Our Air Conditioning Installation Process in Ontario, CA

The Installation Process: 6 Steps to Comfort
- In-Home Evaluation and Free Estimate
First things first: we visit your home and do a full evaluation. That includes inspecting your current heating and cooling systems, looking at things like your existing ductwork, the layout of your space, and how well your current AC unit is performing (or not performing!). We listen to your needs—whether you’re chasing better energy efficiency, quieter operation, or smart thermostat compatibility. Based on all this, we offer a free estimate with options that fit your budget, lifestyle, and square footage. No pressure, no upsell—just helpful, honest advice from our seasoned HVAC experts.
- Choosing the Right AC System
We’ll help you choose the perfect air conditioning system for your home. There are many options out there, and we break them down so they’re easy to understand. Whether it’s a powerful central AC, a quiet and compact ductless mini-split, or an energy-efficient heat pump, we recommend what best suits your home layout, existing HVAC systems, and comfort needs. We also consider extras like air filter upgrades, temperature zoning, and smart controls that keep you cool and in control.
- Scheduling Your Installation
Once you’ve picked out your new device, we coordinate an installation day that works around your schedule. We aim for minimal disruption to your daily life. Our professional technicians show up on time, in uniform, ready to go. We prep your home with floor coverings and other protective measures, respecting your space like it’s our own. You’ll know exactly what to expect and when we’ll be done.
- Removing the Old System
Next, it’s time to say goodbye to that old air conditioner. We carefully disconnect and remove the outdated AC unit, making sure to safely handle any old refrigerant and parts. If your system has an evaporator coil or air handler that needs replacing, we take care of that too. We dispose of all components responsibly and in accordance with environmental regulations.
- Installing the New AC Unit
Now comes the exciting part. We install your brand-new air conditioning system, making sure every connection is tight, every wire is safely in place, and the system is optimized for energy efficiency and performance. Our HVAC services include a full range of testing to ensure your cooling systems are working properly and delivering the desired temperature in every room. We also calibrate your thermostat and show you how to use all the new features.
- Final Walkthrough & Maintenance Tips
Before we leave, we do a thorough walkthrough with you. We explain how the system works, review any warranties, and provide tips on maintenance service to keep things running smoothly. From air duct cleaning to scheduling your first tune-up, we’re here to support your comfort long-term. We don’t just install and leave—we build relationships based on trust, quality service, and real results.
6 Signs You Need AC Replacement
1. Your AC is old – On average, if your AC is over 10 years old it is time to start considering replacement. Older units are more vulnerable to breakdowns, lack of efficiency, and reliability. Don’t wait till the hottest parts of the year to break down when you mostly need it.
2. Poor performance – If your AC isn’t cooling like it used to or perhaps not regulating humidity properly, then it could be time for a new AC replacement.
3. Loud noises – Not all loud sounds coming from your unit are an indication that you need new AC installation. If something is rattling or loose we can fix that no problem but if you hear rumbling or grinding then you could have bigger problems.
4. It requires R22 Freon – While it’s not illegal to use the banned coolant, it will become cost prohibitive as the production has ceased. Consult our Ontario AC replacement experts because that’s going to save you more money in the long run than relying on this banned coolant.
5. Repair after repair – After enough repair calls, another one becomes expensive and inconsequential. Also, be wary of expensive repairs on older units as a new AC installation is on the horizon anyhow.
6. Electrical bills on the rise – As HVAC units age they’ll become less efficient over time. What this means is your indoor air temperature will be fine but it will cost more money to do that each month. Consult our Ontario AC replacement experts if you want to get an energy efficient unit.
How Long Does the Installation Process Take?
A typical AC installation takes one full day. However, this can vary depending on your home’s layout, whether we’re doing an AC replacement or a fresh install, and if ductwork needs modification. We work quickly but never cut corners. Our team keeps you informed at every step to ensure the job is done right, not rushed.
Does All Pro Also Install Ductless Mini-Splits?
Yes, we do! Ductless systems, also known as mini-split AC systems, are an excellent choice for homes without existing ductwork, room additions, or multi-zone comfort needs. These systems are sleek, quiet, and incredibly efficient. We also install mini-split heat pumps for year-round heating and cooling. They’re ideal for customizing temperatures in different zones and can save you a bundle on your energy bills. If you’re interested in a modern, flexible option that doesn’t require extensive construction, a ductless setup could be perfect for you.
Does All Pro Also Install Air Ducts?
Absolutely! We provide expert air duct installation along with our HVAC services. Whether your current ducts are leaky, too small, or non-existent, our professional technicians can design and install a duct system that improves airflow, boosts energy efficiency, and helps your air conditioning units perform better. We use high-quality materials and precise layouts tailored to your home’s design. Good ductwork also helps with air filter efficiency and improves indoor air quality. If you’re building new or upgrading your heating and cooling, don’t overlook your ducts—they’re the backbone of your HVAC system!

How Do I Choose My Air Conditioner?
We get it—choosing the right air conditioner can feel overwhelming. But don’t worry, we’ll help you figure it out.
Here’s what we consider:
- Home Size & Layout: Bigger homes need more powerful systems. Open floor plans may benefit from zoning or multi-head ductless systems.
- Existing Ductwork: If you don’t have ducts, a mini-split might be your best option.
- Your Energy Goals: Want to slash those energy bills? We’ll recommend high-efficiency models that work with your goals.
- Comfort Preferences: Want quiet? Looking for smart features? Prefer stronger airflow? We match you with features that fit your lifestyle.
- Budget: We’ll offer tiered options—good, better, best—so you can decide what’s right without pressure.
No matter your needs, our team of HVAC experts is here to guide you through every step. We’re family-owned, rooted in the Ontario community, and dedicated to giving you the best quality service around. Whether it’s a total replacement, repair, or first-time installation, we treat your home like it’s our own.
Factors That Can Affect a New Air Conditioner Installation Cost
When it comes to budgeting for your new air conditioning installation, it helps to understand what influences the total cost. It’s not just the AC unit you’re paying for—it’s also the labor, materials, and the unique setup of your home.
Type and Size of the System: Choosing between a central AC, heat pump, or ductless system can significantly affect your bottom line. Bigger homes need more powerful systems, and size matters when it comes to cooling efficiency. Oversized units can short-cycle and waste energy; undersized ones will struggle to keep up. We always help you size your system correctly.
Ductwork Needs: If your home doesn’t have ducts or they need to be replaced, that adds cost. But it’s worth it for better performance and air quality. We inspect ducts for weak airflow, leaks, or poor design before moving forward. Sometimes a full replacement service is needed, especially in older homes.
Energy Efficiency Ratings: High-efficiency units with better SEER (Seasonal Energy Efficiency Ratio) ratings cost more upfront, but they offer big savings over time on energy bills. If you’re planning to stay in your home long-term, a more efficient unit is a smart investment.
Smart Features and Add-ons: Features like smart thermostats, zoning systems, enhanced filtration, or dehumidifiers can increase costs but improve comfort and control. Some of these upgrades can also prevent further damage to your system by maintaining better operating conditions.
Complexity of the Installation: Homes with limited access to certain areas, electrical upgrades, or retrofitting requirements can increase installation time and labor. Our extensive experience helps us anticipate these challenges and provide accurate upfront estimates.
In the end, we offer a free estimate and walk you through every detail, so you’re never surprised by the final bill.
Will a New Air Conditioner Help Me Save on the Energy Bill?
Yes, it absolutely can. If you’ve been dealing with an old air conditioner that’s struggling to keep up, it’s probably using a lot more electricity than it should. A new, properly installed, energy-efficient AC unit can drastically lower your monthly energy bills by cooling more effectively and running less often. Features like variable-speed motors, better insulation, and smarter thermostats all contribute to greater savings. Plus, our maintenance service helps you keep that efficiency high over time.
