Air Conditioner Replacement
If your old AC unit struggles to keep up with the California heat, our team offers professional air conditioning replacement designed for comfort and long-term savings. Serving Pasadena, Ontario, Riverside, and surrounding cities, Daniel’s installs high-efficiency cooling systems that lower utility bills, reduce maintenance costs, and keep your home cool for years to come.
Time for an Upgrade?
If your current air conditioner:
- Requires frequent or high-cost repairs
- Uses outdated R-22 refrigerant
- Fails to cool evenly or runs excessively
- Is over 12–15 years old
- …it’s likely time to consider a replacement. Daniels HVAC delivers data-driven system evaluations to help you decide whether a repair or replacement will yield the best long-term return.
The Technical Side of AC Replacement
Air conditioning replacement isn’t just swapping equipment—it’s an engineering process. The performance of a new system depends on matching
capacity, refrigerant line sizing, and airflow design to your home’s load requirements.
Daniels technicians follow
ACCA Manual J, D, and S guidelines to ensure every system is properly designed and commissioned for your home’s unique conditions.
We verify:
- Manual J Load Calculations: Thermal loads from walls, windows, insulation, and occupancy.
- Manual D Duct Sizing: Ensures static pressure ≤0.8 in. w.c. and proper CFM per register.
- Manual S Equipment Selection: Matches capacity and efficiency ratings (SEER2/EER2) to load data.
This process eliminates short-cycling, uneven cooling, and wasted energy.
Our AC Replacement Process
System Assessment & Sizing
- Perform a full heat-gain analysis using Manual J software.
- Inspect existing ductwork for leakage, insulation, and design limits.
- Measure static pressure and airflow to verify duct compatibility.
Equipment Recommendation
- Present SEER2-rated systems from trusted manufacturers like Trane, Goodman, and Lennox.
- Compare single-stage, two-stage, and variable-speed options.
- Discuss refrigerant type (R-410A vs R-32 systems) and potential energy rebates.
Professional Installation
- Recover and dispose of old refrigerant per EPA Section 608 standards.
- Replace line sets when required and pressure-test with nitrogen to 300 psi.
- Pull deep vacuum to <500 microns before charging to manufacturer specifications.
- Verify thermostat communication, airflow (CFM/ton), and condensate drainage.
Commissioning & Verification
- Measure superheat/subcool values to ±3°F accuracy.
- Confirm amp draw, voltage balance, and pressure stability.
- Provide a final commissioning report documenting operating data and warranty registration.
Efficiency and Performance Benefits
A properly installed high-efficiency air conditioner can deliver:
- 30–40% lower energy usage versus older systems
- Quieter operation through variable-speed fan and compressor technology
- Precise humidity control via staged or inverter modulation
- Improved indoor air quality when paired with advanced filtration or purification systems
By meeting AHRI and ENERGY STAR standards, Daniels installations ensure your system performs at or above its rated SEER2 level for the lifetime of the equipment.

Frequently Asked Questions
How much does AC repair cost in California?
AC repair costs vary depending on the issue, the age of your system, and the parts required. Minor fixes like replacing a capacitor or unclogging a drain line are often inexpensive and can be done the same day. Larger repairs—like replacing a blower motor or refrigerant coil—require more labor and parts, which raises the cost.
At Daniel’s, we always provide upfront, transparent pricing before work begins. That means no surprise add-ons or hidden fees after the fact. On average, most homeowners in California can expect to spend between $150–$600 for common AC repairs, but the exact number depends on your system and the complexity of the issue.
We also understand that breakdowns aren’t always planned. That’s why we offer financing options and same-day service so you don’t have to choose between comfort and cost.
Why is my air conditioner blowing warm air?
If your AC is blowing warm instead of cool air, several issues could be at play. The most common is low refrigerant caused by a leak, which prevents the system from cooling properly. Another possibility is a dirty air filter or clogged evaporator coil, which restricts airflow and reduces performance.
Electrical issues can also play a role. If the outdoor condenser isn’t running, the fan indoors may still circulate air, but it won’t be cooled. Faulty thermostats or compressor problems can also cause warm air issues.
Because there are so many potential causes, it’s important to have a professional technician perform a diagnostic. At Daniel’s, we check refrigerant levels, coils, fans, and electrical components so we can quickly determine the exact problem and restore proper cooling.
How often should I schedule AC maintenance?
For homeowners in California, we recommend scheduling annual maintenance in the spring before peak summer heat. This ensures your AC is clean, efficient, and ready to handle extended use during the hottest months.
Maintenance typically includes cleaning condenser coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and ensuring the thermostat is calibrated. These steps not only keep your home comfortable but also reduce energy bills by improving efficiency.
Even though California doesn’t have the humidity challenges of the Southeast, dust and dry heat in areas like the Inland Empire can be tough on AC systems. Regular maintenance is the single best way to prevent surprise breakdowns in the middle of a heatwave.
What are the most common AC problems in California?
The most frequent AC issues we see include:
- Low refrigerant (caused by leaks)
- Dirty or clogged filters
- Blocked or leaking ducts
- Failed capacitors, motors, or compressors
- Frozen evaporator coils
- Faulty thermostats
Many of these problems start small but worsen over time, so catching them early saves money and prevents bigger repairs. The hot, dry climate in much of California also accelerates wear on outdoor units, making coil cleaning and electrical inspections especially important.
Should I repair or replace my air conditioner?
If your system is less than 10 years old and the repair is relatively minor, repairing is almost always the best option. However, if your AC is 12–15 years old, breaks down frequently, or uses outdated R-22 refrigerant (which is no longer manufactured), replacement may be more cost-effective.
Newer air conditioners are much more energy-efficient, with higher SEER ratings that lower your utility bills. In California, where AC can be a significant portion of your summer energy costs, these savings quickly add up.
At Daniel’s, our technicians will always provide an honest assessment. If your unit can be fixed affordably, we’ll repair it. If replacement makes more sense long-term, we’ll explain your options clearly so you can make the best choice.
