners don’t last forever—central air typically hits its limit around 15 to 20 years, and after that, you’re just buying time.
Here’s the math: if the repair cost is more than half the price of a new system, and your unit is already past its expected lifespan, you’re better off replacing it. You’ll also want to replace if your energy bills have been climbing without explanation, or if some rooms won’t cool no matter what you do.
And if your system uses R-22 refrigerant, replacement is the smarter move. That refrigerant is phased out, expensive to source, and you’ll have a hard time finding parts as your unit ages. A new system gets you modern efficiency, lower bills, and fewer headaches.
California’s minimum SEER2 rating in 2025 is 14.3, which is roughly equivalent to a SEER 15 under the old rating system. That’s your baseline, but you’ll see options that go higher—16, 18, even 20 SEER2 for premium units.
Higher SEER2 ratings mean better energy efficiency, which translates to lower monthly bills. If you’re in Southgate and your AC runs most of the summer, a higher-rated system pays for itself faster than it would in a milder climate. The upfront cost is higher, but the monthly savings add up.
We’ll help you figure out what makes sense based on how much you’re currently spending on cooling, how long you plan to stay in your home, and what rebates you qualify for. There’s no one-size-fits-all answer, but we can show you the numbers so you’re making a decision that actually fits your situation.
Most air conditioner replacements in Southgate take one full day, sometimes less if your ductwork is in good shape and we’re doing a straightforward swap. If we need to modify ductwork, upgrade electrical, or make structural changes to accommodate the new unit, it might stretch into a second day.
We’ll give you a timeline upfront after we assess your home. We’re not going to leave you without cooling in the middle of summer, so we plan installs carefully and bring everything we need to finish the job without delays.
Once the new system is in, we test it, walk you through how it works, and make sure your house is cooling properly before we leave. You’ll have cool air the same day in most cases.
Probably, yeah. California expanded its rebate programs in 2025, and there are incentives available for homeowners who upgrade to high-efficiency systems. Depending on the SEER2 rating you choose and your household income, you could qualify for rebates that cover 30 to 50 percent of your installation cost.
There are also federal tax credits available for energy-efficient HVAC systems, and those stack with state rebates in most cases. If you’re replacing an old unit with something that meets current efficiency standards, you’re likely eligible for something.
We’ll help you figure out what applies to your situation when we come out for the assessment. Rebate programs change, and the paperwork can be confusing, so we make sure you’re not leaving money on the table.
Yes, and it’s worth considering. Heat pumps provide both cooling and heating, and they’re significantly more efficient than traditional AC and furnace setups. In Southgate’s mild climate, a heat pump can reduce your energy use by up to 50 percent compared to conventional systems.
Heat pumps work by transferring heat instead of generating it, which makes them more efficient year-round. They cool your home in summer just like an AC, and in winter, they pull heat from the outside air to warm your house. Even when it’s cold outside, modern heat pumps work efficiently.
The upfront cost is a bit higher than a standard AC replacement, but the energy savings and rebate opportunities often make up the difference within a few years. If you’re replacing both your AC and your furnace, a heat pump is almost always the smarter financial move. We’ll run the numbers with you so you can see exactly what it looks like for your home.
