Whether you need a brand-new central air system, a high-efficiency replacement, or a ductless mini-split installation, All Heart's NATE-certified technicians deliver expert AC installation throughout Lancaster and the Antelope Valley — sized correctly, installed cleanly, and backed by 25+ years of experience.
Every Lancaster home is different. All Heart installs all major AC system types and will help you choose the right solution based on your home's size, layout, existing ductwork, and budget.
The most common whole-home cooling solution. A central AC system uses your existing ductwork to deliver consistent, even cooling to every room. Ideal for homes already equipped with ducts.
Perfect for homes without existing ductwork, room additions, garages, or any space that needs independent temperature control. Mini-splits are whisper-quiet, highly efficient, and incredibly flexible.
Is your existing AC system 12–15+ years old, requiring frequent repairs, or struggling to cool your home? Replacing it with a modern, high-efficiency system can slash your energy bills and eliminate constant repair costs.
Installing a new air conditioning system is one of the most significant investments you'll make in your home's comfort and efficiency. Get it wrong — with an undersized system, an oversized system, or improper installation — and you'll pay for it every month in high energy bills, uneven cooling, and premature system failure.
All Heart Heating, Cooling & Plumbing has been installing AC systems in Lancaster, CA since 2000. As a certified Lennox dealer, we have access to some of the industry's most efficient and reliable equipment. But more importantly, every installation starts with a professional Manual J load calculation — the industry-standard method for accurately sizing your system to your specific home, not just a square footage guess.
Our installation crews are NATE-certified, fully licensed, and experienced with every type of AC system from traditional split systems to modern inverter-driven mini-splits. We protect your home throughout the installation process, complete every job to manufacturer specification, and walk you through your new system before leaving.
We also handle all the details you shouldn't have to think about — permits, ductwork modifications, thermostat upgrades, and manufacturer warranty registration. And if budget is a concern, our flexible financing options make it easy to get the system you need now and pay over time, often with 0% interest promotions available.

Repairing an aging AC system can feel like the cheaper option — until you're paying for the third repair in two summers. Here's how to know when it's time to invest in a new system.
AC systems in Lancaster's extreme desert climate have a shorter lifespan than national averages. If your unit is approaching 15 years, proactive replacement prevents a breakdown during peak summer heat.
Use the $5,000 rule: multiply the repair cost × the unit's age. If the result exceeds $5,000, a new system is almost always the smarter financial decision.
R-22 (Freon) was discontinued in 2020 and is now extremely expensive. If your AC still uses R-22, replacement is the only long-term solution.
An old, inefficient system works harder to deliver less cooling. Upgrading to a modern 18–21+ SEER2 system can reduce your cooling costs by 30–50%.
Hot spots, uneven cooling, or an inability to keep up during the hottest days often signal that your system is undersized, oversized, or simply worn out.
If your AC has broken down twice in the past three years, you're likely spending more on repairs than a new system would cost — without the reliability of a fresh warranty.

"We had a mini-split installed for our garage workshop and All Heart was fantastic. They were quick, clean, and priced competitively. The technician took time to show me how to use the remote and set up the schedule. Absolutely love the result — the garage is finally usable year-round."

Why All HeartFrom the first call to the final walkthrough — why Lancaster homeowners choose All Heart for every installation.
AC installation in Lancaster typically ranges from $3,500–$8,500+ depending on system type, size, efficiency rating, and whether ductwork is needed. All Heart provides a free, written quote with no obligation. Call (661) 231-8118 or schedule online for your free estimate.
Proper sizing depends on square footage, insulation, ceiling height, window exposure, and local climate. In Lancaster's desert heat, homes often need more capacity than typical. All Heart performs a professional Manual J load calculation on every installation — the only accurate sizing method. Guessing leads to short-cycling and premature failure.
A standard central AC replacement typically takes 4–8 hours. New installations with ductwork modifications may take longer. Ductless mini-split installations can often be completed in 3–5 hours. All Heart's crews work efficiently to get your home cool as quickly as possible.
Central AC is ideal for ducted homes and whole-home cooling. Ductless mini-splits are better for homes without ducts, room additions, garages, or spaces needing independent temperature control. Mini-splits are also typically more efficient. All Heart installs both and will give you an honest recommendation based on your home and budget.
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently your AC converts electricity to cooling. California requires a minimum of 15 SEER2 for new systems. In Lancaster's extreme climate where AC runs 6+ months a year, upgrading to 18–21+ SEER2 can reduce cooling costs by 30–50% and typically pays for itself within a few years.
